Coal-fired integrated gasification combined-cycle (IGCC) power plants need to be able to increase their power outputs during peak demand periods without increasing CO2 emissions to improve power grid quality and increase power grid security. We propose to develop a compact, low-cost combined thermal and CO2 storage system. This system can not only directly increase the plant power outp ...

The oscillating water column (OWC) is a candidate technology for the economical recovery of the projected 17.5 x 1012 kW-hr energy that is available from the world¿s oceans. While the relative dynamics between the OWC system and the incident water waves are mathematically understood, computational solutions have not been used to ¿tune¿ the OWC turbine-generator sub-systems to operate where the ...

Airborne directed energy weapons offer advantages over conventional weapons as they minimize collateral damage, reducing the cost of post-conflict reconstruction. However, the high power levels required by these weapons present size and weight challenges for airborne applications. In particular, the current capacity required of the power transmission cables can make the power transmission system o ...

Titanium alloys are desirable for high performance military systems due to their excellent strength-to-weight ratio and their ability to withstand high temperatures.  However, titanium alloys cannot be machined rapidly due to their low thermal conductivity and high strength.  These factors render titanium alloys difficult and costly to machine.  New manufacturing technologies are needed to redu ...

We propose to combine Purdue University’s expertise in the area of nano-scale antennae with QmagiQ’s Qwip technology to develop a new class of polarimetric longwave infrared focal plane arrays (FPAs). The Phase 1 effort will pave the way toward the development in Phase 2 of dual-band polarimetric FPAs producing simultaneous imagery in two spectral bands with polarization discrimination capabi ...

3He offers over three orders of magnitude difference between the ortho-and para-spin states in its absorption cross section for epithermal neutrons. Polarized 3He cells serve as neutron spin filters for preparation of intense beams of polarized neutrons, and as spin analyzers for determining polarization of scattered neutrons. While super-mirrors offer an alternative, cells of polarized 3He are fa ...

The objective of the proposed effort is to develop a systematic approach for building reduced-order models (nonlinear coupled finite-degree-of-freedom equations) capable of reliably modeling and predicting limit cycle oscillations (LCOs) and using these models in LCO management procedures. The models will be developed by combining (a) physical observations from ground vibration, wind tunnel, and ...

Hearing protection for personnel working in high-noise environments presents an important challenge for the scientific and engineering community. Air Force maintenance personnel working in close proximity to operating jet aircraft can be exposed to sound levels approaching 150 dBA. At these levels, the attenuation provided by hearing protection devices (HPDs) is limited by bone-conducted sound th ...

We propose to embed quantum dots in resonant optical cavities to sharpen their spectral respone and provide a mechanism to spatially vary it across an infrared detector array. This project will combine the self-assembled-quantum-dot epitaxy expertise of Professor Towe's group at Carnegie Mellon University with the infrared focal plane array design, fabrication, and test expertise of QmagiQ. Phas ...
