Patent ID: 7395761

Claim:
A Variable-Force Payload Ejecting System for selectively ejecting items from the payload bay of an air vehicle, said air vehicle having therein a controlling computer for calculating amounts of pressure necessary for variously-timed ejections and producing output signals indicative of said calculated necessary amounts of pressure, said ejecting system residing within the air vehicle and comprising: a plurality of pressure generators; an electronics module coupled to the controlling computer, said electronics module activating at least one of said pressure generators in response to the output signals from the controlling computer to produce the calculated necessary amount of pressure at pre-determined times; an inflatable tube positioned adjacent to the items; a helical stiffener fixedly attached to said inflatable tube and producing a pre-selected spin rate to the items; and a means to transmit the pressure from said generator to said tube so as to cause said tube to inflate and thereby eject the items such that the items fall on pre-selected loci.
