弹射模型(弹射模型滑翔机的简称)和手掷模型一样,本身没有动力装置。手掷模型是靠手掷的力量使模型升空;弹射模型则是靠橡筋的弹力将它弹到一定的高度,然后进入滑翔飞行。这种模型滑翔前进的“动力”是它自身重力的一个分力,这一点也是所有滑翔机的共同之处。 Ejection model (ejection model glider short) Like the hand-throw model, there is no power unit itself. The hand-throwing model is to lift the model by the power of throwing hands. The catapult model will pop it to a certain height by the elastic force of rubber band and then enter the gliding flight. Gliding this model “power ” is a component of its own gravity, which is all the glider’s commonality.
