飞行器力学环境参数分布特性及飞行散差研究进展

A review of distribution and flight-to-flight variability of vehicles' dynamic environment parameters

因各方对飞行器力学环境散布特性、散差量级等的认知和理解存在较大差异,相关标准的规定也不一致,故在实际使用过程中存在较大歧异。文章搜集整理了大量关于飞行力学环境方面的国内外文献资料,论述散布特点、统计分析方法以及飞行散差等的研究历史及现状,提出了设计过程中的应对措施以及后续研究建议,为环境条件的精细化设计以及产品的可靠性分析提供参考。

While the description and the regulations of the dynamic environments of flying vehicles see differentinterpretations in papers and the relevant standards are not quite consistent, considerable misconceptions are found inpractical engineering. A number of domestic and foreign literature and standards are reviewed in this paper, focusing onthe development history and research situation. Relevant recommendations are made on the formulation and theanalysis of flight dynamic environments, to provide guidance for the precise design of environmental conditions andproduct reliability analysis.
