空中加受油仿真中尾流扰动的建模与仿真

对现代军机空中加受油仿真中的加油机尾流仿真进行了研究,论述了加油机尾流的组成流场、形成原因和对受油机的扰动作用。根据飞行试验数据资料和缜密的理论推导,将加油机尾流对受油机的扰动作用分为纵向和横向两个通道,并分别建立了空中加受油仿真的尾流扰动仿真模型,并给出了在实际工程应用中的调试方法。建立的加油机尾流扰动仿真模型在某型飞机飞行仿真系统应用中收到了很好的效果。

Model and Simulation of Wake Interference in Air-to-air Refueling Flight Simulation

The simulation model of wake in air-to-air refueling flight simulation was studied.Causes of composition vortex and their actions to a refueled aircraft were discussed.Based on credible flight test data and careful theoretical deducing and analyzing,the model of the wake interference in air-to-air refueling flight simulation was divided into two parts,longitudinal interference and lateral interference,and their simulation models were built respectively.Furthermore,the method of adjusting models was offered.The models were applied in a flight simulation system of a fighter successfully.
