Pressure probe for safety-arming device |
摘要 |
An air pressure sensing probe for providing static-dynamic differential air pressure to operate a guided missile warhead safety-arming device is disclosed. The probe assembly is hermetically sealed to keep the device free of dirt and moisture during storage. An electrically initiated squib, fired at a predetermined time after missile launch, supplies gas pressure to the base of the probe which acts as a piston. The probe breaks a tip seal, extends laterally out from the missile, and wedges into the erect position. The base of the probe contacts a sliding punch which severs seals from two air pressure conduits and aligns air passageways with static and dynamic pressure ports in the probe. Differential air pressure is thus fed to a safety-arming device which utilizes pneumatic operation.
