Otto Lilienthal (1848-1896) from Berlin, Germany, is widely credited as being the first person to make repeated successful gliding flights. He was known for adopting a thorough scientific approach founded on observations of the flight of birds in relation to the problem of inventing a man carrying heavier than air machine that would fly. He developed and tested bird-like gliders controlled by weight shift by the pilot (a similar method to modern hang gliders). The pilot held on to the glider with his forearms resting in hoops mounted on the main structural beam connecting the wings. The weight shift was achieved by the pilot swinging his trunk and legs. In contrast, the pilot of a modern hang glider is suspended below the glider and, with the use of an A-frame, allows the whole body to be moved around to achieve control. The Lilienthal design apparently had a tendency to pitch down and a tailplane was added to mitigate this problem. Lilienthal flew from hills in the Rhinow region and from a conical hill he built near Berlin. He made over 2000 flights. Importantly, for others seeking to progress manned flight at the time and also for the historical record, reports of Lilienthal’s flights (some with photographs) were published and Lilienthal detailed his experiences and corresponded with other flight pioneers. Lilienthal’s work became well known and influenced Orville and Wilbur Wright in their initial experiments with gliders in 1899 (although in their quest to design and fly an aeroplane they relied on new data created by wind tunnel testing). The replica built by Bruce Hearn is of the 1893 Lilienthal glider. It is very similar to the “Normal-Segalapparat” (Normal Glider) for which patent protection was later granted a few years later. The Lilienthal replica glider is an important addition to the AGM collection as it represents the beginning of successful gliding flight.

The Bocian is a versatile training sailplane that first flew in 1952. The type has been modified in several respects over the course of production by SZD (tailplane and rudder in particular). About 600 have been built; many for export to 27 countries (including Australia). The aerobatic capability and fine performance (best glide ratio of 26) has enabled the Bocian to be used to train competition pilots as well as those of lesser experience. Many world gliding records were set in the 1950s and 1960s in Bocian gliders. The Museum’s example is a type D test flown in Poland on 3 and 4 April 1963. It was imported into Australia in September 1963 by Austerserve Pty Ltd. The first owner was the Alice Springs Gliding Club and the glider had name “Cumulus” painted on the side of the fuselage (since removed). The glider had recorded 726 hours 46 minutes flying time from 2138 launches as at July 1967 when it was transferred to the Darwin Gliding Club. It appears that the glider was damaged in June 1968. The substantial repairs to the fuselage, both wings and tailplane and other minor repairs were completed on 13 October 1968. The glider continued flying with the Darwin Gliding Club until August 1969 at which time the service to that club amounted to 59 hours 7 minutes flying time from 348 flights. Between August 1969 and August 1976 no flights are recorded in the logbook. It is understood that on its last flight at Bachelor, south of Darwin in the Northern Territory (August 1969) it was severely damaged when it crashed after spinning while being auto-tow launched (although this is not expressly mentioned in the logbook). Reg Hancock purchased the damaged glider and rebuilt the port wing and restored it to airworthy condition (September 1976). It was then transferred to Colac, Victoria, and used by the Colac Gliding Group at the Yeo airfield until February 1981, adding another 153 hours from 403 flights to the glider’s record. After airworthy inspection in September 1982 the glider was used by the Geelong Gliding Club until 1983 (logbook details not held). The 20 year survey was then due and the glider fell out of service. In the course of the most recent restoration attempt it was discovered that the glue used in construction had deteriorated and that it was no longer feasible to bring it back to an airworthy condition. Subject to restoration, this exhibit may be representative of the 1950s - 1960s Bocian two seat sailplane typeThis exhibit is a large two seat glider /sailplane of wood and fabric construction. All components are present with the exception of instruments. However, at the time that the aircraft was transferred to the Museum it had been taken apart for major restoration work. As received it is stripped of the top coats of paint and a number of components (including, amongst others, tip fairings, nose cone and cockpit elements) that were removed for facilitating the repair process.

