Abstract

A numerical simulation of the flow induced by rotation of the ducted fan blades of a quadcopter is carried out using the vortex-resolving approach that assumes solution of the full Navier–Stokes equations. Based on the numerical simulation results, the aerodynamic characteristics of the ducted fan are determined in various flight modes with asymmetric airflow over the surface swept by the propeller. In the problem formulation, various angles of the ducted fan rotation plane deviation from the vertical were considered for various flight modes of a multicopter type aircraft as well as characteristics of the non-perturbing incident air flow.

四轴飞行器涵道风扇周围气流的数值模拟及各种飞行模式下推力特性的确定

摘要

使用涡旋解析方法对由四轴飞行器的涵道风扇叶片旋转引起的流动进行数值模拟，该方法假设完整的 Navier-Stokes 方程解。基于数值模拟结果，确定了涵道风扇在螺旋桨掠过表面的非对称气流的各种飞行模式下的气动特性。在问题表述中，考虑了多旋翼飞机的各种飞行模式以及非扰动入射气流的特性，涵道风扇旋转平面偏离垂直方向的各种角度。
