Abstract

A base of a TOW missile system is mounted on a rotatable turret of a vehicle and is also rotatably mounted relative to the rotation of the turret so that the orientation of the base about its own rotational axis remains stationary. The positioning of the TOW base on the turret allows the turret to rotate generally about an axis which can be aligned with the person operating the sight. Thus the diameter of the opening in the vehicle is reduced. One embodiment uses a planetary gear system for holding the orientation of the base. A second embodiment uses a flexible link.

Claims

1. A vehicular turret mounting system for a TOW missile system of the type having a traversing unit, said traversing unit having a means providing an elevation pivot axis, an optical sighting and tracking unit mounted for movement about said axis, handle means for manually traversely rotating said traversing unit, means for elevationally pivoting said sighting and tracking unit, and a base having viscous bearing means supporting said traversing unit and for providing a resistance to said manual traverse rotation of the traversing unit, the improvement comprising:

a vehicle having a hull, an opening in the hull, and a turret supported for rotational movement about a turret axis concentric with said hull opening, at least one missile launch tube elevationally pivotally mounted on said turret, a personnel station in said opening generally aligned with said turret axis, means mounting said traversing unit on said turret adjacent the periphery of said hull opening offset from said turret axis, said mounting means including means for holding the orientation of said base stationary with said hull for simulating a ground-supported TOW missile system, and servo means for traversing said turret in response to movements of said traversing unit on said base.

2. The system of claim 1, said orientation holding means including a gear system coupled to said turret and having a plurality of meshed gears of ratios providing a counter rotation to said base equal to the turning distance caused by movements of the turret.

3. The system of claim 2, said gear system including a planetary gear train.

4. The system of claim 1, said orientation holding means including a flexible, non-rotatable link coupled at one end to said hull and at another end to said base.

5. The system of claim 1, wherein said sighting and tracking unit are pivotally mounted on said traversing unit.

6. A vehicular weapon control system comprising at least one weapon mounted on a rotatable turret, said turret being rotatably supported for movement about a turret axis, sighting and tracking means, means supporting the sighting and tracking means on said turret for movement therewith and for rotational movement about a traverse axis offset from said turret axis, said supporting means including a base, servo means for rotating said turret in response to traverse rotation of said sighting and tracking means, and means for holding the base rotationally stationary relative to rotation of said turret axis.

7. The system of claim 6, said base including viscous dampening means to dampen movements of said sighting and tracking means on said base.

8. The system of claim 7, said means for holding the base including gear means for providing a rotation to the base counter to rotation of the turret and proportional thereto so that the base maintains a fixed orientation.

9. The system of claim 8, said gear means including a planetary gear train.

10. The system of claim 7, said means for holding the base including a flexible, non-rotatable link fixed to the vehicle hull.

11. The system of claim 7, said weapon including a missile launch tube mounted for elevational pivoting on said turret, said launch tube movable about a first elevational axis, said sighting and tracking means mounted on said supporting means for elevational pivotal movement about a second elevational axis concentric with said first elevational axis.
