"However, to give you something to chew on I suggest you look at your
statement, ‘Velocity may not increase in proportion to torque’. I should
certainly hope not unless you have found some remarkable new facet of
aerodynamics! <smile>"
John,
If the weight was increased in proportion to torque, the rpm and velocity
would increase in proportion to the square root of torque. All forces would be
in the same proportion, everything would happen faster, but in geometric
similarity, angles would be the same. Flight trajectory would have the same
shape, but bigger, and the advance ratio would be the same. The only deviation
I can see would be due to aerodynamic scale effects, hard to estimate without
particulars.
This is similar to a glider. Increasing its weight will increase all forces
in proportion, speed and sink rate in proportion to square root and glide
angle will be unaffected, if CG is same. The force diagram is geometrically
similar, just bigger. Weight is the scale factor.
