Reduced-Order Model for the Prediction of Supersonic Aircraft Jet Noise

Phase 1 SBIR

Agency: Air Force
Topic: AF151-065
Budget: 01/01/15 - 12/31/15
PI: Praveen Panickar

ABSTRACT:The increased sound produced by tactical aircraft has become more problematic with the enhanced performance requirements that are being set forth for the next generation war fighter. ?Given the complexity of the engine and the flow that it produces, accurate predictions of the full-scale exhaust stream and far-field acoustics are still ...

Phase Transitions, Nucleation and Mixing Modeling through Trans-Critical Conditions

Phase 1 STTR

Institution: Rutgers University

Agency: Air Force
Topic: AF14-AT23
Budget: 12/19/14 - 09/19/15
PI: Dr. Ashvin Hosangadi

ABSTRACT: The goal of the Phase I effort is to develop a detailed and comprehensive plan that identifies specific, tangible improvements to improve the fidelity of modeling trans-critical combustors. Both hydrogen/oxygen as well as hydrocarbon (RP-1, RP-2) / oxygen systems will be considered. The focus will be on developing improved modules fo...

Techniques to Suppress Cavitation in Liquid Rocket Engines

Phase 2 SBIR

Agency: Air Force
Topic: AF121-188
Budget: 09/24/14 - 12/20/16
PI: Dr. Ashvin Hosangadi

ABSTRACT: Next generation liquid rocket systems, envision novel designs for cryogenic turbopumps that exhibit high suction performance with low inlet pressures, operate at high tip speeds to reduce size and weight, and can be throttled over a wide range of low, off-design flow conditions where the inlet flow quality is poor with large backflow. ...

Design Optimization and Analysis of Advanced Exhaust Systems

Phase 1 STTR

Institution: Pennsylvania State University

Agency: Navy
Topic: N14A-T005
Budget: 09/09/14 - 04/09/15
PI: Mr. Neeraj Sinha

Historically, aircraft engines have featured relatively simple axisymmetric exhaust shapes with several moving parts; however, future engine exhaust systems are expected feature compact, sinuous ducts with complex non-axisymmetric shapes, fixed exit areas, thrust vectoring etc., constructed with a minimum number of moving parts. Their exhaust pl...

Aerodynamic Analysis of Deployed Bay Doors on Modern High-Speed Aircraft

Phase 2 SBIR

Agency: Air Force
Topic: AF131-004
Budget: 07/23/14 - 10/25/16
PI: Mr. Neeraj Sinha

ABSTRACT: The need for evaluation of aerodynamic loads on internal weapons bay doors comes from the US Air Force's requirement to open doors on many of its aircraft during flight. This ranges from an aircraft's low-speed opening of landing gear doors and speed brakes to opening weapons bay doors in supersonic flight. This sets up a situation for...
