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

The primary objective of this project is to improve the efficiency of large-format mid-wave infrared (MWIR) and long-wave infrared (LWIR) light emitting diode (LED) arrays for infrared scene projector applications. While LED technologies have shown great

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 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: Softronics Ltd. proposes to implement an advanced VLF receiver front end utilizing a trio of advanced technologies. The first is a digital cancellation DSP technique that reduces both atmospheric noise and jamming signals within the desired passband, significantly improving the SNR of the VLF signal. The second is a unique component technology and topology that offers extraordinary VL ...

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: 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 ...

The objective of this Phase-II research effort is to build and deliver a fully operational fiber-coupled picosecond (ps) laser-based CARS system for measuring gas-phase temperature in reacting flows. The proposed fiber-based CARS system will also be fully capable of nanosecond operation with the addition of a nanosecond pump laser provided by the customer. It will be tested in laboratory hydroca ...

The goal of this SBIR is the enhancement of the current state-of-the-art combustion instability analysis tools.  The planned enhancement is focused on capturing the effects of injection element distribution and the inclusion of substantial film cooling and diluent injection.  These characteristics are extremely important in the design of high-pressure oxygen rich staged combustion (ORSC) engines ...

The European Union''s RoHS and WEE Directives mandated the elimination of the carcinogenic, hexavalent chromium coatings for metals, including magnesium and zinc-nickel plated substrates.  The purpose of this project is to find chemistry that will meet requirements of industry performance specifications and of the mandate.  METALAST intends to explore trivalent chromium in conjunction with two o ...
