Index, bib, ill, p.236.non-fictionIt is difficult to overestimate the excitement that accompanied the birth of the Spitfire. An aircraft imbued with balletic grace and extraordinary versatility, it was powered by a piston engine and a propeller, yet came tantalisingly close to breaking the sound barrier. First flown in 1936, the Spitfire soon came to symbolize Britain's defiance of Nazi Germany in the summer of 1940. Flown by pilots of many nations, it saw service as far afield as Australia and the Soviet Union. Spitfire: The Biography is a celebration of a great British invention.spitfire, world war ii - air warfare

This working-model steam engine was hand-made c.1893 by Frank Scott of Mewburn Park, and used to drive a pump. The entire engine and base were repaired, cleaned and restored by participants in a LEAP program hosted by Eastern Victorian Group Training, Bairnsdale, in June 1995. This included repairing a broken piston arm.This small steam engine has two wheels attached to shafts connected to a single piston. It has a horizontal double-acting three inch bore with a four and half inch stroke fitted with Stephensons link reversing gear. It is mounted on a green-coloured wooden box.engines

This model was found in the collection of Bay Steamers Maritime Museum. It is not knowt who created it but it is supposed that it was constructed to educate the many masters of the Wattle in the operation of a steam engine - a not so common mode of power these days. A Bay Steamers Maritime Museum examined the model in March 2012 and discovered that is was in poor repair. Using his existing knowledge, and with reference to some historic texts, he made some repairs and returned the model to working order. Here is his anaylsis of the situation as an excerpt from the Bay Steamers Maritime Museum newsletter Steamlines May 2012 "I was confronted with a model of a steam engine used years ago as a training aid for hopeful steam engineers. Already having a knowledge of steam operations, I considered a museum write-up for that model a ‘piece of cake’. However, on turning the model’s crankshaft, the valve timing seemed ‘out of kilter’ with the movement of the piston. Problem was that the two eccentrics on the crankshaft were not properly secured to it. Eventually I fastened the two eccentrics to the crankshaft where I felt that they should be and then realized that one of them had a chain-driven valve-timing device attached. This would be adjusted while an engine was running to achieve best performance and fuel economy whilst in operation by accurately controlling the period of time during which steam under pressure from the boiler would be admitted to the cylinder and give greater time for the steam to expand in the cylinder, move the piston and turn the crankshaft and thus, drive the attached apparatus. When the valves were correctly set up it was then possible to get the model to function properly.The model comprises a green section, which is the actual the model mounted on a brown painted board. There are two parts of the model, painted white representing the steam passages, and black representing the cast- iron portions of the cylinder-block casting, and of the main valve sliding between the cylinder a second sliding valve. Of the black portions, one slides back and forth being connected to a rod which is connected to an eccentric clamped to the crankshaft and is the nearer to the flywheel of two eccentrics. This eccentric is attached to the crankshaft at an angle of 90 degrees to the crank-pin attached to the flywheel. To operate the model simply turn the flywheel by means of the handle attached to its crank-pin. A second eccentric is also attached to the crankshaft, further away from the first eccentric, and it is adjusted to operate 90 degrees from the first eccentric (that is, 180 degrees from the crank-pin) A piston (painted silver) is located in a plastic cylinder and has a piston rod which passes through one end of the cylinder, (in actual practice a steam-proof gland seals the cylinder against loss of steam) terminating in a cross-head slide between four rails guiding it. From this cross-head, a connecting rod joins the piston-rod to the flywheel via the crank-pin attached to the flywheel which is part of the crankshaft. (In actual practice, a flywheel may not be used, particularly in a multi-cylinder engine.) The white portions of the model painted nearest to the cylinder represent the two steam ports cast into the main cylinder block, whilst one section painted in between those two represents the exhaust outlet (which may be connected to a condenser to conserve water, or to the open air). The main slide valve has three white-painted portions painted thereon. It has two white-painted marks representing the steam passages to the steam ports into the cylinder, and a third section in between the other two, being that part of the valve through which exhaust steam passes in line with the ports in the cylinder block. By rotating the flywheel, the operations of an engine will be observed as steam is admitted to the main valve via the gap between the two jaws of two moveable portions of a second sliding valve which is operated by the second eccentric attached to the crank-shaft. This eccentric is used to finely tune the valve timing of this model to obtain best running results of an engine. There are various methods used for reversing a steam engine. model compound steam engine, steam engine, model, crankshaft, valve, flywheel, wattle, engineer, eccentrics

