How do RC model jet engines work?
Model Jet Engine Operation In a centrifugal flow unit, air entering the turbine is thrown outwards as it passes over the spinning impeller, or compressor. The air hits against the inside of the body (can) at great speed and so gets highly compressed as it passes into the combustion chamber.
How are RC Jets powered?
The motor spins the impeller at very high RPM (revs/minute). As it spins, the impeller draws air in through one or more forward-facing air intakes in the fuselage of the jet, and then forces the air down a cylindrical thrust tube and out the back of the jet.
How high can a RC plane fly?
34,800 ft
The highest altitude remote-controlled (RC) model aircraft flight is 10,607 m (34,800 ft), and was achieved by Paul Kaup, Jake Minker, Nick Ross, Eric Gordon, Rachel Stark, and Dani Deckert (all USA) in Truth or Consequences, New Mexico, USA, on 13 October 2019.
How much thrust does a model jet engine produce?
With engine thrusts of up to 45 lb, the performance of model jet aircraft is impressive. Many fly at over 200 mph and can accelerate in vertical climbs.
What kind of fuel do RC jets use?
Most RC cars and trucks use 10%-40% nitro blends. RC airplanes may use lower nitro blends of 5%-10% nitro. There are also RC engines that run on regular gasoline mixed with motor oil or diesel fuel (these are engines with spark plugs rather than glow plugs) as well as jet-turbine engines that use propane or kerosene.
What size engine do I need for my RC plane?
RC plane manufacturers commonly specify two different engine sizes for their planes – one for each engine type. It’s worth noting that, because 2-strokes produce more power for their size than 4-strokes, a 4-stroke engine size recommendation will always be bigger. For example, a ’46’ size 2-stroke could be replaced with a ’61’ size 4-stroke.
What is the size of a model airplane engine?
Model airplane engine sizes. All glow plug rc model aero engines, whether 2-stroke or 4-stroke, are expressed as a certain size. This size refers to the engine’s capacity in terms of 1/100th of a cubic inch but is usually expressed as just the number eg a .40cu.in. engine would be referred to as a 40 and a .61cu.in.
What are the parts of RC airplanes?
The RC electronics (motors, servos, batteries, wiring) are often housed inside the fuselage. Some RC airplanes have little more than a long stick or rod for a fuselage. Wing: Airplanes are called fixed wing aircraft. Attached to the fuselage, the wings don’t usually flap or turn.
What types of model airplane engines are used for radio control?
When talking about model airplane engines for radio control use, by far the most common type is the glow plug engine, often also called a nitro or even gas engine.
