E-MAIL: Steve Craig, steve.craig@grc.nasa.gov. NASA/GRC is hereby soliciting information for potential sources for the 2DB Inlet Flight Test. Impact: Capitalizing on the accomplishments made as part of the Critical Propulsion Components element of the High Speed Research (HSR) technology development program, the 2DB inlet flight test would accelerate progress toward meeting the Three Pillars Revolutionary Technology Leaps objective. In doing so, the proposed demonstration would positively impact the High Speed Travel and other roadmaps. Addressing the High Speed Travel roadmap directly, the proposed flight test would demonstrate an economically viable, critical component and its system level technologies while providing the design space for the acoustic treatment that studies have shown is needed to comply with noise standards. The robust design approach to the multivariable integrated control goals of the test would provide lower weight, higher maturity, lower cost, integrated technologies for the inlet and its subsystems. Purpose: The purpose of the tests would be to demonstrate the first ever, viable, mixed-compression supersonic inlet for application to a Supersonic Transport (SST) and technologies for enabling supersonic flight over land. A critical element of this effort is the demonstration of the 2DB's throat stability bleed system, obviating many years of controls development while improving performance. The combined ability of LIDAR and robust, integrated controls for improving the 2DB's operational performance and dynamic response while reducing aircraft weight would also be proved. Schemes for sonic boom reduction and nacelle-wing PAI would also be evaluated. Description: A supersonic inlet/engine pod and a Light Detection and Ranging (LIDAR) atmospheric disturbance sensor carried by an SR-71 are proposed to demonstrate the 2DB inlet's performance and operability with enhanced unstart tolerance. The benefits of applying multivariable integrated inlet/engine controls to these systems as well as novel sonic boom reduction and propulsion airframe integration (PAI) concepts would also be assessed. Description of Services: 1.) Research Engineering (aerodynamic design and analysis) support of the propulsion system outer mold line/boundary layer diverter/wing simulator section. 2.) Mechanical design of the wing simulator in coordination with inlet bleed system design and inlet modifications 3.) Fabrication and instrumentation of the wing simulator section and boundary layer diverter hardware. 4.) Engineering support for the sonic boom reduction elements of the 10x10 SWT and SR-71 tests as well as data reduction and reporting.
