The compound helicopter configuration and the helicopter speed trap

Abstract

Explains the origins of rotor aerodynamic limits for helicopters including retreating and advancing blade limits. Examines the compounding of a helicopter for higher forward speed and reports the conclusions of a student project to design a rotorcraft capable of 300 knots and carrying a payload of 30 passengers.
