Helicopters are very convenient for

Helicopters are very convenient for dropping freight by parachute, but this system has its problems. Somehow the landing impact has to be cushioned to give a soft landing. The movement to be absorbed depends on the weight and the speed at which the charge falls. Unfortunately most normal spring systems bounce the load as it lands, sometimes turning it over.

直升機是非常便於貨運下降的降落傘，但這一制度有它的問題。某種程度上著陸衝擊了一時半會還死給軟著陸。動作要吸收取決於重量和速度的電荷瀑布。不幸的最正常的春季系統反彈時它的負荷的土地，有時翻。

直升機是由降落傘下降運費很方便，但是這個系統有它的問題。不知怎的，著陸時的衝擊，必須墊著給軟著陸。要吸收的運動取決於所述的重量和在其中的電荷落入速度。不幸的是大多數普通彈簧系統反彈負載，因為它的土地，有時翻面。
