This project was the design of a spring steel landing gear for the tandem tractor gyroplane that I was concurrently developing at the time. The main landing gear were modified Cessna 140 landing gear legs. I used iterative Finite Element Analysis to tailor the leg spring stiffness to produce the desired deflection at max landing weight and landing descent rates. I milled the width of the gear legs down to the specific analyzed dimensions. The gear was sized per configuration applicable FAR23 load cases.
