Abstract:
PROBLEM TO BE SOLVED: To provide an unmanned lifesaving aircraft hardly impacted by the wind and capable of flying at high speed.SOLUTION: An unmanned lifesaving aircraft comprises a body part including an ellipse ring (4), a surface of which is covered with a covering material (5), and formed as a hollow ellipsoidal shape with (a body height)<(a body lateral width). A rear compressor (21) and a front compressor (11) are fixed to the left side and the right side of a keel material (1), respectively. Two open/close valves are disposed in the rear compressor, in which one of the valves is connected with a propelling injection tube (213) extending rear-ward, while the other one of the valves is connected with a rear-downward directed injection tube (212) extending vertically downward. Two open/close valves for discharging air are also disposed in the front compressor, in which, one of the valves is connected with a front-downward directed injection tube (112) extending vertically downward, while the other one of the valves is connected with a lateral injection tube (111) extending in a horizontal lateral direction perpendicular to the keel material. The respective compressors are driven by electric motors, and a motion of the aircraft is operated by opening/closing operation of valves disposed in the compressors.SELECTED DRAWING: Figure 1
