Efficient Propeller for Drones

This invention is a variable pitch propeller suitable for drones and electric vertical take-off and landing vehicles that can improve propulsion efficiency at both low and high speeds. By using a counterweight, it allows for autonomous adjustment of the blade's pitch angle and achieves a design that is inexpensive and easy to assemble and adjust. This is expected to reduce operational costs for aircraft and enable more companies and individuals to utilize drones and electric motors.

• Autonomous pitch angle adjustment using a counterweight
• Inexpensive and easy to assemble and adjust design
• Structure that maintains the balance of the propeller

Conventional variable pitch propellers are complex and expensive, making widespread adoption difficult. In particular, small aircraft such as drones and electric vertical take-off and landing vehicles require efficient propulsion, but traditional technologies could not meet this demand. Additionally, issues with assembly and adjustment made manufacturing costs high. This has hindered many companies and individuals from utilizing drones and electric motors.

This invention autonomously adjusts the pitch angle of the blades using a counterweight, achieving a design that is inexpensive and easy to assemble and adjust. This improves the complex and expensive structure of conventional variable pitch propellers, allowing for widespread adoption. Moreover, by maintaining the balance of the propeller, it achieves efficient propulsion and improves propulsion efficiency at both low and high speeds. This will reduce operational costs for aircraft and enable more companies and individuals to utilize drones and electric motors.
