1.4 Use MATLAB software to simulate all lightning wave lightning wave cut off in tail and lightning wave cut off in the head. Firstly, FFT decompose these waves into multiple harmonic waves; then according to the amplitude to take out of larger harmonic wave.
4、用MATLAB仿真软件对雷电冲击全波、波尾截断雷电冲击波和波前截断雷电冲击波进行了仿真，用快速傅立叶变换FFT将其分解为多次谐波，并采用幅值阀值法提取出幅值较大的谐波。收藏指正
2.Aerodynamic heating of the protuberances,such as the leading edge of tail fins and the air deflector,is calculated by using plane?oblique shock wave theory,the conical flow theory,Prandtl?Meyer expansion flow theory and the aerodynamic heating theory. Comparison of the calculated results with tested results shows that the heat?protection design is effective.
采用平面斜激波理论、锥形流动理论、普朗特 迈耶膨胀流动理论和有关气动加热的理论方法,对TY 3探空火箭的尾翼前缘、气流导流块两突起物处的气动加热情况进行计算,计算结果与飞行实验结果作了比较,证明所采取的防热设计是有效的。收藏指正
