Controllable Pitch Propeller Mechanics

In this video, John introduces the concept of a controllable pitch propeller (CPP) and explains its operation without any editing. The video covers how changing the pitch of propeller blades can control the direction of a vessel. It delves into the hydraulic actuation mechanism, explaining how fluid flow controls piston movement, which in turn adjusts the propeller blades' angle. The video also illustrates the conversion of linear motion to rotary motion, essential for propeller operation. John concludes by offering additional resources for further learning.
