    • An airborne platform comprising: (a) an aerodynamic body; (b) a protected element within the aerodynamic body; and (c) a cover, reversibly secured to the aerodynamic body, for protecting the protected element from an external atmosphere. The present invention is particularly suited for an electro-optical detection system equipped with an optical dome or window. Optical windows carried on airborne platforms are known to be particularly sensitive to the high temperatures generated by air friction at super-sonic speeds. By covering such a window when the airborne platform is in flight, and releasing the cover just before use, the electro-optical detection system equipped with the optical window can be made operative, even at airborne platform speeds of several Mach and higher.
    • 一种机载平台,包括:(a)空气动力学体; (b)空气动力学体内的受保护元件; 和(c)可逆地固定到空气动力体上的盖,用于保护受保护的元件免受外部气氛的影响。 本发明特别适用于配有光学圆顶罩或窗户的电光检测系统。 已知在机载平台上携带的光学窗对于在超声速度下的空气摩擦产生的高温特别敏感。 通过在机载平台飞行时覆盖这样的窗口,并且在使用之前释放盖子,即使在几马赫甚至更高的机载平台速度下,配备有光学窗口的电光检测系统也可以工作。
