Abstract: A mechanism is described for deploying a shield from a space vehicle or the like. Such a shield may be employed for minimizing radar echo, for protecting the vehicle from solar radiation, or for providing a bumper for minimizing damage from micrometeoroids. A spring loaded mechanism is provided so that the shield can be folded into a compact package for launch of the space vehicle. The spring loaded mechanism further provides for rapid development of the shield when restraints are released. Arrangements are provided for deploying semi-cylindrical shields and quarter spherical shields.
