In view of the insufficient research on the dynamic nature and stall characteristics of stall helix of aircraft, the causes of stall helix and stall helix are analyzed. The kinematic characteristics of stall helix are analyzed from three stages of stall helix entry, steady and retrofit. The formulas for calculating speed, radius, height and time of stall helix motion and six freedoms are derived by force balance method. The degree kinematics equation and the simulation model of the steady-state plane helix are built on the platform of MATLAB/Simulink. The real-time attitude and trajectory of the airframe during the stall helix process can be observed directly by the simulation. The difficulty of obtaining the steady-state state state of the aircraft during the stall helix process can be solved. The simulation results show that the model and the method used are reliable and reliable. Practicality, the relevant methods can also be applied to the study of other types of steady stall helix. The research results can provide reference for relevant pilots and lay a theoretical foundation for safe flight and avoidance of spin.
