AE 3007 on an Embraer ERJ 145. In 1988, Allison Engine Company (then owned by General Motors) and Rolls-Royce plc began joint studies of a 33 kN (7,400 lb f) RB580 to power the proposed Short Brothers FJX regional jet, combining the T406 core with a Rolls-Royce low-pressure spool.
The shroud-less fan has wide-chord, low aspect ratio hollow titanium fan blades that are linear-friction welded to the disks to form single-piece integrally-bladed rotors (IBRs), or blisks. The fan and compressor stators and thrust-vectoring nozzle use a burn-resistant titanium alloy called Alloy C, with the first row of vanes variable in order ...
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 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 F414 uses the core and full-authority digital engine control (FADEC) from the F412, and the low-pressure system from the YF120 engine developed for the Advanced Tactical Fighter competition. One of the major differences between the F404 and the F414 is the fan section. The F414 fan is larger than that of the F404, but smaller than the F412 ...
The engine has a wide-chord swept fan, two-stage low-pressure compressor and counter rotating high-pressure compressor based on a titanium impeller, for a 2,050 lbf (9.1 kN) takeoff thrust. [5] The HF120 engine's components interact with greater efficiency by incorporating 3D aerodynamic design, and its effusion-cooled combustor design emits ...
It would be built under licence by Bet-Shemesh Engines Limited in Israel. IAI installed one PW1120 in the starboard nacelle of an F-4E-32-MC of the IDF/AF (Number 334/66-0327) to explore the airframe/powerplant combination for an upgrade program of the F-4E, known as Kurnass 2000 ("Heavy Hammer") or Super Phantom and to act as an engine testbed ...
The General Electric CF700 (military designation TF37) is an aft-fan turbofan development of the CJ610 turbojet. The fan blades are an extension of the low-pressure turbine blades. The fan blades are an extension of the low-pressure turbine blades.
