The engine has an overall pressure ratio of 35:1, which is extremely high for an engine with a centrifugal compressor. Other cycle parameters are a bypass ratio of 5.3 and airflow of 240 lb/s (108.9 kg/s).
The GE Passport is a high bypass ratio turbofan. The engine is a twin-spool, axial-flow turbofan with a high bypass ratio of 5.6:1 and an overall pressure ratio of 45:1. The front fan is attached to the three-stage low-pressure compressor; the 23:1 pressure ratio 10-stage high-pressure compressor includes five blisk stages for weight reduction.
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. [3] More than 3.5 million flight hours have been logged till October 2017, and the 2,000th engine should be delivered in 2018. [2] Honeywell maintenance program is $447 for two engines per ...
The Garrett TFE731 (now Honeywell TFE731) is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace.
The development of the PW800 stretches back to demonstration projects in 1999, soon after the development of the PW600 very light engine and the PW300 business jet engine. [1] After the Advanced Technology Fan Integrator demonstrator first ran on March 17, 2001, which became the PW1000G, Pratt & Whitney Canada was searching for a launch ...
The F124 engine is a low-bypass, two-spool engine (meaning that there are two rotating shafts, a high-pressure shaft and a low-pressure shaft). The fan/low-pressure compressor has three stages with titanium blades. The first stage has 30 blades, [19] and the overall pressure ratio for the three-stage fan is 2.5:1. Some of the air is bypassed ...
The Williams F107 (company designation WR19) is a small turbofan engine made by Williams International.The F107 was designed to propel cruise missiles.It has been used as the powerplant for the AGM-86 ALCM, and BGM-109 Tomahawk, as well as the experimental Kaman KSA-100 SAVER and Williams X-Jet flying platform.
The engine, with a fan diameter of 134 in (340 cm), is installed in a 174 in (440 cm) diameter nacelle, with 1.5 ft (0.46 m) of ground clearance. [17] The engine and nacelle weighed 40,000 lb (18 t) with its new pylon and wing strengthening, compared to 17,000 lb (7.7 t) for the CF6-80C2s and its pylon.
