Abstract

This apparatus proposes to sequentially deploy stores, such as mines or missiles, from a moving vehicle, such as an airplane or ship, at a predetermined rate and velocity. It includes modular palletized stowage of these stores, limited in size and shape only by vehicle weight and/or space considerations, devices to lock the pallets together and to the vehicle, a cradle to support and facilitate propulsion of the stores prior to launch, a drive mechanism to propel the stores through the pallets, and devices to properly release each store from the vehicle and from its cradle.

Claims

1. A deployment apparatus for stores from a vehicle during movement comprising:

at least one carrier pallet formed by a plurality of parallel cradles each adapted to receive and secure one of said stores;

releasable lock elements on each said pallet complemental to, for coaction with, lock elements on adjacent stationary structure of the vehicle operable to immovably secure said at least one pallet on said vehicle against relative movement;

releasable connector elements carried by each said pallet to permit the interconnection of each said pallet with another similar pallet in vertical alignment;

a drive mechanism engageable between each said pallet and cradle and operative to move said cradle linearly relative to said pallet;

releasable coupling elements carried by each said drive mechanism whereby each said pallet is connectable to another said pallet with the cradles thereof disposed in fore and aft alignment;

a releasable mechanism operative to permit movement of each said store relative to its cradle; and

an actuator for the operation of said release mechanism at a predetermined location of said cradle in its movement by said drive mechanism.

2. The apparatus of claim 1 including complemental anti-friction elements carried by each said cradle and each said pallet to facilitate the relative linear movement of the cradle along the pallet when free to do so upon release of said lock elements and the operation of said drive mechanism as aforesaid.

3. The apparatus of claim 1 wherein multiple pallets are connected in fore and aft alignment and including an interconnection between the coacting lock elements aforesaid, and an actuator for said interconnection for the release of all said pallets in unison.

4. The apparatus of claim 1 wherein multiple pallets are connected in tiers and including an interconnection between said connector elements, and an actuator for said interconnection for the release of all said pallets in each tier in unison.

5. The apparatus of claim 1 wherein said release mechanism includes a plurality of straps between each said cradle and its associated store, at least one interconnection between all of said straps, and an actuator for said at least one interconnection for the release of all said straps in unison.

6. The apparatus of claim 1 wherein said drive mechanism includes a rack carried by each said cradle, a pinion gear carried by each said pallet, a drive shaft common to the pinion gears associated with each pair of adjacent cradles, and a clutch and brake operatively connected between each said pinion gear and said drive shaft.

7. The apparatus of claim 1 including an ejector module adjacent the aft end of said at least one pallet and having a bay corresponding to and aligned with each said cradle, anti-friction elements within each of said bays to receive and support each cradle as said cradle moves upon operation of said drive mechanism as aforesaid, and an independent drive mechanism carried by said ejector module operative at a preselected speed relative to that of each cradle drive mechanism aforesaid.

8. The apparatus of claim 7 wherein said release mechanism is carried by each cradle and includes at least one hook engageable with each end of a strap extending around each store and terminating on each side of said cradle, a trigger operatively connected to each said hook, and a tripper carried by said ejector module at the aft end thereof adjacent each bay to actuate each said trigger.

9. The apparatus of claim 7 wherein said independent drive mechanism is operative at a speed greater than that of each said cradle drive mechanism to thereby accelerate movement of each cradle therethrough.

10. The apparatus of claim 9 wherein said vehicle is an airplane having an internal hold with an opening in the aft end thereof and a door normally closing said opening, said door being movable to permit access to said hold, and wherein multiple pallets are connected in fore and aft alignment and in tiers.
