Webb20 jan. 2010 · Abstract : A slowed-rotor compound helicopter has been synthesized using the NASA Design and Analysis of Rotorcraft (NDARC) conceptual design software. An overview of the design process and the capabilities of NDARC are presented. The benefits of trading rotor speed, wing-rotor lift share, and trim strategies are presented for an … 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. This introduces … Visa mer • Gyrodyne • Convertiplane Visa mer sharon blessman
