This proposal aims to develop a predictive model for characterizing Hydroxyl Terminated PolyButadiene (HTPB) polymer binder resin, used in existing and emerging solid rocket motors. The model will use modern analytical methods to correlate HTPB polymer system chemical and physical characteristics with gum-stock and formulation end-use properties. The objective is to produce a reliable HTPB variant ...

Calcium lanthanum sulfide is an infrared transparent ceramic with many desired properties including its high temperature optical and mechanical properties and its potential use in designing new multi-band optical components.  However current production methods for calcium lanthanum sulfide are relatively immature and often contain impurities that limit optical performance of the produced powders. ...

Propellant formulations used in solid rocket motors contain highly energetic materials which employ stabilizers to protect the polymeric structure of these propellants. The stabilizer content changes with age and other environmental factors causing the propellant to become increasingly unstable with the potential to self-ignite. Therefore, there is a need to detect the stabilizer content present i ...

TRI Austin will demonstrate that the volumetric heating response of reinforcing SiC fibers and carbon fibers (CFs) can be utilized for processing SiC-SiC and SiC-C composites using the polymer infiltration and pyrolysis (PIP) method. Volumetric heating methods allow for more uniform and out-of-furnace processing of ceramic matrix composites (CMCs). Although preceramic polymers have low electrical ...

The Navy has a requirement to detect when GPS navigation systems are being jammed or spoofed and to calculate an Angle Of Arrival from the navy platform location to the threat transmitter location. UHU Technologies has developed a capability for commercial applications that generally meets this Navy requirement, but not at the performance levels specified by the Navy. This study is to investigate ...

The current Anti-Personnel Obstacle Breaching System (APOBS) consists of grenades, equally spaced on a fabric reinforced detonating cord over-braided in a polyester support structure. The APOBS kit contains 45-meters of line charge, a rocket motor to propel the system over the target, and a drogue chute to ensure straight-line deployment. Currently the launch rod for the APOBS rocket is installed ...

TransWave Photonics proposes to develop a high-power quantum cascade laser emitting near 4.6 um with > 65 W average power and 35% wall-plug efficiency under quasi-continuous wave operation at operating temperature of > 30 °C. Using an optimized active region and cooling system design, we expect that the device should exhibit low thermal resistance and high effective thermal conductivity of a heat ...

Aircraft Non-Cooperative Target Recognition (NCTR) is a method for assessing the threatfulness of aircraft within a dense surveillance space at long range. The fusion of measurements from multiple radar modes facilitates the determination of a comprehensive set of target characteristics such that a more informed assessment of a target’s threat level can be made.  The inclusion of surveillance m ...

The Navy’s Naval Sea Systems Command (NAVSEA) has the need to be able to immediately identify unmanned airborne systems (UAS) of interest while understanding their environments. Some UAS of interest are lacking in diverse exemplary images both in term of point of view and environment. Furthermore, visible images alone may be insufficient to achieve NAVSEA’s performance targets, necessitating t ...

Marine aluminum structures across different Navy platforms are prone to cracking, particularly in aluminum hulls. Repairing these cracks by traditional means is costly and time-consuming, and the Navy needs an adaptable and durable solution that can be applied underwater without dry docking the vessel. To address this need, the Texas Research Institute Austin (TRI Austin) proposes an applied resea ...
