The Boeing KC-135 Stratotankers were all originally powered by turbojet engines. With the demise of many airline 707s, the United States Air Force took the opportunity to buy the surplus airframes and use the engines to re-fit the KC-135As used by the Air National Guard and reserve squadrons with the civilian JT3D (designated TF33-PW-102). Over ...
The JT8D is an axial-flow front turbofan engine incorporating a two-spool design. There are two coaxially-mounted independent rotating assemblies: one rotating assembly for the low pressure compressor (LPC) which consists of the first six stages (i.e. six pairs of rotating and stator blades, including the first two stages which are for the bypass turbofan), driven by the second (downstream ...
The fuel system as explained above is one of the two systems required for starting the engine. The other is the actual ignition of the air/fuel mixture in the chamber. Usually, an auxiliary power unit is used to start the engines. It has a starter motor which has a high torque transmitted to the compressor unit. When the optimum speed is ...
It also included a modified bleed management and air-conditioning ducting system, modified fuel and hydraulic systems, and a powerplant control/airframe interface. It was first flown on 30 July 1986. Two PW1120 powerplants were installed in the same F-4E and it was flown for the first time on 24 April 1987.
The P-409 engine was also proposed for use in the EA-6B ADVCAP, [10] but that program was canceled after three prototypes were built and flown. The P-409 would have been available as a new engine or as an upgrade kit for P-408 engines, but was never ordered in significant quantities. [11] [12] PW1212 J52-P-409 re-designated PW1216
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.
The General Electric/Allison J35 was the United States Air Force's first axial-flow (straight-through airflow) compressor jet engine. Originally developed by General Electric (GE company designation TG-180 ) in parallel with the Whittle -based centrifugal-flow J33 , the J35 was a fairly simple turbojet , consisting of an eleven-stage axial-flow ...
The development program ran into many problems with this engine, including the original electronic control system, compressor/turbine mismatches, combustion instability and control issues at altitude leading to compressor stalling The produced -8, -8A and -8B engines were all derated from the original design specification on both thrust and ...
