% Compute the hull and fin efficiency factors for an airship. Zero dihedral is assumed. -------------------------------------------------------------------------- Form: [etaK, etaF] = FinFactors( J1, Sf, Sfh, vol ) -------------------------------------------------------------------------- ------ Inputs ------ J1 (1) One of Munk's integrals; see AirshipIntegrals.m Sf (1) Fin reference aera Sfh (1) Combined fin & hull cross-sectional area vol (1) Hull volume ------- Outputs ------- etaK (1) Hull efficiency factor (effect of fins on the hull) etaF (1) Fin efficiency factor (effect of hull on the fins) -------------------------------------------------------------------------- Reference: Khoury, Gillett, "Airship Technology", p.53 -------------------------------------------------------------------------- Copyright (c) 2003 Princeton Satellite Systems, Inc.
