  1. Efficient Radiation Simulation in Complex Geometries with Applications to Planetary Entry

    SBC: Jabiru Software and Services            Topic: A206

    NASA aerocapture missions require an accurate evaluation of radiative thermal transport in order to simulate the aerothermal environment around space vehicles. However, present day computation of radiative transport in this complex multi-dimensional environment is frequently done using simple one-dimensional tangent-slab approximations or optically-thick approximations which compromise the accura ...

  2. New Class of Multi-Channel Spectrometers Based on Diffraction Grating Array

    SBC: LightSmyth Technologies            Topic: S108

    Remote chemical analysis via spectroscopy is an important tool in the arsenal or Earth and Planetary Science. Grating technology, which is the centerpiece of most modern spectroscopy systems, has not change significantly in the last 60 years since introduction of holographic gratings. Recently LightSmyth introduced new technology for design and fabrication of diffraction grating elements based on ...

  3. Variable Speed Rotor System

    SBC: Peregrine Power LLC            Topic: A210

    Variable speed rotors will give helicopters several advantages: higher top speed, greater fuel efficiency, momentary emergency over-power, resonance detuning capability and a reduction in noise. The applicant proposes to develop such a system using a doubly-fed planetary gear box with advanced SiC-based power electronics and motors. The new components enabling variable speed will be rated at a f ...

  4. Airspace Analyzer for Assessing Airspace Directional Permeability

    SBC: Innovation Laboratory, Inc., The            Topic: A301

    We build a software tool which enables the user (airline or Air Traffic Service Provider (ATSP)) the ability to analyze the flight-level-by-flight-level permeability of airspaces constrained by weather-hazards (turbulence, icing, and convection). The Airspace Analyzer automatically determines the space-time boundaries where weather hazards constrain capacity. The solution approach is based on an ...

  5. Nonhazardous Urine Pretreatment Method for Future Exploration Systems

    SBC: UMPQUA RESEARCH COMPANY            Topic: X302

    A novel urine pretreatment that will prevent biological growth or chemical instabilities in urine without using hazardous chemicals is proposed. Untreated urine fosters biological growth, ammonia generation, creation of bio-solids, and inorganic precipitates, which foul water and air reclamation hardware. The current Russian system employs hexavalent chromium, a strong oxidant and carcinogen, an ...

  6. Single Photon Sensitive HgCdTe Avalanche Photodiode Detector (APD)

    SBC: VOXTEL, INC.            Topic: S602

    Leveraging Phase I SBIR successes, in Phase II, a single photon sensitive LIDAR receiver will be fabricated and delivered to NASA. In Phase I, high-gain, electron-initiated avalanche photodiodes (e-APDS) were designed, manufactured, and characterized over a range of temperatures. The e-APDs, sensitive from 1064 nm to 4300 nm, were fabricated in single-layer p-type HgCdTe films grown using liquid p ...

  7. Efficient Low-Dark-Count Detector for Photon Counting

    SBC: VOXTEL, INC.            Topic: N/A

    Voxtel proposes to develop fiber-coupled near-infrared avalanche photodiode (APD) receivers with photon detection efficiency (PDE) and dark count rate (DCR) with more than two orders of magnitude faster maximum count rate (MCR) than Geiger-mode APDs, which are constrained by a fundamental tradeoff between DCR and MCR: if the APD is cooled to reduce DCR, then its dead time must increase to avoid af ...
