General Electric turbocharger model B-22 was fitted externally to a Pratt & Whitney R1930 14 cylinder twin wasp radial air-cooled engine for the supply of air at an increased pressure to the carburetor intake. This enabled the B-24 Liberator to maintain a maximum 1300HP at takeoff from sea level to 30,000 ft. ceiling and at high altitude.Round metal supercharger with inlet and outlet.General Electric turbo super charger.

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.

Citation of Distinguished Flying Cross awarded to JOHN HUDSON WILKINSON: Service Number - 400444 : Date of birth - 18 Feb 1914 : Place of birth - RUTHERGLEN Victoria - tragically killed in action over Germany on 30th August, 1944. Citation reads: - "Pilot Officer WILKINSON is an air gunner of great ability and determination. He has taken part in a large number of operational sorties, many of which have been against some of German's most heavily defended targets. On one occasion, in March 1944, when engaged in an attack on Stuttgart, a Junkers 88 attacked the aircraft five times, but Pilot Officer WILKINSON, by his accurate directions to his captain and coolly aimed return fire, drove off the enemy aircraft in a badly damaged condition. At all times his unwavering devotion to duty and constant alertness have inspired confidence in his crew." The Distinguished Flying Cross (DFC) is the third-level military decoration awarded to officers, and since 1993 to other ranks, of the United Kingdom's Royal Air Force and other services, and formerly to officers of other Commonwealth countries, for "an act or acts of valour, courage or devotion to duty whilst flying in active operations against the enemy"Original typed document on blue/grey parchment with blue letterhead containing crestGovernor General Commonwealth of Australiapilot, kia, killed in action, dfc, distinguished flying cross, wwii, world war two, air force, wilkinson
