PA612 carbon fiber reinforced nylon for industrial grade drone propeller blades

Requirements for industrial-grade rotor drone propeller blades

With the development of communication technology and material technology, UAVs have expanded from pure entertainment applications to various other fields, such as media live broadcasting, community security, electric power inspection, base station inspection, UAV water service, logistics and distribution, emergency communication and rescue, field scientific observation, agricultural plant protection, military and other various fields. The emerging field of drones has never ceased to be innovative, affinity and compatibility from the moment of its introduction. Compared with recreational UAVs, industrial-grade rotor UAVs carry more modules, such as spray seeding system on plant protection UAVs, data acquisition and processing system on water conservancy and electricity UAVs, fire-fighting delivery thermal imaging system on fire-fighting UAVs, and aerial shouting device on security UAVs, which substantially increases the overall weight of the UAVs, and puts forward higher requirements for the overall performance of the UAVs.

UAV propeller blades, as an important part of rotary wing UAV lift-off, are directly related to the flight performance of a UAV. Rotary wing UAV is to change the rotational speed of the paddle, that is, to change the pull force to make the multi-rotor fuselage produce different directions of pull force, so as to achieve the purpose of changing the attitude, so the limit pull force is an important parameter index of the propeller blade. In the case of the same motor speed, the longer the diameter of the propeller blade, the greater the pull force; the smaller the diameter, the smaller the pull force. In the case of the same diameter, pitch and motor speed, the more blades, the greater the pull force will be, and at the same time, the rotational inertia of the blade and air resistance will also be greater. However, the power consumption of multiple blades to reach the same speed as two blades will increase rapidly. Therefore, industrial-grade multi-rotor UAVs usually use one-piece or folded twin-screw propellers.

The current common naming rule for drone propeller blades is to use 4 digits plus letters, the first two digits of these models indicate the size of its diameter, such as the diameter of the propeller blade of the folding propeller 3628 is 36 inches, and the diameter of the propeller blade of the one-piece pulp 1503 is 15 inches; the last two digits indicate the recommended zui pull force of the propeller blade in KG; the model number with an L at the end of the model number is used when the propeller is rotating in a clockwise direction with the When using the model with L, the propeller rotates clockwise with the motor (top view), while with R, the propeller rotates counterclockwise with the motor (top view).

PA612 carbon fiber reinforced material is the ideal material to be used as the propeller blade of industrial-grade rotary wing UAV, which meets all the functional requirements of the product and has the following features:

1. Lower specific gravity, PA612 specific gravity 1.06, relative to PPA/Pa66 and other lower specific gravity, meet the specific gravity of carbon fiber after as low as 1.25, can significantly reduce the rotational inertia, reduce the energy consumption of the UAV, and improve the endurance;

2.PA612 has a lower water absorption rate relative to other nylon, which can ensure that the UAV propeller blade maintains excellent strength and stability in various environments;

3. PA612 has good tensile strength and impact resistance, and has high mechanical strength after adding carbon fiber, which keeps it smooth in the case of increasing the extreme pulling force of the propeller blade;

4. The proportion of carbon fiber varies from 30% to 50%, which can be applied to one-piece pulp of 9-20 inches in diameter and folding paddle of 10-40 inches in diameter;

5. According to customer's requirement, it can be customized with black glossy or carbon fiber black and grey, the surface can be glossy and frosted surface, no floating fiber and no fiber pattern;
