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 varying with time are analyzed through simplified methods such as preset trajectory and overload.
