摘要
研究OWN(Over-the-Wing Nacelle)对机翼升力特性的影响。通过对OWN和机翼组合体的气动数值模拟,给出环量(升力)沿机翼展向分布,结合机翼剖面上下翼面压强分布,分析了OWN对机翼的影响;通过对比研究分析了OWN的不同安装位置对机翼升力特性的影响。研究结果表明,可以作为类似的发动机短舱置于机翼上方布局设计参考。
The effect of OWN ( Over-the-Wing Nacelle) upon lift charateristics of the wing were investigated. The effect of Over-the-Wing Nacelle on the wing was studied based on the spanwise distribution of circulation( or Lift) together with upper and lower section pressure distribution on the wing,both of which were abstracted from pneumatic numerical simulation. The influence on lift charateristics of the wing,which was brought by different installation location of the OWN,was analysed through comparative study.
