My plane’s stabilizer is slightly wider than the average Airstream trailer, so it's designed to be removable. That way I don’t have to worry about it when I’m driving.

This part of the aircraft was the most persistently frustrating to design. It’s because there are so many control components and load-bearing components close to each other. I didn’t see any existing on the search, except BoKu explaining about the Libelle. Here is my (WIP, work in progress) design and a few sketches. Critique it, or not.

Goals:
  • Twice the number of individual components, or fewer, as compared to a fixed installation.
  • After installation, the stabilizer must align within 0.3 degrees without using a measuring tool.
  • Strength requirements --
  • Theoretical ultimate load, 4470 lbs
  • Static loading approximation, linear deflection: up to 1500 lbs
  • Weight approximation, for the elevator and h. stabilizer: 25 lbs
Principles:
  • Reduce complexity.
  • Minimize failure points.
  • Make the structure easier to analyze.
  • Respect the limitations and best practices of composite materials.
