Abstract

The paper analyzes the problem of the operation of an unmanned aerial vehicle with ducted fan propulsors in hovering mode over a flat landing platform. Numerical calculations of gas dynamics were carried out using the traditional approach to turbulence simulation based on averaged Navier–Stokes equations and using the eddy-resolving method of large eddies. The results obtained which confirm a need to use eddy-resolving approaches.

涡旋求解法对带风管推进器无人机垂直着陆的数值模拟

摘要

本文分析了带有管道风扇推进器的无人驾驶飞机在平坦着陆平台上悬停模式下的运行问题。气体动力学的数值计算是使用基于平均Navier-Stokes方程的传统湍流模拟方法以及大涡旋的涡旋求解方法进行的。获得的结果证实了需要使用涡旋分辨方法。
