网络层次分析法在光电防护战斗效能评估中的应用

依据浮空器浮重平衡特性以及理想气体状态方程,探索了一种气体混充控制浮空器平飞高度的定高方式,并对浮空器气体混充定高技术进行了总体设计研究。考虑到热力学特性对于浮空器上升过程和平飞过程的重要性,结合工程热力学中混充气体的热物性能,以超压气球作为研究对象,分析球体上升和平飞过程中的热环境,并与动力学模型进行耦合。在此基础上,对混充气球上升及平飞过程进行力学仿真,得到气球上升过程中高度、速度、气体温度以及压强的变化,验证了浮空器混充定高技术的可行性,为后续浮空器飞行试验提供指导。

Application of analytic network process in evaluating the electro-optical protection combat effectiveness

Considering the deficiency of analytic hierarchy process in evaluation of electro-optical protection combat effectiveness, analytic network process was proposed to evaluate, toke analyze of the independence, correlation and feedback of the interior of the element hierarchy as entry point, putted forward the main index dictionary of electro-optical protection combat effectiveness, setted up the evaluation model, according to setting up the matrix, calculating, obtaining the weights, complete the evaluation. Validate the model by an example obtains evaluation results with high reliability, which provide theory-reference for evaluation of electro-optical protection combat effectiveness.
