Green Hills Software Helps GE Build World's Most Powerful Jet Engine

Engine produces unprecedented 115,000 pounds of thrust

Santa Barbara, CA. April 8, 2002 -- Green Hills Software, Inc. today announced that GE Aircraft Engines (GEAE), a division of General Electric Company (NYSE: GE), is using Green Hills Software's MULTI® development tools to build the world's most powerful jet aircraft engine. MULTI and its optimizing C compiler will help develop engine control software for the GE90-115B engine, which is rated to produce an unprecedented 115,000 pounds of thrust. The GE90-115B will be used exclusively to power Boeing's long-range 777-200LR and 777-300ER twin-engine aircraft.

GE Aircraft Engine The engines produced by GE Aircraft Engines lead the commercial aviation industry in their respective thrust classes for reliability, maintainability, and affordability. The GE90-115B, a member of the GE90 family of engines, utilizes high-flow swept fan blades to enhance thrust and reduce fuel burn. It also utilizes a high-efficiency, high-pressure compressor to achieve greater torque in the fan mid-shaft than any other jet engine. The GE90-115B first underwent ground tests in November 2001, setting a new record for jet engine power at over 120,000 pounds of thrust. Japan Airlines was the first carrier to select GE90-115B-powered 777-300ERs for its fleet, with delivery slated for 2004.

MULTI and the PowerPC optimizing C compiler were used to develop the engine control software, which runs on a PowerPC processor in the Full-Authority Digital Engine Control (FADEC). The FADEC controls the temperature, speed, airflow and fuel flow of the engine, among other things.

"Green Hills has a long, successful history of supplying development tools to GE Aircraft Engines," said John Carbone, vice president of marketing for Green Hills Software, Inc. "Our easy-to-use MULTI IDE and high-performance PowerPC optimizing compilers have proven themselves in a number of GE engines already, making us a natural for this project. We are delighted to be working with GEAE to build the world's most powerful jet aircraft engine."

MULTI, together with Green Hills' family of optimizing C, C++, EC++, and Ada95 compilers, automates all aspects of embedded software development. Featuring a window-oriented editor, source-level debugger, graphical program builder, and run-time error checker, MULTI also includes a version control system, instruction set simulator, performance profiler, and real-time EventAnalyzer™.

MULTI is available for major 32-bit and 64-bit RISC and CISC CPUs, as well as a number of popular DSPs. MULTI supports a variety of host/target connectivity options, including BDM and JTAG OCD (On-Chip Debugging) solutions, EST's visionICE, Agilent's Processor Probe, ARM's EmbeddedICE, and various ROM Monitors. MULTI also supports the Green Hills Probe™, the industry's fastest and most intelligent hardware debug probe for 32-bit, 64-bit, and multiprocessor SoC embedded systems.
