Not Available High power motors and generators can be made very compact when run under cryogenic conditions. For further enhancements in power densities it is highly desirable to use High Temperature Superconductors with a greatly enhanced critical current densigy Jc at 3T at 77K, which would allow the use of liquid nitrogen as a coolant. Under these operating conditions the superconductor YBa2Cu ...

Not Available Long-range, non-cooperative identification techniques such as one-dimensional shape echoes require sources that are compact, eyesafe and produce temporally short pulses to provide fast accurate target identification in the field. To meet these requirements, CTI proposes a solid state Raman laser (SSRL) with an innovative architecture that produces 1.5 um output in short 1 ns length ...

Not Available The goal of this Phase I research is to design, fabricate, and test a high-effeciency, low-power, two-phase pumped loop. This high-efficiency, low-power, two-phase pumped loop will use a unique two-phase working fluid pair that offers the capability of higher efficiency and lower pumping power becuase of its heat of solution characteristic. This heat of solution characteristic, comb ...

Not Available This research project will result in the development of a cost analysis tool used for critical design trades early in the development process of new systems. The tool will enable the engineer, analyst, scientiest, or system planner to conduct life-cycle cost evaluations duringthe development process. The cost evaluations will contribute to effective design trades ensuring integral a ...

Not Available The high performance, high power density combustors being proposed for IHPTET III must operate without exhinbintng combustion instability. There is a need to develop a time-accurate CFD combustion dynamics code that provides improved understanding of the acoustic/heat-release coupling and is able t predict the frequency and limit cycle of the instability. The code also needs to be p ...

Not Available Virtually every user of launch services is seeking methods to reduce launch costs. A reusable conventional launch vehicle configuration shows the potential to achieve this goal. The LOX/LNG propellant combination shows the potential to enhance both propulsion system reusability and launch system mass-to-orbit capability. This propellant combination also has the performance margins n ...
