    en.wikipedia.org/wiki/Gnome_Monosoupape

    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.

    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 ...

    The air intake (inlet U.S. [6]) is an aerodynamic duct extending from an entry lip to the engine fan/compressor. For supersonic intakes with variable geometry it is called an intake system, referring to the need for shock-wave and internal duct flow management using variable position surfaces (ramps or cones) and bypass doors. [7]

    The latest (November 2021) version of the Fairbanks-Morse 38 8-1/8 is known as the FM 38D 8-1/8 Diesel and Dual Fuel. This two-stroke opposed-piston engine retains the same extra-heavy-duty design and has a rated in-service lifespan of more than 40 years, but now the optional capability of burning dual fuels (gaseous and liquid fuels, with ...

  6. Intake ramp - Wikipedia

    en.wikipedia.org/wiki/Intake_ramp

    The first known aircraft to use this is the North American A-5 Vigilante with fully-variable wedge-type side air intakes [3] In the case of Concorde, the first (converging) intake ramp is followed by a diverging ramp. After the air passes the end of the first ramp it has become subsonic such that the diverging ramp further contributes towards ...

  7. Intake - Wikipedia

    en.wikipedia.org/wiki/Intake

    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.

  8. Twin-boom aircraft - Wikipedia

    en.wikipedia.org/wiki/Twin-boom_aircraft

    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.

  9. Dual ignition - Wikipedia

    en.wikipedia.org/wiki/Dual_ignition

    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 ...
