Path: Airships/Simulation
% Airship propeller model.
The airship has two counter-rotating propellers mounted to opposite
sides of the gondola. They are nominally aligned in the +x direction.
Each propeller is assumed to have a maximum thrust capability of
"d.thrustMax".
The thrust may be directed by simultaneously rotating each propeller
about the y-axis through the angle "control.mu".
The total thrust may be controlled via "control.throttle", which
linearly scales the magnitude.
The output is a data structure that contains the forces and torques on
the airship due to the propeller thrust.
