2. Compressor characteristic - Wikipedia

   en.wikipedia.org/wiki/Compressor_characteristic

   Compressor characteristic is a mathematical curve that shows the behaviour of a fluid going through a dynamic compressor. It shows changes in fluid pressure , temperature , entropy , flow rate etc.) with the compressor operating at different speeds.

3. Rolls-Royce Trent 500 - Wikipedia

   en.wikipedia.org/wiki/Rolls-Royce_Trent_500

   [3] The Trent 500 is essentially a scaled Trent 800, with a 2.47 m (97 in) fan with 26 unswept blades like the Trent 700. The IP and HP compressors and scaled-down by 20% from the Trent 892, while the turbines are scaled-down by 90% and are made of single crystal CMSX-4 alloy with thermal barrier coatings. Fuel burn is 1% lower because of 3D ...

4. Compressor map - Wikipedia

   en.wikipedia.org/wiki/Compressor_map

   The map may be produced by driving the compressor with an electric motor with the flow resistance selected artificially using a variable area throttle valve. The compressor may also be mapped if it is part of a gas generator with a valve at the turbine exit. Campbell [10] shows a General Electric J79 compressor mapped in this way.

5. Variable-speed air compressor - Wikipedia

   en.wikipedia.org/wiki/Variable-speed_air_compressor

   A professional air audit is the best way to identify if a VSD compressor is most appropriate for any given compressed air application. [2] These audits are available from various companies that specialize in the implementation of compressed air equipment, which can determine the most efficient controls for a compressed air system – including ...

6. Gas turbine engine compressors - Wikipedia

   en.wikipedia.org/wiki/Gas_turbine_engine_compressors

   Through the compressor, the flow area decreases and the blades get smaller and smaller from stage to stage and this compensates for the increase of air pressure and density, creating a constant axial velocity. In axial compressors, there may be up to 20 stages between the air inlet and compressor outlet.

7. Rotary-screw compressor - Wikipedia

   en.wikipedia.org/wiki/Rotary-screw_compressor

   As an example, a 250 HP compound compressor is a large piece of equipment that generally requires a special foundation, building accommodations and highly trained riggers to place the equipment. On the other hand, a 250 HP rotary-screw compressor can be placed on an ordinary shop floor using a standard forklift. Within industry, a 250 HP rotary ...
