Abstract

Provided are systems, apparatus, and methods for pushing out and drilling a flare grain in an aerial flare. The system includes at least three stands including a first stand holding a first electric linear actuator positioned to interface with the aerial flare and push out a flare grain of the flare. The second stand holds the aerial flare and is positioned relative to the first stand to facilitate interface of the flare with the first electric linear actuator. The third stand includes a drill and is movable relative to the second stand for drilling a hole in the flare grain. A second electric linear actuator is coupled to the third stand device moves the third stand device relative the second stand to enable the drill to engage with the flare grain. The system also includes a controller/processor automating the pushing and drilling operations by controlling the electric linear actuators.

First claim

The invention claimed is:

1. A system for pushing out and drilling of a flare grain in an aerial flare comprising:
a first stand mounted to a base and configured to hold a first electric linear actuator with a throw rod positioned to interface with a first end of an aerial flare and exert a force on a first end of a flare grain within the aerial flare to cause the flare grain to move relative to a case of the aerial flare;
a second stand mounted to the base and configured to receive and fixedly hold the aerial flare;
a third stand mounted to the base and configured to be movable relative to at least the second stand and the aerial flare and further including a drilling device attached thereto;
a second electric linear actuator coupled to the third stand and configured to move the third stand and the attached drilling device relative to a second end of the flare grain to engage the drilling device with the second end of the flare grain for drilling a hole in at least one portion of the flare grain; and
a controller electrically coupled to the first and second electric linear actuators and configured to control the first and second electric linear actuators according to a predetermined sequence of operation.

2. The system of claim 1 , wherein the third stand further includes a catch tray affixed thereto and configured to be located under at least the second end of the aerial flare when the third stand is moved toward the second stand for drilling the hole in the at least one portion of the flare grain.

3. The system of claim 2 , wherein the second stand is configured with an opening allowing the catch tray to pass through the second stand and be positioned under at least the second end of the aerial flare.

4. The system of claim 1 , wherein the predetermined sequence includes:
operating the first electric linear actuator by the controller to exert the force on first end of the flare grain to cause an end cap of the aerial decoy located at the second end of the flare grain to be pushed off and expose the flare grain and also cause the flare grain to be at least partially pushed out of the case of the aerial flare at the second end of the aerial flare; and
operating the second electric linear actuator after operating the first electric linear actuator to cause the drilling device to contact the flare grain at the second end of the aerial flare and to drill the hole in the at least one portion of the flare grain.

5. The system of claim 4 , further comprising:
operating the first linear actuator after operating the second linear actuator and the drilling device to fully push the flair grain out of the case of the aerial flare.

6. The system of claim 1 , wherein the controller is further configured to control operation of the drilling device according to a predetermined drilling process coordinated with operation of the second electric linear actuator.

7. The system of claim 6 , wherein the predetermined drilling process includes operating the drilling device for a predetermined time period and operating the second electric linear actuator to cause the third movable stand to move toward the second stand at a predetermined rate and distance.

8. The system of claim 1 , wherein the third stand further comprises a rail disposed between an upper portion of the third stand and the base and configured to allow the third stand to move relative to the base.

9. An apparatus configured for pushing out and drilling a flare grain in an aerial flare, the apparatus comprising:
a base;
a first stand mounted to the base and including a first electric linear actuator with a throw rod positioned to interface with a first end of an aerial flare and exert a force on a first end of a flare grain within the aerial flare to cause the flare grain to move relative to a case of the aerial flare;
a second stand mounted to the base and configured to receive and fixedly hold the aerial flare;
a third stand mounted to the base and movable relative to at least the second stand, the third stand further including a drilling device attached to a top portion thereof;
a second electric linear actuator coupled to the third stand and configured to move the third stand and the attached drilling device relative to a second end of the flare grain to engage the drilling device with the second end of the flare grain for drilling a hole in at least one portion of the flare grain; and
a processor communicatively coupled to the first and second electric linear actuators and configured to control the first and second electric linear actuators according to a pre-programmed sequence of operation.

10. The apparatus of claim 9 , wherein the third stand further includes a catch tray orthogonally affixed to a vertical wall portion of the third stand and configured to be located under at least the second end of the aerial flare when the third stand is moved toward the second stand for drilling the hole in the at least one portion of the flare grain.

11. The apparatus of claim 10 , wherein the second stand is configured with an opening allowing the catch tray to pass through the second stand and be positioned under at least the second end of the aerial flare.

12. The apparatus of claim 9 , wherein the predetermined sequence includes the processor:
operating the first electric linear actuator by the controller to exert the force on first end of the flare grain to cause an end cap of the aerial decoy located at the second end of the flare grain to be pushed off and expose the flare grain and also cause the flare grain to be at least partially pushed out of the case of the aerial flare at the second end of the aerial flare; and
operating the second electric linear actuator after operating the first electric linear actuator to cause the drilling device to contact the flare grain at the second end of the aerial flare and to drill the hole in the at least one portion of the flare grain.

13. The apparatus of claim 12 , further comprising:
operating the first linear actuator after operating the second linear actuator and the drilling device to fully push the flair grain out of the case of the aerial flare.

14. The apparatus of claim 9 , wherein the processor is further configured to control operation of the drilling device according to a predetermined drilling process coordinated with operation of the second electric linear actuator.

15. The apparatus of claim 14 , wherein the predetermined drilling process includes the processor operating the drilling device for a predetermined time period and operating the second electric linear actuator to cause the third movable stand to move toward the second stand at a predetermined rate and distance.

16. The apparatus of claim 9 , further comprising a shield mounted to the third stand and configured to encompass the drilling device to shield the flare grain from electric arcs or sparks that occur in the drilling device.

17. A method for pushing out and drilling of a flare pyrotechnic substance of an aerial flare comprising:
mounting an aerial decoy flare to a unit under test (UUT) stand;
initiating a push out sequence wherein a first electric linear actuator is operated to cause a push rod of the first electric linear actuator to exert a pushing force on a first end of the flare to push out an end cap of flare, as well as push at least a portion of the flare pyrotechnic substance of a casing of the flare;
initiating a drilling sequence wherein a drilling device is started and a second linear electric actuator is operated to move a movable stand holding the drilling device to engage with a sec
