Re: draw, thrust, and components

I now consider my thruster design finished.
There could always be more things to test and improve, but I am pretty satisfied at this point.
The blades in the pictures below was the best out of all the 11+ propellers I made. And there is no hiding that they are greatly influenced by the BlueRobotics T100 Thruster.
They performed slightly better then the other designs I had, but some others came really close.
Numbers were fluctuating as the thruster still managed to suck in air.
Running at 12v, the average numbers are:
Optimal direction, Forward (When the water is sucked from the propeller side and over the motor.):
1A = 0,5kg - 1,1lb - 17,6oz
2A = 0,8kg - 1,76lb - 28,2oz
3A = 1kg - 2,2lb - 35,3oz
4A = 1,3kg - 2,8lb - 45,8oz
5A = 1,5kg - 3,3lb - 53oz
7A = 1,8kg - 3,9lb - 63,5oz
8A = 2kg - 4,4lb - 70,5oz
10A = 2,3kg - 5lb - 81oz
11A = 2,5kg - 5,5lb - 88oz
13A = 2,65kg - 5,8lb - 93,5oz
19A = 3,3kg - 7,3lb - 116oz
Reverse:
1A = 0,45kg - 1lb - 16oz
2A = 0,6kg - 1,3lb - 21oz
3A = 0,9kg - 2lb - 32oz
5A = 1,3kg - 2,8lb - 45,8oz
10A = 2kg - 4,4lb - 70,5oz
19A = 2,9kg - 6,4lb - 102oz
