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).
Data from FAA General characteristics Type: Twin spool Turbofan Length: 105.8 in (269 cm) (flange to flange) / 130.44 in (331.3 cm) (fan spinner face to aft tail cone) Diameter: 50 in (130 cm) fan case Dry weight: 3,135.7 pounds (1,422.3 kg) (dry) Components Compressor: 24-blade, single-piece Single-stage fan, 2-stage LP and 8-stage HP compressor Turbine: 2 stage HP and 5 stage LP turbine LP ...
The program cost is estimated at $10 billion. Unlike traditional turbofan engines where a single shaft connects all components, forcing them to operate at the same speed, the PW1000G has a gearbox between the fan and the low-pressure core. This allows each section to operate at its optimal speed: the large front fan spins slower for maximum air ...
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 ...
In December 1980, Pratt & Whitney changed to a new naming system for its engines and the JT10D became the PW2037. The PW2000 is a dual-spool, axial air flow, annular combustion, high bypass turbofan with a dual-channel full authority digital engine control system. It was certified in 1984 as the first civilian FADEC-controlled aviation engine.
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 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 American Federal Aviation Administration certified the engine for commercial operation on January 4, 2006. [4] The engine was ground run for the first time on an A380 on August 14, 2006, in Toulouse. [5] On August 25, 2006, the same aircraft, A380-861 test aircraft (MSN 009), made the first flight of an Engine Alliance powered A380.
