What is the rpm of motors used in aircraft.?

Answer 1

although you didn't mean what kind of ac you concerned, let me give you some numbers about rolls-royce trent engine: thrust is 95 000 lbs.

it has three shaft (the features of RR, I haven't seen this 3 shaft combination in any other engines), N1, N2 and N3 so that low pressure, intermediate pressure and high pressure.

LP = 3000 RPM

IP = 7500 RPM

HP = 10000 RPM

the other jet engines have numbers similar to that levels...

Answer 2

Depends on the type of aircraft and whether the engine drives a propeller or uses jet thrust to power the aircraft.

Your average propeller looses efficiency at over 2800 RPMs, so a direct drive piston engine (Cessna, Piper, Mooney, etc.) will turn slower than that.  A turbo-prop engine uses a prop speed reduction unit (gearbox) so the turbo-prop engine can spin up to over 10,000 RPM, while keeping the prop speed below 2800.  

A pure jet engine is almost unlimited for RPM, as the only restriction is the compressor speed...  Some can run over 25,000 RPM.

Answer 3

A Garrett/Allied Signal/Honeywell TPE-331 turboprop engine turns just shy of 42,000 rpm at 100%. They are a single shaft engine. The compressor and turbine wheels turn the same speed. Depending on the model of engine the speed was reduced to 2000 rpm for 2 bladed props and just shy of 1600 rpm for a 4 bladed prop when used on a Mitsubishi MU-2, Turdo Commander, or King Air B-100.

Answer 4

Each engine has their own maximum limits, it's entirely up to the manufacturer of the engine

Answer 5

In a Cessna 150, with a 100HP piston engine, top RPM is 2500 RPM
