An Algorithm for Aircraft Tailstrike Screening Based on Geometric Constraint Model

A tailstrike mainly occurs during takeoff or landing, which will cause certain or significant structural damage to the aircraft and endanger flight safety. It is very important to screen and target the flight of aircraft tailstrike for business aircraft operational safety. In this paper, the critical parameters of aircraft tailstrike modeling are determined according to the geometry characteristics of each aircraft type, the geometric boundary equation of aircraft tailstrike for takeoff and landing is constructed respectively, and the geometric constraint model is established. The data extraction module of historical flights and the flight screening module of tailstrike are used to screen the most risky flight from all extracted flights quickly and accurately. The result shows that the proposed method can precisely target the flight of tailstrike, especially suitable for screening and locking of flight with slight tailstrike. The feasibility and practicability of the proposed algorithm are verified.
