Plasma Fairings for Quieting Aircraft Landing Gear Noise, Phase II
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.

Ultra-high Energy Particle Astrophysics with ANITA-V - Washington University - Co-I
This is a Co-I proposal that should be cross-referenced to the University of Hawaii proposal titled "Ultra-high Energy Particle Astrophysics with ANITA-V", for which Peter Gorham is the Principal Investigator. We propose to fly a significantly improved version of the Antarctic Impulsive Transient Antenna (ANITA) long-duration balloon payload, with a goal of discovering and characterizing ultra-high energy (UHE) neutrinos and cosmic rays in the EeV (Exa-electron-volt) energy range and above. This will be the fifth flight of ANITA payloads, and should achieve the a milestone of 100 days of integrated livetime on orbit, proposed in the earliest flight as a goal for the application of ANITA's novel methodology. Each payload in the series has yielded improved sensitivity, and unexpected results, both in the form of upper limits that excluded long-held predictions for the isotropic neutrino flux from various models, and in the form of serendiptious detections of UHE cosmic rays via radio pulses that were not well understood when ANITA first flew. Moreover, ANITA's ability to perform precision measurements of the pulse shape and polarization properties of the UHE cosmic ray events led to the discovery of candidates for tau-lepton-generated air showers, one in the ANITA-I flight, and most recently, a second candidate in the ANITA-III flight. These events signal the possible appearance of a flux of UHE tau neutrinos, appearing with unexpected properties, in tension with other measurements. ANITA-V will provide an opportunity to elucidate these new potential signals in a compelling way with far-reaching implications for fundamental physics.

Ultra-high Energy Particle Astrophysics with ANITA-V
This is the lead proposal on a multi-institutional proposal. We propose to fly a significantly improved version of the Antarctic Impulsive Transient Antenna (ANITA) long-duration balloon payload, with a goal of discovering and characterizing ultra-high energy (UHE) neutrinos and cosmic rays in the EeV (Exa-electron-volt) energy range and above.

These events signal the possible appearance of a flux of UHE tau neutrinos, appearing with unexpected properties, in tension with other measurements. In addition to these unexpected anomalous cosmic-ray like events, ANITA-III analysis has yielded one potentially interesting neutrino candidate from a possible in-ice shower, a total of two possible candidates from the 2014-2015 flight of ANITA-III. ANITA-IV analysis is well underway, with about 3 times the expected sensitivity of ANITA-III, but could not be completed prior to this proposal. Depending on ANITA-IV results, ANITA-V will provide an opportunity to elucidate these new potential signals in a compelling way with far-reaching implications for fundamental physics, or to bring to fruition the strongest world limits on cosmogenic neutrino fluxes from the combination of all of the flights, with over 100 days of expected exposure.
