Aircraft Certification (Static Electricity Dischargers)

Click For Summary
SUMMARY

The discussion centers on the certification requirements for static electricity dischargers, specifically wicks placed at the wingtips of aircraft. Key factors influencing certification include surface area, aircraft speed, and the materials used in construction. While references to CS 23 and CS 25 provide procedural guidelines, they lack specific technical details on calculating the placement of static discharge wicks. The community highlights the need for proprietary methods or academic research to address these gaps.

PREREQUISITES
  • Understanding of aircraft certification standards, specifically CS 23 and CS 25
  • Knowledge of static electricity effects on aircraft performance
  • Familiarity with materials used in aircraft construction
  • Basic principles of aerodynamics and aircraft design
NEXT STEPS
  • Research the specific certification processes outlined in CS 23 and CS 25
  • Explore academic papers on static electricity discharge in aviation, such as SAE paper 520088
  • Investigate proprietary methods used by aerospace companies for static discharge calculations
  • Learn about the impact of static electricity on communication systems in aircraft
USEFUL FOR

Aerospace engineers, aircraft certification specialists, and professionals involved in aircraft design and safety will benefit from this discussion.

The little wicks placed at the wingtips to get rid of static electricity on the wings and body of the aircraft are vital to aircraft.
I am interested in what the certification requirements for placing these ont he wings. I assue the formula of would include things like
1-surface area
2-speed the aircraft can reach
3-material used on the aircraft...

Is there a quick right hand rule for this ( place at-least 3 per wing type of deal) I assume there was a lot of testing done to figure this out, as the static electricity build up on the winds can mean a big degradation for communication with the tower and GPS signals.

Hi,
Sections 23 and 25 are a bit "broad" and doesn't really say specifically anything about calculating the static discharge wicks. It gives a lot of details on procedural items, not technical. Usually companies come up with proprietary ways or some academic papers get released.
I have found these and would like to share with the rest of the community.
