% Airship Model #1
Contains the geometric and mass properties for a specific airship model.
This script may be used as a template to create variations of this model.
The following geometric configuration is assumed:
* double-ellipsoid hull with circular cross-section
* two horizontal tail-fins (identical, symmetric, based on NACA 1412)
* two vertical tail-fins (identical, symmetric, based on NACA 1412)
* streamlined hanging gondola
The following design parameters are specified:
* alt operating altitude [m]
* L hull length [m]
* D hull diameter [m]
* ratio rear ellipsoid length / front ellipsoid length
* xFinA start of fin at hull / hull length (meas from nose)
* xFinB start of fin taper / hull length (meas from nose)
* xFinC end of fin / hull length (meas from nose)
* yzFinI inboard fin width / hull radius (meas from center axis)
* yzFinO outboard fin width / hull radius (meas from center axis)
* xGonA gondola leading edge / hull length (meas from nose)
* xGonB gondola trailing edge / hull length (meas from nose)
* zGon bottom of gondola / hull radius (meas from center axis)
* rhoFab area density of skin fabric [kg/m^2]
* mP payload mass [kg]
* thrustMax maximum thrust capability [N]
* xProp x-location of propellers / hull length (meas from nose)
* zProp z-location of propellers / hull radius (meas from center axis)
x-distances for fins, gondola and props are dimensionless (with L)
y,z-distances for fins, gondola and props are dimensionless (with D/2)
