The Monosoupape (French for single-valve), was a rotary engine design first introduced in 1913 by Gnome Engine Company (renamed Gnome et Rhône in 1915). It used a clever arrangement of internal transfer ports and a single pushrod-operated exhaust valve to replace the many moving parts found on more conventional rotary engines, and made the Monosoupape engines some of the most reliable of the era.
A simple form of partial dual ignition on some amateur-built aircraft uses a single spark plug, but duplicates the coil and pick-up for better redundancy than traditional single ignition. [ 9 ] A further form of partial dual ignition (such as on the Honda VT500 ) is for each cylinder to have a single HT coil which sends the current to one plug ...

The first Lockheed DSI was flown on 11 December 1996 as part of a Technology Demonstration project. It was installed on an F-16 Block 30 fighter, replacing the aircraft's original intake diverter. The modified F-16 demonstrated a maximum speed of Mach 2.0 (Mach 2.0 is the F-16's clean certified maximum speed) and handling characteristics ...
If the mass flow across the intake's capture plane does not match the downstream mass flow at the engine, the intake will unstart. This can cause violent, temporary loss of control until the intake is restarted. [3] Few aircraft, although many ramjet-powered missiles, have flown with intakes which have supersonic compression taking place inside ...
A twin-boom aircraft has two longitudinal auxiliary booms [further explanation needed]. These may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces , although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing.
The Rotax 503 is a 37 kW (50 hp), inline 2-cylinder, two-stroke aircraft engine, built by BRP-Rotax GmbH & Co. KG of Austria for use in ultralight aircraft. [ 1 ] [ 2 ] For decades the engine was one of the most popular and reputedly reliable aircraft engines in its class (two-stroke, under 60 horsepower), [ 3 ] and it remains widely used and ...
Aircraft using piston engines use intake systems similar to automobiles. With the development of jet engines and the subsequent ability of aircraft to travel at supersonic speeds, it was necessary to design inlets to provide the flow required by the engine over a wide operating envelope and to provide air with a high-pressure recovery and low distortion.
