Landing Gear Structural Health Prognostic/Diagnostic System Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-043 Topic Title: Landing Gear Structural Health Prognostic/Diagnostic System Proposal No.: N121-043-0598 Firm: Progeny Systems Corporation 9500 Innovation Drive Manassas, Virginia 20110 Contact: Edwin Michna Phone: (401) 846-0111 Web Site: www.progeny.net Abstract: For this SBIR, Progeny Systems is proposing a network/node-based, flexible and scalable landing gear structural health prognostic/diagnostic system that employs RF wireless technology to minimize aircraft wire routing. The proposed design includes a secure wireless network of Landing Gear Structural Health Monitor (LG-SHM) modules, one installed within each landing gear compartment. Each LG-SHM module operates independently, recording data from local strain gauges and performing fatigue damage processing. Via a wired or secure wireless communication link with the master LG-SHM module, the user can access prognostic/diagnostic information for all landing gear, and can also access aircraft weight and CG calculations. The master LG-SHM wirelessly and securely communicates with the other LG-SHM modules, requesting and merging fatigue assessments and direct load data upon user request. The master LG-SHM is also linked via a wired connection to the aircraft data bus network, thus allowing for future access from cockpit computer systems. For the proposed system, the Progeny team intends to leverage its expertise in RF wireless technology and experience in developing low-cost, network/node-based, compact, and ruggedized data acquisition systems. Benefits: Military: - System can be mounted to a host of transport based platforms where a wirelessly interfaced device for stress and strain measurement would be desirable - Adaptable to field based systems for forecasting preventative maintenance of fielded equipment based on recorded usage data - Adaptable for special environments or harsh conditions i.e. Sea Based Platforms, Space or Limited Atmosphere, Missile Ordinance Launch Events Commercial: - Multiple direct applications for stress or fatigue measurements with Commercial Airlines, Trucking, Trains and other transportation related functions - Adaptable to many situations where measurement of fatigue or loading during specific events or over time duration is desired - Utilize / Integrate Transportation GPS tracking data for repair of roads or track a need for repair in a targeted area by attachment to in service fleet vehicle Return
