Download Tiff (971k)	Aircraft Engine Combustor Simulation The Low NOx Combustion team was awarded a Turning Goals Into Reality Award for demonstrating a total NOx emissions reduction of 50% from the 1996 International Civil Aviation Organization standards for large and regional size subsonic engines. New engines with this technology are expected to start entering into service in the year 2002. The final goal is to reduce the NOx emissions by a factor of 3 (or 70% reduction) from 1996 levels.

Download Tiff (3.3M)	Multiclustering using Load Sharing Facility (LSF) At the Glenn Research Center, the Space-Time Conservation Element and Solution Element (CE/SE) Method is currently being applied to large-scale numerical flow s imulation in chemically reacting flows and computational aeroacoustics (CAA).
Download Tiff (5.0M)	NASA Glenn Aeroshark Cluster The Pentium III Aeroshark cluster is a network of 64 compute nodes (128 CPUs. Each node has two network interfaces; one for message passing traffic, and the other for disk and system I/O. The cluster is used to execute significant turbomachinery simulations in a production mode.
	NASA Glenn Power Grid Challenge The Multifidelity Engine Model consists of CORBA analysis elements that simulate the high pressure compressor/combustor/turbine subsystem coupled with the low pressure compress or/turbine subsystem of a turbine engine.
	Numerical Propulsion System Simulation The Numerical Propulsion System Simulation (NPSS) is developing an object orient ed framework for Aerospace Propulsion with the integration of multiple disciplin es such as aerodynamics, structure, and heat transfer with numerical zooming on component codes.
	Wrapping Legacy Scientific Applications A distributed object is a reusable, self-contained piece of software that cooper ates with objects in a plug-and-play fashion. Many scientific applications in a erodynamics and solid mechanics are written in Fortran. Refitting these legacy Fortran codes with distributed objects can increase the code reusability. At the Glenn Research Center, we are developing efficient technologies and tools to integrate aerospace applications into a distributed object framework. These three figures show different wrapping techniques (developed by J. Sang, C. Kim and I . Lopez.)
