On entering service as one of the 35 members of the NN Class, it was allocated road number 1314, being renumbered in 1924. In the early 1930s, it was one of three C35s painted Oxford blue to operate the Caves Express. Throughout its service life, it received the various modifications made to the class, and was rebuilt with new frames and cab in ...
The compressed air was then ducted into a combustion chamber where a liquid fuel was sprayed and burnt. The heated compressed air then exits through the tailpipe providing static thrust of 180 kgf (397 lbf). It is likely that about 1/3 of the total thrust was contributed by adding the combustion chamber aft of the compressor.
Compressor stages run at their maximum efficiency when spinning at a specific speed for any given input air pressure - in a perfect compressor each stage would run at a separate speed. The multi-spool design, first used on the Bristol Olympus turbojet, [ 1 ] is a compromise, the compressor being separated into "spools" designed to operate ...
Developed by GE Aircraft Engines during the late 1960s, the original engine comprises a single stage fan, driven by a 4-stage low pressure (LP) turbine, supercharging a 14-stage high pressure (HP) compressor, driven by a 2-stage HP turbine. An annular combustor is featured. The TF34-GE-400A is rated at 9,275 lbf (41.26 kN) static thrust.
In piston engines, static compression ratio is determined using the cylinder volume when the piston is at the top and bottom of its travel. The compression ratio is the ratio between the maximum and minimum volume during the compression stage of the power cycle in a piston or Wankel engine .
The BR715 is another twin-shaft turbofan; this engine was first run in April 1997 and entered service in mid-1999. This version powers the Boeing 717 . A new LP spool, comprising a 58 in (150 cm) diameter single-stage fan, with two-stage LP compressor driven by a three-stage LP turbine, is incorporated into the BR715.
The engine's name is a combination of the Roman numeral V, symbolizing the five original members of the International Aero Engines consortium, formed in 1983 to produce the engine, and 2500, which represents the 25,000-pound-force (110 kN) thrust produced by the original engine model, the V2500-A1.
Mockup with compressor and turbine cutaway. After the budget of NASA on aeronautics research was severely cut at the start of 2006, Pratt & Whitney committed to spend $100 million a year on the geared turbofan (GTF) development for the next generation of single-aisle airliners, focused on the 25,000–35,000 lbf (110–160 kN) thrust range.
