涡桨飞机发动机短舱气动改进设计研究
|
摘要
本文通过数值计算方法,从上下安装位置和局部外形两个方面着手改进短舱,给出两个改进方案,兼顾高速气动特性和低速气动特性两个方面,全面改善飞机气动特性,降低了短舱对机翼气动特性的不利影响,并且总结出短舱的安装位置和外形分别对机翼高低速气动特性的影响规律,为涡桨飞机翼吊短舱的气动设计提供有利经验。
In this paper, the nacelle position and configuration were optimized to improve the aerodynamic characteristics of the aircraft. Two different optimized nacelles are shown in the paper to indicate the nacelle aerodynamic impact to the wing. Meanwhile the aerodynamic characteristics of high speed and low-speed and mechanism of the wing-mounted engine nacelle were studied.
