HydrazineThruster:

Path: SC/Actuator

% Computes the thrust and fuel consumed for thrusters. 
   The thrust is dependent on the pressure of the propellant. The exhaust
   velocity is dependent on the pulsewidth, it increases from a minimum to a
   maximum.

   The data structure and default values of the properties can be found from
      p = DeviceProperties( 'hydrazine thruster' )

   Since version 8.
--------------------------------------------------------------------------
   Form:
   [thrust, dF, impulse, pulsewidth] = HydrazineThruster( d, pressure, pulsewidth, dT )
