Pratt & Whitney Canada Launches Enhanced PW308C Engine for Dassault's Falcon 2000S

GENEVA, Switzerland, Monday, May 16, 2011

PW308C engine derivative, includes the state-of-the-art TALON II™ (Technology for Advanced Low NOx) combustor, which provides major reductions in NOx and smoke emissions, and maintains excellent engine starting characteristics

Pratt & Whitney Canada (P&WC) has launched an enhanced PW308C engine for Dassault's new Falcon 2000S business jet. The engine upgrade, which will bring improved environmental performance for the PW308C, is currently undergoing validation testing in preparation for certification in 2012. P&WC is a United Technologies Corp. (NYSE:UTX) company.

"This marks yet another milestone in our relationship with Dassault," said Michael Perodeau, vice president, Marketing, Corporate Aviation and Military Programs, P&WC. "In keeping with P&WC's green-engine philosophy, the PW308C engine includes the state-of-the-art TALON II™ (Technology for Advanced Low NOx) combustor, which provides major reductions in NOx and smoke emissions, and maintains excellent engine starting characteristics."

The enhanced PW308C's first engine run took place in February 2011 and the emission targets were achieved with margin. Certification is slated to take place within the next year.

With product improvements to the combustion and fuel delivery systems, the enhanced PW308C engine will have best-in-class engine smoke and emissions performance. Similar to the proven PW307A design, the new PW308C combustor features a high-efficiency, reduced volume, TALON II ™ combustor. The PW308C engine's proven reliability is further reinforced by the durability of the air blast fuel nozzles, which are maintenance free until engine overhaul. The engine satisfies FAA, ICAO and CAEP/6 smoke and emission levels, and meets Zürich class 5 requirements on NOx levels, avoiding certain airport surcharges.

Lowering Emissions

A leader in the green evolution in aerospace, Pratt & Whitney Canada champions environmental stewardship as a core value across all facets of its business. Indeed, Pratt & Whitney Canada has remained focused on designing and building more fuel-efficient engines since it first launched the PT6 engine close to 50 years ago.

P&WC's revolutionary TALON II combustion technology found in the enhanced PW308C reduces emissions while delivering outstanding performance, durability and operating economics. Up to 50 percent reduction in NOx compared to original 1986 ICAO standards has been demonstrated. In the longer term, new technologies are being developed to reduce NOx by 80 percent, benefiting from further combustion and engine performance improvements.

P&WC first launched its TALON II technology demonstrator program in 1999 and it was subsequently developed and certified on the PW307A engine powering the Dassault F7X aircraft. In 2004, the ATFI (Advanced Turbo Fan Integrator) core demonstrator was used to further progress low NOx technology for future applications. In recent years, progress made in computational fluid dynamics prediction, coupled with advanced fuel injector technology, allowed rapid progress to advances in NOx reduction.
