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。

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.

这个合升力的水平分力就是诱导阻力。

The aft component of this lift vector is the induced drag.

联结翼布局与常规布局相比具有结构重量轻、诱导阻力小、升力系数大和稳定性良好的特点。

The joined-wing configuration, as compared with the normal configuration, is characterized by low structural weight, small induced drag, big lift coefficient and good stability.
