Webb12 okt. 2024 · The fan plot of the test rotor is shown in Fig. 2. It was a Mach-scaled rotor with a nominal speed of 2300 RPM. During the tests, the rotors were slowed down to 700 RPM to obtain high advance ratios. The first flap frequency was 1.21/rev at the nominal RPM and 1.52/rev at the reduced RPM.

The slowed rotor principle is used in the design of some helicopters. On a conventional helicopter the rotational speed of the rotor is constant; reducing it at lower flight speeds can reduce fuel consumption and enable the aircraft to fly more economically. In the compound helicopter and related aircraft … Visa mer Traditional helicopters get both their propulsion and lift from the main rotor; by using a dedicated propulsion device such as a propeller or jet engine, the rotor burden is lessened. If wings are also used to lift the aircraft, the rotor can … Visa mer Technical parameters given for each type listed: • maximum speed. • μ, the ratio of forward airspeed to rotational … Visa mer Speed limits of aircraft rotors The rotors of conventional helicopters are designed to operate at a fixed speed of rotation, to within a few percent.
