ABSTRACT:
An attachable, ablating shield comprises a metalized sheath for fitting closely over, for covering, and for protecting an electronics section in a missile from external electromagnetic radiation, particularly from high-energy radio frequency radiation, during launch. The sheath has weakened seams so that the sheath will separate from the missile when a seam is split. The sheath splitting system comprises an explosive device located near a seam, a detector for sensing the firing of the rocket motor, and a transfer line therebetween for receiving a motor-fire signal from the detector and for transferring a corresponding signal to the explosive device to split the sheath. A preferred embodiment employs a low-explosive and a transfer line that is a high-intensity shock pulse tube. The transfer line ablates with the sheath.
