The Forebody Aero columns are set up based on the "Fin Alone" table from Aero Predictions (Finner) aero coefficients as follows
- Mach = Corresponds to the Mach column.
- CD_Nose = Corresponds to CD_F1 (Fin 1) in our case or however many fins are placed on the nose or despun section. The total drag contribution is critical if using a bearing friction table which utilizes the change in bearing friction due to axial load. The user should be aware that the total drag of the despun section should be used. The PRODAS Aero Predictor can be used to model the nose portion alone to predict total drag. If a radial load table is not used this is not as critical.
- CNa_Nose = CNa_F1 If only the canards are being deflected. If the entire nose is being deflected the user will have to adjust this coefficient to recreate that lift performance.
- CPN_ Nose= CPN_F1 Is the center of pressure of the fin from the nose if only the canards are being deflected. If the entire nose is being deflected the user will have to adjust this coefficient to recreate that center of pressure location.
- Clp_Nose = Clp_F1 The clp of the fin should override the clp of just the unspun section (skin friction)
- Cldd_Nose = Cld_F1 * Fin Cant is the total roll torque generated by the roll surface of the nose (Please note in this case the cldd shown is for a 1 degree fin cant and should not be changed. This value will be manipulated once we get into the actual 7 DOF simulation. Please leave this value as shown,)
- Clp_Nose (Negative spin) = Clp_F1 (Roll damping in reverse spin direction)
For now we will leave the last three columns as zeros. They are defined as follows.
- CPN Radial= Radial center of pressure (Relative to Axis of rotation)
- Cya_c= Out of plane side force coefficient
- CPy_c = Out of plane center of pressure
