Abstract

In one possible embodiment, a UAV payload module retraction mechanism is provided including a payload pivotally attached to a housing. A biasing member is mounted to bias the payload out of the housing and a winch is attached to the payload. An elongated flexible drawing member is coupled between the housing and the winch, the elongated drawing flexible member being capable of being drawn by the winch to retract the payload within the housing.

First claim

What is claimed is:

1. A method in a UAV comprising:
a) installing in the UAV a payload module comprising a payload secured therewithin so as to be capable of stowing the payload within the UAV and deploying the payload out of the UAV;
b) biasing the payload out of the UAV into a deployed position;
c) retracting the payload using a flexible means capable of supporting tension; and
d) wherein retracting using the flexible means comprises causing the payload to retract into the UAV from the deployed position while biasing the payload out of the UAV.

2. The method of claim 1 , wherein retracting using the flexible means comprises using at least one of: a) a cable; or b) a belt.

3. The method of claim 2 , wherein retracting using the flexible means comprises using a corrosion resistant material.

4. The method of claim 3 , wherein retracting using the flexible means comprises a KEVLAR belt.

5. The method of claim 1 , wherein biasing comprises providing sufficient force to keep the payload stable when the payload is deployed out of the UAV into an airstream.

6. The method of claim 1 further comprising locking the payload in the deployed position to secure the payload in the deployed position.

7. The method of claim 1 , wherein securing the payload comprises securing with a hinge.

8. The method of claim 1 , wherein retracting the payload comprises using a winch.

9. A UAV comprising:
a) a payload module comprising a deployable payload; and
b) a retraction mechanism apparatus capable of moving the payload from a stowed position within the UAV to a deployed position extending out of the UAV, the retraction mechanism being configured such that the payload retracts back into the UAV upon contact with a landing surface if the payload is not retracted before the UAV contacts the landing surface.

10. The UAV of claim 9 , wherein the UAV is a UAV without landing gear.

11. The UAV of claim 10 , wherein the UAV comprises a skid pad for landing on hard surfaces.

12. The UAV of claim 11 , wherein the UAV is an amphibious UAV.

13. The UAV of claim 12 , wherein the UAV is a hand launched UAV.

14. The UAV of claim 10 , wherein the UAV is an amphibious UAV.

15. The UAV of claim 10 , wherein the UAV is a hand launched UAV.

16. The UAV of claim 9 , wherein the payload module comprises a biasing member to bias the deployable payload out of the payload module.

17. The UAV of claim 16 , wherein the retraction mechanism apparatus comprises a flexible drawing member coupled to the deployable payload.

18. The UAV of claim 17 , wherein the flexible drawing member is not capable of exerting a pushing force on the deployable payload.
