  2. Brayton cycle - Wikipedia

    en.wikipedia.org/wiki/Brayton_cycle

    The Brayton cycle, also known as the Joule cycle, is a thermodynamic cycle that describes the operation of certain heat engines that have air or some other gas as their working fluid. It is characterized by isentropic compression and expansion, and isobaric heat addition and rejection, though practical engines have adiabatic rather than ...

  3. George Brayton - Wikipedia

    en.wikipedia.org/wiki/George_Brayton

    Brayton not only achieved success in making the constant pressure cycle work, but he also made and marketed a commercial product. Brayton cycle engines were some of the first engines to be used for motive power. In 1881 John Philip Holland used a Brayton engine to power the world's first successful self-propelled submarine, the Fenian Ram. [5]

  4. Inverted Brayton cycle - Wikipedia

    en.wikipedia.org/wiki/Inverted_Brayton_cycle

    The basic scheme of the IBC and temperature-enthalpy diagram are presented in figures 1 and 2. [4] For external heat sources or high temperature storage systems, the closed process design of the inverted Brayton Cycle is also possible. The overall efficiency can thus be significantly increased. [5]

  5. Airbreathing jet engine - Wikipedia

    en.wikipedia.org/wiki/Airbreathing_jet_engine

    The thermodynamics of a typical air-breathing jet engine are modeled approximately by a Brayton Cycle which is a thermodynamic cycle that describes the workings of the gas turbine engine, which is the basis of the airbreathing jet engine and others.

  8. Heat engine - Wikipedia

    en.wikipedia.org/wiki/Heat_engine

    A heat engine is a system that converts heat to usable energy, particularly mechanical energy, which can then be used to do mechanical work. [1] [2] While originally conceived in the context of mechanical energy, the concept of the heat engine has been applied to various other kinds of energy, particularly electrical, since at least the late 19th century.
