Remote Access and Analysis of Aeronautics Data

摘要

The DARWIN system has been developed in conjunction with new computational and experimental test technologies to provide remote access to the integrated knowledge generated from these independent systems. Version 2.5 of the DARWIN system for remote access to and analysis of aeronautics data was completed and deployed at the Ames wind tunnels in December 1999. The new and improved version was used by the Wind Tunnel Operations Division to support one of the first tests in the newly modernized 11-by-11 Foot Transonic Wind Tunnel in early January 2000. The deployment of DARWIN version 2.5 at the Ames wind tunnels concluded a year of work by the DARWIN development team on implementing enhancements to the DARWIN system. The major new feature of this release is a completely redesigned database schema. Building on 3 years of experience with the original database and on feedback from collaborators at NASA Langley, Eglin Air Force Base, and Arnold Engineering Development Center, the team developed a schema that can store values for a wide range of variables and thus flexibly capture information from disparate wind-tunnel test entries. All components of the DARWIN system, including the client, administrator, and database loader, were completely reworked to take advantage of the new database schema.
