That can be sustained against the induced drag of forward flight without significant loss in to vertical lift out puts to support the weight of the aircraft.
这可以持续反对前飞诱导阻力，在没有重大损失摆脱垂直放在支持飞机的重量。

By doing integral computation on the wake surface that is down from the aircraft and vertical to the velocity of far field, it can get the lift, induced drag, wave drag and the total drag.
在飞行器所在流场的下游一垂直于来流速度的截面上进行积分计算，得到升力、诱导阻力、激波阻力和总阻力。

The spanwise distribution of lift for minimum induced drag of wings having a given lift and a given bending moment.
