Honeywell HTF7000

The HTF7000 is a turbofan engine produced by Honeywell Aerospace, rated at roughly 6,540 to 7,624 pounds of thrust. It was originally designated the AS907, renamed HTF7000 in 2004, although AS907 is still used for legal and regulatory purposes. It powers the Bombardier Challenger 300 and 350, the Gulfstream G280, the Embraer Legacy 500 and 450 and the Cessna Citation Longitude, with variants such as the HTF7250G, HTF7350, HTF7500E and HTF7700L tailored to each airframe. Its architecture, with a bypass ratio of 4.4 to 1 and an overall pressure ratio of 28.2, could be extended to 8,000 to 10,000 pounds of thrust. By October 2016 about 1,400 engines in service had logged 2.6 million hours with a 99.9 percent dispatch reliability rate.
