摘要
螺旋桨噪声不仅会对机场等起降环境造成噪声污染,而且严重影响机舱内乘员舒适度,开展低噪声螺旋桨设计方法研究对于先进涡桨飞机研制具有重要意义。本文在某螺旋桨构型的基础上,针对桨尖部分进行气动外形的设计,以期在保证螺旋桨气动特性的同时,改善其噪声特性。采用遗传算法和kriging代理模型结合的方法进行了螺旋桨桨尖降噪优化,其中,气动和噪声特性分别通过CFD/FW-H混合方法计算得到,设计变量包括弦长、扭转角,后掠角沿径向分布。相比基础桨叶,优化设计所得构型的气动噪声特性得到一定程度的改善。针对基准桨和优化桨构型,在FL-9风洞声学试验段内进行了螺旋桨气动噪声试验测量,对降噪设计结果进行了验证。
An efficient and low noise propeller will be very important in advanced propeller airplane research.In order to reduce the noise of propeller by changing the geometry of blade tip, an study on aerodynamic/acoustic optimization design is made based on a high efficient optimization tool with genetic algorithm and Surrogate model.The characteristic of aerodynamic and acoustic are calculated by CFD/Ffowcs williams-Hawkings method.The distributions of chord length, twist angle and sweep angle are parameterized as design variables in the optimization process.Optimum blade shows an improvement in acoustic and aerodynamic characteristic.In order to verify the optimization result, an aero-acoustic test of propeller in FL-9 wind tunnel carried out.
