摘　　要：倾转旋翼飞机的主要噪声来源于螺旋桨,而噪声对飞行员工效具有非常大的影响。在分析噪声对飞行员工效影响的基础上,使用计算流体力学(computational fluid dynamics,CFD)方法对优化设计的旋翼螺旋桨流场进行计算分析。通过数值计算得到旋翼螺旋桨的拉力特性、功率特性等气动性能参数。螺旋桨的拉力系数C_T、功率系数C_P都随着进速比J的增大而减小,螺旋桨的推进效率随着进速比的增大,先增大后减小,在设计点附近,螺旋桨推进效率达到0.87以上。采用Lowson方法对螺旋桨的辐射噪声进行初步分析,随着螺旋桨转速的提高,各方位总声压级指向性一致,并有所提高。The main noise of tilt-rotor aircraft comes from the propeller, and the noise has a great impact on the efficiency of pilots. Based on the analysis of the noise effect to the pilots, the flow field of the designed rotor propeller was analyzed by the computational fluid dynamics(CFD) method. The aerodynamic performance parameters of the rotor propeller, such as the thrust and power performances, were obtained by numerical calculation. Both the thrust coefficient C_T and power coefficient C_P of the propeller decreased with the increase of the advance ratio J. The propeller’s propulsion efficiency increased firstly and then decreased with the increase of the advance ratio J, and its propulsion efficiency reached above 0.87 around the design point. Lowson method was used to analyze the radiated noise of the propeller. With the increase of the rotating speed of the propeller, the directivity of the total sound pressure level in all directions was consistent and improved.
