Description

FAA predicts that air traffic will double or even triple by 2025 and unless solutions that enable improvements in the use of airspace can be developed and implemented, significant airspace congestion will occur. Advancements in aircraft capabilities via new technologies can enable aircraft to operate more efficiently in the NAS and to operate safely in areas previously restricted. AeroTech proposes to enhance ATM simulations and the assessment of Performance Based Operations (PBO) by developing an Autonomous Aircraft Decision Making Model for Weather Hazard Avoidance based on the aircraft's weather hazard detection capabilities, ATC constraints, FAA regulations, and operator policies. The model will provide autonomous guidance for aircraft in ATM simulations such as FACET and ACES. PBO and traffic flow schemes can be assessed for any scenario by varying the detection capabilities of simulation aircraft, regulations, and/or policies, and examining deviation decisions, flight paths, safety impacts, and NAS throughput. Phase I will develop and test the Model's methodology and algorithms, and perform a proof of concept study. By the end of Phase II, the Model will have been implemented and tested in ATM simulations, and will enable researchers to improve NAS operations through new traffic flow techniques based on PBO.

Description

Large aperture antennas are of interest to NASA for applications in establishing high-speed communication relays for interplanetary missions. Design goals include 20 meter apertures. In order to minimize mission costs at these large diameters, weight must be severely restricted. Adherent Technologies, Inc. (ATI) has developed two technologies for ultra-light space structures and antennas, the Rigidization on Command<SUP>TM</SUP> (ROC) concept, uses UV-curing resins to stabilize inflated structures and a self-deploying foam antenna concept at small aperture. These technologies were combined in the Phase I program to produce a foam stabilized antenna with a ROC reflector surface. The areal density of the 0.6 m devise was 2.2 kg/m3. In the Phase II program, ATI will team with ILC Dover and Allied EM to develop the needed materials, design, manufacture, deploy, and test a 3 m Ka band antenna based on the foam stabilized inflatable technology. ATI will lead the materials development effort, optimizing the foam formulations and injection methods, as well as create a custom ROC resin for antenna applications. ILC Dover will manufacture the necessary inflatable mold, and Allied EM will be responsible for the RF design and testing.

Description

The objective of the Phase I is to develop, demonstrate and test a novel instrument based on laser absorption diagnostics for fast, in situ measurements of important parameters (static gas temperature, bulk gas velocity, and gas concentration) in the high speed flows typical in NASA propulsion test facilities. In addition, the instrument will be easy to move (translate) during operation and thus allow measurements at different locations during a test run.

Description

The multi-cell thermal battery (MCTB) is a device that can recover a large fraction of the thermal energy from heated regolith and subsequently apply this energy to heat up cool regolith. The individual cells of the MCTB contain a thermal storage media that is specifically designed for optimal performance at a given temperature range. Each of these cells is charged with thermal energy from hot regolith that has been used in a lunar ISRU application. Once the MCTB is charged, the heat is transferred from the battery to newly harvested regolith. In this manner over 85% of the heat can be transferred from the expended to the new regolith. This is a large improvement especially considering that this reduces the heating requirement to produce 1000 kg of O2 from lunar regolith from an average of 1 kW to only 0.15 kW (assuming 3% O2 recovery by weight). The other irreducible power consumption of lunar ISRU O2 production is electrolysis which consumes at least 0.3 kW. Hence, using the MCTB decreases the irreducible power consumption of lunar ISRU by 65 %.

Description

Satellite observations of the Earth often contain excessive noise and extensive data voids. Aerosol measurements, for instance, are obscured and contaminated by clouds, possible only on the sunlit side of the globe, and difficult over bright land areas. We propose to explore new filtering and data assimilation techniques for satellite derived aerosol optical depth based on the directional spherical wavelet transform. Initially we will focus specifically on aerosol measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments flying on the Terra and Aqua satellites. In Phase I we will prototype a spherical wavelet filter and assess its ability to smooth aerosol fields and interpolate into data voids. The smoothed fields will be tested against surface network observations of aerosol optical depth. Further, we will build an interface to the Data Assimilation Research Testbed (DART) coupled to the Community Atmosphere Model (CAM) 4. Phase II will employ the wavelet filter and assimilation system to produce aerosol datasets for application in Earth radiation budget observations and atmospheric correction methods.

