The rotorcraft aerodynamic interaction is a complicated problem and remains an extremely challenging aspect of rotorcraft analysis. This STTR is dedicated to developing a solution for the complicated rotorcraft aerodynamic interaction problem. The Phase I research coupled a state-of-the-art vortex particle method (VPM) with an unstructured Navier-Stokes CFD body surface solver and prototyped a hyb ...

Transphorm proposes to demonstrate a normally off fast high voltage Gallium Nitride power switch solution. The switch would block to 1200V, have a threshold voltage greater than 5 V, and the phase 2 switch will target an on resistance less than 15 ohm-mm and current more than 1 Amp. To accomplish these targets, Transphorm will combine the design requirements of realizing a high (and positive) thre ...

New material systems are required as a result of advanced performance criteria for the next generation destroyer program and other Navy ships. As a part of these requirements there is high demand for high strength structural composites. The objective of the STTR Phase II project is to develop high strength and light weight structural composites utilizing functionalized single-walled carbon nanotub ...

The demands of the solar energy market require the development of advanced photovoltaic technologies. The DOE is seeking to develop organic PV technologies that are more efficient, long lasting and cost competitive to traditional ones. Organic PV (OPVs) have become well recognizedas an important candidate for future solar power products, although their efficiency is not exceeding 6-7%. The overal ...

We need transformational manufacturing technologies for fabrication of nanomaterials for manufacturing batteries and capacitors that will have a huge impact on improving the energy and power density of batteries and capacitors for transportation, energy storage and consumer electronics applications. Development of novel nanomaterials with high energy and power capability and a novel, nontraditiona ...

The objective of this program is to design advanced energetic oxidizers superior to ammonium perchlorate (AP), develop methods for their preparation, and characterize the products. The overall goal of the Phase II program with options is to make the technology ready for commercialization

The US Navy needs the capability to model acoustic propagation in complex ocean environments containing natural or man-made objects. Such accurate modeling requires the solution of the wave equation in the ocean containing scatterers. In the absence of the scatterer, the oceanic waveguide can be assumed to be axially symmetric. This allows certain types of physically valid approximations to be mad ...

Although carbon capture and storage (CCS) technology has received the most attention for its potential to reduce emissions, processes that convert CO2 into a useful product can provide a positive return on investment and not just be an unrecoverable cost. Compared to CCS technology, the potential revenue generated by the use of CO2-based product is likely to grow popular with time while reducing ...

The proposed program addresses the emerging needs for the Navy to have cost effective alternative liquid transportation biofuels. The main objectives are to produce bio-jet and bio-diesel fuels from cellulosic biomass and nonedible bio-oils and demonstrate that they have cost structure and product quality comparable to petroleum based fuels. Novel concepts in processing, reactor design and catalys ...

Bright coherent light sources in the soft x-ray region of the spectrum are useful for a variety of applications of interest to DOE in the basic sciences, nanoscience and biology, and for technological applications. At Free-Electron Laser Facilities, peak power output of the x-ray pulses is enhanced by using a mid-infrared laser pulse instead of a near-infrared pulse. The current front end for mid- ...
