A body and any occupant of a land vehicle (10) is protected against effects of a landmine explosion, by conducting shock waves laterally outwardly by means of one or more shock wave guide members (16, 18) of a material having high acoustic velocity, and located proximate a ground engaging element (12) of the vehicle. The material may be glass, ceramic or the like having an acoustic velocity of about 6000 m/sec or more, i.e. higher than other materials of other components of the land vehicle. Shock waves encounter less resistance in high-acoustic velocity materials and are thus conducted laterally outwardly, i.e. away from the body. The shock wave guide members may be located immediately above bottom runs of tracks (12) and annularly within wells of bogey wheels (14) of track vehicles; and annularly around hubs or within tyres of wheels of wheeled vehicles.
A method of protecting a body or hull and any occupant of a land vehicle movable along a substrate on ground engaging elements against the effects of a landmine explosion, including conducting shock waves generated by the landmine explosion laterally outwardly by means of a shock wave guide member comprising a plurality of oriented laminates of a material having a relatively high acoustic speed and located proximate a ground engaging element of the vehicle, the laminates being oriented to extend laterally outwardly.
A land vehicle movable along a substrate on ground engaging elements, which land vehicle is adapted or converted to protect its body or hull and any occupant against the effects of a landmine explosion, the land vehicle comprising a plurality of shock wave guide members proximate ground engaging elements of the land vehicle,
A ground engaging element for a land vehicle in combination with a shock wave guide member of a material having an acoustic speed of higher than about 6000 m/sec, the guide member being locatable proximate a ground engaging surface of the ground engaging element and comprising a plurality of laminates oriented to conduct shock waves laterally outwardly in use.