The Alexander Schleicher K4 was designed in the mid 1950s by Rudolf Kaiser as a club training glider and several hundred were built. The Australian Gliding Museum’s K4, VH-IKK, serial number 55, was built in 1957 and purchased by the RAF Air Training Corp. U.K. After some years it was sold to a New Zealand Gliding Club and in 1990 with over 4800 hours, number of launches unknown, it was purchased by the Brisbane Valley Soaring Club and in 1994 was transferred to the Far North Queensland Soaring Centre who operated it from the Mareeba airfield. On 9 January 2000 it was donated to Vintage Gliders Australia by Kevin Sedgman at a presentation ceremony with Alan Patching receiving the glider during the Rally at Lake Keepit. It has been flown regularly at vintage glider rallies and on several occasions at Museum open days. However, it has subsequently been grounded on account of potential structural defects. VH-IKK is one of two K4s in Australia, the other being VH-XJP which is believed to be in storage in Queensland in a damaged condition. When restored, this exhibit will be representative example of the AS-K4 glider-sailplane type.Tandem two seat high wing strutted glider consisting of wood with plywood and fabric wings, tailplane / elevators, fin / rudder, and tubular steel framed, fabric covered fuselage.

The original “Taylor glider” was the aircraft used by George Taylor for the first heavier than air flight in Australia, which occurred on the 5 December 1909 on the beach at Narrabeen, New South Wales. On that historic day the glider was also flown by Edward Hallstrom, Charles Schultz, and Mrs Taylor and Mrs Schultz. The replicas were built by the Museum to celebrate the centenary of the first Australian heavier than air flight. The glider is an accurate full size replica of George Taylor’s Glider.Wooden frame, wire braced and fabric covered biplane hang-gliderNoneaustralian gliding, glider, biplane, george taylor, edward hallstrom, charles schultz, narrabeen, first flight

The “Northrop” is an American copy of the “Zogling” which was designed in Germany in the 1920s as a training glider. Apparently, the Northrop primary glider takes its name from a Marvin Northrop of Minneapolis who imported a Zogling from Germany and from that glider had plans drawn and published in a magazine called Modern Mechanics in 1930. The Australia Gliding Museum’s Northrop was built over the period of 1970 to 1974. The project was conceived by a pioneer of Australian gliding, Ken Davies, about 1969, as a hobby project and to experience afresh gliding flight of the early years. By that time, few primary gliders, which performed a fundamental role for gliding clubs in the 1930s and 1940s, remained in Australia. Ken began construction and was helped to finish the project by two old time Gliding Club of Victoria members, Dave Darbyshire and Rudi Feil. The glider was test flown on 8 March 1975 at Benalla. The glider was stored at the Gliding Club of Victoria and flown on special occasions in the 1980s. Later it was damaged at the 1996 vintage glider rally at Ararat as a result of a heavy landing. Storage was then provided for the glider by the Victorian Motorless Flight Group at Bacchus Marsh until it was returned to Dave Darbyshire for restoration in 1998. Fully restored, the glider was donated by Iris Davies and Dave Darbyshire to the Australian Gliding Museum in April 2001. This exhibit is the type of machine that formed the basis of the sport of gliding from 1929 to about 1945. The glider consists of an open (uncovered) wooden framed fuselage (painted blue) with a brown vinyl covered seat, fabric covered wooden framed wings of constant chord (painted silver) with provision for attachment of semi-circular cane wing skids, and fabric covered wooden framed tailplane, elevators and rudder (painted silver). When assembled the airframe is wire braced.australian gliding, glider, northrop, zogling, davies, darbyshire, feil, gliding club of victoria, victorian motorless flight group

