ThrustPropeller:

Path: AC/ACEngine

% Compute propeller thrust. 

   There are two options, 'power' or 'thrust'. With power the thrust is
   t = propeller efficiency*power/velocity

   If it is thrust the it is

     thrust = cT*rho*N^2*d^4

   where the constants are defined below.

   Type ThrustPropeller for a demo.
   Since version 5.
