  • Patent number: 6997715
    Abstract: An integrated evaluation and simulation system for ground combat vehicles interactively evaluates concept design decisions and design requirements in the context of an operational ground combat vehicle. The combat effectiveness of a ground combat vehicle may also be concurrently tested by virtual simulation. A computer system is programmed to implement a causal network model comprising an integrated collection of analysis models for creating a virtual representation of a ground combat vehicle. The integrated evaluation and simulation system includes a user interface operatively coupled to at least the computer system to selectively input data into the causal network model and receive information therefrom, and at least one virtual simulation system. The system can further include either a virtual simulation system operatively coupled to the causal network model or, as part of the computer system, a virtual simulation system interface to communicate with a separate virtual simulation system.

  • Patent number: 6885332
    Abstract: The present invention is a multi-piece barrel shroud which provides IR signature and radar backscatter reduction over the entire length of the barrel by utilization of special radar absorbing materials and shaped in accordance with commonly known radar signature reduction techniques. The interior of the shroud includes cooling passages for the circulation of ambient air by way of a forced air circulation system which provides IR reduction. To facilitate barrel movement while minimizing weight, the majority of the shroud is stationary and is independent of the gun barrel. At least one other piece of the shroud is attached to the barrel near the muzzle end and designed to move in unison with the muzzle during recoil. The recoiling portion of the shroud is sized to mate with an annular recess within the distal end of the stationary portion so as to provide continuous shielding of the barrel throughout the entire range of recoil displacement.

  • Patent number: 6866108
    Abstract: A vehicle for use on a battlefield, having a hull with at least one endless track unit mounted underneath, and with a plurality of selectively vertically moveable wheels. The endless track unit may cover substantially all of the bottom side of the vehicle and may wrap upward to cover a portion of the front of the vehicle. The vehicle may be operated with only the wheels, the wheels and the endless track unit in combination, or only the endless track unit in contact with the ground. The vehicle has a height variable suspension element, which may be a hydro-pneumatic spring, coupled to each wheel. The suspension elements are connected with a power unit and a control unit to allow selective controllability of suspension height, and corresponding extension or retraction of the wheels. The wheels may also be provided with a resilient suspension mechanism that is either separate or formed by the height variable suspension elements.

  • Patent number: 6752063
    Abstract: A multiple cell ammunition cradle system for a weapon wherein the rate of ammunition transfer and the consequent rate of fire of the weapon is independent of the azimuth angle of the weapon. The system generally includes a cradle having a rotor with a plurality of cells formed therein. The cradle may be disposed in a charging position and a loading position. When in the charging position, each of the cells is controllably, selectively alignable with an ammunition hoist to receive an ammunition component in each cell. When the cradle is pivoted into the loading position, the rotor may be positioned so that each of the cells is alignable with the barrel of the weapon so that the ammunition component may be loaded into the weapon and fired.

  • Patent number: 6661524
    Abstract: A method and apparatus for measuring ground height in front of a vehicle, such as a vehicle for clearing buried land mines, in which a scanning pulsed laser to used to scan along one or more lines in front of the vehicle, with such scanning being executed more slowly in certain regions where data is collected and more quickly in intermediate regions where data is not collected. The time of flight along those lines is measured, and using that measurement, the ground height calculated and stored, with the higher elevations being discarded as the representing the tops of vegetation and the lower elevations being representative of the ground height or elevation in front of blade. A dozer blade on the vehicle is then adjusted in response to the calculated height to position the blade for the proper depth of cut in order to effectively uncover and remove the buried mines.
