Wing Design Day 4

Aileron deflection revisions

After posting an update to the new aileron design on the Homebuilt Airplanes forum, someone replied that the “cupping” of the half rib to the leading edge of the aileron would interfere with its deflection. To fix this, a circular pattern was used to simulate typical aileron deflection and subtract exactly what is necessary from the half rib. Ollie also did some more research into the double U bracket hinge design and asked the forum what material was recommended for such a bracket and how corrosion should be prevented. They said that our aircraft likely won’t be around long enough for corrosion to be an issue but we should make the brackets out of steel (not stainless steel to avoid galvanic corrosion) to ensure they maintain their shape after many cycles. Finally, Ollie designed the trailing edge of the ailerons which is simply a 0.016” thin sheet of 2024 T3 aluminum sheet bent around the trailing edge of the aileron ribs.
