ABSTRACT:
Disclosed is a protection device for a radiation sensor in a vehicle such as a missile. The protection device comprises a cap mounted on the missile by opposed flanges having a seal therebetween to form a gastight space between the cap and the missile. An attaching device such as a pair of shear pins of unequal resistance is provided between the flanges so that pressurization of the space causes the shearing of first one and then the other of such shear pins so that the cap leaves the vehicle by moving with one component of movement in the direction of sensing and at least another component of movement perpendicular to that direction.
