WebMar 11, 2024 · As i understand from the name FIXED speed means that turbine works at some fixed speed (e.g. 7 m/s) and if speed is less, it doesnt work and if speed is higher it tries to lower the RPM to match the RPM for 7 m/s. Whereas variable wind turbines can work at the range of cut in and cut out speed. http://essentialpilot.co.za/2024/02/16/constant-variable-and-fixed-pitch-propellers-what-is-the-difference/ can ping from server but not to server
