摘要
先进的气动设计是提高飞机飞行性能、增强竞争力的重要因素,其设计策略也经历了由单纯气动优化到多学科综合优化、从单一设计点优化到广域度多点优化等变化过程。近年来,针对设计点的优化再次成为重点.并利用先进的飞行控制、机载系统等对非设计状态进行补偿,既提高了设计点的气动效率、又不会带来非设计点的气动损失。本文以波音空客等公司当前型号为例,对这种机翼气动设计策略变化的机理进行研究,并发现了其通过短舱气动干扰来控制激波演化过程、从而降低设计点波阻的方法。
The aerodynamic design is a key feature for improvement of performance and competitiveness for civil airplanes.The strategies have been changed in the past years,i.e.aerodynamics optimization to mullidisciplinary optimization,or single point optimization to multi-points optimization.Recently,the strategies came back into design point optimization again,with the aid of new technologies such as flight control,airborne systems etc.The new strategy can improve the aerodynamic efficiency at design point,while remains the performance at other off-design status.In this paper,we studied this aerodynamic strategy using new airplanes from Boeing or Airbus,as well as the mechanism of wave drag suspending by nacelle interference and shock wave control on the wing.
