  • Patent number: 9021933
    Abstract: A vehicle capable of dissipating explosion force and energy caused due to explosion of an explosive including but not limiting to mine and/or grenade under the vehicle, below the wheels, and/or on side of the vehicle with minimal effect on the personnel and material inside the vehicle, and thereby, capable of providing safety and stability to the personnel and material inside the vehicle even if vehicle is made from armor of low thickness is provided, wherein blast air force and energy is directed through one or more passages (7, 8, 9) running from one side of the vehicle to opposite side of the vehicle in a manner that blast air force and energy generated on explosion dissipates from side of the explosion through said passages to another side of the vehicle. In one embodiment, the vehicle further comprises a periscope like structure (21) and corrugated sheet (31, 32, 33).
