Smart Coating for In-Situ Monitoring of Engine Components

Depositing a crackwire incipient crack sensor on turbine engine disks and blades for detection based on signals generated from its interaction with microwaves

• Developed a method for nondestructive inspection (NDI) of disks and blades using a deposited crackwire sensor
• Developed a microwave based technique for non-contact sensing of crack initiation and location
• Method tested on sample coupons and a simulated disk

• Received a contract to participate in an FAA-sponsored test on an engine that will be run to destruction. Test results will be evaluated by the Navy and several engine manufacturers for further development and application
• Explore with engine manufacturers potential extension to sense additional engine safety and performance parameters
• Application of this technology will increase the safe operating life of turbine engines, as well as prevent catastrophic uncontained engine failures

• The Navy has stated that in-situ NDI can save $1B on disk servicing over the life of an aircraft. Other fleet owners will also benefit proportionate operational savings
• Engine manufacturers are interested in using the technology for both in-service aircraft and during development
