| 摘要 | A mechanism for driving a striker means and igniting a missile second motor responsive to acceleration forces. The acceleration forces act on a first latching means to unlatch a rotor assembly which operates a time delay mechanical movement connected to the rotor. Operation of the time delay mechanical movement releases a second latching means, and force moving means of the second latching means provides the power to drive the striker means against the second motor igniter. | ||||||
| 权利要求 | 1. In a missile having a pair of rocket motors, a mechanism comprising: a support, an inertial device disposed for rearward movement to engage the second of said motors for percussive ignition thereof responsive to a predetermined value of acceleration of said missile; said inertial device being rotatably disposed in said support for delay of the ignition responsive to the predetermined value; latching means to secure said inertial means to said support and to release said inertial means responsive to the predetermined value; a rotor housing mounted in said support; a rotor assembly rotatably disposed In said housing and provided with a weight; said latching means disposed to secure said assembly and said weight in inoperative position, and to unlatch said assembly for rearward and rotational movement responsive to the predetermined acceleration force; time delay means connected to said assembly, and actuated by inertia thereof responsive to the unlatching to release a second latching means; and striker means for igniting said second motor responsive to the release. 2. A mechanism as defined in claim 1 wherein said rotor assembly includes a rotor having a cavity a weight located in said cavity and provided with a chamber, and a retainer for securing said weight in said cavity. 3. A mechanism as defined in claim 2 wherein said first latching means includes a spring located in said chamber for cooperation with said weight to retain the weight in latched position until the acceleration reaches the predetermined value. 4. A mechanism as defined in claim 3 wherein said time delay means includes a nut and provided with internal helix convolutions, a shaft disposed for cooperation with a plate assembly and said convolutions to provide rotation and rearward movement of said rotor assembly; a stop member mounted on the end of said shaft for subsequent rotation of said shaft with said rotor responsive to rotational inertia of said rotor assembly; a pin disposed for engagement between said rotor assembly and said plate assembly and for release therefrom for the rotation responsive to the forward movement, and said shaft being disposed for threaded engagement with said plate assembly and for release therefrom responsive to the subsequent rotation. 5. A mechanism as defined in claim 4 wherein said rotor housing is provided with a pair of diametric holes and said second latching means includes a pair of pins and a slide disposed on said shaft for rotation therewith to retain said pins in said holes and in engagement with said support to secure said housing thereto, said support and said pins having surfaces therebetween for slidable operation of said pins to release said rotor housing responsive to rotation of said shaft. |
