When talking about drones, many people will think of the DJI brand. Indeed, DJI is currently the leading company in the field of civilian drones in the world. There are many categories of drones, among which the type that uses rotating blades to provide lift is the most widely used type among civilian drones. So do you know how many types of drone blades there are? Do you know about carbon fiber drone blades?
4 common types of drone blades, from wood to carbon fiber
1. Wooden propeller: Wooden propeller is a propeller material that has been used since the invention of aircraft, whether it is a drone or a manned aircraft. The advantages of wooden rotating blades are light weight, low cost, and easy processing. However, the manufacturing industry is more complicated, and the finished product is not high in precision and strength, and the vibration problem during flight is obvious.
2. Plastic propeller: Plastic propeller blades are an upgraded version. They are less difficult to process and lighter in weight. They can be integrally molded with equipment and have lower processing costs. However, their fatal disadvantage is that their strength is too low and they can easily break when encountering obstructions during flight. .
3. Glass fiber blades: Glass fiber was a very popular composite material 10 years ago. The characteristics of the glass fiber blades are high mechanical strength and elastic coefficient. At the same time, the processing difficulty is not high and the cost is low. The disadvantages are It is more brittle and has low wear resistance.
4. Carbon fiber blades: Carbon fiber composite materials are upgraded glass fiber composite materials. Their comprehensive performance is several grades higher. The advantages of carbon fiber drone blades are light weight, high tensile strength, and good corrosion resistance. , has a certain degree of earthquake resistance, and overall it is better to use and more durable than the previous blades. The disadvantage is that it is brittle, and it will definitely be damaged and cannot be repaired. It is difficult to process and the production cost is relatively high.
