引射模拟器是一种经济方便的动力模拟试验装置,可以模拟排气影响并部分模拟进气影响,本文使用引射模拟器,研究了不同工况下翼吊发动机喷流对翼身组合体巡航、起飞、着陆等构型低速气动特性的影响。试验表明喷流对巡航构型带来升力损失,起飞构型升力影响较小,着陆构型升力增加较明显,所有构型都出现了阻力和低头力矩增量。
Launch simulator is a kind of economical and convenient dynamic simulation test device, which can simulate the influence of exhaust gas and partially simulate the intake effect. In this paper, the launch simulator is used to study the influence of wing jet engine ’ Cruise, takeoff, landing and other low-speed aerodynamic characteristics of the impact. Experiments show that the jet flow has a loss of lift on cruise configuration, a small lift on lift configuration, an obvious increase of lift on landing configuration, and resistance and bow torque increment in all configurations.
