Testing axial loads on a standard 10mm rod end, as I use it on my folding wing aircraft.I remind you that the load that this rod end must withstand is approximately 1/5 of the total load on the wing, i.e. 120kg x 1/5 = 24kg Load: 36kg which corresponds to 1.5g Load: 156kg or 6.5gLire la suite « Axial load on a rod end »

Here is what I had suggested: But some people tell me that the fixing of the strut at the bottom is not secure enough with a rod end in this position (at the top it is OK) . Someone tells me that this rod end should be able to withstand a pull of 1350kg! SoLire la suite « Attachment of the wings (2) »

Front attachment of the wing to the fuselage, with a 10mm rod end Suggestion of fixings to the spars:

On my 1/5th scale model the wings were held by small rod ends to allow their folding.

The fuselage could be reduced to 1m wide, for a better aerodynamics, with bubble doors to keep 1.10m at the elbows. (Like Zenith STOL 701)

Plans of a two-seater, electric or piston engine, with my folding wings system. Anyone want to build it? The horonzital stab area could be slightly increased. With that design we have 15% of the wing area. + the plates at each tips which increase the efficiency See the single seat model: https://wordpress.com/post/avionaailespliantes.fr/320https://www.youtube.com/watch?v=C5TDlnbLw1U My email: fabreflyingcar@orange.fr

My little plane is now towed by the tail. This makes it more stable on the road. It rests on its tail, on a small wheel, when the wings are folded and it stays on a tricycle landing gear when the wings are open.

Mon petit avion est maintenant remorqué par la queue. Ainsi il est plus stable sur la route. Il repose sur sa queue, sur une roulette, quand les ailes sont repliées et il reste en train tricycle quand les ailes sont ouvertes Vidéo: Rappel du principe de pliage des ailes avec des rotules: Ci dessous laLire la suite « Avion électrique à ailes pliantes: Modifications »

In this position the angle of attack of the wings is 7° from the ground

Dans cette position l’angle d’incidence des ailes est de 7° par rapport au sol.
