What are the common faults of drone blades
During the operation of drone blades, various faults may occur. The following
are some common faults of drone blades:
First, blade damage
Paddle surface defect
Cause: Due to external force collisions (such as hitting trees, buildings, etc.) or other reasons, cracks, notches and other damages occur on the paddle surface.
Impact: Defects in the rotor surface can reduce the lift of the drone and may cause changes in the center of mass of the drone's rotor, generating significant vibrations and affecting flight stability. In severe cases, it may even lead to a "propeller" accident (the high-speed rotating rotor breaks and flies out), causing harm to people around.
Blade deformation
The reason is that the blades have deformed due to long-term use or improper storage.
Impact: The deformation of the rotor blades will also affect the lift and flight stability of the unmanned aerial vehicle.
Second, the blades cannot rotate
Motor problem:
Cause: Internal faults of the motor (such as winding damage, bearing wear, etc.) or motor circuit breakage.
Impact: It causes the blades to be unable to rotate, and the drone to be unable to take off or fly.
Transmission system failure
Reasons: Gear damage, disconnection from the motor or breakage of the drive shaft, etc.
Impact: The blades cannot obtain power and cannot rotate.
Third, the blades are installed incorrectly
Confusion of blade types:
Reason: When replacing the blades, the forward-rotating (CW) and counter-rotating (CCW) blades were not correctly distinguished.
Impact: It may cause abnormal attitude of the drone after takeoff, or even prevent it from taking off.
Not installed firmly
Reason: The blades were not installed firmly and became loose or fell off during flight.
Impact: The detachment of the rotor blades may cause the drone to lose control or even crash.
Fourth, the blades age
Reason: Long-term use or improper storage has led to the aging of the blade material.
Impact: The performance of the blades declines, such as reduced lift and increased vibration, which affects the flight stability and safety of the unmanned aerial vehicle.
Fifth, attachments on the surface of the blades
Reason: During flight, the blades may adsorb dust, sand and other debris.
Impact: Attachments will increase the weight of the blades, reduce lift, and may alter the aerodynamic performance of the blades, affecting flight stability.
Fault handling method
Defect or deformation of the paddle surface
Treatment: Replace the blades with new ones.
Prevention: Check the condition of the blades before flying to avoid flying in harsh environments.
The blades cannot rotate.
Handling: Inspect the motor and transmission system, and replace the damaged components.
Prevention: Regularly maintain the drone and avoid prolonged high-load use.
Blade installation error:
Handling: Reinstall the blades to ensure they are of the correct type and securely installed.
Prevention: When replacing the blades, read the manual carefully and follow the instructions.
Blade aging
Treatment: Replace the blades with new ones.
Prevention: Avoid storing drones in harsh environments and regularly check the condition of the blades.
Adherents on the blade surface:
Treatment: Clean the surface of the blades after flight to remove adherents.
Prevention: Check the condition of the blades before flying and avoid flying in environments with a lot of dust, sand and other debris.
In summary, common faults of drone blades include blade damage, inability of blades to rotate, incorrect installation of blades, aging of blades, and attachments on the surface of blades, etc. To ensure the flight safety and stability of the unmanned aerial vehicle (UAV), users should regularly inspect the condition of the blades, replace damaged blades in a timely manner, and avoid flying and storing the UAV in harsh environments.
