% Compute the surface area and center of mass of an airship gondola. Assume a rectangular shaped gondola hanging from hull. All lengths are dimensionless. Axial lengths (x) are measured back from the nose. The radial length (z) is measured out from the hull center-line. -------------------------------------------------------------------------- Form: [Sg, xGonCM, zGonCM] = GondolaGeometry( a1, a2, b, xGonA, xGonB, zGon ); -------------------------------------------------------------------------- ------ Inputs ------ a1 (1,1) Semi-major axis of front ellipsoid a2 (1,1) Semi-major axis of rear ellipsoid b (1,1) Semi-minor axis of each ellipsoid [m] xGonA (1,1) Leading-edge of gondola / hull length xGonB (1,1) Trailing-edge of gondola / hull length zGonB (1,1) Bottom edge of gondola / hull radius ------- Outputs ------- Sg (1,1) Cross-sectional area of gondola xGonCM (1,1) Cross-sectional area of gondola zGonCM (1,1) Cross-sectional area of gondola --------------------------------------------------------------------------
