Fatigue-Free Platforms: Vision for Army Future Vertical Lift Aircraft

Speaker: Dy Le
Mechanics Division Chief
Vehicle Technology Directorate
Army Research Laboratory

Abstract:
Army’s goal for aviation platform sustainment is “zero-maintenance.”Scientists and engineers from the U.S. Army are exploring the underpinning science and technology (S&T), which can be used to achieve this goal. The Army Research Laboratory (ARL) and Aviation and Missile Research, Development and Engineering Center (AMRDEC) have recently developed a holistic system approach, “Virtual Risk informed Aviation Maneuver Sustainment” (VRAMS), which integrates a wide range of technologies including the material “genome”, damage precursors, self-healing, real-time risk assessment, autonomous self state awareness and stress reduction methods. The Army S&T efforts aim at (a) developing superior materials, (b) understanding damage precursors and exploring sensing strategies to detect them prior to the onset of microcracks or degradations, (c) advancing intelligent self-repair capabilities at the microscopic level before performance degradation and critical failure, (d) integrating in situ sensing elements and intelligent data collection with minimum hardware and wiring accessories, and (e) developing real time robust risk assessment capability and adaptive maneuvering limitations to ensure acceptable stress levels to sustain “fatigue-free” structural components without maintenance over desirable time intervals.

Bio: Mr. Dy Le joined the Vietnam Air Force in 1972 and became a pilot during the Vietnam War. From 72-74, he was trained at the Air Force Officer Training Center in Vietnam, Lackland Air Force Base in San Antonio, TX and Army Aviation Center at Fort Rucker, AL. In 1974, he was commissioned and received his aviator rotarywing from Fort Rucker, returned to Vietnam and served at Nha Trang Air Force Base. From 1986-1997, Mr. Le lead and managed various propulsion research programs at the Naval Air Propulsion Center. From 1997-2008, he joined the FAA Technical Center in Atlantic City, NJ as a Program Manager focusing on the Rotorcraft Damage Tolerance/Health & Usage Monitoring System research. Currently, Mr. Le is the Mechanics Division Chief at the Vehicle Technology Directorate in the Army Research Laboratory. He is responsible for Platform Mechanics, Reliability, and Diagnostics.
