Aircraft having supporting structure and gas-filled envelope
An aircraft has a supporting structure and a shell that can be filled with a gas and which is tensioned by the supporting structure. The supporting structure includes a plurality of rod or tube-shaped sections which define a circular, oval or polygonal main clamping plane for the shell.
1. An aircraft comprising:
a supporting structure; and
an envelope that is tensioned by the supporting structure and can be filled with a gas,
wherein the supporting structure comprises a plurality of rod or tube portions which define a circular, oval or polygonal main tension plane for the envelope, and
wherein the envelope comprises two envelope halves that are configured to be interconnected by a first zipper and a second zipper,
wherein when at least one of the first zipper and the second zipper are opened, the two envelope halves are securely interconnected at a connection region at an end region of the first zipper and the second zipper and can be folded apart in a shell-like manner, and
wherein when the first zipper and the second zipper are closed, a tunnel is formed between the first zipper and the second zipper, which tunnel receives the rod or tube portions of the supporting structure defining the main tension plane of the envelope.
2. The aircraft according to claim 1 , wherein the end parts of the rod or tube portions are detachably fitted together in pairs by means of a plurality of sleeve elements, each of said plurality of sleeve elements comprising at least two sleeve parts.
3. The aircraft according to claim 2 , wherein a portion of each sleeve element of the plurality of sleeve elements comprises an additional sleeve part for incorporating an axis of rotation of a wing element that can be adjusted about the axis of rotation and protrudes from an outer periphery of the sleeve element.
4. The aircraft according to claim 2 , further comprising a securing sleeve arranged on a respective rod or tube portion of the plurality of rod or tube portions and overlapping a respective sleeve part of the at least two sleeve parts.
5. The aircraft according to claim 1 wherein the plurality of rod or tube portions comprise at least two intersecting rod or tube portions configured to stabilize the main tension plane, and the aircraft further comprises a frame part arranged in an intersecting region of the at least two intersecting rod or tube portions, which frame part comprises openings for the at least two intersecting rod or tube portions.
6. The aircraft according to claim 5 , wherein a blower is arranged on the frame part, which blower applies compressed air to the interior of the envelope.
7. The aircraft according to claim 5 , wherein functional components are arranged on the frame part.
8. The aircraft according to claim 1 , wherein the plurality of rod or tube portions comprise a carbon fiber material.
9. The aircraft according to claim 1 , wherein the envelope is made of an air-impermeable, tear-resistant synthetic fabric material.
10. The aircraft according to claim 1 , wherein a communication antenna is incorporated into the material of the envelope or is deposited or rolled thereon.
11. An assembly comprising a plurality of aircraft according to claim 1 , wherein the plurality of aircraft are coupled to one another.
12. The assembly according to claim 11 , wherein the plurality of aircraft are coupled to one another by ropes, cables or a planar solar element.
13. An assembly comprising the aircraft according to claim 1 and ropes or cables anchoring the aircraft to the ground, in order to monitor a limited region by means of optical and/or electromagnetic devices arranged on the aircraft.
