How Gas Turbine Engines Work A gas turbine is an extension of the same concept. In a gas turbine, a pressurized gas spins the turbine. In all modern gas turbine engines, the engine produces its own pressurized gas, and it does this by burning something like propane, natural gas, kerosene or jet fuel.

reaction turbine Noun. 1. reaction turbine-a turbine with blades arranged to develop torque from gradual decrease of steam pressure from inlet to exhaust. turbine-rotary engine in which the kinetic energy of a moving fluid is converted into mechanical energy by causing a bladed rotor to rotate.. (Mechanical Engineering) a turbine in which the working fluid is accelerated by expansion in both the static nozzles and the rotor blades. Torque is produced by the momentum changes in the rotor and by reaction from fluid accelerating out of the rotor. Compare impulse turbine.

Animation: How a Wind Turbine Works A wind turbine works on a simple principle. This animation shows how energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most energy.

- Combustion turbines operate differently from coal-fired or nuclear plants. Rather than using steam to drive a turbine, combustion turbines harness the nature of air to expand when it is heated. 3. Turbine. The expanding air pushes the turbine generators much like steam does in a steam-electric station.

Steam turbine Because the turbine generates rotary motion, it is particularly suited to be used to drive an electrical generator – about 90% of all electricity generation in the United States (1996) is by use of steam turbines.he first device that may be classified as a reaction steam turbine was little more than a toy, the classic Aeolipile, described in the 1st century by Greek mathematician Hero of Alexandria in Roman Egypt. In 1551, Taqi al-Din in Ottoman Egypt described a steam turbine with the practical application of rotating a spit.

Ryan Alizadeh.ind turbines typically cut in at 7-9 miles per hour. Some wind turbines are designed for very low wind conditions and will start in winds of 2-4 miles per hour. These are only useful in the very lowest of winds.

News Converting Wind to Mechanical Energy. Wind is converted by the blades of wind turbines. The blades of the wind turbines are designed in two different ways, the drag type and lift type. • Drag type: this blade design uses the force of the wind to push the blades around. These blades have a higher torque than lift designs but with a slower rotating speed. The drag type blades were the first designs used to harness wind energy for activities such as grinding and sawing.

Steam turbines As its name suggests, a steam turbine is powered by the energy in hot, gaseous steam—and works like a cross between a wind turbine and a water turbine. Like a wind turbine, it has spinning blades that turn when steam blows past them; like a water turbine, the blades fit snugly inside a sealed outer container so the steam is constrained and forced past them at speed.

Wind turbine design As of 2015 the rotor diameters of onshore wind turbine blades are as large as 130 meters, while the diameter of offshore turbines reach 170 meters. In 2001, an estimated 50 million kilograms of fibreglass laminate were used in wind turbine blades. An important goal of larger blade systems is to control blade weight.n addition to aerodynamic design of the blades, design of a complete wind power system must also address design of the hub, controls, generator, supporting structure and foundation. Further design questions arise when integrating wind turbines into electrical power grids.

Steam turbines The blades are the most important part of a turbine: their design is crucial in capturing as much energy from the steam as possible and converting it into rotational energy by spinning the rotor round. All turbines have a set of rotating blades attached to the rotor and spin it around as steam hits them.
