Abstract

A rail launch mechanism and method for launching a payload is configured to release payload lugs of a payload from a platform. A rack for launching a payload includes multiple rails that separately engage lugs in the respective payload of the rails, and a force actuator for launching the payload by accelerating the payload along the rails, causing the lugs to separate from the respective rails. A launching system for launching the payload from the platform may include a rail, at least one payload release shoe that carries a payload lug along the rail, and a force actuator for accelerating the payload release shoe such that inertia of the payload causes the payload lug to be released from the payload release shoe.

First claim

What is claimed is:

1. A rack for launching a payload, the rack comprising: multiple rails that separately engage payload lugs received in respective rails of the multiple rails wherein the multiple rails are parallel and offset from one another in a perpendicular direction relative to a length of the rack; and a force actuator for launching the payload by accelerating the payload along the multiple rails, causing the payload lugs to separate from the respective rails, wherein the force actuator is arranged to exert an accelerating force against one of the payload lugs that accelerates the one of the payload lugs along a corresponding one of the multiple rails thereby carrying the payload along the multiple rails.

2. The rack according to claim 1 , wherein the multiple rails are offset by a distance between 2 and 13 centimeters.

3. The rack according to claim 1 , wherein the force actuator is in-line with one of the multiple rails and offset relative to another one of the multiple rails.

4. The rack according to claim 1 , wherein the multiple rails have a stepped arrangement that ascends along a length of the rack opposite the force actuator.

5. The rack according to claim 1 , further comprising a frame having a base, wherein the multiple rails are offset relative to the base and the force actuator is in-line with one of the multiple rails which is farther away from the base relative to another one of the multiple rails.

6. The rack according to claim 1 , wherein the multiple rails are vertically offset and the payload is horizontally ejected from the rack.

7. The rack according to claim 1 , wherein the multiple rails each have a length that is less than a distance between the payload lugs.

8. The rack according to claim 1 , wherein the force actuator includes a telescoping piston and a ramrod that is engaged by the telescoping piston.

9. The rack according to claim 1 , wherein the force actuator includes at least one of an electrical actuator, a pneumatic actuator, a hydraulic actuator, or an explosive actuator.

10. The rack according to claim 1 further comprising at least one payload release shoe that is connected between one of the payload lugs and one of the multiple rails, wherein an inertia of the payload causes the payload lug to be released from the at least one payload release shoe.

11. The rack according to claim 10 , wherein the at least one payload release shoe includes a blocking piece and a hook that define a lug-retaining recess for the payload lug, the hook being hinged to the blocking piece for opening the lug-retaining recess to release the payload lug.

12. The rack according to claim 11 , further comprising a stop shoulder arranged at an end of a length of the rail, wherein the hook is engageable against the stop shoulder and the blocking piece is hinged for pivoting relative to the hook on an opposing side of the stop shoulder.

13. The rack according to claim 10 further comprising a plurality of payload release shoes, wherein each of the multiple rails includes a payload release shoe.

14. A launching system that includes the rack according to claim 1 and further comprises a plurality of racks that are vertically stacked.

15. The launching system according to claim 14 further comprising an electronic control unit that is configured to control each of the racks independently relative to other racks.

16. A rack for launching a payload, the rack comprising:
multiple rails that separately engage payload lugs received in respective rails of the multiple rails;
a force actuator for launching the payload by accelerating the payload along the multiple rails, causing the payload lugs to separate from the respective rails; and
at least one payload release shoe that is connected between one of the payload lugs and one of the multiple rails, wherein an inertia of the payload causes the payload lug to be released from the at least one payload release shoe,
wherein the at least one payload release shoe includes a blocking piece and a hook that define a lug-retaining recess for the payload lug, the hook being hinged to the blocking piece for opening the lug-retaining recess to release the payload lug.
