Patent ID: 8905164

Claim:
A vehicle having a sacrificial buoyancy structure for attenuating damage to selected portions of the vehicle due to blast force from an under-vehicle explosion, the vehicle comprising: a vehicle body; a primary hull of the vehicle; connector plates disposed along sides of the primary hull; track assemblies mounted to the connector plates; gussets attached to the connector plates; a sacrificial connection of the gussets to the primary hull such that a sufficient amount of the blast force detaches the gussets, connector plates and track assemblies from the primary hull, whereby the gussets, connector plates and track assemblies absorb a portion of the blast force; cross rods disposed between the connector plates and affixed thereto; and a buoyancy hull beneath the primary hull attached to the cross members, the connector plates and the primary hull such that the buoyancy hull, the connector plates and the primary hull form an enclosed compartment.
