Abstract

A container is used to launch a small aircraft, such as an unmanned aerial vehicle (UAV), from a host aircraft. The container protects the UAV from stresses during the initial ejection from a launcher that is part of the host aircraft. The initial stresses may be due to turbulence in the vicinity of the host aircraft, high airspeed, and/or tumbling that may result from the ejection from the host aircraft moving at a high airspeed. The container may deploy a drag device, such as a drogue chute, to slow the container down and reorient the container, prior to deployment of the UAV from the container. During the time between ejection from the host aircraft and deployment from the container, the UAV may be powered up and acquire data, such as global positioning system (GPS) data, to allow the UAV a “hot start” enabling immediate mission commencement.

First claim

What is claimed is:

1. An air-launched container that in turn launches an air vehicle, the container comprising:
a sleeve that defines a volume therein that receives the air vehicle;
a deployable drag device attached to the sleeve;
a release mechanism within the sleeve, for mechanically releasing the air vehicle from the sleeve; and
a nose that is mechanically coupled to the sleeve, and that separates from the sleeve and the air vehicle as the air vehicle is launched from the sleeve; and
wherein, when the release mechanism is released, the air vehicle is fully contained within the volume defined by the sleeve, and is free to slide within the volume relative to the sleeve and the nose, after release of the release mechanism and prior to separation of the nose from the sleeve and the air vehicle, wherein a forward sliding of the air vehicle causes the separation of the nose from the sleeve.

2. The container of claim 1 , wherein the container includes logic for communication between the air vehicle and a host aircraft.

3. The container of claim 1 , wherein the drag device includes a parachute.

4. The container of claim 1 , wherein the sleeve includes deployable fins that deploy after ejection of the container from a launcher, and before release of the air vehicle from the sleeve.

5. The container of claim 1 , wherein the sleeve is made of metal.

6. The container of claim 1 , wherein the sleeve is made of a biodegradable material.

7. The container of claim 1 , further comprising a drag device release within the sleeve that is operatively coupled to the drag device to deploy the drag device.

8. The container of claim 1 , in combination with the air vehicle.

9. The combination of claim 8 , wherein the air vehicle is an unmanned air vehicle that has a fuselage and deployable aerodynamic surfaces that are coupled to the fuselage.

10. The combination of claim 8 , in combination with a launcher that deploys the container from a host aircraft that is mechanically coupled to the launcher.

11. The combination of claim 10 ,
wherein the launcher includes a plunger in contact with the nose of the container; and
wherein the plunger is used to push the container out of the launcher.

12. The combination of claim 11 , wherein the launcher includes a gas cartridge that is operatively coupled to the plunger, to push the plunger to thereby push the nose of the container.

13. The combination of claim 10 , wherein the launcher includes a pair of mounts for mounting to a host aircraft.

14. The combination of claim 8 , wherein release of the release mechanism allows the air vehicle to slide within the container toward the nose.

15. The container of claim 1 , wherein the volume is in an interior of the container, fully closed off from an exterior of the container by the sleeve and the nose.

16. The container of claim 1 , wherein the release mechanism includes a mechanical release.

17. The container of claim 1 , wherein the nose engages a lip of the sleeve.

18. The container of claim 1 ,
further comprising a first wiring harness and a second wiring harness that together provide a wired connection between the air vehicle and a host aircraft that the container is launched from;
wherein the first wiring harness runs from the host aircraft to the nose of the sleeve;
wherein the first wiring harness disconnects when the container is ejected from a launcher that is part of the host aircraft; and
wherein the second wiring harness disconnects when the air vehicle separates from the container.
