A coaxial propeller, also known as a contra-rotating propeller, is a type of propeller configuration where two propellers are mounted on the same axis but rotate in opposite directions. This design is used in various applications, including aircraft, marine vessels, and drones. Here are some key points about coaxial propellers: ### Advantages: 1. **Improved Efficiency**: By counteracting the rotational flow of the first propeller, the second propeller can recover some of the energy lost to the r
