This paper describes progress on Westinghouse’s Advanced Turbine Systems (ATS) Program. The ATS Program objective is to develop new utility gas turbines with greater than 60% net plant thermal efficiency, NOx emissions limited to less than 10 parts per million, reduced cost of electricity generation by 10% over current systems, and reliability-availability-maintainability equivalent to modern power generation systems. The Westinghouse ATS plant is a highly efficient combined cycle, based on an advanced gas turbine incorporating novel design concepts and enhancements of existing technologies. The 501 ATS engine is a fuel-flexible design operating on natural gas with provisions for future conversion to coal or biomass fuels. It is based on proven concepts employed in Westinghouse 501F and 501G engines. To achieve the required performance and reliability, the engine utilizes closed-loop steam cooling, advanced materials and coatings, and enhanced component performance. To minimize NOx emissions, an ultra-low NOx combustion system was incorporated. To ensure success, the necessary technologies were developed and integrated into the ATS engine design.

Industrial Gas Turbine

The development of a dry, low-emissions combustor for the AlliedSignal Model ASE120 industrial gas turbine engine is in progress. The combustor is designed to provide 10MW of engine power output and also meet all current exhaust emissions requirements. The combustion system has a single-stage premixer and a novel, yet simple, variable geometry to control the flame temperature over the entire operating range of the ASE120 gas turbine engine. Design concepts of this lean premix-prevaporize combustor operating on air staging technology are presented. Preliminary results from computational fluid dynamics (CFD) analyses of the system are discussed.

Abstract Computer-aided engineering is traditionally employed to evaluate existing engine designs or very mature designs for which detailed design information exists. The analyses are performed to validate and fine tune one design rather than exploring widely differing design concepts. Thus, these analyses are often performed only after a significant commitment has been made to a particular engine design. Computer-aided engineering, however, also has the potential for providing estimates of engine performance at the very onset of the engine design cycle. Such up-front estimates may then be used to lead the design process and to allow conceptually different engine designs to be quickly assessed. For instance, up-front estimates of engine vibration and forces transmitted through engine mounts would support target cascading of engine related noise and vibration requirements at the onset of the design cycle. The objective of this paper is to review the formulation of a simulation tool to support up-front engine design for noise and vibration. This tool provides estimates of important engine noise and vibration measures based only upon a conceptual engine design. Major components of the engine model include a rigid engine block, a flexible crankshaft with hydrodynamic bearings, torsional and bending modes, and nonlinear (frequency/load dependent) engine mounts. The formulation of this model is detailed herein and sample results are reviewed for one engine design.

Immersion Type

With the introduction of field-emission sources and “immersion-type” objective lenses, the resolution obtainable with modern scanning electron microscopes is approaching that obtainable in STEM and TEM-but only with specific types of specimens. Bulk specimens still suffer from the restrictions imposed by internal scattering and the need to be conducting. Advances in coating techniques have largely overcome these problems but for a sizeable body of specimens, the restrictions imposed by coating are unacceptable.For such specimens, low voltage operation, with its low beam penetration and freedom from charging artifacts, is the method of choice.Unfortunately the technical dificulties in producing an electron beam sufficiently small and of sufficient intensity are considerably greater at low beam energies — so much so that a radical reevaluation of convential design concepts is needed.The probe diameter is usually given by

Technological Products

An accurate understanding of users' needs is essential for the development of innovative products. This article presents an exploratory method of user centered research in the context of the design process of technological products, conceived from the demands of a large information technology company. The method is oriented - but not restricted - to the initial stages of the product development process, and uses low-resolution prototypes and simulations of interactions, allowing users to imagine themselves in a future context through fictitious environments and scenarios in the ambit of ideation. The method is effective in identifying the requirements of the experience related to the product’s usage and allows rapid iteration on existing assumptions and greater exploration of design concepts that emerge throughout the investigation.
