The special configuration of rotor, fixed wing and thrust propellers is employed in the X3 composite helicopter to achieve VTOL and high-speed cruise capability. This paper is based on the momentum blade element theory,and high-precision unsteady flow simulation method to analysis the interference characteristics and predict the noise of the composite helicopter in hover and high speed flight.
