  2. Specific weight - Wikipedia

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  3. Gas turbine - Wikipedia

    en.wikipedia.org/wiki/Gas_turbine

    The basic operation of the gas turbine is a Brayton cycle with air as the working fluid: atmospheric air flows through the compressor that brings it to higher pressure; energy is then added by spraying fuel into the air and igniting it so that the combustion generates a high-temperature flow; this high-temperature pressurized gas enters a ...

  4. Pratt & Whitney GG4 - Wikipedia

    en.wikipedia.org/wiki/Pratt_&_Whitney_GG4

    The Pratt & Whitney GG4 and FT4 are related aero-derivative gas turbine engines developed from the Pratt & Whitney J75/JT4 turbojet line. [1] [2] See also

  5. JP-10 (fuel) - Wikipedia

    en.wikipedia.org/wiki/JP-10_(fuel)

    Developed to be a gas turbine fuel for cruise missiles, [1] it contains mainly exo-tetrahydrodicyclopentadiene (exo-THDCPD) with some endo-isomer impurity. [2] About 100 ppm of alkylphenol-based antioxidant is added to prevent gumming. Optionally, 0.10–0.15% of fuel system icing inhibitor may be added. [3]

  6. Standard sea-level conditions - Wikipedia

    en.wikipedia.org/wiki/Standard_sea-level_conditions

    Standard sea-level conditions (SSL), [1] also known as sea-level standard (SLS), defines a set of atmospheric conditions for physical calculations.The term "standard sea level" is used to indicate that values of properties are to be taken to be the same as those standard at sea level, and is done to define values for use in general calculations.

  7. General Electric GE38 - Wikipedia

    en.wikipedia.org/wiki/General_Electric_GE38

    The GE27 also had a compressor air flow of 27–28 pounds per second (12–13 kg/s) and a turbine temperature of 2,400–2,500 °F (1,320–1,370 °C; 2,860–2,960 °R; 1,590–1,640 K). [2] The GE27 first ran in late 1984, but it unexpectedly lost the V-22 engine competition to the Allison 501-M80C , which was not a participant in the MTDE ...

  8. Turbine inlet air cooling - Wikipedia

    en.wikipedia.org/wiki/Turbine_Inlet_Air_Cooling

    An inlet air cooling system installed in a desert-dry area to increase turbine power output. Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine. The direct consequence of cooling the turbine inlet air is power output augmentation.

  9. Klimov TV2-117 - Wikipedia

    en.wikipedia.org/wiki/Klimov_TV2-117

    The Klimov TV2-117 (initially Isotov TV2-117) is a Soviet gas-turbine turboshaft engine intended for helicopter use. Designed in the early 1960s by the Isotov Design Bureau the engine became the first purpose built gas turbine engine for helicopter use by the Soviet Union with previous helicopter turbines being adapted aeroplane powerplants.
