In this effort, tOSC and the University of New Mexico COSMIAC (Configurable Space Microsystems Innovation Applications Center) will combine to generate a Target-in-the-Loop (TIL) system concept that can simultaneously measure the strength of atmospheric turbulence and scintillation, as well as the refractivity occurring at the measurement time. For this system concept, we will leverage existing tO ...

Current scene projection hardware is challenged to simultaneously meet the requirements for high peak temperature (> 2000K), high resolution (> 1Kx1K), response time < 1 ms, cryogenic and temporally uniform photon flux. MEMS, Resistor arrays, liquid crystals, and photonic crystals all suffer in one or more areas. MEMS suffer from flicker and low dynamic range. Resistor arrays suffer from low frame ...

Experimental data from a number of DoD supported research programs have indicated that electrical systems capable of producing highly repetitive bursts of high voltage, fast risetime pulses are a critical enabling technology for applications tied to nonequilibrium physical processes, such as combustion, boundary layer flow, and the generation of high power EM waves. Recognizing the important role ...

Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of problems and challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal and/or catalytic cracking of hydrocarbon fuels is always accompanied with coke formation. Coke deposits on combustor and nozzle walls reduce heat ...

Oceanit proposes to first is to use radiative transfer techniques pioneered for astrophysics, instead of Monte Carlo simulation. In particular, we used a variant of the Bohm-Vitense method, which expresses the solution as a weighted sum of basis functions, allowing us to convert the radiative transfer equation into a set of linear equations that we can solve with standard linear algebra methods. S ...

Engines will be getting smaller and hotter for efficiency reasons, requiring novel sensors with extended and enhanced performance. Emerging fiber-optic sensing approaches could provide a unique solution to the widening technology gap between next-gen engine requirements and conventional sensors limited capabilities. The overall objective of this program is to develop techniques to integrate new pr ...

Theoretical studies have shown that the electrical current in a CNT Field Effect Transistor (CFET) is intrinsically linear. Inherently linear CNTs offer significant improvements in performance without sacrificing power and have the potential for greatly improving range and sensitivity in state-of-the-art receivers such as those used in satellite systems and other communications applicationsModelin ...

High-pressure turbulent combustion occurs in many combustion devices critical to the Air Force. Notwithstanding significant progress in computational modeling of these devices; several challenges have remained. A fundamental challenge is identification of reaction pathways and reactions in small molecule foundational chemical kinetics requiring improvements under these high-pressure turbulent cond ...

Carbon nanotubes (CNTs) have great potential for high performance RF applications. Theoretical study has shown that the electrical current in a CNT field effect transistor (CFET) is intrinsically linear. Today, linearity is the underlying limitation in increasing the data transport densities of wireless networks. The complex modulation protocols used to achieve higher data rates requires linear am ...

Adaptive Optics allow ground-based astronomical observatories to overcome atmospheric distortion limited observation by using natural and artificial guide stars to measure the distortion. Sodium-layer guide stars provide near all-sky coverage for high resolution astronomy. Over the last 20 years, Optically Pumped Semiconductor Laser (OPSL), also referred to as Vertically Extended Cavity Surface Em ...
