Abstract

Embodiments of a submersible transport and launch canister are provided for use by a diver in the deployment of an airborne object. In one embodiment, the submersible transport and launch canister includes a pressure vessel having an open end portion and a storage cavity configured to receive the airborne object therein. A diver-actuated cap is movable between an open position and a closed position in which the diver-actuated cap sealingly engages the open end portion. A propellant device is fluidly coupled to the storage cavity and is configured to propel the airborne object from the storage cavity and through the open end portion when the propellant device is actuated by the diver.

Claims

1. A submersible transport and launch canister for use by a diver in the deployment of an airborne object, the submersible transport and launch canister comprising:

a pressure vessel having an open end portion and a storage cavity configured to receive the airborne object therein;

a weighted lever arm assembly movably coupled to the pressure vessel;

a diver-actuated cap movable between an open position and a closed position in which the diver-actuated cap sealingly engages the open end portion; and

a propellant device fluidly coupled to the storage cavity and configured to propel the airborne object from the storage cavity and through the open end portion when the propellant device is actuated;

wherein the weighted lever arm assembly is movable relative to the pressure vessel to tilt the pressure vessel.

2. A submersible transport and launch canister according to claim 1 wherein the propellant device comprises a pressurized gas reservoir fluidly coupled to the storage cavity.

3. A submersible transport and launch canister according to claim 2 wherein the propellant device further comprises a fill port fluidly coupled to the pressurized gas reservoir and manually accessible from the exterior of the submersible transport and launch canister.

4. A submersible transport and launch canister according to claim 2 further comprising:

a flow control valve fluidly coupled between the pressurized gas reservoir and the storage cavity, the flow control valve normally residing in a closed position wherein the flow control valve substantially prevents pressurized gas flow from the pressurized gas reservoir to the storage cavity;

an actuator operably coupled to the flow control valve; and

a diver launch control operably coupled to the actuator and, when actuated, configured to cause the actuator to move the flow control valve into an open position.

5. A submersible transport and launch canister according to claim 4 further comprising an elongated tether operably coupling the diver launch control to the actuator.

6. A submersible transport and launch canister according to claim 1 wherein the diver-actuated cap is biased toward the open position, and wherein the submersible transport and launch canister further comprises a manual cap actuation mechanism engaging the diver-actuated cap in the closed position.

7. A submersible transport and launch canister according to claim 6 wherein the manual cap actuation mechanism comprises a pull pin.

8. A submersible transport and launch canister according to claim 1 further comprising a vacuum port fluidly coupled to the storage cavity.

9. A submersible transport and launch canister according to claim 1 further comprising a pressure relief valve fluidly coupled to the storage cavity and configured to vent gas from the storage cavity when the pressure therein surpasses a predetermined threshold.

10. A submersible transport and launch canister according to claim 1 wherein the weighted lever arm assembly comprises:

a drogue weight; and

a lever arm having a first end portion hingedly coupled to the pressure vessel and having a second end portion fixedly coupled to the drogue weight.

11. A submersible transport and launch canister according to claim 10 wherein the weighted lever arm assembly is movable between a deployed position and a non-deployed position, wherein the drogue weight resides substantially adjacent the pressure vessel in the non-deployed position, and wherein the drogue weight is angularly displaced from the pressure vessel in the deployed position.

12. A submersible transport and launch canister according to claim 11 wherein the weighted lever arm assembly is biased toward the deployed position, and wherein the submersible transport and launch canister further comprises a manual lever arm deploy mechanism engaging the weighted lever arm assembly in the non-deployed position.

13. A submersible transport and launch canister according to claim 12 wherein the manual lever arm deploy mechanism comprises a pull pin.

14. A submersible transport and launch canister according to claim 1 further comprising a variable-density flotation device coupled to the pressure vessel.

15. A submersible transport and launch canister according to claim 14 where the variable-density flotation device comprises an inflatable float collar mounted around the open end portion of the pressure vessel.

16. A submersible transport and launch canister according to claim 1 further comprising a waterproof membrane installed within the storage cavity over the airborne object.

17. A submersible transport and launch canister, comprising:

a pressure vessel having an open end portion and a storage cavity;

a weighted lever arm assembly movably coupled to the pressure vessel;

an airborne object stored within the storage cavity;

a diver-actuated cap movable between an open position and a closed position in which the diver-actuated cap sealingly engages the open end portion to impede the ingress of water into the storage cavity when the submersible transport and launch canister is submerged; and

a propellant device fluidly coupled to the storage cavity and, upon diver actuation, configured to propel the airborne object from the storage cavity and through the open end portion;

wherein the weighted lever arm assembly is movable relative to the pressure vessel to tilt the pressure vessel.

18. A submersible transport and launch canister according to claim 17 wherein the airborne object comprises an Unmanned Aerial Vehicle stored in the storage cavity in a non-deployed state.

19. A submersible transport and launch canister for deployment of an airborne object, the submersible transport and launch canister comprising:

a pressure vessel having an open end portion and a storage cavity configured to receive the airborne object therein;

a cap movable between an open position and a closed position in which the cap sealingly engages the open end portion;

a float collar mounted to the pressure vessel proximate the open end portion;

a weighted lever arm assembly hingedly coupled to the pressure vessel, wherein the weighted lever arm assembly is movable relative to the pressure vessel to tilt the pressure vessel; and

a propellant device coupled to the storage cavity and configured to launch the airborne object from the storage cavity and through the open end portion when the propellant device is actuated.
