Missile launcher with ejection shoe

Claim 2

A missile launcher for use on an aircraft, comprising: a supporting structure arranged for being secured to the framework of an aircraft; connecting means for releasably securing a missile of elongated shape along a predetermined direction on said structure; a bearing shoe shaped to contact said missile over a sufficient length along said direction for maintaining said missile in a predetermined position with respect to said shoe; a plurality of links pivotally connected to said shoe and to said structure by pivotal connections, which pivotal connections are distributed at points so selected that said links, said supporting structure and said bearing shoe behave like a deformable quadrilateral; and fluid pressure actuated means for successively releasing said connecting means and actuating said links in a direction causing the shoe to push the missile away from said structure upon energization of said pressure actuated means.

Claim 3

A missile launcher according to claim 1, wherein said quadrilateral is substantially a parallelogram.

Claim 4

A missile launcher according to claim 1, wherein one at least of the pivotal connections of said links with said structure comprises support means pivotally supporting one of said links and provided with means for mechanically connecting it to said structure in an adjustable position.

Claim 5

A missile launcher for use on an aircraft, comprising: a supporting structure; a connecting means for releasably securing a missile of elongated shape along a predetermined direction on said structure; a bearing shoe shaped to contact said missile over a sufficient length along said direction for maintaining said missile in a predetermined position with respect to said shoe; a plurality of links pivotally connected to said shoe and to said structure by pivotal connections which pivotal connections are distributed at points so selected that said links, said supporting structure and said bearing shoe behave like a deformable parallelogram; and fluid pressure actuated means for successively releasing said connection means and actuating said links in a direction causing said shoe to push the missile away from said structure upon energization of said pressure actuated means, wherein said connecting means comprise a rail on said structure arranged to slidably receive fittings of said missile, whereby said missile may be engaged onto said rail by moving the missile forwardly, and locking means for engaging one of the fittings upon the forward movement of the missile and latching the missile in position, and wherein said fluid pressure actuated means includes a pressure cylinder operatively connected to one at least of said links and to said locking means for moving said locking means and fitting forwardly out of said rail upon energization thereof.

Claim 6

A missile launcher for use on an aircraft, comprising: a supporting structure; a connecting means for releasably securing a missile of elongated shape along a predetermined direction on said structure; a bearing shoe shaped to contact said missile over a sufficient length along said direction for maintaining said missile in a predetermined position with respect to said shoe; a plurality of links pivotally connected to said shoe and to said structure by pivotal connections which pivotal connections are distributed at points so selected that said links, said supporting structure and said bearing shoe behave like a deformable parallelogram; and fluid pressure actuated means for successively releasing said connection means and actuating said links in a direction causing said shoe to push the missile away from said structure upon energization of said pressure actuated means, wherein said connecting means comprise a rail on said structure arranged to slidably receive fittings of said missile, whereby said missile may be engaged onto said rail by moving the missile forwardly, and locking means for engaging one of the fittings upon the forward movement of the missile and latching the missile in position, and wherein said fluid pressure actuated means includes a pressure cylinder operatively connected to one at least of said links and to said locking means for moving said locking means and fitting forwardly out of said rail upon energization thereof.

Claim 7

A missile launcher according to claim 1, wherein said cylinder has a casing connected to said structure and a piston unit movable with respect to said cylinder over a predetermined rectilinear stroke and said piston unit has a one-way connection with said locking means to cause missile release during a first portion of said stroke and has a lost motion connection with said one of said links to cause ejection of said missile by said shoe during a second portion of said stroke.

Claim 8

A missile launcher according to claim 1, wherein said fluid pressure actuated means comprise: a first gas pressure cylinder for releasing said connecting means; and a second gas pressure cylinder for actuating said links, said first pressure cylinder being connectable to a pressurized gas source, said first and second gas pressure cylinders being connected by gas transfer means including a valve arranged to be opened responsive to full actuation of said first gas pressure cylinder whereby the second cylinder is energized only after the first cylinder has completed release of said missile.
