Ready to public release

Fixed default propellers gear ratio and gearbox losses. Completed README. Binaries not available yet. User must edit the input section of the main file to tailor the program to his/her propellers.

Gearbox feature

Code includes annotations on propeller thrust data and gear ratio, accounting for mechanical losses (provided by the user). Also, single point data are correctly plotted.

Version 6

Code compacted with functions, now it should be easier to add other charts or features.

Version 5

It is possible to plot any number of propeller conditions. These plot lines have been thickened.

Version 4

Version 4. As pre-process, RPM are scaled to get (almost) the same order of magnitude of other variables. This provides smoother interpolated data. Also, motor map (torque vs RPM, contour of motor efficiency) has been added.

Version 3

Version 3. Same as Version 2, but with X and Y axes swapped. Some variables have been renamed.

Version 2

Version 2. Current calculated from RPM and shaft power assigned by the user, which has only to provide the desired propeller advance ratio J, the expected shaft power in watt and the RPM.

Version 1

Version 1. Operating points manually chosen as close as possible to the available manufacturer data.
