Supercritical CO2 power cycles are being developed for both utility-scaled power generation applications, as well as smaller waste heat recovery applications. Supercritical CO2 cycles are more efficient than current cycles, and the associated turbomachinery components are significantly smaller than that for current steam turbine-based power generation. However, sCO2 cycles operate at a combination ...

Several automotive industry changes are leading to the need for wide-range, high-boost turbocharging systems. Engine emission requirements require good turbocharger performance over a very wide range of flow rates. Trends in engine downsizing require turbochargers to have both good high flow performance, and good low flow performance, to cover a wide range of engine rpm operation. Current methods ...

This proposal would develop the next generation of interconnects and assembly technology by making use of Quilt Packing® (QP) interconnects for the integration of semiconductor chips to extend systems into the third dimension. Quilt Packaging is a unique and versatile edge- interconnect technology that utilizes “nodule” structures extending out from the vertical facets along the edges of QP-p ...

According to a 2014 study commissioned by the Department of Energy, hydropower from the more than 3 million untapped streams in the U.S. could potentially generate 65 gigawatts of electricity and help to reduce greenhouse gas emissions and pollution. However, the development of hydropower has been limited by several obstacles, as described by the U.S. Geological Survey: most of the prime locations ...

Optical limiters (OL) protect sensitive optical and electronic devices from laser-induced damage. The existing passive OL utilize nonlinear optical materials transmitting low-intensity light, while blocking laser radiation with intensity exceeding certain limiting threshold (LT). The common problem with the existing OL is that, at any particular frequency range, the choice of suitable nonlinear ...

Wolf is developing a new technology for reducing glare near the Sun for daylight satellite tracking operations, dramatically reducing the exclusion angle around the Sun. The technology will also prevent saturation of the camera sensor and will preserve a

The primary objectives of the proposed effort are to enhance, expand, and validate a variable-fidelity transient multi-domain software toolset called ATTMO+ for predicting and analyzing the dynamic interactions at a mission-level timescale between electri

Engineering of the next generation of aerospace systems will require investigation into novel propulsion architectures that are designed with consideration of the power and thermal management systems.This will require exploration of the early stage design trade space with hundreds of factors and millions of possible architectures.To enable rapid exploration of this space, PC Krause and Associates ...

Modern military aircraft have major thermal challenges as a result of significant increases to on-board heat generation combined with reduced ability to transfer heat to the ambient environment.Adaptive power and thermal management systems are being explored to mitigate the thermal restrictions. These systems rely on fuel as a primary heat sink but analysis of system performance is based on standa ...
