Abstract

In recent years, “Smart City” has been developing and need to obtain accurately information of the city, As a movable platform for sensing detection system in air, the ducted fan UAV will play an important role for information collecting in the complex urban environment. Because the complexity of traditional ducted fan UAV's control organ, which has strong air coupling, so there has big challenge if this kind of ducted fan UAV is used in the complex urban environment. A differential control type for ducted fan UAV has presented in this paper, through dynamics analysis and CFD simulation to the traditional ducted fan UAV and differential control type, the differential control type can keep the yaw stability of aircraft when the control flaps has a rational angle and stable lift when the control flaps become, meanwhile it can control the pitch and roll attitude through the differential motion of control flaps. So this differential control type is feasible and possesses some advantage over relative to traditional type if processing reasonable optimization and design.

一种导管式风机无人机微分控制类型的动力学分析与CFD计算

近年来，“智慧城市”不断发展，需要准确获取城市信息，作为空中传感探测系统的移动平台，导风无人机将在复杂的城市环境中发挥重要的信息采集作用。由于传统风管式无人机控制机构的复杂性，具有很强的空气耦合性，因此这种风管式无人机在复杂的城市环境中使用面临很大的挑战。本文提出了一种导管扇无人机的微分控制类型，通过对传统导管扇无人机和微分控制类型的动力学分析和CFD仿真，表明微分控制类型可以在控制襟翼角度合理时保持飞机的偏航稳定性，在控制襟翼变大时保持飞机的稳定升力，同时通过控制襟翼的微分运动来控制飞机的俯仰和滚转姿态。因此，如果进行合理的优化设计，这种差动控制方式是可行的，并且相对于传统控制方式具有一定的优势。
