YQM-98 Compass Cope R. The ATF3 was first flown in the Teledyne Ryan YQM-98 Compass Cope R high altitude UAV, as the YF104-GA-100. The engine proved to have a very low infrared signature, as the hot turbine was not externally visible and the core exhaust mixed with the bypass air before exiting the engine.
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.
For the CX-X program GE demonstrated a half-scale engine, the GE1/6, with 15,830 lb thrust and an sfc of 0.336. [8] This was developed into the TF39 with a 97 in diameter fan. By modern standards the Low Pressure Compressor on the TF-39 is fairly unique as a single T-stage is mounted upstream of the fan rotor, rather than behind it.
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 ...
A modest fan pressure ratio, consistent with the high bypass ratio, meant a low fan tip speed could be employed. A low hot jet velocity was another major design feature. In reverse thrust, intake air entered the bypass duct, via a gap in the cold nozzle outer wall, and went through the fan, to be expelled through the intake. A small proportion ...
XF9-1 on a test run. The XF9-1 is a twin-spool axial-flow afterburning turbofan with a dual redundant FADEC, consisting of a 3-stage fan, a 6-stage high-pressure compressor, an annular type combustor, a single-stage high-pressure turbine, a single-stage low-pressure turbine, an afterburner, and a convergent-divergent nozzle.
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 ...
LF511D: An 11,000 lbf thrust (49 kN) turbofan with a 43 in diameter (1.09 m) wide-chord fan, a three-stage power turbine, and a three-stage low-pressure booster compressor [7] LF512 / LF514: Additional turbofan engines of 12,000–14,000 lbf (53–62 kN) thrust, possibly for Avro 's proposed 120-seat RJX twin airliner or for a stretched version ...
