摘　　要：本文全面阐述了中国空气动力研究与发展中心(CARDC)直升机空气动力学研究的最新进展。围绕我国直升机空气动力学学科发展和旋翼飞行器自主创新研发需要,CARDC系统性地开展了直升机风洞试验平台建设,形成了先进的试验和数值计算技术,基本构建了涵盖常规、共轴和倾转构型的直升机空气动力学研究体系,发展了旋翼翼型优化设计与验证、旋翼桨叶表面脉动压力测量、旋翼噪声测量与辨识等新技术。以此为基础,建立了常规直升机全机气动干扰、全机气动噪声、旋翼和部件结冰,共轴刚性旋翼和倾转旋翼等新构型气动特性研究能力;未来5~10年,CARDC将重点推动基于特大型低速风洞的直升机全尺寸或大尺度旋翼气动与结构耦合动力学研究,以及综合风洞、计算和飞行三种手段的新概念旋翼飞行器关键技术验证。The latest progress of helicopter aerodynamics of China Aerodynamics Research and Development Center(CARDC)is comprehensively expounded in this paper.Focusing on the development of China’s helicopter aerodynamics discipline and the need for independent innovation of rotorcraft,CARDC has built a domestic first-class helicopter wind tunnel test platform,formed advanced test and numerical calculation technology,initially constructed covering conventional,coaxial and tilting structures,and developed new technologies such as airfoil optimization design and verification,rotor blade surface pulsation pressure measurement,and rotor noise measurement and identification.Based on the works above,CARDC have established the research capabilities of conventional helicopter such as aerodynamic interference,aerodynamic noise of the entire aircraft,icing of rotors and components,and aerodynamic characteristics of new configurations such as coaxial rigid rotors and tilting rotors;in the next five to ten years,CARDC will focus on promoting the research on helicopter full-scale or large-scale rotor aerodynamics and structural coupling dynamics based on super-large low-speed wind tunnels,and the verification of key technologies of new concept rotorcraft that integrates wind tunnels,calculations and flight.
