Rpm of helicopter blades
WebThe same thing happens during rotor stall with a helicopter except it occurs due to tow rotor RPM instead Of low airspeed. AS the RPM Of the rotor gets lower, the angle-of-attack Of the rotor blades must be higher to generate the lift required to support the weight of the helicopter.

WebThe fan and low-pressure compressor of a big airliner engine run at between 2500 and 4000 RPM, and the turbine of the PT-6, a classical turboprop engine, at 30.000 RPM. Since power is torque times RPM, a faster running shaft will be lighter than one running at low speed, so the speed is only reduced directly at the propeller mount.

WebTail rotor. The tail rotor is a smaller rotor mounted vertically or near-vertically at the tail of a traditional single-rotor helicopter, where it rotates to generate a propeller -like horizontal thrust in the same direction as the main rotor 's rotation.

That seems low ( normal head speed for a T-Rex 500 is 2500-3000rpm) but we're calculating the absolute lowest speed to hover, with the blades right on the edge of a stall, while this sort of heli is designed for aggressive aerobatics.
