Fastening Elements for Drones: Transformative Technology for Future Delivery, Inspection, and Agriculture


As drones continue to revolutionize industries such as delivery, inspection, and agriculture, the importance of reliable fastening elements cannot be overstated. The fasteners used in drones play a critical role in ensuring their structural integrity, operational efficiency, and safety. To meet the evolving demands of these high-tech applications, fasteners must exhibit specific characteristics, including high strength tolerance, vibration and corrosion resistance, and innovative yet safe designs.

Essential Fastening Elements for Drone Components

Propellers and Motors

The propellers and motors are critical to the flight performance and stability of drones. The fasteners used in these components must withstand high rotational speeds and significant vibrations. Key fasteners include:

  • Thread Sealing: Ensures secure fastening and prevents loosening due to vibrations.
  • Flange Hex Nut: Provides a larger bearing surface to distribute the load and resist loosening.
  • Anti-Loosening Washer: Reduces the risk of fasteners loosening due to vibration and dynamic loads.
  • Shim Washers: Used for precise spacing and alignment of components.
  • Circlips: Retain components on shafts or in housings.
  • Button Head Cap Screws: Offer a low-profile head for reduced aerodynamic drag.
  • High Precision Machine Parts: Ensure accurate and consistent assembly, crucial for the balance and performance of the drone.

Landing Gear Base

The landing gear of a drone must be robust to absorb impact and provide stability during takeoff and landing. Fasteners in this area include:

  • Shim Washers: For fine adjustments and spacing.
  • Button Head Cap Screws: Provide a secure fastening with a smooth finish.
  • Threaded Inserts: Enhance the strength of fastened joints, especially in composite or plastic materials.
  • Thread Sealing: Prevents loosening and ensures a secure connection.

Drone Body

The body of the drone houses critical systems and must maintain structural integrity under various conditions. Fasteners here include:

  • Multifunctional Screws: Versatile screws used for multiple applications and materials.
  • MM Welding: For permanent joints that require high strength.
  • Stainless Steel Flat Countersunk Head Screws: Offer a flush surface finish and corrosion resistance.
  • Stainless Steel Pozi Pan Head Screws: Provide excellent torque transfer and corrosion resistance.

Battery Pack

The battery pack is the powerhouse of the drone, requiring secure and reliable fasteners to ensure safety and performance. Key fasteners include:

  • Cable Ties: Organize and secure wiring within the battery pack.
  • Cable Mountings/Clamps: Hold cables in place and prevent movement.
  • Clinching Nuts and Studs: Provide strong, permanent threads in thin materials.
  • Stainless Steel Flat Countersunk Head Screws: Secure components with a flush finish.
  • Stainless Steel Pozi Pan Head Screws: Ensure reliable fastening and ease of maintenance.

Electronics Systems (Devices & Components)

The electronics systems of a drone include sensors, cameras, and other critical devices that require secure and precise fastening. Important fasteners include:

  • Cable Ties: For organizing and securing wiring.
  • Cable Mountings/Clamps: Maintain cable positions and prevent interference.
  • Plastic Rivets: Lightweight and non-conductive, ideal for electronic components.
  • DC Fans: Fastened securely to provide necessary cooling.
  • Wire Connectors: Ensure reliable electrical connections between components.

Conclusion

The rapid advancement of drones in industrial inspection, package delivery, agriculture, and beyond is driving the need for specialized fastening solutions. These fasteners must combine high strength, durability, and innovation to meet the rigorous demands of modern drone applications. By ensuring the reliability and safety of drones, these fastening elements play a vital role in the ongoing transformation of these industries. As technology continues to evolve, so too will the fasteners, keeping pace with the ever-growing capabilities of drones.

7 criteria to prevent material fatigue

Image
Material fatigue is defined as an accumulating degradation of material caused by dynamic stress with amplitude below the tensile strength limit. From the practical perspective we can divide the fatigue into two groups:  low-cycle fatigue with number of cycles up to 104 and amplitude of stress above the yield point, where plastic deformation predominates  high-cycle fatigue with number of cycles more than 104 and amplitude of stress, usually way below the yield point, where elastic deformation predominates Low-cycle fatigue is not important for a design of the joint. During the low-cycle fatigue process, stress amplitudes usually exceed the yield point. Fasteners shouldn´t even reach this value of stress. On the other hand, we should be aware of the high-cycle fatigue! Designers of a fastened joint should always consider the influence of high-cycle fatigue when dynamic forces are expected!  On the figure typical example of dynamic loading cycle can be seen. The most important variab