The Salamandra is a Polish glider designed by Waclaw Czerwinski at the Military Glider Workshops in Krakow in 1936. This glider, designated “W.W.S.1”, was produced in substantial numbers prior to the second world war and used in Poland and some other eastern European countries for training pilots. Only one example survived the war, hidden away in the village of Goleszow in Silesia. In addition, no technical drawings could be found, so when the glider was discovered, the Gliding Institute being keen to re-establish gliding in Poland, used the glider to draw up new plans for construction. Five were built for the Institute in 1947 before production was resumed of the “Salamandra 48” at the SZD Jezow Workshops. Improvement were made by adding airbrakes and structural changes for the “Salamandra 49” and a windscreen and larger tailplane were changes adopted for the “Salamandra 53”. An export version designated “53A” was sold to and built under licence in China. Production of the Salamandra ceased in the early 1960s. Total production may have been in excess of 500. The glider was well regarded as a light weight trainer capable of soaring performance. The Museum’s replica was built by Ray Ash and may be may be classified as a “Salamandra 53”. However, he has added something of his own to the design by replacing the cable runs in the wings with control rods. The glider is substantially complete. The wings and tail / rudder surfaces have been covered with poly-fibre fabric. The fuselage woodwork is sealed with varnish. In addition to the finishing work (including painting) and rigging of the main components, the linkages for Ray’s control rod modification may need further engineering to make them operational. The Ray Ash Salamandra is the first of the type to appear in Australia. The Salamandra did not play any role in the development of gliding in Australia in the early years. However, it is an important exhibit in that it shows in tangible form a nacelle fuselage training glider in configuration and construction detail. As such it revisits the pioneering era of the 1930s and 1940s in Australia when wood, wire and fabric were the rule and the nacelle primary glider was generally the first step up for pilots who had mastered the basics in an open primary.Nacelled solo training glider of traditional wood and fabric construction.

The Geelong Glider Club was formed in June 1929 at a meeting held at the Belmont Common hangar of Percy Pratt. The club built a Zogling (Primary Glider) based on plans obtained from Germany and flew it off nearby hills at Lovely Banks and other places in the Geelong region. The checked rudder design (without logo and markings) is evident in a picture of a Geelong Glider Club Zogling flying at Tower Hill near Warrambool, Victoria, at Easter 1931 and this lends support to the conclusion that the rudder was part of the Club’s first glider. The logo and markings appear to be a more recent elaboration to the design. Exhibit is a historical link to the earliest gliding activities of the Geelong Glider Club.Fabric covered wooden framed primary glider rudder with metal levers decorated with silver and dark red checkered design.

The Schreder HP 14T is a variant of an all metal single seat sailplane designed by Richard Schreder of USA in the 1960s. The HP14T featured a ‘T’ tail in place of ‘V’ tail of the HP14V. The design was marketed to home builders in kit form. The Museum’s Schreder HP14T (VH-GIB) first flew on 31 August 1974. It has recorded 280 hours in the air from 239 launches to 28 January 1989, the date of its last flight. It is understood that VH-GIB was partly constructed in North America and completed in South Australia by C.G.M. Coxon. Ownership passed to the Georgeson Syndicate of Rockhamption, Queensland and later to Warren Mayfield of Victoria. Warren Mayfield donated the glider to the Museum in April 2002.

The Ka 8 was designed by Rudolf Kaiser in 1957 and built by Alexander Schleicher. It has been described as the single seat version of the Ka 7 Rhonadler. The Ka 8 proved popular with clubs in its role as a sailplane for early solo flying. Over 1100 were produced. The Museum’s example is a Ka 8B which is the second variant of the design, distinguishable by a larger blown Plexiglas canopy and improved ailerons. The particular glider was built by the RAAF Williamtown Gliding Club from kit supplied by Edmund Schneider Ltd of South Australia as agent for Alexander Schleicher. It was test flown on 8 July 1967. For a period from August 1994 it was owned by a syndicate at the Bendigo Gliding Club. The last entry in the log book is dated January 1995 at which time the glider had accumulated 1148 hours from 2303 flights. From 1967 to 1994, the glider was flown at numerous places including Williamtown, Bellata, Warkworth, Dubbo, Waikerie, Quirindi, Tamworth, Redding, Narromine, Leeton and Keepit. During 1994 and 1995 it was flown a small number of times at Bendigo. A notable flight recorded in the logbook is dated 31 October 1971 when W. Kenny reached 11,000 feet in height during a flight of 5 hours 10 minutes. The last owner prior to the transfer of the glider to the Australian Gliding Museum in 2015 was John Ashford of the Geelong Gliding Club. The glider carries Serial Number 8478-SH and appears to have been registered firstly as VH-GPA and secondly as VH-GMA. The last registration (VH-GMA) was cancelled in 2011.This Kaiser Ka8B sailplane, when fully restored, will be an airworthy example of a popular 1960s German club sailplane type. It is a rarity in Australia as only 4 of the type have been registered and flown here.Single seat sailplane made with a steel tube framed fuselage and wooden wings.

