What is the averageRPM of a propellor on an aircraft? I know it varies so just give examples please?

Question

THANKS FOR ANSWERING!!!!!!!!

Answer 1

FLY B  has it pretty good. It's a good general SWAG.

Answer 2

Piper Cherokee series aircraft (such as the Warrior, Archer, Arrow) typically idle at 500-600 RPM, although recommended idle is at 1000 RPM.  Max RPM is typically between 2500 and 2700 RPM, depending on the specific aircraft.

Answer 3

Ops manual says to idle our Cessna 172s at 1000 rpm, and cruise at about 2300 rpm.

Although... that may be the engine rpms not necessarily the prop rpm...

Answer 4

as a general rule of thumb, most propeller speeds dont go above 3000 rpm to prevent the propeller tips from going supersonic. the larger the propeller, the lower the rpm limit. there have been a few cases of propeller rpm's being above 3000 rpm, but those were experimental designs, and proof of concept designs.

Answer 5

A typical light plane will have max engine and propeller speed of 2500 to 2700 RPM, normal cruise would be between 2100 and 2500 RPM.   A high-power prop plane, like a WWII fighter or a modern turboprop will have a larger, slower turning, prop. A turboprop will have a prop turning under 2000 RPM.

   Generally speaking, the larger the prop, the lower the RPM.  This is because the propeller  tip on a larger prop moves at a higher speed at a given RPM. This is because they have to complete a much larger circle on each revolution.   As the tips of the propeller approach supersonic speed, there is much more drag, wasting the power of the engine.  A propeller tip approaching supersonic speed is also very noisy, as you can start getting shock waves from the tips.
