Flexible Matrix Composites for Passive Flutter Suppression
Completed
TRL 2 (started at 2, targeting 2)
Description
Fabricate & test a small baseline non-tuned flutter model carried on F-15. Fabricate & test a small FMC tuned flutter model carried on F-15. ATW 1 and 2 were previously flown on the F-15. Demonstrate that tuned article flutter airspeed is 15% higher than non tuned.
Benefits
Future aircraft require both light weight and high aerodynamic efficiency. High aspect ratio and/or thin wings. Inherently flexible configurations. Flexible matrix composites (FMC) could provide sufficient suppression of flutter modes passively to enable these future aircraft FMC could alleviate need for active control of flutter modes while maintaining weight budgets

How to get involved
This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
