摘　　要：复合式常规旋翼高速直升机是国内外高速直升机重点发展的几种构型之一。本文首先简要介绍了某300kg复合式常规旋翼高速直升机的机身气动布局形式,针对该机设计并加工了1∶1.5机身风洞试验模型,在4m×3m风洞开展了机身气动特性风洞试验。通过对比不同机身部件组合状态在不同迎角、侧滑角条件下的气动力及纵横向气动导数,获得了全机及各部件气动性能。根据风洞试验结果,结合已建立的旋翼气动力模型和螺旋桨气动力模型,建立了全机飞行力学模型,并分析了不同飞行速度下全机的静稳定性,验证了该复合式高速直升机具有合理的机身气动布局,研究结果可为复合式常规旋翼高速直升机的进一步发展提供参考。Hybrid high-speed helicopter is one of developed configurations of high-speed helicopter.In this paper,the fuselage aerodynamic configuration of the 300kg hybrid high-speed helicopter was introduced firstly.The 1:1.5 wind tunnel test model of fuselage was designed and manufactured,and the wind tunnel test of aerodynamic characteristics of fuselage was carried out in 4m×3m wind tunnel.By comparing the aerodynamic force and aerodynamic derivatives of different fuselage conditions under different angles of attack and sideslip angles,the aerodynamic performance of the whole fuselage and its parts is obtained.According to the wind tunnel test results,combined with the rotor aerodynamic model and propeller aerodynamic model,the flight mechanics model of the whole aircraft was established and the static stability of the whole helicopter at different flight speeds was analyzed.The rationality of fuselage aerodynamic configuration of the hybrid high-speed helicopter is verified.The research results can provide reference for the further development of hybrid high-speed helicopter with single main rotor.
