The invention provides a fitting method and system suitable for stealth aircraft post-stall maneuver, computer equipment and a readable medium. The method comprises: sequentially generating post-stallmaneuver instructions corresponding to all flight stages according to the flight sequence of an aircraft; performing target motion processing on the post-stall maneuver instruction according to a preset target motion model; and based on a preset track data conversion model, converting a result generated by target motion processing into a target post-stall maneuver track data. According to the invention, the flight data is converted and fitted through the target motion model and the flight path data conversion model; fitting of stealth aircraft over-stall maneuver can be realized; the method is simple, quick and easy to achieve, can be applied to the research on the Herbst over-stall maneuver of the stealth aircraft, solves the problems that the mathematical model is complex and the modelis difficult to establish by adopting the traditional fitting method, can make up the defects of the traditional method, and improves the rapidity of the fitting of the Herbst over-stall maneuver of the stealth aircraft.

Description

technical field [0001] The present invention relates to the technical field of aircraft trajectory fitting calculation, and more specifically, relates to a fitting method, system, computer equipment and readable medium suitable for stealth aircraft post-stall maneuvering. Background technique [0002] Post-stall maneuver, as a close combat tactical action, has become one of the important flight characteristics indicators of the fourth-generation fighters, especially stealth aircraft. The process is: the pilot pulls the lever to make the aircraft jump from the normal flight state at a high pitch rate to make a large angle of attack, so that it quickly reaches the stall angle of attack of 30° to 40°, and increases the angle of attack to 70° during the deceleration process. The pilot controls the aircraft Roll or yaw around the velocity vector so that the nose quickly points to the desired direction, then push the stick to reduce the angle of attack to exit the stall, turn to d...

Problems solved by technology

[0003] In order to solve the problem that when high-precision data is not needed, the six-degree-of-freedom equation of motion and the mathematical model of the thrust vector control system are complex, it is difficult to establish a simulation model, and it is not suitable for quickly obtaining stealth aircraft post-stall maneuver data. The fitting method, system, computer equipment and readable media for stealth aircraft post-stall maneuvering are simple, fast, and easy to implement in engineering, and can be applied to the research of stealth aircraft Herbst post-stall maneuvering, solving the problem of using traditional fitting methods. The problem of complex mathematical models and difficult model building can make up for the shortcomings of traditional methods and improve the speed of stealth aircraft post-stall maneuver fitting
