Hello,

Being currently in engineering school, I have to carry out a project on the design of a tethered balloon system which, in addition to producing electricity from the wind, would be able to use solar energy. I was wondering if anyone would know where I could find information on the legislation to which such a balloon would be subjected? Because it is not yet used, I can't find anything on the net.

If anyone has any ideas, I'm interested ...
Thank you

The danger is the cable, a trap for air traffic.

Maybe see with the DGAC?

In any case the idea of ​​a tethered balloon in the wind leaves me very very skeptical ... even more.

Can you elaborate on your concept?

In Belgium, for the slightest release of advertising balloons (yes, small balloons with a card to return), an authorization from the Régie des Voies Aériennes is required and subject to regulations: the time of release must be very precise.

Telephone the administration of the nearest airport: they can direct you.

This idea of ​​a kite wind turbine seems to me frankly unrealistic for a lot of reasons, but unless you know the planes, do not qualify an iron fighter plane: it flies very well with the engine off: finesse of the same order than a passenger plane, but it is a fact that the optimal gliding speed is relatively high ... when with commercial planes, a 747 or an A380 are excellent gliders contrary to what one might think, always at fairly high speeds of the order of 400-450km / h ...
As for ITER, if you are not a doctor in nuclear physics, beware of judging what you do not know ... understanding the structure of matter is absolutely essential for the technologies of tomorrow ... : Evil:

The DGAC (which I know well ...) will say NO straightforwardly, it is absolutely certain because the risks for air traffic are far too great beyond 1000m, not counting the risks in the event of a crash of the installation. .

Nice company that you encourage. An ordinary citizen does not have the right to pass judgment on his environment. Well done! continue on this path.

Raymon, if you are not a humanities doctor, avoid passing judgment on the concentration camps

All the more reason to find out about regulations. What is the point of having a good idea if it is inapplicable? Perhaps it is applicable in certain countries, in this case, it is necessary to negotiate to determine test flight slots.
And first ask the question: admitting that it is allowed in a deserted place, is it economically viable?

Air regulations risk indeed causing concern for all these projects, even if they are potentially great (up to 95% stability of air currents at altitude).

another problem, and not the least, is the risk of a cable device several hundreds of meters being lowered to the ground! A substantial security perimeter is necessary, even if the risk is low (the device must lose its lift).

Odrey, if you go on a mixed solar wind device, I don't see anything more than a kite-surf ride because you need a minimum of surface to recover solar energy, the magnus device presented by Christophe is therefore not wide enough, and in rotation, it halves the directly lit area ...

The kite-surf rides are either like the one presented on this thread (back and forth vertical by modification of the lift) ... or like other German proposals, with several rotary sails (lever arm up to 1 km!).

There is also perhaps the solution of the drone balloon? :)

A large airship, very large, very flat ... climbs very high ... more use of wind other than for traveling, but autonomous solar recharging, then return to earth to take empty batteries! Candidates?

In France, deserted places there simply are none, either from an aeronautical point of view or from the point of view of inhabitants ... there is only one area in France, apart from the Hautes Alpes with high altitude access window prohibited for commercial flights which is reserved for visual flight (gliders for wave flights), and again it can be closed overnight ...
The only compatible countries would be those with huge deserts, which are much easier to use for solar production ...