Description

Aging and durability of aircraft in both the military and civilian sectors are becoming major issues as the existing fleet continues to age. Additionally, the increased use of composite structures in the civilian fleet, such as in the Boeing 787 Dreamliner and the Airbus A380, make the understanding and/or improvement of composite durability, particularly durability of repairs, even more critical. Several areas have been identified as targets for improvement in composite aircraft repair. These include the development of rapid, low temperature repair methods and associated materials as well as development of the quality of repairs when they are made. Adhesion of bonded repairs is one area that needs to be addressed. In the Phase I program Adherent Technologies, Inc. demonstrated a novel moisture-resistant primer system for use in repairs of standard carbon/epoxy composites used in many subsonic aircraft. Our proprietary chemistry comprised of a reactive coupling agent and a carrier resin compatible with standard aerospace epoxy resins bonds directly to the prepared aircraft composite surface while retaining residual functionality that can be cured directly into the matrix of the repair leading to a covalently bound repair, thereby strengthening the repair interface. An increase in bond strength for primed samples relative to unprimed control specimens was noted; the improvement in the fracture toughness of the bonds was particularly of note. The Phase II effort will focus on the optimization of these primer systems and associated application and activation methods. Water-based systems will also be developed and demonstrated.

Description

We design and develop a Decision Support Tool (DST) that supports On-Demand Special Use Airspace (SUA) scheduling and flight plan optimization around SUA between Airline Operations Control (AOC), Military, Air Traffic Control System Command Center (ATCSCC), and Air Route Traffic Control Center (ARTCC) personnel. The tool allows AOC and ARTCC Traffic Management Unit (TMU) personnel to coordinate strategic and tactical plans, with a strategic look ahead time from days to less than 2 hours, and tactical plans up to the minute centered locally around an ARTCC airspace. The tool coordinates aircraft movement though vs around SUA. The tool allows for asynchronous communication of priorities associated with flight plans and flight plan amendments (contingency plans) between the AOC and ARTCC TMU specialist, allowing the ATCSCC and Military to view these priorities and TMU responses to them at any time. This technology will be developed to Technology Readiness Level (TRL) 2 at the end of Phase I, and TRL 4 prototype system by the end of Phase II.

Description

The objective of this NASA SBIR program is to develop conformal Metal Rubber<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <sup>TM</sup> sensor skins for the distributed measurement of wall shear or skin friction on rotorcraft rotor blades. The sensor skin arrays would allow the direct two-dimensional mapping of both orthogonal components of tangential skin friction on rotor blade surfaces without requiring large recessed cavities within the blade structure. Metal Rubber<sup>TM</sup> skin friction sensor element prototypes have been demonstrated on small laboratory flow test articles. Wall shear measurement data are important to 1) establishing boundary conditions for computational fluid dynamics (CFD) analysis of air vehicle boundary layer flow and turbulence, and 2) active flight control of air platforms. During Phase I, NanoSonic would design, fabricate and test new, large-area Metal Rubber<sup>TM</sup> sensor skin materials and arrays capable of surviving the thermal, mechanical, UV and chemical environment of operational aircraft, and work with NASA and industrial partners to transition the use of such sensor skins to use on rotor blade wind tunnel models. The new high performance Metal Rubber<sup>TM</sup> materials, sensor skin arrays, and data acquisition and signal processing electronics would be evaluated using multiple air and water flow systems at NanoSonic and in wind tunnel facilities at a partner institution.

Description

Over the past decade, the importance of understanding the sources and sinks of carbon dioxide and other greenhouse gases has been recognized. In particular, airborne measurements of CO2 profiles throughout the troposphere and lower stratosphere have provided a great deal of useful information, but the instrumentation used has been restricted to airplane or large stratospheric-type balloon gondola platforms due to the size, weight and power requirements of these instruments. While a more widespread measurement campaign using smaller, less expensive balloon sondes could provide very important data, such an approach has been limited by the lack of suitable instrumentation. In this SBIR program, Southwest Sciences proposes to developed a lightweight, inexpensive greenhouse gas sensor suitable for balloon sonde measurements, yet exhibiting specifications that approach those of the much larger and expensive research instruments used on current airborne platforms. Using a novel ratiometric measurement technique, this sensor will provide dry air mixing ratios of CO2 without the need for concurrent measurements of temperature, pressure or moisture.
