核心机驱动风扇级可变弯度导叶的试验研究

摘要

为获得核心机驱动风扇级可变弯度导叶在实际流场中的气动性能,开展了有效的叶栅试验.将试验结果与计算结果进行对比,一方面验证了设计方法的可靠性,另一方面为可变弯度导叶的优化设计提供了详实的试验数据支撑.试验结果表明:核心机驱动风扇级可变弯度导叶设计方法可靠,气动性能满足设计要求,远优于不变弯度导叶的性能,与形状自适应叶型性能相当.%An effective cascade experiment is performed to illustrate aerodynamic performance of variable camber vanes in the core driven fan stage under the practical flow field.Then,it compares the test results with the calcu-lated results and verifies the reliability of the design method,provides the detailed test data support for the opti-mal design of variable camber vanes.Experimental results show that the design method of variable camber vanes in the core driven fan stage is reliable,the performance of variable camber vanes is well agreement with the de-sign result,the outperform is better than that the non-camber guide vanes,and similar with the shape-adap-tive airfoils.
