Parametric Optimization and Analysis of the Preliminary Design of Small Jet UAV

以小型喷气无人机的总体方案研究为背景，建立了一种计算机辅助喷气无人机总体参数优化与分析程序系统。着重对适用于无人机的分析模块，如气动分析模块和重量分析模块的建立进行了较多的探索和尝试。为检验该优化分析系统的正确性，首先以意大利研制成功的喷气无人机（米拉奇－１００）为算例进行了验算和比较，然后对两种喷气无人机方案进行了总体参数优化计算，并对优化参数进行了敏感性分析。结果表明，所建立的喷气无人机总体设计参数优化与分析程序系统是可行的，所得结果合理、可信，对正在进行的喷气无人机总体方案研究有一定参考价值。

Using the preliminary design of a medium range, small jet UAV as the research background, a computer aided parametric optimization program suitable to the medium range, small jet UAV is developed. The main work of this dissertation is searching and trying to build some of the analysis modules, such as the aerodynamic analysis and weight analysis modules which are applicable to the computer aided parameter optimization program of the medium range, jet UAV. To check the validity of the computer aided parameter optimization program, a small jet UAV which is manufactured by Italy (Mirach 100) is analyzed and compared with the known resules. Then two of the medium range, small jet UAV design schemes are optimized, finelly the optimization parameter sensitivity analysis is done. The results show that the computer aided parametric optimization program constructed in this paper is feasible and reasonable. For the medium range, jet UAV preliminary design, the computer program is useful and helpful.
