ABSTRACT:

FIELD OF THE INVENTION
The invention relates to an aircraft having a frame and at least a rotor for providing lift for the aircraft.
SUMMARY OF THE INVENTION
Publications FI-49949, DE-2 648 504, U.S. Pat. Nos. 2, 740, 595, 4,123,018, WO-87/02004, U.S. Pat. Nos. 2,847,173 and 3,722,830 disclose various aircraft of a helicopter type. The aircraft disclosed in the publications are not versatile enough and they consume plenty of fuel.
An object of the present invention is to provide an aircraft in which the above-described disadvantages can be avoided.
The aircraft of the invention is characterized in that it provides a means for accommodation purposes, that solar cells are arranged on the aircraft for exploiting solar energy and that in connection with the rotor, means are provided for exploiting wind energy by means of the rotor.
It is an essential idea of the invention that the aircraft is adapted for moving and accommodation purposes and comprises a frame and at least a rotor connected thereto for providing lift. Solar cells are arranged on the frame and/or the rotor for exploiting solar energy and the rotor is so arranged that it enables the exploitation of wind energy. It is an idea of a preferred embodiment that the frame is convex.
It is an advantage of the invention that the aircraft, being adapted for moving and accommodation purposes, is extremely versatile. Solar energy can be exploited by means of the solar cells. When a rotor blade is so arranged that the device is also able to exploit wind energy, the amount of fuel used for flying and accommodation purposes can be considerably reduced and, most preferably, no external fuel is required. The efficiency and flying characteristics of the aircraft can be optimized by making the frame convex.
