Design of Aircraft Flight-Mission-Adaptability Evaluation System Architecture

针对目前缺乏有效的试验手段和试验方法来评价多要素约束下飞行器的适应性评估问题,利用建模仿真的方法设计实现了飞行器飞行任务适应性评估系统,介绍了整个系统架构组成,利用该系统可综合航迹、控制、气动、结构、防隔热等多个要素,根据飞行器飞行流程及技术约束,建立多要素的适应性准则,围绕特定的规划航迹,基于实际的飞行器系统模型,考虑多种偏差因素,进行飞行全过程多要素数字仿真,评估特定飞行任务的可行性,可以为飞行任务筹划和飞行器主要指标评估提供有效的数据支持。

The paper introduces the simulation modeling method and architecture of aircraft flight-mission-adapt- ability evaluation system which is aiming to evaluate the aircraft adaptability problem with multi-element constrains in defect of effective test instrumentality and test method. In the system, a multi-element principle was created based on the aircraft＇ s flight process and technical constrains, considering the elements including trajectory, control, aerody- namic, structure and thermal. In this system, multi-element simulation base on real flight vehicle system model and specific planned trajectory can be realized to evaluate the feasibility of specific flight mission and support the mission vlanning and Drincival performance evaluation of aircraft.
