The F136 is a twin-spool axial-flow low-bypass turbofan. It has a 3-stage low-aspect ratio fan driven by a 3-stage low-pressure turbine, and a 5-stage compressor driven by a single-stage turbine; both the fan and compressor stages are one-piece blisks. The STOVL variant's shaft-driven LiftFan is connected to the low-pressure spool and engaged ...
An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...
A cross-flow fan is a centrifugal fan in which the air flows straight through the fan instead of at a right angle. The rotor of a cross-flow fan is covered to create a pressure differential. A cross-flow fan has two walls outside the impeller and a thick vortex wall inside. The radial gap decreases in the direction of the impeller rotation.
After more than 50 years as a south side restaurant, Jim’s Coney Island goes through a transition to a new owner in August. Since 1971, the Frangos family has served chili dishes, onion rings ...
Starting in the late 1940s the carpet cleaning floor nozzle with the brush roller could be removed, and the 1948 owners manual for the Model 508 called it the "Triple-Cushion Vibrator", [12] which was powered by a removable rubber belt that was in contact with a metal shaft extending from the vacuum turbine blades, powered by the electric motor ...
The General Electric J79 is an axial-flow turbojet engine built for use in a variety of fighter and bomber aircraft and a supersonic cruise missile.The J79 was produced by General Electric Aircraft Engines in the United States, and under license by several other companies worldwide.
General Electric (GE) began developing the GE37, which would become basis of the XF120 and YF120, for the Joint Advanced Fighter Engine (JAFE) program in the early 1980s aimed at supplying the powerplant for the Air Force's Advanced Tactical Fighter (ATF) and the Navy's Advanced Carrier-Based Multirole Fighter (VFMX); JAFE was later renamed the ATF Engine (ATFE) following VFMX's cancellation.
the rear of the F135 engine (nozzle rotated down) that powers the Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift ...
