摘要
首先对飞行器间歇滑翔飞行所需要的两种上升气流的产生形式及条件进行了分析,利用气象和地形、地貌信息对热力上升气流进行了数值模拟;其次基于椭球绕流方法,建立了动力上升气流的工程化模型,最后经过数学仿真验证了模型的有效性。
Through analysis of modality and conditions of two kinds of ascending airflows needed in intermittent gliding flight, the thermodynamic ascending airflow is numerically simulated with terrain, physiognomy and meteorological informations, and an engineering model of dynamic ascending airflow is set up based on the theory of flow around ellipsoid. Simulation result shows the effectiveness of this model.
