Digital Aircraft Data Storage System

ABSTRACT: To address the Air Forces need for an open-system-architecture data transfer device (DTD), Physical Optics Corporation (POC) proposes an innovative approach that maintains compatibility with existing mission planning equipment (MPE) and aircraft data recording sources. This approach addresses MPE media obsolescence, while providing a solution compatible with legacy aircraft and lays the foundation for an option to execute a longer-term strategy that completes the avionics modernization of digital media and data recording systems throughout the USAF. In Phase I, POC investigated aircraft platforms identified by the USAF and analyzed each selected platform with its currently deployed Data Transfer Unit (DTU) and Data Transfer Device (DTD), focusing on the interfaces between the DTD media and the DTU. POC then proposed a form, fit, and function replacement for legacy DTUs. This novel technical approach for digital storage media, called Digital Aircraft Data Storage (DADS), requires no aircraft harness rewiring or Operational Flight Program modifications. In Phase II, POC developed a preliminary ruggedized design for DADS using a Government-provided data storage cartridge and targeted the F-15C/E aircraft for first implementation. In Phase II(e), POC will develop a detailed design of DADS and build three prototype units for evaluation testing. BENEFIT: DADS immediately addresses the Air Forces near-term critical obsolescence issues with current aircraft data transfer devices that are based on obsolete/aging technologies, such as PCMCIA and magnetic disks, by providing a digital media storage solution that is compatible with existing equipment and uses open-system standards. This approach gives the Air Force a low-risk strategy to mitigate immediate obsolescence issues and supports an optional path for longer-term growth to a fully modern digital storage solution.
