ABSTRACT:
A center mounted power train configuration for a high water speed tracked amphibious vehicle which mounts the engine above the waterjet inlet plenum to shorten the power train length, so as to allow the vehicle length and weight to be optimized for land and water mobility. The short power train length provides for use of alternate longer components which may be required to obtain adequate power and thrust. Center mounting the power train reduces air ingestion into the waterjets and maximizes the sharing of support structure to lighten the vehicle. Center mounting of the power train also optimizes efficiency by using one propulsion gearbox to transfer power and improves access to components for repair or replacement. The power train arrangement features a rearward center of gravity for enhanced land and water mobility and provides space for locating personnel, for mission equipment and for access to floor level suspension components. Centermounting of the power train provides straight unobstructed aisleways on each side of the vehicle for personnel egress and ingress.
