Abstract

Abstract A gunnery training system comprising a fire control unit located at a trainee location and including an aiming sight, an aiming controller, and a trigger; a video display viewable through the aiming sight and providing a field of view through the aiming sight corresponding to the actual view of a target through the aiming sight of an actual gun; apparatus for sensing the orientation of the trainee's line of sight or of a simulated or actual gun provided by the operation of the aiming controller by the trainee; apparatus for determining the trajectory of a simulated projectile relative to the target provided by the sensed orientation produced by the trainee's operation of the aiming controller; a library of video records of actual projectile trajectories and impacts for various orientations of an actual gun relative to the target shown on the display as seen through the aiming sight; and apparatus responsive to operation of the trigger and to an output from the determining apparatus for selecting a video record from the library and displaying it on the display in a time relationship to trigger actuation which corresponds generally to the time relationship between trigger actuation and the displayed events in actual firing.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 272 words
A fully recorded image gunnery training system comprising: a fire control unit located at a trainee location and including: an aiming sight; an aiming controller operative to control the orientation of an actual or simulated gun; and a trigger; a display viewable through said aiming sight and providing a field of view of a simulated target through said aiming sight corresponding to the actual view of an actual target through the aiming sight of an actual gun; means for sensing the orientation of said gun produced by operation of said aiming controller by a trainee; means for determining the trajectory of a simulated projectile relative to said simulated target in accordance with the orientation produced by operation of said aiming controller by said trainee; means to store a plurality of video records of actual recorded projectile firings said storing means including a video disc library having video records each of about 3-8 seconds duration and including the continuous dynamic effects in the trajectory as would be seen from the location of said actual gun with projectile impact and accompanying sounds for various orientations of said actual gun relative to said actual target corresponding to said simulated target shown on said display means for accessing said video disc library to display said video to the user; and means responsive to operation of said trigger and to an output from said determining means for selecting a video record from said library and displaying it on said display in a time relationship to trigger actuation by the trainee which corresponds generally to the time relationship between trigger actuation and the displayed events in actual firing.
Claim 2
Dependent Claim 272 words
A fully recorded image gunnery training system comprising: a fire control unit located at a trainee location and including: an aiming sight; an aiming controller operative to control the orientation of an actual or simulated gun; and a trigger; a display viewable through said aiming sight and providing a field of view of a simulated target through said aiming sight corresponding to the actual view of an actual target through the aiming sight of an actual gun; means for sensing the orientation of said gun produced by operation of said aiming controller by a trainee; means for determining the trajectory of a simulated projectile relative to said simulated target in accordance with the orientation produced by operation of said aiming controller by said trainee; means to store a plurality of video records of actual recorded projectile firings said storing means including a video disc library having video records each of about 3-8 seconds duration and including the continuous dynamic effects in the trajectory as would be seen from the location of said actual gun with projectile impact and accompanying sounds for various orientations of said actual gun relative to said actual target corresponding to said simulated target shown on said display means for accessing said video disc library to display said video to the user; and means responsive to operation of said trigger and to an output from said determining means for selecting a video record from said library and displaying it on said display in a time relationship to trigger actuation by the trainee which corresponds generally to the time relationship between trigger actuation and the displayed events in actual firing.
Claim 3
Dependent Claim 43 words
A system according to claim 1 and also comprising means for providing additional sensible stimuli to the trainee in response to trigger actuation and in a time relationship thereto which corresponds to the application of such stimuli to a gunner during actual firing.
Claim 4
Dependent Claim 16 words
A system according to claim 2 and wherein said sensible stimuli simulate the sounds of firing.
Claim 5
Dependent Claim 22 words
A system according to claim 2 and wherein said sensible stimuli simulate the sounds of impacting projectile as heard by a gunner.
Claim 6
Dependent Claim 33 words
A system according to claim 2 and wherein said sensible stimuli include visual stimuli which simulate the flash produced by firing and the temporary obscuration of the gunner's vision occuring immediately after firing.
Claim 7
Dependent Claim 21 words
A system according to claim 2 and wherein said sensible stimuli include force stimuli to simulate the recoil of the gun.
Claim 8
Dependent Claim 26 words
A system according to claim 2 and also comprising instructor monitoring means arranged to enable an instructor to view the same display seen by the trainee.
Claim 9
Dependent Claim 18 words
A system according to claim 2 and wherein said accessing means comprises a conventional industrial video disk player.
Claim 10
Dependent Claim 15 words
A system according to claim 2 wherein said gunnery training system is a tank trainer.
Claim 11
Dependent Claim 26 words
A system according to claim 1 and also comprising instructor monitoring means arranged to enable an instructor to view the same display seen by the trainee.
Claim 12
Dependent Claim 18 words
A system according to claim 1 and wherein said accessing means comprises a conventional industrial video disk player.
Claim 13
Dependent Claim 15 words
A system according to claim 1 wherin said gunnery training system is a tank trainer.
