ABSTRACT: Material extrusion 3D printing is an Additive Manufacturing method which utilizes a polymeric monofilanment as a feedstock in the fabrication of 3D objects. The relative simplicity compared to other AM technologies makes it an attractive manufacturing tool, however, characteristics inherent to this 3D printing method (namely air gaps between print rasters) makes it undesirable for the 3D ...

ABSTRACT:The goal of this proposed R & D project is to develop safe, low cost, robust lightweight electrochemical power sources for space launch vehicle upper stages, and flight termination batteries for space launch vehicle first stages. The project specifically addresses a Flight Termination Battery (FTS) that weighs less than 7.0 lbs., another Flight Termination System Battery that weighs less ...

One of the biggest strategic warfare challenges today is a loss of access, as a result of the Anti-Access/Areal Denial (A2/AD) threat posed by our increasingly sophisticated adversaries. Advanced Electronic Warfare (EW) capabilities are a critical element of the A2/AD solution being used in ever evolving combinations to disrupt and exploit adversarial use of the electromagnetic spectrum while prot ...

To enable future robotic exploration systems to have greater mobility capabilities on difficult terrain such as craters, cliffs, gullies, and skylights, Tethers Unlimited proposes to develop the "Advanced Regolith Anchoring for Cable-assisted Mobility" (ARACMO) Anchor. This device can launch hundreds of meters from a rover vehicle, self-right, autonomously anchor, and support high loads through t ...

For computer based systems where time is important, a methodology is proposed which separates applications from architecture. A System is represented graphically in Blueprints, and textually in Formal Models expressed in the Real-time Executable Architecture Language (REAL). The system application and architecture are evolved to work in harmony using the SIMPLEX temporal performance simulation t ...

ABSTRACT:The objective of this solicitation is to develop real-time automatic scaling software for oblique ionograms (OIs). The NWRA team has developed an extensive HF propagation computational tool set, which includes a capability called APEx (Automated Point Extraction) for automatically finding vertical ionogram (VI) traces within an ionogram image. APEx does not require pre-separation of the O ...

The United States Navy is interested nonlinear transmission lines (NLTL) for microwave generation. One key technology in this endeavor is the development of high power radio frequency (HPRF) source driver. During the Phase I, Eagle Harbor Technologies, Inc. (EHT) successfully demonstrated the Navy source driver requirements for adjustable pulse width, output voltage, rise time and pulse repetition ...

High-value bearings are a critical part of the safety, reliability, cost and performance of modern aircraft. A typical passenger jet will have 100 to 175 high-valve bearings costing from $2,500 to $50,000 each for a total aircraft cost of $300,000 to $600,000. All gas turbine engine bearings are inspected at overhaul and typically 30-40% of there are rejected. For each engine overhaul, bearing re ...

Amastan, in collaboration with the University of Connecticut, proposes to produce high temperature phase stable and CMAS resistant coatings of lanthanum magnesium hexaaluminate (LMHA) material as a suitable substitute to YSZ top coat for thermal barrier coating (TBC) applications. In phase I feasibility effort, Amastan demonstrated high temperature (1600 C) phase stable LMHA coatings that are phas ...

This Phase II effort will leverage the existing Standard Space Trainer (SST) Phase III SBIR state-of-the-art research platform to leverage its inherent capabilities as the software engine to support this research effort. The SST has a collection of software that provides development support and a common runtime environment for the use of mission specific plug-ins. This reusable SST Architecture ...
