Frequent question: How do rc jet engines work?

How much does an RC jet engine cost?

Prices for jet engines range from $2,000 to $4,500 and up, depending on size and accessories. Like their full-sized counterparts, model engines take air into a combustion chamber using compressor blades. There, fuel burns and the escaping exhaust turns a power turbine and provides thrust.

Do RC planes have real jet engines?

Before model jet engines appeared on the scene, rc jets always lacked the authenticity of having a true gas turbine. Previously radio control jets had to be powered by either an engine with a propeller (thus spoiling the look of the aircraft) or ducted fan units.

What fuel do RC jets use?

RC glow engines use nitro fuel, a methanol-based fuel with nitromethane and oil added. The amount of nitromethane in the fuel is typically about 20% but could be anywhere in the 10% to 40% range or higher. Castor oil or synthetic oil is added to the fuel to provide lubrication and cooling.

How much thrust does a small jet engine produce?

The thrust of a typical jetliner engine went from 5,000 lbf (22,000 N) (de Havilland Ghost turbojet) in the 1950s to 115,000 lbf (510,000 N) (General Electric GE90 turbofan) in the 1990s, and their reliability went from 40 in-flight shutdowns per 100,000 engine flight hours to less than 1 per 100,000 in the late 1990s.
