The propulsion shell is mainly used to install the propulsion system of aerial vehicles such as drones. The propulsion shell is a critical component that protects and supports the internal structure and components of the propulsion system, ensuring its proper operation. The propulsion shell is typically made of high-strength, lightweight aluminum alloy materials to meet the weight and strength requirements of the drone during high-speed movement and flight. Additionally, the propulsion shell has excellent corrosion resistance and durability to ensure proper operation of the drone in complex environments.The propulsion shell is an important component used on aerial vehicles such as drones. It is typically made of high-strength, lightweight aluminum alloy materials (such as A5083), which provide excellent corrosion resistance and durability. The design of the propulsion shell typically features a streamlined shape to reduce drag and improve flight efficiency, and its surface is usually treated to provide a certain degree of corrosion resistance and wear resistance. Machining the propulsion shell is difficult and requires the use of advanced CNC machining centers and auxiliary equipment to ensure machining accuracy and surface quality.
