WEB-BASED TRAINING ON HEREDITARY HEMOCHROMATOSIS

Not Available The objective of the proposed effort is to demonstrate the feasibility of manufacturing an ultra compact, silicon carbide heat exchanger for heat recovered gas turbine engines. The use of silicon carbide allows recuperator design temperatures of 1000-1200 degrees Celsius that capitalize on the inlet temperature capabilities of advance gas turbine designs. Higher thermal efficiency, improved fuel economy and greater power density are the benefits to be realized. In Phase I, Busek Co. Inc. and our development partner Allison Engineering Co. will evaluate candidate gas turbine applications and prepare a conceptual design of the heat exchanger that is amenable to direct reaction bonding of sintered alpha silicon carbide. We will prepare a number of material specimens and test modules that incorporate all the thermo-structural features or the prototype HEX to be designed and fabricated in Phase II. The test specimen properties will be evaluated in Phase I to demonstrate manufacturing feasibility. In Phase II Busek and Allison will design and fabricate a hybrid size prototype heat exchanger using manufacturing methods developed in the Phase I program. The recuperator will be tested in a test facility at Allison specifically designed for gas turbine heat exchanger evaluation. BENEFITS: Improved fuel economy, efficiency and low cost will allow gas turbines to be considered for prime movers, automotive and emerging hybrid vehicle applications.
