Abstract

Abstract A control mechanism is provided for tripping a system in a releasable missile. The control transmission which controls tripping of the system comprises an energy store held under stress by a locking member. The locking member is designed to be actuated on completion of unwinding of the storage pulley thereby to release the energy store and so initiate tripping of the system connected to it. The invention has a particular application in releasable missiles such as bombs which are transported by aircraft.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 166 words
In a missile adapted to be carried by an aircraft and having a traction cable extending from the missile to the aircraft, a control mechanism for tripping a system in the missile the control mechanism comprising: a. a storage pulley on which the traction cable is wound, b. a trip control element for tripping a system of the missile, c. energy storage means for actuating said trip control element upon release of the energy in said energy storage means, d. a locking member movable between a locking position, in which it holds said energy storage means in an energy storing condition, and a release position, in which it permits said energy storage means to actuate said trip control element, and e. movable means responsive to substantially complete unwinding of the traction cable from said storage pulley for moving said locking member from its locking position to its release position, whereupon said energy storage means actuates said trip control element to trip the system in the missile.
Claim 2
Dependent Claim 166 words
In a missile adapted to be carried by an aircraft and having a traction cable extending from the missile to the aircraft, a control mechanism for tripping a system in the missile the control mechanism comprising: a. a storage pulley on which the traction cable is wound, b. a trip control element for tripping a system of the missile, c. energy storage means for actuating said trip control element upon release of the energy in said energy storage means, d. a locking member movable between a locking position, in which it holds said energy storage means in an energy storing condition, and a release position, in which it permits said energy storage means to actuate said trip control element, and e. movable means responsive to substantially complete unwinding of the traction cable from said storage pulley for moving said locking member from its locking position to its release position, whereupon said energy storage means actuates said trip control element to trip the system in the missile.
Claim 3
Dependent Claim 38 words
A control mechanism as defined in claim 1 including retaining means for preventing said movable means from moving said locking member until the force applied to said movable means by said storage pulley rises above a predetermined value.
Claim 4
Dependent Claim 67 words
A control mechanism as defined in claim 1 wherein said energy storage means includes a support fixed with respect to the missile, a mobile element, and resilient means compressed between said support and mobile element, said trip control element being operatively connected to said mobile element, and said locking member includes a stop for restraining movement of said mobile element against the force of said resilient means.
Claim 5
Dependent Claim 28 words
A control mechanism as defined in claim 3 wherein said trip control element includes a cable, and said mobile element is connected to one end of said cable.
Claim 6
Dependent Claim 55 words
A control mechanism as defined in claim 3 wherein said stop is mounted for rotation about a fixed axis, said stop having a radially extending eccentric portion arranged to be abutted by said mobile element, said eccentric portion being movable out of the path of movement of said mobile element upon rotation of said stop.
Claim 7
Dependent Claim 62 words
A control mechanism as defined in claim 2 wherein said movable means includes a finger mounted for rotation about the axis of rotation of said storage pulley, and a spiral spring interconnecting said finger and said storage pulley, and said retaining means prevents rotation of said finger until the force applied to said finger by said spring rises above a predetermined value.
Claim 8
Dependent Claim 29 words
A control mechanism as defined in claim 6 wherein said retaining means includes a shearable pin extending between said finger and a part fixed with respect to the missile.
Claim 9
Dependent Claim 52 words
A control mechanism as defined in claim 6 including a crank for rotating said locking member, said crank having an arm arranged in the path of movement of said finger, and said finger when it moves engaging said arm and rotating said locking member from its locking position to its release position.
Claim 10
Dependent Claim 40 words
A control mechanism as defined in claim 1 including resilient means for maintaining said locking means in its locking position until said movable means applies a force to said locking means sufficient to overcome the force of said resilient means.
