Abstract

One or more sound cannons (2) are supplied with energy from a special electrical generator fitted on a controllable exploding ramp (1) which has at least three freedom degrees of mobility. Both the ramp with the cannons and the electrical generator can be fitted on different types of vehicles. The focussed sound shock waves have sufficiently high pressure and high front speed that they can explode mines located on the ground or hidden underground to a depth of several centimetres. The ground is scanned in a specific pattern. The achievement of the pattern, the effect and firing frequency of the cannons and the speed of the vehicles are important parameters which control the target seeking and explosive results.

Description

lx) lJ\ 510 971 FIGUR 1 och 2 visar användning av ett batteri av ljudkanoner anbragda på olika typer av landgående fordon som till exempel bil eller fordon med larvfötter. 1x) 1J and 510 971 FIGURES 1 and 2 show the use of a battery of sound cannons mounted on different types of land-going vehicles such as cars or vehicles with caterpillar feet.

F IGUR 3 och 4 visar användning av ett batteri av ljudkanoner anbragda på lufiburna fordon som till exempel svävare eller helikopter.FIGURES 3 and 4 show the use of a battery of sound cannons mounted on airborne vehicles such as hovercraft or helicopters.

Fordon enligt FIGUR 1, 2, 3 och 4 har en avfymingsramp (1) av lämplig konstruktion anpassad till fordonets egenskaper.Vehicles according to FIGURES 1, 2, 3 and 4 have a firing ramp (1) of suitable construction adapted to the characteristics of the vehicle.

På rampen är en eller flera ljudkanoner (2) anbragda. Rampen har full styrbarhet i minst tre frihetsgrader, vilket ger tillfredsställande möjlighet till målsökning som kan styras både manuellt och automatiskt.One or fl your sound cannons (2) are mounted on the ramp. The ramp has full controllability in at least three degrees of freedom, which provides a satisfactory opportunity for target searching that can be controlled both manually and automatically.

En eller flera ljudkanoner kan beskjuta marken på ett systemreglerat sätt med fokuserade ljudchockvågor som har tillräckligt stort tryck och tillräckligt hög fronthastighet för att kunna utlösa minor som ligger på eller är nergrävda i marken på några centimeters dj up.One or more sound cannons can fire the ground in a system-controlled manner with focused sound shock waves that have sufficient pressure and high enough front speed to be able to trigger mines that are on or buried in the ground at a few centimeters deep.

Marken beskjuts enligt ett visst rutrnönster. Mönstrets upplösning, kanonemas effekt, avfymingsfrekvens och fordonets hastighet är viktiga parametrar som styr kanonemas målsökning och avfyrning. Samverkan mellan dessa parametrar avgör minröj ningens noggrannhet.The ground is shelled according to a certain grid pattern. The resolution of the pattern, the effect of the cannons, the firing frequency and the speed of the vehicle are important parameters that control the aiming and firing of the cannons. The interaction between these parameters determines the accuracy of the demining.

Fordonet befinner sig några tiotals meter från den beskjutna marken.The vehicle is located a few tens of meters from the shelled ground.

Den har ingen direkt kontakt med minoma och löper därför minimal risk att skadas av eventuella explosioner. Kanonemas effekt bör även klara mindre växtlighet på marken eller vattensamlingar av ett mindre djup.It has no direct contact with minoma and therefore runs a minimal risk of being damaged by possible explosions. The effect of the cannons should also cope with less vegetation on the ground or water bodies of a smaller depth.

Den fulla styrbarheten hos avfymingsrampen garanterar hela spektrumet av avfymingshöjder och vinklar vilket möjliggör beskjutning av branta backar och djupa ravíner utan att själva fordonet måste förflytta sig dit.The full controllability of the firing ramp guarantees the full range of firing heights and angles, which enables shelling of steep slopes and deep ravines without the vehicle itself having to move there.

Då även luftbuma fordon kan bära avfymingsramp finns det många olika varianter på hur marken kan minröjas. Metoden kan även appliceras till havs och på så sätt kan marina minor flytande nära vattenytan röjas.Since even air-buoyed vehicles can carry firing ramps, there are many different variants of how the ground can be cleared. The method can also be applied at sea and in this way marine mines fl surface close to the water surface can be cleared.