The aircraft was built in 1957 by Cliff Brown. It is an EPB 1, a 26 foot tailless sailplane designed in United States by Al Backstrom, Phil Easley and Jack Powell in 1954 as a simple, cheap, compact craft.A small number of single seat gliders of this type were built in Australia in the 1950s. As far as is presently known, the only surviving substantially complete EPB 1s are Cliff Brown’s glider and another held by the RAAF Association at Bull Creek in Western Australia. Unfortunately, no trace exists of the Flying Plank built by Glidair Sailplanes in Sydney and test flown by Fred Hoinville at Moorabbin in 1957. In addition, a larger two seat derivative (known as the Twin Plank) designed and built by Glidair Sailplanes (completed 1958) is held at the Power House Museum, Castlehill, in Sydney.

This Grunau Baby 2B glider, often referred to as the “Blue Grunau”, was built by Australian Sailplanes in 1946 and acquired by a syndicate consisting of Norm Hyde, Rob Dowling, Leo Dowling, Dick Duckworth and Ted Desmond of the Gliding Club of Victoria. Piloted by syndicate members and other GCV members the glider performed well in soaring and cross country flights at the various sites used by the GCV in 1947, 1948 and 1949. The glider went to Sydney for a while and then returned to be operated by another syndicate at the GCV. Pat Burke and Bob McAliece bought the glider in the 1950s and then sold it to Keith, Jack and Bruce Hearn of Melbourne. In 1957 the Blue Grunau moved to Western Australia and was added to the Glider Register as VH-GLC. Thereafter the glider had a series of owners. The glider has come to the Australian Gliding Museum via the RAAFA (WA) Division. The flying record of the Blue Grunau has been logged for the period of 28 December 1957 to 17 September 1975: Time in air – 559 hours 37 minutes from 1513 flights.

MOBA2 is a 15 metre sailplane designed by Gary Sunderland, who was an aeronautical engineer working for the Department of Civil Aviation (Australia) and a member of the Victorian Motorless Flight Group (VMFG). The design gave effect to ideas that he developed circa 1970 for an aircraft that he could build himself. He entered a 13 metre wingspan version of his MOBA design (MOBA2B) in an Australian Gliding sailplane design competition that was announced in 1970. The competition called for sailplane designs with a maximum wingspan of 13 metres that could be built by amateurs in a small workshop with limited tools and facilities. In 1973, Gary’s MOBA was judged by the competition panel as equal best with the other outstanding submission, which were chosen from a field of 19 entrants. However, after gathering further information and deliberation by the competition panel neither of the two outstanding designs were chosen as the winner. Notwithstanding the outcome, in 1974 Gary proceeded built his glider to the original 15 metre design. The wing was equipped with camber changing flaps that were permitted under special standard class rules for the 1974 world championships. Changes were made along the way in the light of construction experience and the completed glider was given the designation MOBA2C. The glider first flew on 12 December 1979. It was never flown in standard class competition as by the time the glider was built the special 1974 rules were revoked and wing flaps were no longer permitted in that class. However, Gary flew MOBA2C in the Australian national gliding competitions held at Benalla in the summer of 1979 / 1980 competing in the open class. After adjustment to the aileron gearing during initial trials MOBA2C was found to fly well and in competition produced performances believed to be better than contemporary standard class sailplanes but not as good as the open class machines. The glider was later modified in a number of respects including amongst other things the installation of spoilers located just forward of the wing flaps and by increasing the chord marginally at the wing root. With these changes the glider type was given the designation MOBA2D. The last recorded flights occurred in February 1996 at which time MOBA2 had flown an aggregate of 401 hours and 59 minutes during its 297 launches. Its operational life was brought to an end due to expansion of the foam in the wings causing distortion of the wing surface.The MOBA2 is a notable home built 1970s sailplane design that featured a number of innovative elements including composite construction without the need for expensive jigs, nose cone canopy and asymmetrical placement of control column.Composite single seat glider / sailplane finished in bright yellowRegistration "GVI" on fuselage; Kangaroo, Australian Flag and VMFG decals on vertical stabiliseraustralian gliding, glider, sailplane, moba2b, moba2c, sunderland, moba2d, victorian motorless flight group, vmfg

