METHOD OF ENHANCING DAMAGE RESISTANCE OF AMPHIBIAN VEHICLE Russian patent published in 2006 - IPC B60F3/00 F41H7/00 

FIELD: war materiel; amphibian vehicles.

SUBSTANCE: proposed method includes delivery of exhaust gases of power plant to cavities of casings mounted on the outside of vehicle by means of controllable intake and exhaust valves. In case of rectilinear motion of vehicle, delivery of exhaust gases to cavities of port and starboard casings is performed smoothly and in case of turn delivery of exhaust gases is regulated in such way that pressure in cavities on side of turn and on opposite side decreases or increases in proportion to square of speed of vehicle and inversely relative to radius of its turn.

EFFECT: enhanced efficiency.
