摘要:

基于虚拟飞行的大型客机特性评估,需要更加精准的燃油重量特性,而现有的燃油重量特性分析方法在计算速度和精度上已经无法满足需求,也没有系统的燃油重量特性仿真工具。针对这一问题,改进传统燃油切片法,提出一种基于数据库和耗油顺序的分析方法,分为油箱燃油重量特性数据库构建、燃油系统瞬时重量特性计算和燃油系统重量特性实时监控3个模块进行研究,并基于CATIA二次开发平台,VC++开发环境和Unity3D游戏引擎,开发了一套较系统的飞机燃油重量特性分析软件。选用双通道的A330-300客机作为算例,根据官方公布的数据,利用CATIA建立油箱组模型,作为仿真的原始输入,经过前处理、仿真和后处理3个步骤,对算法及软件的快速性和准确性进行了验证,也说明了发展燃油主动重心控制技术的必要性。

Abstract:

More accurate information of fuel weight properties is needed in virtual flight based evaluation of large civil aircraft properties; however, the existing method for analyzing fuel weight properties has been unable to meet the demands in computing speed and accuracy, and there is not a systemic and proven simulation tool to analyze fuel weight properties. To solve these problems, we improve the traditional slice method, and propose an analytical method based on database and fuel consumption order. The method is divided into three modules: construction of the database of the tank fuel weight properties, calculation of the instant weight properties, and real-time monitoring of the weight properties. Based on CATIA secondary development, VC++ development environment and the Unity3D game engine,a systemic software for analyzing aircraft fuel weight properties is developed. The two-channel A330-300 aircraft is selected as an example. According to the published official data, CATIA is used to establish the tank group model as the input of the simulation. Based on pre-processing data preparation, simulation and post-processing analysis, the rapidity and accuracy of the method and software are verified. The necessity of developing the technique for actively controlling the fuel center of gravity is also discussed.

Key words: aircraft, fuel weight properties, slice method, database, fuel consumption order
