Responding to an explosion local to an armoured vehicle
View Patent ↗A blast countermeasure for a vehicle, such as an armoured vehicle, is provided. The blast countermeasure comprises: at least one explosive; a detonator for detonating the explosive; and at least one reflector, located at least partially above the at least one explosive, for reflecting a shock wave generated by detonation of the at least one explosive groundwards in order to apply a groundwards force to the vehicle. The vehicle may comprise: control circuitry configured to respond to detection of an explosion local to the vehicle by activating an actuator to generate a groundwards force and cause a cabin floor of the vehicle to move groundwards.
1. An armoured vehicle, comprising:
at least one detector for detecting an explosion local to the armoured vehicle;
a cabin floor;
at least one actuator, coupled to the cabin floor, for generating a force to cause at least a portion of the cabin floor to be pulled groundwards; and
control circuitry configured to respond to detection of an explosion local to the armoured vehicle by activating the actuator to cause the cabin floor to move groundwards.
2. The armoured vehicle of claim 1 , further comprising a tractor configured to pull at least a portion of the cabin floor groundwards in response to generation of the force by the at least one actuator.
3. The armoured vehicle of claim 2 , wherein the tractor is connected to an underside of the cabin floor.
4. The armoured vehicle of claim 2 , wherein the tractor comprises at least one spring, at least one rod, at least one cable and/or at least one chain.
5. The armoured vehicle of claim 1 , wherein the at least one actuator comprises an explosively driven actuator.
6. The armoured vehicle of claim 5 , wherein the explosively driven actuator comprises multiple explosive cartridges, each explosive cartridge enabling a force to be generated to cause at least a portion of the cabin floor to be pulled groundwards on a separate occasion.
7. The armoured vehicle of claim 1 , wherein at least a portion of the cabin floor is fixedly positioned within the vehicle.
8. The armoured vehicle of claim 7 , wherein the cabin floor is configured to flex upon actuation of the at least one actuator.
9. The armoured vehicle of claim 8 , wherein the cabin floor is configured to return to its original position after generation of the groundwards force by the actuator.
10. The armoured vehicle of claim 7 , wherein the cabin floor is fixedly positioned within the vehicle along at least a portion of the periphery of the cabin floor, and the portion of the cabin floor that is pulled groundwards upon actuation of the at least one actuator is located away from the periphery of the cabin floor.
11. An apparatus, comprising:
at least one detector for detecting an explosion local to an armoured vehicle;
at least one actuator, for coupling to a cabin floor of the armoured vehicle, configured to generate a force to cause at least a portion of the cabin floor to be pulled groundwards; and
control circuitry configured to respond to detection of an explosion local to the armoured vehicle by activating the actuator to cause the cabin floor to move groundwards.
12. A method, comprising:
detecting an explosion local to an armoured vehicle; and
pulling a cabin floor of the armoured vehicle groundwards in response to detection of the explosion.
13. The apparatus of claim 11 , further comprising a tractor for pulling at least a portion of the cabin floor groundwards in response to generation of the force by the at least one actuator.
14. The apparatus of claim 13 , wherein the tractor is for connection to an underside of the cabin floor.
15. The apparatus of claim 13 , wherein the tractor comprises at least one spring, at least one rod, at least one cable and/or at least one chain.
16. The apparatus of claim 11 , wherein the at least one actuator comprises an explosively driven actuator.
17. The apparatus of claim 16 , wherein the explosively driven actuator comprises multiple explosive cartridges, each explosive cartridge enabling a force to be generated to cause at least a portion of the cabin floor to be pulled groundwards on a separate occasion.
18. The apparatus of claim 11 , wherein the cabin floor is configured to flex upon actuation of the at least one actuator.
19. The apparatus of claim 18 , wherein the cabin floor is configured to return to its original position after generation of the groundwards force by the actuator.
20. An armoured vehicle, comprising:
a blast shield located at the underside of the armoured vehicle;
at least one detector for detecting an explosion local to the armoured vehicle;
a cabin floor;
at least one actuator, coupled to the cabin floor, for generating a force to cause at least a portion of the cabin floor to move groundwards relative to the blast shield while the actuator remains coupled to the cabin floor; and
control circuitry configured to respond to detection of an explosion local to the armoured vehicle by activating the actuator to cause the cabin floor to move groundwards.
