为实现飞机飞行历程实测数据的可视化,并检测飞行数据是否满足飞行大纲要求,运用OpenGL (Open Graphic Library)技术,研究了飞机的三维模型建模方法、特殊场景的生成技术和三维模型的实测数据驱动;建立了飞机的三维模型和飞行场景。基于飞行实测数据驱动方式,实现了飞机飞行历程数据的多视角可视化,直观地再现了飞机的实测飞行历程,并可以通过飞机飞行姿态判断飞机的受载状况,为判断实测飞行数据是否满足飞行大纲要求提供了可视化的评定方式。通过合理配置飞行实测数据格式描述文件和三维模型,该飞行数据可视化系统可实现不同机型实测数据的可视化,其具有较强的适用性。
To realize flight-test data visualization of aircraft’s flight course to solve the difficulty that whether the flight-test data meet the need of flight-test outline. Aircraft’s three-dimensional model and flight scene are generated by using open graphics library (OpenGL), modeling method of three-dimensional objects and it’s flight data driven method. The multi-view data visualization of flight course reappears from flight-test data. And according to the system, whether the flight-test data meet flight-test outline can be determined. The data visualization system provides an intuitive way to prove the validity of flight-test data and aircraft load state can be judged by the reproduced scene. The system could be applied to any type of aircraft as long as data description file and model configuration file are configured correctly.
