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.
