Based on MATLAB simulation technology,a forced landing model without power is established for a certain aircraft.With the help of this flight simulation model,the process of forced landing can be simulated,the influence associated with various factors on the ability of forced landing during the unpowered hover and glide can also be analyzed.The results of simulation calculation indicate that setting proper parameters can be beneficial to maximize the range of forced landing.Meanwhile,considering the influence of wind in the actual atmospheric environment,different divisions of energy range of forced landing are proposed.The research method can effectively estimate the ability of forced landing without power.
