The proliferation of laser based weapons systems has led to the need for laser threat sensor systems that operate over wide spectral range from the visible to infrared and provide sufficient dynamic range to measure the irradiance levels seen in practice. OPTRA, Inc. proposes a solution based on the complementary combination of CMOS readout integrated circuitry and diffractive optics to provide th ...

Although advancements in CFD technology and high performance computing have proven to be effective and reasonably accurate in assessing the hydrodynamic performance of naval vessels, the effort required to develop associated analysis models remains a challenging and time consuming task. Decomposing and manipulating the design geometry for mesh construction, while capturing near-field and far-field ...

We propose to design a high average power Er:Fiber ultrafast laser system which is pumped at 14xxnm, and at the same time solve other problems related to ultrashort pulses in fiber lasers. The advantage of using 14xxnm pumping is the reduction of the standard quantum defect from 37% to 5%, thus greatly reducing the thermal load on the system, which makes it inherently more efficient. We also inten ...

This NAVY Small Business Technology Transfer project is directed toward the development of a novel hydrogen generator that employs nanostructured metal foam catalysts. Special coating and form factor will also be employed to the hydrogen generating materials to ensure the safety of storage and transportation, while maintaining very high packing density compared with conventional powder packing.

The primary goal of this STTR program is to develop high fidelity LDLP software module that can predict stiffness and damping forces over the ranges of amplitude, frequency, and temperature appropriate for comprehensive modeling of helicopters. The LDLP module will focus on enabling accurate prediction of the onset of both air and ground resonance, as well as the fatigue loads that would arise due ...

The promise of printed electronics can not be realized without high-speed manufacturing processes to drive the cost down for wide spread distribution. This proposal will outline the key points for rapid manufacturing of new electronic devices and systems and make recommendations for making them a reality. There are two main focus areas that encompass all the limitations to printed integrated circu ...

Waste heat from Naval diesel generators provides significant opportunity to introduce organic Rankine cycles (ORC) to increase their fuel efficiency. The objective of the proposed effort is to design and demonstrate a high-speed, spinning scroll expander (HiSSSE) ORC as a power dense waste heat recovery system for diesel generators on ships. The system will leverage Air Squared’s spinning scroll ...

Physical Sciences Inc. (PSI), in collaboration with Sandia National Laboratories, proposes to develop a high energy density (HED) power source based on the principles of thermophotovoltaics (TPV). The core technology of the HED power source is a novel high-temperature, spectrally-selective metamaterial emitter with a tailored emission spectrum matched to the external quantum efficiency spectrum of ...

Additive manufacturing is a disruptive new manufacturing paradigm that hold tremendous potential for creation of novel designs and introduction of novel new alloy systems. However, much of this potential remains unrealized due to a lack of robust material properties databases. Accurate calibration of materials models and robust part qualification and certification regimes both will require massive ...

This Phase II effort will establish stretchable photovoltaic modules that achieve the key metrics of the program: modules with efficiencies > 10%, that sustain elastic deformations > 10% (with little or no loss in performance), and that produce output voltages > 25 V. In this Phase II effort will we demonstrate functional modules deployed on the airfoil of micro unmanned aerial vehicles (MAVs). To ...
