The design of turbomachinery components is a complex process requiring many steps and hundreds of minute decisions in an iterative process. The design proceeds from engine cycle performance and meanline design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). Design studies may traverse this process many times, with routine tasks performed by engineers in a ...

Superconducting coils are capable of storing considerable amounts of energy. Should a coil quench, due to overheating or exceeding the critical field or current, the stored energy in the coil must be dissipated safely - without endangering personnel or damaging the coil or control systems. In any superconducting coil design, it is essential to design and build the system such that limits of the ...

Keystone and Faraday, working with Large engine OEMs,IBR forging, and airfoil machining suppliers identified the highest cost drivers for the fabrication of IBR components for gas turbine engines for advanced aircraft systems. A Phase I project demonstrated the feasibility of reducing cost in two critical cost areas of IBR fabrication: the application of near-net shape forging methods for reduced ...

Boron has significant potential as a high energy density ingredient in ramjet propellants and fuels. This is due to boron's high heat of combustion and low atomic weight. For a ramjet ducted rocket, theoretical volume specific impulses of 1600- 1800 sec g cm-3 have been reported for a fuel rich boron solid propellant, 45 % greater than the best hydrocarbon composition. Boron's high ignition tem ...

To achieve full turbine blade life in a modern gas turbine engine, it is critically important to measure and manage the state of residual stresses in high stress areas of the blade. Unfortunately there is no affordable, nondestructive technique commercially available to measure residual stresses in complex geometries like the under side platform areas of gas turbine blades. This proposed project w ...

The verification of the primary and secondary grain orientation in directionally solified and single crystal nickel superalloy turbine blades is critically important to ensure quality and to meet the intended engineering requirements in the gas turbine engine. Unfortunately their is no affordable, commercially avaialble, whole-field technique for measuring grain orientations in turbine airfoils. T ...

This proposal addresses AFOSR's task to: "Develop seamless, easy to use, efficient code to calcultate electronic wave functions and potential energy surfaces of molecules and predict kinetic rate constants for reactions a priori." This is a long-unsolved problem, fundamental to chemistry, where quantum chemical methods must be extremely accurate to provide the electronic structure information and ...

The project aims at developing a reliable and responsive electromagnetic launch system. In the proposed concept, a magnetically levitated sled is accelerated to a velocity of 7 km/sec by a high power linear motor system for the launch of samll payloads. A novel design of electromagnetic guide system with real-time feedback stabilizes the trajectory of the sled during acceleration. The launch objec ...

BEAM Co. will partner with University of Berkeley and University of Rochester in an effort of developing liquid crystal materials for broadband tunable spatial and spectral filtering applications targeting a challenging set of operation characteristics including the ability of wide photoinduced Bragg reflection band shift throughout the visible and near IR region of wavelengths, operation at micro ...

Lithium Technology Corporation has developed innovative manufacturing processes for high-rate lithium ion batteries comprising novel methods of current collector tab formation and cell sealing operations. These processes have enabled LTC to sample lithium HEV battery modules to USABC and EUCar and cells to aerospace companies and NASA, which responded favorably to the performance and generally ap ...
