- The fin core, fin roots, and fin fillets have no stiffness and bare no load
- The carbon fiber plies are .010 in thick
- The composite matrix has no compressive strength
Load Estimation
The fin's weakest axis is reacting moments around the root of the fin. To size the carbon fiber tip to tip layup for this case we need to estimate the moment around the root of the fin. From aerodynamics the force on the fin is
