Brayton cycle - Wikipedia
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 ...
Brayton Cycle: Definition, PV and TS Diagrams, and Efficiency
2023年12月12日 · The Brayton cycle is a thermodynamic cycle that describes the workings of a constant-pressure gas engine, such as modern gas turbine engines and airbreathing jet engines. It extracts energy from compressed air and fuel to generate valuable work.
Brayton Cycle – Definition, Meaning, Efficiency, Ts, Pv Diagram ...
Brayton cycle is the most common cycle known and describes the working of the constant pressure heat engines. The ideal Brayton cycle consists of two isentropic processes and two isobaric processes alternatively.
¯ The Brayton Cycle: The air- standard Brayton cycle is the ideal cycle for gas turbines. All 4 processes are internally reversible: (1) → (2): Isentropic Compression (2) → (3): Constant Pressure Heat Addition (3) → (4): Isentropic Expansion (4) → (1): Constant Pressure Heat Rejection. Air-standard gas turbine cycle [2]
Brayton Cycle – Types and Working Principle - Science Info
2022年12月14日 · A Brayton cycle is a thermodynamic cycle that explains how a heat engine with constant pressure works. A heat engine uses a Brayton cycle to extract energy from the moving fuel and air to create useful work, which is then used to propel a vehicle.
Brayton Cycle – Gas Turbine Engine - Nuclear Power for Everybody
In general, the Brayton cycle describes the workings of a constant-pressure heat engine. The Brayton cycle is one of the most common thermodynamic cycles found in gas turbine power plants or airplanes. The thermal efficiency in terms of the compressor pressure ratio (PR = p 2 /p 1), which is the parameter commonly used:

The Brayton cycle (or Joule cycle) represents the operation of a gas turbine engine. The cycle consists of four processes, as shown in Figure 3.13 alongside a sketch of an engine: d - a Cool the air at constant pressure back to its initial condition. The components of a Brayton cycle device for jet propulsion are shown in Figure 3.14.

Theory of Brayton Cycle – Brayton Engine - Nuclear Power for …
In general, the Brayton cycle describes the workings of a constant-pressure heat engine. It is one of the most common thermodynamic cycles found in gas turbine power plants or airplanes. In contrast to the Carnot cycle, the Brayton cycle does not execute isothermal processes because these must be performed very slowly.

The Brayton cycle is a constant-pressure cycle named after George Brayton (1830–1892), the American engineer who developed it. It is also sometimes known as the Joule cycle. It was originally proposed by Barber in 1791. The Ericsson cycle is also similar but uses external heat and incorporates the use of a regenerator.
