I am working on a hinge/horn (hinged 10mm below the lower surface) assembly to be mounted on the underside of the wing TE attached beneath the LE of the aileron. These I may trade off weight for strength and get them done from billett. The assembly will include the control linkages, connecting to a bellcrank on the wing mounted attachment which transmits force from the aileron bellcrank in the wing to the actuating pushrod to the control mounted pivot/linkage assembly.
I'll have some drawings later, but my initial sketches in the configuration I envisaged, only gives me a very small amount of travel on the control horn. 20/15° deflection (Friese ailerons) controlled for equal distance throws of only 6mm by the horn.
This will mean at times there will be a pretty large moment in effect at this point, and I was wondering if since the connecting rod is going to be short, if these forces can be sufficiently dealt with by a conventional linkage system? I can see the ailerons being pretty heavy.
