摘要/Abstract

摘要：

为探究某型倾转四旋翼无人机（UAV，unmanned aerial vehicle）高速巡航过程中的气动变化规律，本文针对

所建立的倾转四旋翼无人机模型采用多重参考系（MRF，multiple reference frame）数值模拟方法开展分析。

通过改变机翼翼型相对厚度、旋翼总距和前飞速度等参数对无人机模型进行全机干扰模拟，并针对旋翼等

部件的气动变化特性进行分析。研究结果表明，在巡航过程中增加机翼翼型相对厚度会使后旋翼拉力系数

降低，当机翼翼型相对厚度增加 6% 时，拉力系数下降 17.09%。同时，在前进气流和前旋翼滑流的叠加影

响下，前旋翼滑流会对后旋翼气动性能造成一定程度的影响，并随着前飞速度增加，前旋翼滑流所产生的

影响呈先增强后减弱的趋势。

Abstract:

In order to explore the aerodynamic change law of a certain type of quad tilting rotor unmanned aerial vehicle (UAV)

during high-speed cruising process, the multiple reference frame (MRF) numerical simulation method is used to

analyze the quad tilting rotor UAV model established in this paper. By changing the relative thickness of the wing

airfoil, rotor collective pitch, forward flight speed and other parameters, the whole aircraft disturbance of the UAV

model is simulated, and the aerodynamic change characteristics of components such as rotors are analyzed. The results show that increasing the relative thickness of the wing airfoil can reduce the pull coefficient of rear rotor during cruise process, When the thickness increases by 6%, the tensile coefficient decreases by 17.09%. At the same

time, under the superposition of the front intake air flow and the front rotor slip flow, the front rotor slip flow will

have a certain impact on the rear rotor aerodynamic performance, and as the forward flight speed increases, the impact of the front rotor slip flow will first increase and then weaken.

Key words:

quad tilting rotor (QTR), aerodynamic disturbance of unmanned aerial vehicle, slip flow, propeller efficiency
