Challenges towards Successful Integration and Test of SMA Aerospace Applications

Boeing’s successful flight tests in 2005 of Variable Geometry Chevrons (VGC) on a 777 and the 2012 Adaptive Trailing Edge (ATE) on a 737 clearly demonstrated a high technology readiness level (TRL) for SMA actuator systems. These tests confirmed that the unique capabilities of SMA technology can enable solutions for demanding aerospace requirements including reduced noise, reduced emissions, and improved efficiency.

Each flight test presented distinct challenges for the SMA actuator system to meet flight test objectives, be considered safe, and be approved for flight. In this presentation Mr. Mabe will discuss engineering, integration, and program challenges encountered during the flight test programs that are unique to SMA actuation. He will describe how the flight test team overcame each challenge, lessons learned, and suggestions for how those experiences can help accelerate the introduction of SMA actuation into aerospace applications.
