Abstract

Shock sensitive equipment, for example, instruments in a spacecraft, must be protected against impacts, for example, those caused by severing explosions that separate the spacecraft from a used up rocket. For this purpose a platform carrying the component to be protected is secured to support structures of the craft by elastic spring devices, each of which has a low eigenfrequency or resonant frequency and a low damping constant, whereby the mounting is preferably so that friction forces are minimized. For example, the spring devices have a U-configuration connected to an L-configuration. Contact surface area minimizing ring spacers may be inserted between the platform and the spring devices.
