Safe escape envelop predict method based on seat performance and attitude prediction

Based on aircraft attitude sensor information, a series of possible aircraft attitude combinations are obtained using the attitude-prediction algorithm based on fixed-step integration. Submit the data to the safe escape envelop model obtained by interpolation of the ejection seat performance parameters to evaluate the safety performance of the seat ejection in all possible predicted postures. If there is a possible posture that does not meet the ejection safety performance, the safe escape envelop predict is performed in the form of the remaining time from the unsafe ejection attitude. The method provides real-time prediction of safe escape before the attitude of the aircraft exceeds the escape envelop, so as to avoid the accidental ejection failure caused by the pilot's misjudgment of ejection timing.
