Eagle's Background and Experience - The Eagle staff has extensive capabilities and experience in the management of NASA programs and understanding of NASA administrative requirements. We have technical experience in the fields of structures and materials; aircraft noise and sonic boom; aerodynamics and computational fluid dynamics; and flight controls.

Past activities include studies on a wide range of aerospace vehicles such as rotorcraft, general aviation, subsonic, supersonic and hypersonic configurations, and spacecraft. Studies were also done on airport community noise, passenger cabin and crew noise, launch pad noise, and acoustic fatigue of the vehicle structure. Eagle staff has experience in design, ground and flight testing of engine noise suppressors. We also have extensive experience in the design and implementation of ground measurements of sonic booms from aircraft in the NASA Dryden area.

Eagle has broad software capabilities, especially in the areas of aerodynamics and computational fluid dynamics. Eagle staff uses advanced analysis codes and has developed optimization routines utilizing unique parallelization techniques to speed up analysis routines.

Eagle has completed pioneering work in the application of advanced CFD codes to improve subsonic and supersonic airfoils. Eagle holds a patent for modifying the wings of a postproduction civil transport to improve performance. Eagle has also developed a complete modular propeller design code including a GUI (Graphic User Interface) for each module.

Eagle has experience in the use of computer codes including PAB3D, CFL3D, CFL3D with optimizer, FlowMG, COSMOS/M and advanced structural and acoustic codes.

In the area of data archival, Eagle designed and published for NASA a CD-ROM, which included past wind tunnel and analytical studies of a SST configuration. The original NASA investigator, an Eagle staff member, added an assessment of the potential of contemporary CFD tools for analyzing the data.

Eagle Facilities - Eagle uses PC, Sun, and Macintosh work stations for administrative and financial reporting and analysis. Report preparation software programs include Microsoft Office 97 for the PC, Microsoft Office 98 for the Macintosh, and Framemaker 5.5 for the Sun and Macintosh. Adobe Acrobat 4.0 is used on the Macintosh to convert documents to PDF. Photoshop 5.02 is used for image preparation and processing. An Epson 1200 scanner is available for image and document scanning. Omnipage Professional software is used to convert scanned documents to word processor formats.

Eagle has developed a technical computer capability that features Cray level workstations and the latest computer codes to develop innovative engineering designs for the future. Our basic compute server is a Sun 670 MP with 384 MB RAM and 4 125-Mhz Ross processors. We use 2 Silicon Graphics workstations for grid generation work, and a SPARC 5 workstation as our web server. We also have 2 SPARC workstations for basic report preparation.

Eagle staff uses their Cray level workstations and advanced computer codes to support their analysis and concept studies. The base system incorporates the latest in Sun work stations, and is supported by SGI workstations. Eagle has experience in the use of computer codes including PAB3D, CFL3D, and CFL3D with optimizer, FlowMG, COSMOS/M and advanced structural and acoustic codes. We have frequently used government mainframe computers where allowed or specified, most recently in our HSR complete-configuration analyses for Douglas/Boeing.
