The turbine was designed to power a horseless carriage. His invention had most of the elements present in the modern day gas turbines. 1791: A patent was given to John Barber, an Englishman, for the first true gas turbine.1678: Ferdinand Verbiest built a model carriage relying on a steam jet for power.1629: Jets of steam rotated an impulse turbine that then drove a working stamping mill by means of a bevel gear, developed by Giovanni Branca.1500: The Smoke jack was drawn by Leonardo da Vinci: Hot air from a fire rises through a single-stage axial turbine rotor mounted in the exhaust duct of the fireplace and turns the roasting spit by gear-chain connection.When the lamp is lit, the heated airflow rises and drives an impeller with horse-riding figures attached on it, whose shadows are then projected onto the outer screen of the lantern. 1000: The 'Trotting Horse Lamp' ( Chinese: 走马灯, zŏumădēng) was used by the Chinese at lantern fairs as early as the Northern Song dynasty.It most likely served no practical purpose, and was rather more of a curiosity nonetheless, it demonstrated an important principle of physics that all modern turbine engines rely on. 50: Earliest records of Hero's engine ( aeolipile).Sketch of John Barber's gas turbine, from his patent Gas turbines are used to power aircraft, trains, ships, electrical generators, pumps, gas compressors, and tanks. The fourth step of the Brayton cycle (cooling of the working fluid) is omitted, as gas turbines are open systems that do not reuse the same air. The purpose of the gas turbine determines the design so that the most desirable split of energy between the thrust and the shaft work is achieved. 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 turbine, producing a shaft work output in the process, used to drive the compressor the unused energy comes out in the exhaust gases that can be repurposed for external work, such as directly producing thrust in a turbojet engine, or rotating a second, independent turbine (known as a power turbine) that can be connected to a fan, propeller, or electrical generator. Greater thrust-to-weight ratio for flight is achieved with the addition of an afterburner.

An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission ( turboshaft), marine propeller or electrical generator (power turbine). An extra turbine is added to drive a propeller ( turboprop) or ducted fan ( turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. A propelling nozzle is added to produce thrust for flight. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. 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:Īdditional components have to be added to the gas generator to suit its application. Examples of gas turbine configurations: (1) turbojet, (2) turboprop, (3) turboshaft (shown as electric generator), (4) high-bypass turbofan, (5) low-bypass afterburning turbofanĪ gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine.
