Ground-based space telescope imaging contends with atmospheric turbulence that distorts imagery. Adaptive optics (AO) mitigate these effects. Deconvolution is needed because of residual distortions and because AO is not always available. When considering

Production of hydroxylamine nitrate (HAN) and hydroxyethyl hydrazine nitrate (HEHN) is of great concern for the manufacture of AF-315E. Current stockpiles of heritage ingredients held by AFRL are being depleted and those manufacturers are no longer in exi

Current and future explosive munition weapon systems development relies heavily on explosives detonation performance characterization and computational hydro-code simulation research conducted by DoD and DoE research communities. This work in turn relies

This proposed Phase II sequential effort will build upon the Phase I and original Phase II programs by: 1) Supporting AFRL's ongoing flight experiment of Oscillating Heat Pipe (OHP) chip carriers to evaluate their compatibility with and performance in a space environment; 2) Expanding the OHP operating limits and steady-state performance models to further improve the predictability (and perceived ...

Based on successful Phase I feasibility prototype results, this Phase II SBIR project shall develop Long-Distance Oscillating Heat Pipe (LD-OHP) heat transporters for high power, high temperature and low thermal resistance thermal management of solid state power amplifiers (SSPAs) in current- and next-generation spacecraft. The LD-OHP technology initially demonstrated in Phase I and to be more ful ...

This Phase II STTR effort is focused on generating the data necessary to identify the phenomenology that produces carbon deposition within kerosene film cooled rocket engines.This data is essential to guide the model development and validation process.Program outputs will be both data and a physics-based model for carbon deposition.

ABSTRACT: High Energy X-ray computed tomography (CT) is used to inspect the integrity of solid rocket motors. The purpose of this proposal is to improve the detection of defects when they are obscured due to physical limitations of CT. Lickenbrock has developed an advanced variant of the expectation-maximization (EM) algorithm, and other algorithms, for improving fidelity of CT. The EM algorit ...

ABSTRACT: Flow Modeling and Simulation, LLC (FMS), proposes to develop a computational software tool, herein designated AUG3D, that is intended to provide physics-based, multi-level, validated computational simulations of turbine engine component flow fields, particularly those associated with thrust augmentors, i.e., afterburners. This tool will be ideally suited for closely integrating physica ...

ABSTRACT: Under this Small Business Technology Transfer (STTR) program, Innovative Technology Applications Company (ITAC), LLC and the University of Notre Dame (UND) are working to develop new optical instruments that will enable nonintrusive, off-body measurements of flow parameters in hypersonic flight. The two concepts under development by the ITAC/UND team and described in this proposal invo ...

ABSTRACT: The SCRAMSIM computer code will be able to perform analysis for engineering design, stemming from a low order Reynolds Average Navier-Stokes (RANS) to high order (4th or higher) LES using accurate subgrid scale models (SGS). It will also solve thermal non-equilibrium mechanisms, conjugated heat transfer, general finite-rate chemistry using several databases for hydrocarbon/hydrogen-air ...
