In this video we go over some of the most important propeller concepts, some of which are misunderstood by most of people. Propeller theory is exceptionally complex, but I explain it in a simple and easy to understand way without going very deep into math and physics. Unless you are an aeronautical engineer or already know everything about propellers you can expect to go out of watching this video having a much increased understanding on the workings and limitations of airplane propellers.

Also watch this video to understand how an engine gearbox actually multiplies torque at the propeller:    • Propeller Speed Reduction TORQUE Incr...
