Abstract: A turret drive assembly fixedly secured to a turret causes rotation of the turret via rotation of an aiming wheel fixed to the turret drive assembly. The turret drive assembly comprises a drive mechanism which is operatively coupled to an aiming wheel and a first sprocket wheel so that rotation of the aiming wheel rotates the first sprocket wheel. Rotation of the first sprocket wheel rotates a second sprocket wheel which rotates a drive gear which is engaged with a fixed ring gear secured to a vehicle. Rotation of the drive gear, when engaged with the ring gear, rotates the turret. The drive gear and ring gear may be disengaged from one another and held in such a position.

Abstract: A system for protecting a passenger compartment of a vehicle from forces arising from a mine activated by a wheel. The system (28) includes an underbody protective plate structure (46) covering areas of a forward portion of the passenger compartment in which the lower legs and feet of an occupant are located. The system (28) further includes a shield structure (44) fabricated on the protective plate structure (46) in front of lower-forward walls (36,38) of the forward portion (32). In addition, reinforcing plates (48,50) extend adjacent the side walls of the forward portion (32) and are connected to the protective plate structure (46).

Abstract: A land vehicle has a floor with upper and lower surfaces. Fibrous material is bonded to the upper surface of the floor, and a ballistic panel/blast shield is disposed below the floor and is spaced from the lower surface of the floor to create an air gap between the panel and floor. Mechanical fasteners secure the panel to the vehicle. Resilient material is disposed between the vehicle and the panel at the fasteners. The panel, air gap, resilient material and flooring provide resistance to blast pressure. The flooring and fibrous material trap flying shrapnell fragments.
