Abstract

A training apparatus, method and kit for remotely and substantially instantaneously evaluating the alignment, settings and levels of the aiming devices of a howitzer gun. The apparatus includes a video camera for manually removably attaching to the pantel and receiving the sight picture in the pantel or displaying a sight picture in a pantel eyepiece, a pantel deflection setting encoder for manually removably attaching to a pantel deflection setting device and encoding signals responsive to the pantel deflection setting, a pantel level encoder for manually removably attaching to the pantel and encoding signals responsive to the pantel level, a quadrant setting encoder for manually removably attaching to the quadrant setting device and encoding a signal responsive to the quadrant setting, a quadrant level encoder for manually removably attaching to the quadrant and encoding signals responsive to a quadrant level, and a data processing computer for receiving and analyzing the sight picture, or displaying or controlling a synthetic sight picture in a pantel eyepiece, for receiving the signals and for evaluation of the alignment, settings and levels.

Claims

1. A training apparatus for a howitzer gun aiming device, which aiming device includes a pantel capable of viewing a sight picture of a distant collimator for alignment of the pantel with the collimator, a pantel deflection setting means for setting a pantel deflection and a gun deflection, a pantel level indicator for indicating a pantel level, a quadrant setting means for setting a quadrant and a gun elevation, and a quadrant level indicator for indicating a level of the quadrant, comprising:

(1) a video means which is manually removably attachable to the pantel for receiving the sight picture in the pantel or for displaying a synthetic sight picture in a pantel eyepiece;

(2) a pantel deflection setting encoder which is manually removably attachable to the pantel deflection setting means for encoding signals responsive to a pantel deflection setting;

(3) a pantel level encoder which is manually removably attachable to the pantel for encoding signals responsive to a pantel level;

(4) a quadrant setting encoder which is manually removably attachable to the quadrant setting means for encoding signals responsive to a quadrant setting;

(5) a quadrant level encoder which is manually removably attachable to the quadrant for encoding signals responsive to a quadrant level; and

(6) a data processing computer for receiving and analyzing the sight picture, or for displaying and controlling the synthetic sight picture in the pantel eyepiece, and for receiving the signals and evaluating the alignment, settings and levels.

2. The apparatus of claim 1 wherein the video means receives a sight picture having an image in the pantel and the video means has an optical beam splitter for splitting the image in the pantel into two image beams with one image beam being directed to an eyepiece of the video means and one image beam being directed to a lens of a video camera.

3. The apparatus of claim 2 wherein the beam splitter is in close proximity to the eyepiece.

4. The apparatus of claim 2 wherein the video camera is a computer controlled camera and a collimator image can be displayed more brightly than background images.

5. The apparatus of claim 2 wherein the image in the pantel has a reticle and a collimator picture of the collimator has a reticle and alignment of the gun is achievable by aligning the reticles.

6. The apparatus of claim 5 wherein the computer is capable of comparing the reticle of the collimator picture with the reticle of the pantel so as to determine the accuracy of the alignment.

7. The apparatus of claim 1 wherein the pantel deflection setting encoder is attachable to a pantel deflection setting input device.

8. The apparatus of claim 7 wherein pantel deflection setting encoder has a pantel deflection setting input device which is substantially the same as the pantel deflection setting input device, so that an operation of the encoder input device is substantially the same as an operation of the setting input device.

9. The apparatus of claim 1, wherein the pantel level encoder is an inclinometer.

10. The apparatus of claim 9, wherein the inclinometer is capable of determining the level and a cross-level of the pantel.

11. The apparatus of claim 10, wherein the inclinometer is a two-axis electrolytic tilt sensor.

12. The apparatus of claim 1, wherein the quadrant setting encoder is attachable to a quadrant setting input device.

13. The apparatus of claim 12, wherein the quadrant setting encoder has a quadrant setting input device which is substantially the same as the quadrant setting input device, so that an operation of the encoder input device is substantially the same as an operation of the setting input device.

14. The apparatus of claim 1 wherein the quadrant level encoder is an inclinometer.

15. The apparatus of claim 14, wherein the inclinometer is capable of determining the level and a cross-level of the quadrant.

16. The apparatus of claim 15, wherein the inclinometer is a two-axis electrolytic tilt sensor.

17. The apparatus of claim 1, wherein the computer is capable of communicating with a distant read-out device such that an evaluation of the alignment, settings and levels may be made at a distance from the computer.

18. The apparatus of claim 17, wherein the read-out device is a computer.

19. The apparatus of claim 1, wherein the video means displays a sight picture and the video means includes a video monitor for displaying a synthetic video sight picture of a collimator and background thereof in an eyepiece of the video means.

20. The apparatus of claim 19, wherein an encoder detects motion of the gun turret.

21. The apparatus of claim 1 wherein the video means, pantel deflection setting encoder, pantel level encoder, quadrant setting encoder and quadrant level encoder are enclosable in and hand carryable with a hand carrying case.

22. A training method for remotely and substantially instantaneously evaluating the aiming alignment, settings and levels set by a crew training on a howitzer gun, comprising:

(1) manually removably attaching to a pantel of the gun a video means for receiving a sight picture in the pantel or for displaying a synthetic sight picture in a pantel eyepiece;

(2) manually removably attaching to a pantel deflection setting means a pantel deflection setting encoder for encoding signals responsive to a pantel deflection setting;

(3) manually removably attaching to the pantel a pantel level encoder for encoding signals responsive to a pantel level;

(4) manually removably attaching to a quadrant setting means a quadrant setting encoder for encoding signals responsive to a quadrant setting;

(5) manually removably attaching to a quadrant a quadrant level encoder for encoding signals responsive to a quadrant level; and

(6) receiving in a data processing computer said sight picture, or the data processing computer displaying and controlling the synthetic sight picture in a pantel eyepiece, and receiving in the data processing computer said signals for evaluation of the alignment, settings and levels.
