US Army TACOM

A field expedient method for detecting cracks in wheel spindles was developed to support 13 variants of the US Army Stryker tactical ground vehicle. Twenty-two inspection kits were designed and deployed. A Technical Medal of Achievement was presented to Purdue by Col. Fuller US Army/Stryker PMO for delivering this system. The kit is being expanded for inspection of newly designed wheel assemblies.

US Army Redstone Arsenal

A health monitoring system for locating and quantifying shock loadsto composite filament wound missile casings was developed for US Army AMRDEC at Redstone Arsenal. The system uses a single light weight triaxial sensor to measure the response of the missile and mathematical model to identify impact loads and damage caused by severe loads. Residual burst pressure in damaged missiles has also been accurately predicted using this technology. Software and hardware have been demonstrated and AMRDEC is evaluating this system for use in future hellfire missiles to ensure readiness.

US Army Research Laboratory

A method for sensing ballistic impacts and damage in ceramic body armor has been demonstrated for the US Army Research Laboratory. The method uses a single sensor to identify the location and magnitude of ballistic impacts and identify cracking. ARL is considering the method for technology transition to personnel armor and other protective equipment (helmets). The ultimate objective is to develop “smart” armor that provides military personnel with information pertaining to the integrity of the armor as well as data for use in the treatment of impact trauma and other injuries.

US Marine Corps 53K Program

A non-contact method for identifying weak spots in aircraft structural materials and components (fuselage, blade, etc.) has been developed for the USMC PMA-261. The method utilizes a long-range scanning laser vibrometer to quickly identify material that is damaged beneath the surface. The method is being matured for transition to the CH-53E/K fleets to support condition-based maintenance.

US Air Force

Micro-radio-telemetry sensors and display units have been deliveredto monitor bearing cages in gas turbine engines and other driveline components for Kirtland US Air Force Base. Micro-strain sensors withwireless telemetry have also been developed and implemented. These technologies are also being developed for Caterpillar and the USAF foruse in monitoring a wide range of equipment.

DoD Industry

Health monitoring software and hardware has been delivered to DoD industry for use in monitoring a wide range of machinery (engines, drivelines, wheels, wire harnesses, etc.). These systems use physical models in conjunction with multi-variable signal processing techniques to detect faults in the early stages. The objective of these systems is to reduce operation & support costs and ensure readiness.