The ES52 Kookaburra is a two seat high wing glider – sailplane of wooden construction designed by Harry Schneider and built Edmund Schneider Pty Ltd. It was first flown on 26 June 1954 and became the glider of choice for training new pilots of many gliding clubs around Australia in the 1950s, 1960s and 1970s. Several found there way to New Zealand. Further two kits were sent to Brazil and at least one of these was finished and flow successfully. The ES52 performed well with a glide ratio of about 22:1 and had soaring and cross-country capabilities. A notable feature of the ES52 design was the staggered side-by-side seating arrangement of the cockpit. This made for good in flight communication between instructor and trainee. Overall, thirty six were built by Edmund Schneider Pty Ltd. A longer wing version (the ES52B) was also introduced that had a better glide ratio (around 25:1). Five examples of this version were built. In Germany a modified ES52 was built incorporating a metal tube fuselage frame and with the addition of a engine driven propeller mounted on top of the wing which enabled the glider to be self launching. This museum collection item consists of the fuselage, tailplane, elevators, fin, rudder from the Mark I, ES 52 Kookaburra, formerly registered as VH-GFF and last owned by the Barcaldine and District Airsports Club of Queensland. The glider was in a damaged condition when it was acquired by the Museum. A decision was made by the Museum to repair the glider for display rather than endeavouring to restore it to an airworthy condition. The reconstruction of the wings is being undertaken by using parts of damaged ES 52 Kookaburra wings (as it happened from later ES 52 Marks). The Log Book for VH-GFF reveals operational life with a succession of gliding clubs around Australia. This exhibit will be of interest to gliding enthusiasts wishing to inspect the popular two seat club trainer of a by-gone era.This is a wood and fabric covered aircraft that is being rebuilt from the components of several aircraft as a non-flying exhibit.Fuselage marked with Edmund Schneider Pty Ltd Serial Number 9 and comes from the glider previously registered as VH-GFF.australian gliding, glider, sailplane, edmund schneider, es 52, kookaburra, barcaldine and district airsports club, victorian motorless flight group, alice springs gliding club, raaf richmond, raaf williamtown, gayndah gliding club, blackwater gliding club, southern downs aero and soaring club, charleville gliding club

