The goal of this program is to design a lightweight optical bench capable of remaining stable under temperature and moisture changes, while isolating the precision optical array from vibrations such as engine noise and air turbulence. By integrating a customizable periodic stack in the bench, vibrations are attenuated more effectively than commercially available mounts. Additionally, the periodic ...

Advanced turbomachinery components play a critical role in launch vehicle and spacecraft liquid rocket propulsion systems. To achieve desired efficiencies, extremely tight tolerances are often imposed between inducer blades and shrouds or other system components which sets up strong interactions that influence both the aerodynamics and the structural performance of blades and vanes. These transien ...

Chemical contamination of spacecraft components as well as thermal and force loading from firing liquid propellant thrusters are critical concerns for in-space propulsion applications. Gas molecular contamination and liquid droplet deposition due to incomplete combustion threaten to damage surface materials, sensitive instruments and optical sensors, and poses major risks for mission success. Liqu ...

The objective of the overall STTR program is to develop a high performance mid-format dual band long wave infrared (IR) focal plane array (FPA) using p-type InAs/(In)GaSb strained layer superlattices (SLS). The project consists of three primary research thrusts including (1) improvement of quantum efficiency, (2) optimized sidewall passivation, and (3) focal plane array fabrication and testing. ...

Thermally induced fatigue and residual stress introduced during fabrication are sources of failure in microelectronics, which raises reliability concerns for MDA and its system integrators. CFDRC has teamed with experts in the reliability of microelectronics packaging to develop a physics based modeling and testing protocol to correlate material properties and thermal loading conditions to stress ...

The US congress has instructed NASA to include a lander component in the next Europa mission. The mission has a target launch date of 2022, and its primary goal will be to search Europa?s icy surface for evidence of life that may persist within the ice shell or subsurface ocean. The Europa lander study specifically recommends a combination of a mass spectrometer and a Raman spectrometer to investi ...

GTL?s SNS technology aids in the operation of new or existing structural health monitoring (SHM) systems by integrating data and power pathways into the structure. The use of this technology within a composite structure would allow engineers to place sensors from an SHM system directly where they are needed on a structure with instant power. GTL?s SNS technology offers the potential for developers ...

NASA recognizes the importance of conservation, smart utilization and reuse of resources for their deep space missions to address the need for regeneration of air, water and waste with highly reliable systems to reduce mission payload. Additionally, energy for life support and other systems needs to be obtained from renewable energy sources or waste streams. In order to address NASA's requirements ...

We propose that the key to robotic automation in unstructured environments is compliant robotic manipulators that can tolerate, sense, and leverage contact in a feedback loop. We will demonstrate an instrumented end-effector that will be capable of enhanced perception through observed and controlled contact. This approach requires: (i) a network of sensors capable of capturing the highly compliant ...

DEC-Shield technology offers the means to generate electric power from cosmic radiation sources and fuse dissimilar systems and functionality into a structural component to create a Multi-functional Structure (MFS). DEC-Shield integrated into MFS technology can be used to generate electric power and provide radiation protection in a space vehicle; even maximizing that protection by spreading the ...
