PD-77264 AUTOMATIC BLAST ACTUATED POSITIVE Michael L. Leigh RELEASE MYSSILE DETENT Richard D. Stubbs A missile or rocket detent and positive release mechanism actuated by the rocket's thrustor. The mechanism is mounted on the outside of a rocket launcher tube and the notched-end of a spring-loaded lever extends into the launch tube for positively locking a rocket into place. The lever has a centrally located pivot point and a cam at the other end. One end of a sear is connected to a second lever which extends into the rocket's blast region. The other end of the sear has a cam actuating surface which is disposed against the first lever's cam. The blast from the rocket's thrustor pushes the second lever around on its pivot point such that the sear actuates the cam-end of the first lever, rotating it a small distance on its pivot point thereby withdrawing its notched-end and releasing the rocket.
