Design Of The Dynamic Components Of Light QTR Aircraft

The QTR aircraft designed in this paper is a new type of high speed aircraft which combines the helicopter with the fixed-wing aircraft.It has the characteristics of vertical take-off and landing as helicopter and can fly as fast as a fixed-wing aircraft.A set of design scheme for the dynamic components of a 60 kg stage light QTR aircraft is proposed in this paper,including rotor,power transmission mechanism and tilting mechanism.The following research work is carried out in this paper.First of all,the design requirements of each dynamic component are analyzed according to the requirements of the aircraft technical features,and then the detailed design is carried out on the basis of these requirements.Secondly,through the calculation and simulation analysis,the relationship between the rotor pulling force,the required power and the collective pitch,and the design scheme of rotor and power transmission mechanism are obtained.According to the requirements and design scheme of the nacelle,select a suitable set of tilting mechanism design scheme,and improve continuously to get the best design.Then,the fifth chapter carries out the research and development of prototype.In this process,the machining errors of each component are considered to provide convenience for later assembly.After the completion of assembly,the components will be debugged.Finally,this paper carries out lift test of rotors and ground tests on the prototype,the performance verification of the prototype shows that the design can fit the request.In this paper,the design of the dynamic components of the QTR aircraft is mainly studied,and the prototype is developed and tested.The rationality and feasibility of the scheme are verified,which will lay a foundation for the later research.
