This is a preliminary exploration of design problems and expected performance of compact combined cycle engines for transportation applications consisting of an intercooled gas turbine as topping unit and a Rankine cycle as bottoming unit. The latter must take all or most of the required vaporizer heat from that rejected by the intercoolers and/or other flowpath coolers. Water is rejected as the ...

A feasibility analysis of a modified Naval engine with both water extraction and water injection is proposed. The modifications would implement the Regenerative Feedback Turbine Engine (RFrE), invented by Coleman Engine Corporation as a method of achieving high efficiency over a broad power range while reducing emissions significantly and, very important for a multi-deck ship, reducing the flow o ...

The goal of this investigation is to develop the invasin gene as a vaccine against M. tuberculosishuman host. Up to the present time, the only known and generally accepted vaccine-BCG-is a living athas shown variable efficacy in the countries where it has been used. Although efforts by other invesof obtaining non-viable vaccine have not proved successful, the concept of a new candidate vaccine cpr ...

Mycobacteria multiply in macrophages. Previous work has indicated that inhibition of TGF-beta produlimit the growth of intracellular pathogens including M. avium. This project will examine the potentantagonists to affect the growth of M. tuberculosis (Mtb) in human macrophages. Studies will includeselected antagonists in combination with cytokines and the use of antagonists in vivo to limit infecm ...

An evaporative spray cooled Switched Reluctance Motor with integral drive electronics is proposed. The motivation is to increase power density, efficiency and reliability through improved thermal management. A concept is presented in which all components are contained within a machine frame. The gravity independence and heat transfer efficiency of spray cooling permits the elimination of large ...

This SBIR Phase I project will investigate an integration framework to enable the virtual prototyping of mechanical components, specifically for application to ISR's advanced spray cooling technology. The framework will accommodate an Automated Design, Analysis, and Manufacturing system currently under development at ISR by allowing the integration of advanced parametric CAD utilities, a suite of ...
