Adaptive control offers an opportunity to fulfill aircraft safety objectives though automated vehicle recovery while maintaining performance and stability requirements in the presence of unknown or varying operating environment. Future aircraft are a natural application of adaptive control. These aircraft will be more fuel efficient, have longer operating ranges though more flexible aircraft struc ...

There are a number of critical telemetry measurements to be monitored under continuous field operation, including temperature data across the reactor chamber and the nozzle, pressure data, neutron flux density and flow rate of the propellant. Real-time monitoring of this data in nuclear thermal engines would greatly improve operational safety and performance, reduce operational costs, and signific ...

This SBIR will study the application of a brain machine interface (BMI) to enable crew to remotely operate and monitor robots from inside a flight vehicle, habitat and/or during an extra-vehicular activity (EVA). The goal is to improve robot operator productivity, situational awareness, and effectiveness. With the application of a BMI technology an astronaut in an extravehicular suit could grea ...

According to the NASA A2.01 topic description titled Materials and Structures for Future Aircraft, "advanced materials and structures technologies are needed in all four of the NASA Fundamental Aeronautics Program research thrusts (Subsonics Fixed Wing, Subsonics Rotary Wing, Supersonics, and Hypersonics) to enable the design and development of advanced future aircraft. Proposals are sought that a ...

The one CFD modeling area that has remained the most challenging, yet most critical to the success of integrated propulsion system simulations, is turbulence modeling. There is a need to develop mid-level CFD models for the interaction of turbulence and chemical reactions that give superior results to the simple models (e.g., Magnussen's Eddy Dissipation Concept), but which do not require the ...

The proposed novel program will use measurements of the high-energy photon output from gamma-ray celestial sources to design a new, unique navigation system. This Gamma-ray source Localization-Induced Navigation and Timing, or "GLINT", concept provides deep-space vehicles the capability for self-navigation based upon measurements from observations of these source signals. In the past, gamma-ray so ...

SVT Associates proposes an novel type II superlattice structure to extend the cutoff wavelength and CBIRD SL photo diode structure with unipolar barriers to suppress dark current of SL detectors grown on GaSb substrate. This InAs/GaSb superlattice material system is capable of infrared detection in MWIR/LWIR spectral range, depending on layer thickness of each superlattice period. The goal of this ...

Recently, resonant-tunneling-diode (RTD) based circuits employing monolithically-integrated RTD on high electron mobility (HEMT) structures have been developed in a number of III-V systems in order to improve operational speed. The main goal of this program is to develop wide temperature-operable radiation hard monolithically-integrated electronics based on wide bandgap III-nitride epitaxial struc ...

There is a continual drive to move electronics out of the "warm box" to their point of use on space platforms. This requires electronics that can operate reliably over a wide range of temperatures and in the presence of radiation. The range of functions needed at various points across a given platform require use of digital, analog and high-voltage circuits, partitioned either independently or in ...

The objective of the proposed research and development work is to create new types of compact, autonomous multi-pulse single-shot explosive-driven power supplies that are capable of producing a series of high voltage and/or high current pulses. These generators can be used in new kinds of warheads and munitions. To provide the best Phase I results we plan to leverage our current work with ferroele ...
