SHM has the capability to detect small defects in composites with high-resolution accuracy, including incipient damage that is not easily detectable. Additionally, SHM systems spot changes in the material over time, which can be used to monitor airframes for damage incurred during routine operation. This system can be used not only to perform NDE on components, but also to monitor the airframe over its entire life. The knowledge gained from the vehicle health management sensors decreases the down-time of the vehicle while increasing the safety of the crew. According to the project's manager, David Kordonowy, "Interpreting the sensor signal into meaningful information -- where the damage is and how extensive it is -- has been a major challenge to structural health monitoring until now. Our NDE/SHM concept addresses this difficulty by using calibrated sensors with robust algorithms to detect damage that cannot be seen with the naked eye."
The NDE/SHM contract builds on Aurora's work with Sikorsky Aircraft Corporation on the CH-53K Helicopter. Aurora is a Tier I Supplier to Sikorsky on the CH-53K Heavy Lift program, supplying the Main Rotor Pylon (MRP) and No. 1 and 3 Engine Nacelles.
