摘要
燃油是飞机动态质量特性变化的主要影响因素,文中选取了基于液体相对平衡假设的油面角计算方法,给出了基于燃油三维模型切片分析与数据库技术的机载燃油及全机动态质量特性计算流程。在客户端服务器架构的基础上,设计一套与现有飞机质量特性数据管理系统相融合的体系结构,并利用CATIA二次开发技术,开发了一套集成化的燃油及全机动态质量特性分析工具,增强燃油三维模型的创建能力,提升全机动态质量特性的分析效率,通过了算例的测试与验证。
The fuel is the major factor influencing aircraft dynamical mass properties. This paper choose the fuel surface angle method based on relative equilibrium hypothesis,and give a computing procedure of airborne fuel and aircraft dynamical mass properties analysis based on three dimensional model slicing and database technology. Then,a solution fusing the aircraft mass properties data manage system is shown on the basis of C/S architecture,and a integrated program is developed to increase the ability on creating fuel model and improve the efficiency on analyzing. At last,the tool is tested and verified through designed examples.