The FS-24 Phonix is the first sailplane design to be built using a moulded fiberglass sandwich technique. It was designed by Hermann Nagele and Richard Eppler leading a group setup for the purpose at Stuttgart Technical University in the early 1950s. Initial construction was undertaken at workshops of Wolf Hirth and the first prototype was completed at the Bolkow Aircraft Company where Nagele and another member of the group, Rudi Lindner, had gained employment. It flew on 27 November 1957. Two further prototypes were built incorporating a T-tail and other refinements. Eight in all were built before production was stopped in 1961. A number of gliding records were broken in Phonix sailplanes in Germany in 1962-1963. It was found to have a best glide ratio of 40:1. The Museum’s example, No. 403 was originally a prototype built on 25 May 1960 [Registration D-8354]. It was converted at Bolkow to a Phonix T in 1963 and sold to a private owner in Switzerland [Registration HB-746] and later then to gliding club Segelfluggruppe Solothurn in 1965. The glider returned to Germany in 1971 (Meersburg) and re-registered as D-0738. It moved to a new owner in Allershausen in 1976, and again to Lindhoft in 1982. In 1983 the glider was sold to owners at Hasselt, Belgium and given registration OO-ZQD. In 1989 a further change of ownership occurred and the glider went to Leusden in the Netherlands where it was registered as PH-949. In 2006 the Phonix No.403 was imported into Australia by John Ashford of the Geelong Gliding Club. On 30 January 2007, it was registered as VH-GRP. However, as at January 2016 it has not been flown in Australia. In the course of its flying history the glider was damaged several times and repaired. At one stage a larger rudder was fitted and later on this modification was reversed. With the original conversion to a Phonix T and subsequent repairs and changes to equipment the weight of the airframe increased from 182 kg to approximately 220 kg. Nevertheless, the wing loading is a modest 20kg/square metre. As at January 2016, minor repairs and airworthiness certification are required to return the glider to flying condition. This exhibit is highly significant as it is one of only eight of this pioneering sailplane design. It is the only one in Australia.

The aircraft (Serial Number 159 – registration VH-GNT) was assembled by RAAF Richmond Gliding Club from a kit manufactured by Schweizer Aircraft Corporation, Elmira, New York State, USA, in 1963. First flown 21 December 1963. Served at RAAF Base, Richmond, NSW, until December 1978 at which time it had recorded 1981 hours from 9870 flights. The aircraft was sold to Peter Fitzgerald and moved to Gosford and later on, to Queanbeyan where it was stored under cover until April 1983. It was not flown between 1978 and July 1983. In 1983 the glider was sold to Harold Walton. A Certificate of Airworthiness inspection was done by various members of the Canberra Gliding Club where minor repairs were made. On 24 July 1983, it first flew on the airworthiness certificate test flight at Bunyan, NSW, the home of the Canberra Gliding Club. In service at Bunyan until November 1986 the hours flown increased to 2078 from 10249 flights. A certificate of airworthiness inspection was completed on 11 April 1987 but the aircraft was apparently only recorded a few more hours by 9 January 1998 when it last took to the air. When donated to the Australian Gliding Museum in January 2020, the aircraft was in storage at premises of the donor, Harold Walton, at Walkerville, South Australia.This aircraft is the only one of the 258 SGS 2.22s produced by Schweizer to come to Australia. It is a good representative example of the SGS 2.22 type which featured metal construction for production of a robust club trainer.

This aircraft was designed by Edmund Schneider as a single seat medium performance sailplane. Originally designated as the Grunau 3b but later named the Grunau 4. However, it was a new design with fully enclosed cockpit. The main point of difference to earlier Schneider Grunau designs was the tapered wings with the Gottingen 549 aerofoil. This design feature gave the Grunau 4 a better speed range compared to the Grunau Baby 2b or the Grunau 3. The prototype flew on 6 December 1953 and it went to the Waikerie Gliding Club. A second was delivered to the Dubbo Gliding Club in October of the next year and a third (the Australian Gliding Museum’s exhibit) built for the Adelaide Soaring Club in 1959 (registered as VH-GLX on 21 October 1959). Another was built by Josef Brabec from a Schneider supplied kit from 1954 to 1956. The log book indicates that the glider recorded 2362 flying hours over approximately 40 years of active service. There are many long flights recorded. The registration was cancelled on 30 July 2014 as a result of a decision by the Museum to withdraw the glider from service. The exhibit represents the final development of the "Grunau" single seat type by Edmund Schneider Ltd in Australia. Viewed together with the Grunau Baby gliders in the ATO Collection (Two Grunau Baby 2, and a Grunau Baby 3A), the changes to this glider type over a 30 year period can be recognized.
