X-engine. X-engine cycle. The red line is a three lobe epitrochoid, which is the shape of the LiquidPiston's swept volume. The X-engine is a type of pistonless rotary engine manufactured by LiquidPiston of Bloomfield, Connecticut. The X engine is a hybrid cycle rotary engine.
A Fluidyne engine is an alpha or gamma type Stirling engine with one or more liquid pistons. It contains a working gas (often air), and either two liquid pistons or one liquid piston and a displacer. [1] The engine was invented in 1969. [2] The engine was patented in 1973 by the United Kingdom Atomic Energy Authority. [3][2]
The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litre (1,650 cu in) capacity. Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called Merlin following the company convention of naming its four-stroke piston aero engines after birds of prey.
A 36" cylinder bore Humphrey pump was installed at Chester, Pennsylvania in 1927 by the Sun Shipbuilding and Dry Dock Company. The pump was used in dry dock operations and also for experimental purposes. It was designed as a 2-stroke engine to operate in a range of head from 20 to 150 ft (6 to 46 m).
The IO-550 family of engines was developed from the IO-520 series, with the stroke increased from 4.00 to 4.25 inches, increasing the displacement to 552 in³ (9.05 L). The engine family covers a power range from 280 hp (209 kW) to 360 hp (268 kW). [1][2] The engines were first developed in the early 1980s and first certified on a regulatory ...
Compressed air system with a PCM heat exchanger prototype diagram. A compressed-air vehicle (CAV) is a transport mechanism fueled by tanks of pressurized atmospheric gas and propelled by the release and expansion of the gas within a pneumatic motor. CAV's have found application in torpedoes, locomotives used in situations where standard ...
The work produced by a Fluidyne engine goes into pumping the liquid. In its simplest form, the engine contains a working gas, a liquid, and two non-return valves. [citation needed] The Ringbom engine concept published in 1907 has no rotary mechanism or linkage for the displacer. This is instead driven by a small auxiliary piston, usually a ...
The Orenda OE600 was a 600 hp-class liquid-cooled 8-cylinder V-block aircraft engine intended to re-introduce piston power to aircraft normally powered by the famous Pratt & Whitney Canada PT6 turboprop. The piston engine offers much better fuel economy, which Orenda Aerospace felt would be attractive for older aircraft whose engines were ...
