The Honeywell HTF7000 is a turbofan engine produced by Honeywell Aerospace. Rated in the Шаблон:Cvt range, the HTF7000 is used on the Bombardier Challenger 300/350, Gulfstream G280, Embraer Legacy 500/450 and the Cessna Citation Longitude. Its architecture could be extended for a range of Шаблон:Cvt thrust.[1]
Operational history
The engine was originally designated the AS907, which was changed in 2004 to HTF7000; the AS907 designation is still used for legal and regulatory use.[2] By October 2016, 2.6 million hours had been logged by 1,400 in service engines and it has a 99.9% dispatch reliability rate. Average fuel consumption is about 950 lb. per hour for a 7,765 lbf engine on a G280, to be compared to 875 lb. per hour for a 4,420 lbf TFE731 on a G150.[1] More than 3.5 million flight hours have been logged till October 2017, and the 2,000th engine should be delivered in 2018.[3]
Honeywell maintenance program is $447 for two engines per hour.[4] Borescope inspections extends time between overhaul and some engines have remained installed for up to 10,000 hr.[1] It has line replaceable components installed with hand tools and is designed for condition-based maintenance.[3]
