飞机空中解体事故的残骸轨迹重建

本文采用高精度的数值解法－龙格－库塔法和二维分步优化计算方法，对飞机空中解体事故的残骸轨迹进行了分析研究，并复现了残骸的运动轨迹。为飞机事故调查单位分析事故原因提供了重要的线索和依据，同时给出模型机空中解体试验的计算结果，以证明这种方法是正确的、实用的。

TRAJECTORIES ANALYSIS ANALYSIS AND SIMULATION OF WRECKAGES FOR AN AIRCRAFT DISINTEGRATING

A special analysis and study of motion trajectories of wreckages for anaircraft disintegrating in flight by use of a high precision R K algorithm and two di-mensional step by step optimization algorithm is made to reappear the motion trajec-tories of the wreckages with the computer and to provide the important proof in examin-ing into the cause of the crash for the accident analysis department in this paper. Thecalculation of inflight disintegration for a model aircraft is presented and indicated thatthe method is very correct and feasible.
