【摘要】：近年来,无人机在军用和民用领域中受到越来越广泛的应用。由于具有可垂直起降、定点悬停、低空低速性好等优点,涵道旋翼无人飞行器成为应用最广泛的无人机之一。本文研究目的是设计复合式涵道共轴双旋翼无人飞行器试验平台。根据飞行器设计要求,进行飞行器总体结构设计,阐述了旋翼系统、动力传动系统、主体梁架以及机身外形结构等设计要求和细节。针对共轴双旋翼飞行器结构要求,提出了上下旋翼对扣的设计思想。上下旋翼分别由相互独立的动力机构驱动,采用同步齿形带动力传动方式,简化了动力传动机构设计。分析计算了旋翼系统动力需求,并通过电动机驱动旋翼系统进行试验验证,据此确定发动机选型。通过对飞行器的结构受力情况进行分析,设计了十字形梁架和前三点式起落架结构。飞行器机身外形采用翼身融合形式设计,中间嵌有涵道共轴双旋翼系统。机身外形采用分块结构设计制作,在确保结构强度的同时方便飞行器安装、调试、测试和运输。依据飞行器飞行性能要求,对飞行器航电飞控系统进行配置设计。通过进行发动机功率、旋翼气动升力以及飞行器地面系留测试试验,对涵道共轴双旋翼飞行器的气动特性进行了分析研究,确定了发动机选型、旋翼桨叶结构参数以及气动布局设计,为飞行器设计研制提供实践依据。通过本文的研究工作,完成了复合式涵道共轴双旋翼无人飞行器总体设计,并验证了设计方案是可行、有效、可靠的。
[Abstract]:In recent years, UAV has been more and more widely used in military and civil fields. It has the advantages of vertical take-off and landing, fixed point hovering, low altitude and low speed, and so on. Culvert rotor unmanned aerial vehicle (UAV) has become one of the most widely used unmanned aerial vehicles (UAVs). The purpose of this study is to design a composite culvert coaxial dual rotor UAV test platform. The design requirements and details of rotor system, power transmission system, main beam frame and fuselage shape structure are described. The design idea of the upper and lower rotor is put forward. The upper and lower rotor is driven by independent power mechanism, and the synchronous gear belt is used to drive the upper and lower rotor. The design of power transmission mechanism is simplified. The dynamic requirements of rotor system are analyzed and calculated, and tested by the motor driven rotor system. According to this, the selection of engine is determined. The cross beam frame and the front three point landing gear structure are designed through the analysis of the structure of the aircraft. The fuselage of the aircraft is designed in the form of wing body fusion. The fuselage is designed and manufactured by block structure, which ensures the strength of the structure and facilitates the installation, debugging, testing and transportation of the aircraft, according to the flight performance requirements of the aircraft. The configuration and design of aircraft avionics flight control system were carried out. The engine power, rotor aerodynamic lift and aircraft ground retention test were carried out. The aerodynamic characteristics of culvert coaxial dual rotor aircraft are analyzed and studied. The engine selection, rotor blade structure parameters and aerodynamic layout design are determined. Through the research work in this paper, the overall design of compound culvert coaxial double rotor unmanned aerial vehicle is completed, and the design scheme is proved to be feasible, effective and reliable.
