NASA "Hershey Bar" Test for Aerodynamically Strong Wings

Engineers at NASA's Armstrong Flight Research Center tested a composite structure, known as the 'Hershey Bar' test article, by exposing it to increasing weight loads. The purpose of the structure is to test and validate ways of developing flexible wings that are structurally and aerodynamically strong. This testing will help engineers prepare for testing of the larger, passing aeroelastic tailored wing, which is scheduled for 2017.
