Patent ID: 8919691

Claim:
A lifesaving vehicle comprising a hollow body, which body, comprises an upper part and a lower part and forms an internal passenger compartment, whereby the body comprises a stabilising arrangement with a float chamber that, stabilises the vehicle when it is in water, a telescopic arrangement arranged centrally in the body and extending vertically through the body and comprising an internal substantially cylindrical cover formed from substantially cylindrical tubes that are inserted telescopically one inside the other, a stabilisation system arranged at the lower part of the body and comprising a substantially disc-shaped unit that extends radially out from the vertical axis of the vehicle, and which stabilisation system can be displaced in a vertical direction downwards from the lower part through activation of the telescopic arrangement, the vehicle, in order for it to travel not only over land but also in water, comprising: a first and a second rotor mounted for rotation around a first and a second axis respectively in opposite directions of rotation, of which one rotor is arranged extending out from the upper part of the vehicle while the second rotor is arranged extending out from the lower part of the vehicle, whereby the first rotor comprises a set of rotor blades ( 52 ) that extend in a first plane of blades and the second rotor comprises a number of rotor blades that extend in a second plane of blades, a motor supported by the vehicle with its associated transmission, by means of which the said first and second rotors are arranged for rotation and the generation of vertical lifting power in a medium that surrounds the vehicle, which medium may be constituted by water or air, a pair of propulsion units that are mounted on diametrically opposite sides of the vehicle for horizontal propulsion of the vehicle and for the balancing of a torque that is produced by one of the rotors, in particular the first rotor, at least one stabilisation fin that is arranged extending radially out from the outer periphery of the vehicle, and which stabilisation fin is equipped with side rudders and a height rudder for manoeuvring the vehicle through the influence of flows of medium through which the vehicle passes.
