HTF7000 Reaches One Million Hours On Bombardier Challenger 300

Honeywell Claims Engine Delivers 99.96 Percent Reliability

The fleet of Honeywell Aerospace HTF7000 turbofan engines has accrued more than one million hours of operation on the Bombardier Challenger 300 and is delivering more than 99.96 reliability for operators, according to the company.

The HTF7000 exclusively powers the Bombardier Challenger 300, a business jet capable of flying nonstop from New York to London at 0.80 Mach under certain operating conditions. There are more than three hundred Bombardier Challenger 300 aircraft in service with corporate and private operators and in Bombardier's Flexjet fractional ownership program.

"Planned with years of industry input from customer advisory boards, steering committees and surveys, along with Honeywell.s expertise in the business aviation propulsion market, the HTF7000 is one of the most reliable, fuel efficient and low-cost engines in business aviation today," said Rob Wilson, President, Business and General Aviation, Honeywell Aerospace. "With one million hours of service and counting, the HTF7000 has a dispatch reliability rate in excess of 99.96 percent and an in-flight shut down rate of less than .004 percent."

Development of the HTF7000 began in 1998 to answer demand for a turbofan engine with extremely high reliability and very low operational costs. Customer interest in features such as access to all the main shaft bearings and on-wing combustors drove a significant portion of the ultimate design of the engine. The HTF7000 received FAA certification in June 2002 and JAA validation in December 2002.

"We are extremely pleased to mark this milestone on such a reliable and productive power plant for our most popular Challenger 300 business jet," said Michel Ouellette, Vice President and General Manager, Challenger Aircraft. "Durability and performance are key requirements when first choosing an engine for one of our business aircraft platforms. The HTF7000 clearly performs to the required specifications and also is easily supported in the field by our Aircraft Service Centers."

The HTF7000 produces approximately 7,000 pounds of thrust at takeoff, with a flat rating of 86 degrees Fahrenheit (ISA +15¡ÆC), allowing the Bombardier Challenger 300 to fly transcontinental missions up to 3,100 nautical miles (5,741 km) with eight passengers, two-crew and maximum allowable fuel under certain operating conditions.

The HTF7000 design incorporated green technologies from the onset, including reductions in fuel burn, resulting in lower carbon dioxide emissions, reduced operational costs and best-in-class noise levels with the smallest noise footprint. Later this year, Honeywell says it will incorporate improved green technology for its HTF7000 family. Honeywell.s Single Annular comBustor for Emissions Reduction (SABER) will enable emissions savings of up to 25 percent less than current levels. Fielded HTF7000.s will be able to be retrofitted with SABER technology, and it will be included in new engine deliveries for all aircraft powered by the most dependable engine in the 7,000-pound thrust class.
