New On-Board Aircraft Health Monitoring System Takes Flight on F-15.

TRI/Austin, Inc. is Developing a New System That Can Monitor Aircraft Health During Flight

The LAHMP[TM] Health Monitoring System Recently Passed a Flight Test Aboard an F-15

AUSTIN, Texas -- In 2003, the Army awarded an SBIR Phase II contract for $729,888 to TRI/Austin to develop a diagnostic/prognostic system that could monitor aircraft and rotorcraft structural components in flight. 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," noted 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 85C, including thermal shock.

"In order for the LAHMP system to pass the flight test, the system could not adversely affect the plane, the plane could not adversely affect it and it had to be operational during the flight." During the flight test the LAHMP system took data from three areas on the F-15.

David Forsyth, the NDE/SHM Division Manager, sees a lot of potential for the LAHMP system. "We developed patented algorithms to determine structural health from on board sensor readings. 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.
