探空火箭风场补偿及等效弹道风转化

The Wind Compensation of Ballistic Trace of a Low Altitude Sounding Rocket with the Translation Model from Variable Wind to Constant Wind

介绍一种以计算机变步长迭代搜索替代以往的查表算法来获得风场中火箭补偿参数的方法 ,避免了采用近似理论造成的误差 ,以及复杂的造表过程 ,提高实际工程中的处理速度与自动化程度 ,而且精度比原风权法要高。此外 ,本文还提出一种新的弹道风生成方法。在等效程度上 。

An automatically iterative method to get optimal wind compensation launching configurations of the sounding rocket is proposed. The method avoids error of applying approximative theory and accelerates convergence by using adapt step search. In addition, a new method to translate from variable wind to constant wind is also presented. The variable wind and result constant wind are equal in effect on trace of rocket .The more satisfactory results by two methods are shown.
