Radio-control jets require an onboard FADEC (full authority digital engine control) controller; this controls the turbine, as on a full-size aircraft. RC jets also require electrical power. Most have a lithium polymer (LiPo) battery pack at 8–12 volts that controls the FADEC. There is also a LiPo for the onboard servos that control ailerons ...
A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket , water jet , and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet , turbofan ...
All jet engines require high temperature gas for good efficiency, typically achieved by combusting hydrocarbon or hydrogen fuel. Combustion temperatures can be as high as 3500K (5841F) in rockets, far above the melting point of most materials, but normal airbreathing jet engines use rather lower temperatures.
Argus As 014 (aka "Argus 109-014") – pulse jet engine for V-1 flying bomb and Tornado boat Argus As 044 [ 37 ] Argus As 16 4-cylinder inverted inline 40 hp [ 37 ]
Four-stroke model engines have been made in sizes as small as 0.20 in3 (3.3 cc) for the smallest single-cylinder models, all the way up to 3.05 in3 (50 cc) for the largest size for single-cylinder units, with twin- and multi-cylinder engines on the market being as small as 10 cc for opposed-cylinder twins, while going somewhat larger in size ...
One was the jet-powered BD-5J, which boosted performance to 305 knots (565 km/h; 351 mph). [1] There was an attempt to sidestep the engine problem with the BD-5S glider (S for Sailplane), with lengthened wings and no engine, which prompted Air Progress magazine to sarcastically note, "At last, a BD-5 with no engine problems."
The engine casing of the early motors is made of an aluminium alloy. On introduction, fuel pellets and wick could be purchased separately, meaning that the system is reusable. [2] Jetex power made a big impact in the late 1940s and early 1950s, allowing new sorts of models, scale and duration, to be designed.
The XF-12 was referred to as "flying on all fours" meaning: four engines, 400 mph (640 km/h) cruise, 4,000 mi (6,400 km) range, at 40,000 ft (12,000 m). [1] The aircraft was designed to maximize aerodynamic efficiency. Although innovative, the jet engine and the end of World War 2 made it obsolete
