The unmanned vehicle variable surface pressure device 1 includes a rotating four-blade, fixed pitch rotor 12 which is powered by a motor. The motor itself is fixed to a top plate 2 that has a side wall 8 and a flexible skirt 9. The device uses an electric motor or internal combustion engine or gas turbine to rotate the rotor 12. The rotor 12 has four fixed pitch tapered blades at ninety degrees to each other, each with a flat leading face 17 and trailing face 19. The device may house batteries to power the motor or a fuel tank for the internal combustion engine or gas turbine. Alternatively, the electric motor may be fitted to an external power supply. The device is fitted to unmanned vehicles and is used to increase the slopes and gradients that vertical takeÂoff and landing unmanned aerial vehicles can land and take-off from, to enable unmanned wall climbing vehicles to operate on more slippery and inverted surfaces, to increase the stability and mobility of unmanned ground vehicles and permit surface crawling operation of unmanned underwater vehicles. |
