  3. Group 4 compression - Wikipedia

    en.wikipedia.org/wiki/Group_4_compression

    Group 4 compression is available in many proprietary image file formats as well as standardized formats such as TIFF, CALS, CIT (Intergraph Raster Type 24) and the PDF document format. G4 offers a small improvement over G3-2D by removing the end-of-line (EOL) codes. G3 and G4 compression both treat an image as a series of horizontal black ...

  4. Axial compressor - Wikipedia

    en.wikipedia.org/wiki/Axial_compressor

    A typical stage in a commercial compressor will produce a pressure increase of between 15% and 60% (pressure ratios of 1.15–1.6) at design conditions with a polytropic efficiency in the region of 90–95%. To achieve different pressure ratios, axial compressors are designed with different numbers of stages and rotational speeds.

  5. Overall pressure ratio - Wikipedia

    en.wikipedia.org/wiki/Overall_pressure_ratio

    Engine pressure ratio (EPR) differs from OPR in that OPR compares the intake pressure to the pressure of the air as it exits the compressor, and is always greater than 1 (often very much so), whereas EPR compares the intake pressure to the pressure at the engine's tailpipe (i.e., after the air has been used for combustion and given up energy to ...

    An EL/M-2084 antenna of the Vietnamese Air Defence Force. It exhibited alongside a SPYDER-MR battery, which the EL/M-2084 acts like a fire-control radar for the respective SPYDER system. The ELM-2084 is an Israeli ground-based mobile 3D AESA multi-mission radar (MMR) family produced by ELTA, a subsidiary of Israel Aerospace Industries. [1]

  8. Bleed air - Wikipedia

    en.wikipedia.org/wiki/Bleed_air

    Bleed air in aerospace engineering is compressed air taken from the compressor stage of a gas turbine, upstream of its fuel-burning sections.Automatic air supply and cabin pressure controller (ASCPC) valves bleed air from low or high stage engine compressor sections; low stage air is used during high power setting operation, and high stage air is used during descent and other low power setting ...

    en.wikipedia.org/wiki/MultiAir

    In 2010, the 1.4 L MultiAir engine won the International Engine of the Year [8] as well as Popular Science's Best of What's New. [1] In the same year, the Fiat SGE engine (0.9 L turbocharged and 1.0 L naturally aspirated TwinAir units), also using MultiAir technology, was launched in the Fiat 500.
