TSi wins Army BAA award for non-destructive helicopter evaluation to enable Condition Based Maintenance TSI, as part of a multi-disciplinary team of industry, small business, and academia led by prime contractor Bell Helicopter, Textron, was awarded a three-year Army Broad Agency Announcement (BAA) contract by the Aviation Applied Technology Directorate of Ft. Eustis, VA. Top-level goals of this program are to significantly reduce operational costs incurred by the Army on helicopters, which are complex and require three hours of maintenance for every hour of flight time. More specifically, the BAA project seeks to enable Condition Based Maintenance (CBM) practices. Under a $1.2M subcontract, TSI will support Bell to develop systems that will provide expert guidance to decide when to replace flight critical components based on accumulated damage. It is envisioned that condition-based replacement will lead to more reliable aircraft and also reduce preventive maintenance costs that traditionally replaces components regardless of remaining useful life. TSI and the University of Maryland (UMD), led by Dr. Darryll Pines, will develop an integrated hardware/software system for structural damage detection and diagnostic approaches based on the Acousto-Ultrasonic method for non-destructive evaluation. High frequency structural waves are used to interrogate the structure for changes due to damage. This technology will be used by Bell and the US Army to monitor crack growth and ballistic damage. Sensors and actuators based on piezoelectric materials will provide in-situ transduction to allow for constant monitoring of the component. TSI will demonstrate the technology on Bell full-scale helicopter vehicle components and integrate with Bell Helicopter's Health and Usage flight Monitoring Systems (HUMS). |
