A no-load missile restraint arrangement for releasing a rocket propelled missile promptly after ignition of its rocket motor, and the expulsion of a nozzle seal from its rocket motor nozzle. An anchor device extends from the aft end of the missile, which is engaged by the nose portion of a pivotable latch member. The latch member has two operative positions, with the nose portion engaging the anchor device until the seal is driven rearwardly at the time of ignition of the rocket motor. An elongate device operatively associated with the latch member is struck by the rapidly moving seal, bringing about the releasing of the latch member such that it can pivot to an anchor-releasing position. In this way the missile is released prior to any substantial buildup of thrust in the rocket motor.

1. A springless, no-load missile restraint arrangement involving substantially no compromise of the aerodynamic configuration of a missile, said restraint arrangement releasing a rocket propelled missile from its canister promptly after ignition of its rocket motor, and the expulsion of a nozzle seal from its rocket motor nozzle, said restraint arrangement comprising an elongate anchor means of small diameter extending from the aft end of the missile, a base member mounted on the interior of said canister adjacent the aft end of the missile and supporting a pivotable member, said pivotable member having an anchor-engaging position, and an anchor-releasing position, trigger means operatively associated with said pivotable member, and extending into a position adjacent the nozzle seal, said trigger means, when struck by the seal shortly after motor ignition, deforming to permit a pivoting movement of said pivotable member into its anchor-releasing position, such that the missile can sever any restraints to the canister before substantial buildup of thrust in the rocket motor. 2. A springless, no-load missile restraint arrangement involving substantially no compromise of the aerodynamic configuration of a missile, said restraint arrangement releasing a rocket propelled missile from its canister promptly after ignition of its rocket motor, and the expulsion of a nozzle seal from its rocket motor nozzle, said restraint arrangement comprising an elongate anchor means of small diameter extending from the aft end of the missile, a base member mounted on the interior of the canister adjacent the aft end of the missile and supporting a pivotable member, said pivotable member having an anchor-engaging position, and an anchor-releasing position, an elongate trigger member attached to said base member and to said pivotable member, and extending into a position adjacent the nozzle seal, said trigger member, when struck by the seal shortly after motor ignition, deforming to permit a movement of said pivotable member into its anchor-releasing position, such that the missile can sever any restraints to the canister before substantial buildup of thrust in the rocket motor. 3. A springless, no-load missile restraint arrangement involving substantially no compromise of the aerodynamic configuration of the missile, for releasing a rocket propelled missile from its canister promptly after ignition of its rocket motor, and the expulsion of a nozzle seal from its rocket motor nozzle, said release arrangement comprising an elongate anchor means of small diameter secured to the aft end of the missile, to which releasable restraint means are attached, said restraint means comprising a base member mounted in an aft portion of the canister, adjacent the aft end of the missile, a pivotable member supported upon said base member, and having first and second positions, said pivotable member having a nose portion arranged, when the pivotable member is in its first position, to engage said elongate anchor member, said pivotable member moving to its second position, to bring about the release of the anchor member, upon expulsion of the seal from the nozzle of the rocket motor, and the seal striking a deformable component operatively associated with said pivotable member. 4. The springless, non-load missile restraint arrangement as recited in claim 3 in which an elongate member is supported by said base member at a location adjacent said pivotable member, with said elongate member and said pivotable member being interconnected, said elongate member extending approximately to the centerline of the motor nozzle, so as to be in the path of the seal at the time it is expelled from the nozzle by the initial buildup of pressure in the rocket motor, said elongate member, upon being struck by the seal, deforming to release the pivotable member, so that it can pivot into its second position, thus to release the anchor member before any substantial buildup of thrust in the rocket motor. 5. The springless missile restraint arrangement as recited in claim 4 wherein said anchor member is an eyebolt. 6. The springless, no-load missile restraint arrangement as recited in claim 4 wherein said elongate member is vertically adjustable with respect to said pivotable member, so as to enable at the time of installation, the removal of undesirable slack between said elongate anchor means and said nose portion.
