Abstract

In this paper, a rigid body motion model is used to superimpose the aerodynamic forces and moments of various parts of the helicopter (rotor, fuselage, tail, etc.) on the centroid of the helicopter. An aerodynamic model for the pop-up process of a coaxial rigid helicopter is established. Taking the XH-59A helicopter flying over obstacles in vertical plane in the specified time as an example, the control parameters (rotor collective pitch, cyclic pitch and engine power) varying with time are analyzed through simplified methods such as preset trajectory and overload. The helicopter attitude angle, speed and power are analyzed with flight performance predicted. The CFD model of XH-59A helicopter rotor is also established and verified to facilitate the development of subsequent research.
