A gas turbine is a type of internal combustion engine that converts the chemical energy of fuel and air into mechanical energy through a series of physical and chemical processes. Gas turbines are widely used in a variety of applications, including power generation, aviation, marine propulsion, and industrial processes.
For a gas turbine engine, the accelerated gas, or working fluid, is the jet exhaust. Most of the mass of the jet exhaust comes from the surrounding atmosphere.

These turbine stages can be used to drive a low-pressure compressor (fan), propeller, and shaft. The turbine section of a gas turbine engine is located aft, or downstream, of the combustion chamber. Specifically, it is directly behind the combustion chamber outlet. The turbine assembly consists of two basic elements: turbine inlet guide vanes
Compare ramjet. Gas-turbine engine - Development, Efficiency, Power: The earliest device for extracting rotary mechanical energy from a flowing gas stream was the windmill (see above). It was followed by the smokejack, first sketched by Leonardo da Vinci and subsequently described in detail by John Wilkins, an English clergyman, in 1648.
A gas turbine engine is a device that is designed to convert the thermal energy of a fuel into some form of useful power, such as mechanical (or shaft) power or a high-speed
Gas turbine. Figure 1. A jet engine gas turbine. The flow is from left to right, with labeling of parts in Figure 2. [1] A gas turbine is a type of turbine that uses pressurized gas to spin it in order to generate electricity or provide kinetic energy to an airplane or jet. The process to do so is called the Brayton cycle.
THE GAS TURBINE CYCLE The basic principle of the airplane turbine engine is identical to any and all engines that extract energy from chemical fuel. The basic 4 steps for any internal combustion engine are: 1. Intake of air (and possibly fuel).
Turbine engines come in a wide variety of shapes and sizes because of the many different aircraft missions. All gas turbine engines have some parts in common, however. On the slide we see pictures of four different aircraft equipped with gas turbine engines. Each aircraft has a unique mission and therefore a unique propulsion requirement.
The basic gas turbine engine is described by the idealized Brayton air cycle as shown in Figure 16-8. In this cycle, air enters the air compressor (also called the "gas producer") at Point 1 under normal atmospheric pressure and temperature, P1 and T1.

A gas turbine, gas turbine engine, or also known by its old name internal combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: • a rotating gas compressor
Gas Turbine Construction. The gas turbine components mainly include a compressor, shaft, combustion chamber, gearbox & Exhaust. The working of this turbine includes different processes like suction, compression, combustion, turbine & electricity generation. The gas turbine parts & their functions are explained below. Construction of a Gas Turbine.
Siemens'' SGT-200 Industrial Gas Turbine for Power Generation (ISO) 6.75MW (e) Power Generation Package is of light modular construction, 50Hz or 60Hz, and suitable for small power generation, especially in locations where power to weight ratio is important (offshore applications) and small footprint is required.

A gas turbine uses fuels such as vaporized fuel oil gas, low-Btu coal gas, process gas, and natural gas. But the world''s 90% of
A gas turbine is a mechanical device that harnesses the energy of pressurized gas, typically air, to generate power. It operates by compressing incoming air, mixing it with fuel, igniting the mixture, and then allowing the high-speed exhaust gases to drive a turbine. This technology finds extensive use in aircraft engines, power plants,
Gas turbine engines derive their power from burning fuel in a combustion chamber and using the fast flowing combustion gases to drive a turbine in much the same way as the high pressure steam drives

Brayton Cycle – Turbine Engine. In 1872, an American engineer, George Bailey Brayton advanced the study of heat engines by patenting a constant pressure internal combustion engine, initially using vaporized gas but later using liquid fuels such as kerosene. This heat engine is known as " Brayton''s Ready Motor".

Gas turbine engines typically operate at air–fuel ratios of 60 : 1 or more. Combustion, however, takes place as a swirl-stabilized diffusion flame. There are three basic types of combustor: can combustor, can annular combustor, and annular combustor. Can combustors are used in very small or very simple engines.
