ITAC and its partners propose to develop and demonstrate a computational technology and methodology tool for the concurrent automated shaping of aft airframe and nozzle geometries to reduce tactical aircraft jet noise without any performance penalties. The proposed technologies will lead to an integrated tool which inherently maintains critical aerodynamic performance while reducing the noise generated through the process. The ability of the proposed technology to simultaneously address the entire empennage and nozzle geometry represents a quantum leap over existing design tools.

This Phase II SBIR project deals with the design, development, and testing of a "Plasma Fairing" to reduce noise on the Gulfstream G550 landing gear. The plasma fairing will use single dielectric barrier discharge (SDBD) plasma actuators to reduce flow- separations and impingement around the landing gear, which are the dominant sources of landing gear noise. The Phase I project successfully demonstrated the feasibility of the plasma fairing concept on a generalized tandem cylinder configuration that shared important features of key sections of the G550 landing gear, specifically the relationship between the strut and the torque arm. The Phase II extends the concept to a more complex geometry: G550 landing gear. We will develop aeroacoustic simulations using University of Notre Dame's state-of-the-art plasma actuator model and Exa Corporation's flow solver PowerFLOW, coupled with experiments in an anechoic wind tunnel with both aerodynamic and acoustic measurements on a scaled G550 nose gear model to design and optimize a Plasma Fairing configuration that provides significant noise reduction on the G550 landing gear. We anticipate a technology readiness level (TRL) of 5 at the end of the Phase II project.

This Phase II SBIR project deals with advancing the design, development, and testing of an innovative drag reduction concept named ?Smart Longitudinal Instability Prevention via Plasma Surface? using a new revolutionary plasma actuator technology developed at the University of Notre Dame (UND). During Phase I, Innovative Technology Applications Company (ITAC), LLC and researchers from UND developed and demonstrated drag reduction of more than 65% in turbulent boundary layers using the SLIPPS approach. This approach intervenes in the Streak Transient Growth Instability mechanism which is a dominant mechanism in the production of drag in turbulent boundary layer flows. In Phase II, we will investigate and test the use of SLIPPS concept at both higher Mach number and Reynolds number flows, as well as build an improved understanding of the physics in order to make even further efficiency gains possible. Phase III will advance the TRL to a level suitable for flight tests and integration into production systems.

Use of an airborne platform for a directed energy system is currently severely limited by aero-optic aberrations arising from density variations in air flowing over the aircraft; the primary limitation is for aft pointing applications. Innovative Technology Applications Company (ITAC), in collaboration with the University of Toledo (UT), is working to develop techniques of integrating flow control with a turret/adaptive fairing design that provides a large field of regard for propagation of a lethal beam from an airborne platform at subsonic, transonic and supersonic speeds. BENEFIT: The technology developed in the proposed work to improve field of regard for aircraft-mounted turrets will make these systems significantly more capable, both for the anti-missile and communications role. There are potential commercial applications for optical communications for transonic aircraft. Related applications may benefit other optical systems, such as vehicle-mounted cameras and telescopes.

ABSTRACT: Flight tests of hypersonic maneuvering vehicles are a challenging but necessary endeavor. While ground tests and numerical simulations can provide important guidance regarding vehicle performance, they are both limited in their reach. Likewise surface-based measurements during flight tests provide valuable information, but do not provide sufficient insight into the complex flowfield to allow unambiguous conclusions to be drawn from the flight data. To address the need for off-body measurements in flight experiments, the University of Notre Dame and ITAC, LLC are partnering to investigate the possibility of using laser-based aero-optic techniques. The proposed Phase I STTR will demonstrate the essential components of the approach in a supersonic ground test facility. The technology developed in this project offers the possibility of in-flight off-body flowfield measurements for a variety of purposes, including hypersonic weapon system flight tests and, potentially, as part of a high speed store separation control system. BENEFIT: By providing a clearer picture of the flowfield around a flight test vehicle, the proposed technology will allow deeper insight into the phenomena experienced by the vehicle. In this manner, many issues which must remain ambiguous when testing with current technology could be definitely determined. This will allow the development of safer and more reliable systems, which will consistently perform in a predictable manner because the flight envelope will be better understood.
