倾转四旋翼机高效低噪旋翼外形优化设计
Optimization design of high-efficiency and low-noise rotor layout for quad-tiltrotor aircraft
摘要
Abstract
Quad-tiltrotor aircraft experience complex unsteady noise characteristics due to the presence of multi-vortex and multi-component aerodynamic interference among various components during typical flight modes.To obtain the high-efficiency and low-noise rotor shape combined with helicopter mode and fixed-wing mode,the computation meth-ods of rotor aerodynamic and noise considering the aerodynamic environment of the whole aircraft are established.The sensitivity analysis of the tip shape parameters to the aerodynamic and noise characteristics of the rotor is carried out.Based on the improved Latin hypercube sampling method and the genetic algorithm,the high-efficiency/low-noise shape design optimization process of the forward and rear rotors is established.A set of high-efficiency and low-noise forward and rear rotor shapes are obtained and are further compared with the reference ones.The results show that the aerodynamic and noise characteristics of the rotor are sensitive to the blade tip shape,which can severely affect the hover efficiency and cruise efficiency.After optimization,the hover efficiencies of the forward rotor and the rear ro-tor are increased by 1.5%and 1.0%,and the noise pressure level is reduced by 1.8 dB.In the fixed-wing mode,the cruise efficiencies of the forward rotor and the rear rotor are increased by 10.1%and 9.0%,and the noise pres-sure level is reduced by 2.2 dB.关键词
