Technical Notes: The Rotor Blade Flap Bending Problem—An Analytical Test Case
Abstract:There is growing interest in solving the rotary wing aeroelastic equations using finite element theories. To test or validate these finite element solutions, as well as other solution approaches such as normal modes, a numerically exact solution for the simple, uncoupled, out‐of‐plane, flap bending of a rotor blade in forward flight is provided. The analytical test case was created by defining a representative deflection and solving backwards for the forcing function that satisfied the governing fourth‐order equation.
