Hi. Thank you for your reply. I am never going to build any airplane (well never say never - I should say, it's completely orthogonal to any of my plans). I have a mathematical (-type, obviously it's physics and aerodynamics) proof that it should be possible, so that the person reviewing it would be quite easily assured that what I propose is theoretically possible - but then so is a space elevator. I do not have the level of qualifications necessary to show that it is actually easily possible at airplane scales and with present materials. If I built a prototype (doing so is not in my plans) then it would be at a very small scale and I personally don't know how to do the calculations to see how it applies to larger scales. In other words, if I had the prototype flying around me right now it wouldn't help convince me that it's possible and plausible. Further calculations are necessary and only an aviation company (or an aviation engineer) is able to perform those. Are you an aviation engineer? Do you know someone who could spend a few minutes on this case? I will need a small NDA but I am not very concerned of IP theft, just the formalities; the assurance can be verbal via email. Unfortunately the medium would have to be via email as public disclosure prevents patenting and I don't know at what point (if ever) I would get to that stage. Let me know if you or someone you can put me in touch with could look at this briefly. Your profile here does not list an email. Thank you for your assistance.