This engine was a Commonwealth Aircraft Corporation (CAC) build, and had been upgraded to 92 specification at some time. This engine as acquired, was completely seized and great difficulty was encountered in dismantling it. The pistons in Nos 1, 13, 3, 2 and 5 had "grown" into the cylinder bores requiring some unorthodox methods to remove them. The cylinder barrels have been brought up to a reasonable standard, those beyond repair were replaced from stock. After getting various parts from the US, this engine was eventually brought up to running order.The Pratt & Whitney R 1830 is a double row 14 cylinder air cooled radial engine with a capacity of 1830 cubic inches, (30 litres), developing some 1200 horsepower at a maximum 2700 rpm.Engine Number 54828

Currently on loan to the Puffing Billy Museum at Menzies Creek as an operating exhibit. Blackstone & Co. was a farm implement maker at Stamford, Lincolnshire, United Kingdom. In 1896 they built lamp start oil engines. The Lamp or hot-bulb engine (also hotbulb or heavy-oil engine) is a type of internal combustion engine. It is an engine in which fuel is ignited by being brought into contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb chamber by the rising piston. There is some ignition when the fuel is introduced, but it quickly uses up the available oxygen in the bulb. Vigorous ignition takes place only when sufficient oxygen is supplied to the hot-bulb chamber on the compression stroke of the engine. Most hot-bulb engines were produced as one-cylinder, low-speed two-stroke crankcase scavenged units Historic - Industrial - single cylinder, horizontal, 4 stroke, hot-bulb ignition oil engine Blackstone 8HP Oil Engine made from steel, wrought iron and brassOval Plate with Black Stones and Clutter Buck Brass Plaque engine number 71076blackstone, oil engine, clutter buck, black stone, puffing billy, hit and miss, engine, blackstone & co

Louis Heinrici, Germany, circa 1900 a small Stirling type hot air engine in which a body of air is worked constantly, being alternately heated and cooled during each revolution of the crankshaft. Heinrici hot air engines are of the valveless, closed cycle type, generally called Stirling cycle engines, after Robert Stirling, the Scottish Presbyterian minister who pioneered their development in the early 1800's. They operate by alternately heating and cooling a quantity of air, called the working fluid, contained in the engine's internal spaces. Heat is applied externally and passes through the cylinder wall, heating the working fluid, which is then expanded against a piston to do mechanical work. After heating and expanding, the working fluid is moved to a cool space where it cools and contracts before being returned to the hot space for the cycle to repeat. It has a displacer (just a loose piston), below and in the same cylinder as the power piston to which it is connected via cranks and linkages so as to lead by 90degrees of crankshaft angle. The displacer space and the piston space are connected by the annular gap around the loose fitting displacer so that the working fluid moves between these spaces and changes volume by the appropriate ratio as the engine rotates. Because they have no valves and experience no sudden pressure changes, Stirling engines are noted for quietness and reliability. Heinricis use air at atmospheric pressure for their working fluid, but for higher specific output (power for size) and better efficiency, modern Stirling cycle engines use pressurised gas- air, nitrogen, helium or hydrogen.Historic - Hot Air Engine - MotorHot Air Motor made of Steel with two drive wheels. a small Stirling type hot air engine in which a body of air is worked constantly, being alternately heated and cooled during each revolution of the crankshaft.
