AUSTIN, Texas, 13 Feb. 2007. TRI/Austin's diagnostic/prognostic system that is able to monitor aircraft and rotorcraft structural components in flight has just flown aboard the F-15. In 2003, the U.S. Army awarded a $729,888 SBIR Phase II contract to the company to develop the solution.
Phase II focused on ruggedizing the system, optimizing performance, reducing power draw, refining the prognostic/diagnostic algorithms, and building a system for test. The effort culminated in a successful flight test of the LAHMP system aboard the F-15.
"We couldn't have done it without Boeing, our teaming partner, who guided us through the process of getting on a flight test," notes Russell Austin, the principal scientist on the project. "Safety is critical and we had to prove that our system was safe enough to fly on board a plane. We successfully conducted third-party independent testing prior to placing the system on the aircraft and then a ground test on the plane before take-off."
Third-party verification included acceleration testing of up to 6G on 6 axes, as well as RFI/EMI testing. In-house thermal testing showed the system to be operational in the specified range of -40 to 85 degrees Celsius, including thermal shock.
"We developed patented algorithms to determine structural health from on board sensor readings," David Forsyth, the NDE/SHM division manager, remarks. "In addition, we designed the health management platform to be fully customizable for a wide variety of aircraft."
Potential applications include fighter aircraft, such as the Joint Strike Fighter and the F/A-18, military transports, helicopters, commercial aircraft, and rockets.
