ARPPAS (Automatic Repair Planning and Part Archival System) Rapid Repair Analysis Tool Navy SBIR FY2006.1 Sol No.: Navy SBIR FY2006.1 Topic No.: N06-005 Topic Title: ARPPAS (Automatic Repair Planning and Part Archival System) Rapid Repair Analysis Tool Proposal No.: N061-005-0548 Firm: Federal Engineering Associates 6679 McLean Dr. McLean, Virginia 22101-4002 Contact: Fred Perkins Phone: (703) 506-9212 Web Site: www.fea-llc.com Abstract: Federal Engineering Associates LLC (FEA-LLC), working with its partners Composite Engineering Inc., AGFM, and MSC Software (the manufacturer of the finite element analysis software used in designing the F-35), proposes development of ARPPAS (Automatic Repair Planning and Part Archival System) a computational system for automatically modeling, designing, and validating structural repairs for the F-35. The SBIR project will provide a web-based tool used to automatically model, define, and validate structural repairs for advanced composite aircraft components, configured to provide support to repair depots, ships at sea, and forward-based maintenance centers. Phase I of this SBIR will demonstrate capabilities, operating shell, and user interface for non-expert users on a a solid laminate skin bay repair Benefits: The anticipated benefits of ARPPAS include enabling line repair technicians to input only essential data to define a composite F-35 aircraft part repair using a web-based user interface, and receive in return an automatic finite element-based repair definition and analysis. The automatic analysis will validate the repair sufficiency, its compliance with design standards, and its safety using reference geometric models and data stored in databases as modified by the user. Non-expert users of ARPPAS will benefit from the automatic, comprehensive structural analysis of the proposed repair and automated expert definition of acceptable repair procedures. ARPPAS has widespread potential use for reducing cost and increasing quality of composite aircraft part repairs in government and civilian aircraft repair facilities. Expert users will benefit from the ability to track, monitor, and control the repair definition process. ARPPAS also enables expert maintenance support for warfighters in remote locations, providing a means for validating airworthiness of emergency repairs via low-bandwidth web-based applications that run on ordinary computers and laptops. ARPPAS will provide similar benefits and substantial cost savings to commercial aircraft repair facilities, and by extension, to facilities repairing other critical equipment with similar structures and demanding performance requirments.
