Project Description

Hide

This CIF project allowed for the exploration of the FMC material for wing design applications. Researchers gained experience working with viscoelastic materials and determined that, while not currently appropriate for wing designs, FMC material may still provide value in other aerospace applications where temperature variation and stiffness losses are better tolerated. Collaboration with research partners formed a basis for future mutually beneficial research efforts.

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. More »

Anticipated Benefits

Show

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 More »
