    • A powder pod is releasably coupled with a model aircraft, such as a model glider plane, to initially power the aircraft into flight and to thereafter separate from the aircraft under the influence of gravity. In the preferred embodiments of the invention, an adaptor element is affixed to the underside of the model aircraft fuselage, and the power pod itself is releasably coupled with the adaptor. The releasable coupling of the power pod with the adaptor is structured such that the power pod remains coupled with the adaptor to thereby power the model aircraft into flight as long as the power pod is providing a forward thrust. In one embodiment, the power pod separates from the adaptor when operation of the power pod ceases; in another embodiment, the power pod remains coupled with the adaptor after operation of the power pod ceases with the pod separating from the adaptor upon command of a remote control radio signal. Upon separation of the power pod from the adaptor, a parachute stored within the pod is deployed by means of a rip cord connected at one end to the model aircraft. The rip cord includes a replaceable, breakable link which breaks as the pod and the deployed parachute fall away from the model aircraft. The power pod includes an adjustable engine mounting plate for permitting the angle of thrust to be established at optimum inclination. The adaptor includes a layer of deformable, resilient material which permits the adaptor to mount without modification to different fuselage configurations. The parachute is attached to the power pod in such a way that the power pod lands in an orientation which minimizes any risk of damage to the pod upon impact with the ground.
    • 粉盒可以与诸如模型滑翔机之类的模型飞机可释放地联接起来,以使飞机起飞使其飞行,然后在重力作用下与飞行器分离。 在本发明的优选实施例中,适配器元件固定到模型飞行器机身的下侧,并且动力箱本身可释放地与适配器联接。 动力舱与适配器的可释放的联接被构造成使得动力舱与适配器保持联接,从而只要动力舱提供向前的推力,模型飞机就能飞行。 在一个实施例中,当功率盒的操作停止时,电源盒与适配器分离; 在另一个实施例中,根据遥控无线电信号的命令,在功率盒的操作之后,电源盒保持与适配器耦合。 在将动力舱与适配器分离时,存储在舱内的降落伞通过在一端连接到模型飞机的裂缝部署。 裂缝包括一个可更换的,易断裂的环节,随着荚和部署的降落伞远离模型飞机而破裂。 动力箱包括可调节的发动机安装板,用于允许以最佳倾角建立推力角。 适配器包括可变形的弹性材料层,其允许适配器安装而不改变到不同的机身配置。 降落伞以这样的方式附接到动力舱,使得动力舱降落到使得在与地面碰撞时损坏舱架的任何风险最小化的方向上。
