Abstract

Claims (44)

1. A connection system comprising:

a lanyard release connector adapted for use with a vehicle and having a primary latching release mechanism adapted to hold a complementary connector of a payload and release the complementary connector when actuated such that the payload may be jettisoned from the vehicle; and

a secondary latching release mechanism adapted to couple the lanyard release connector to a lanyard, the secondary latching release mechanism comprising:

a spring; and

a latch adapted to hold the spring in a compressed position and release the spring when the latch is actuated by the lanyard, the spring configured to generate a force for actuating the lanyard release connector in which the force is co-axial with an axis of a connector housing of the lanyard release connector in which the force is co-axial with an axis of a connector housing of the lanyard release connector.

2. A connection system comprising:

a lanyard release connector having a primary latching release mechanism adapted to hold a complementary connector of a payload and release the complementary connector when actuated such that the payload may be jettisoned from a vehicle; and

a secondary latching release mechanism coupling the lanyard release connector to a lanyard, the secondary latching release mechanism comprising a mechanical forcing device that is operable to apply a force that actuates the primary latching release mechanism when the mechanical forcing device is actuated by the lanyard.

3. The connection system of claim 2 , wherein the forcing device is adapted to generate the force co-axially with an axis of a connector housing of the lanyard release connector.

4. The connection system of claim 2 , wherein the secondary latching release mechanism comprises:

a spring; and

a latch adapted to hold the spring in a loaded position and release the spring when actuated by the lanyard.

5. The connection system of claim 4 , further comprising a cable having a first end coupled to the mechanical forcing device and a second end coupled to the connector housing, the cable extending over a pulley such that the cable transfers a tension force from the mechanical forcing device to the connector housing in which the axis of the connector housing is not co-axial with the mechanical forcing device.

6. The connection system of claim 2 , wherein the mechanical forcing device comprises an electro-mechanical device adapted to generate the force in response to excitation of the electro-mechanical device with an electrical current.

7. The connection system of claim 6 , wherein the electro-mechanical device comprises an elongated section of muscle wire.

8. The connection system of claim 2 , wherein the vehicle comprises a military aircraft and the payload comprises one or more of the following:

a cache of munitions;

a cache of supplies;

a missile; and

a bomb.

9. The connection system of claim 2 , further comprising a lanyard coupled to the secondary latching release mechanism and adapted to be engaged over a bail bar of the vehicle, the lanyard release connector complying with a military standard 1760 (MIL-STD-1760) specification.

10. The connection system of claim 2 , wherein the lanyard release connector comprises a 90 degree backshell.

11. The connection system of claim 10 , wherein the 90 degree backshell has an oval-shaped port.

12. A connector coupling method comprising:

engaging a lanyard release connector on a complementary connector of a payload, the lanyard release connector adapted for use in a vehicle and having a primary latching release mechanism that holds the lanyard release connector on the complementary connector;

engaging a secondary latching release mechanism on the primary latching release mechanism, the secondary latching release mechanism comprising a mechanical forcing device that is coupled to the primary latching release mechanism, the mechanical forcing device adapted to be actuated by a lanyard such that the mechanical forcing device applies a force upon the primary latching release mechanism to release the lanyard release connector from the complementary connector of the payload.

13. The connector coupling method of claim 12 , further comprising:

generating, by the mechanical forcing device, the force co-axially with an axis of a connector housing of the lanyard release connector.

14. The connector coupling method of claim 12 , further comprising:

holding a spring in a loaded position using a latch, the spring comprising the mechanical forcing device; and

releasing the spring when the latch is actuated.

15. The connector coupling method of claim 14 , further comprising:

transferring a tension force from the mechanical forcing device to the lanyard release connector using a cable having a first end coupled to the mechanical forcing device and a second end coupled to the lanyard release connector, the cable extending over a pulley such that the axis of the connector housing is not co-axial with the mechanical forcing device.

16. The connector coupling method of claim 12 , further comprising:

generating the force using an electro-mechanical device by exciting the electro-mechanical device with an electrical current, the electro-mechanical device comprising the mechanical forcing device.

17. The connector coupling method of claim 16 , wherein the electro-mechanical device comprises an elongated section of muscle wire.

18. The connector coupling method of claim 12 , wherein the aircraft comprises an aircraft and the payload comprises one or more of the following:

a cache of munitions;

a cache of supplies;

a missile; and

a bomb.

19. The connector coupling method of claim 12 , further comprising:

engaging the lanyard over a bailbar of the aircraft, the lanyard release connector complying with a military standard 1760 (MIL-STD-1760) specification.

20. The connector coupling method of claim 12 , wherein the lanyard release connector comprises a 90 degree backshell.
