Abstract

An ejection system for ejecting a payload from a payload delivery vehicle is provided. The ejection system includes an airbag ejection system configured to eject the payload from the payload delivery vehicle, a payload separation system configured to selectively couple the payload to the airbag ejection system, and a controller configured to inflate the airbag ejection system and further configured to signal the payload separation system to release the payload from the airbag ejection system.

Claims

1. An airbag ejection system for ejecting a payload from a payload delivery vehicle, comprising:

a base coupled to the payload delivery vehicle;

an airbag coupled to the base;

a payload separation system configured to selectively couple the payload to the airbag;

a motor configured to inflate the airbag;

a controller configured to engage the motor to inflate the airbag and further configured to control release of the payload by the payload separation system; and

a sensor configured to determine a position of the payload relative to a position of the payload delivery vehicle;

wherein the controller is further configured to signal the payload separation system to release the payload from the airbag ejection system based at least in part upon the position of the payload relative to the position of the payload delivery vehicle determined by the sensor.

2. The airbag ejection system of claim 1, further comprising a sleeve substantially covering the airbag, wherein the airbag has at least one stage, the at least one stage having at least one inflatable chamber therein.

3. The airbag ejection system of claim 2, further comprising:

a valve system coupled to the airbag, the valve system configured to selectively fill the at least one inflatable chamber of the airbag,

wherein the controller is further configured to determine an ejection angle based upon the position of the payload relative to the position of the payload delivery vehicle and to engage the motor and the valve system to fill the airbag and eject the payload from the payload delivery vehicle at the ejection angle.

4. The airbag ejection system of claim 3, wherein the sensor is further configured to determine a position of the payload relative to a position of a target of the payload, and the controller is further configured to determine the ejection angle which would eject the payload towards the target.

5. The airbag ejection system of claim 4, wherein the payload delivery vehicle is an airborne munition.

6. The airbag ejection system of claim 5, wherein the airborne munition is configured to operate in an outer atmosphere.

7. The airbag ejection system of claim 3, wherein the valve system further comprises a plurality of deployment systems, each of the plurality of deployment systems configured to fill the at least one inflatable chamber in the airbag such that the payload is ejected at a unique angle relative to the payload delivery vehicle.
