Gas turbines have changed the world. From powering aircraft for fast travel halfway across the world to providing power that lights up the world, gas turbines are simply indispensable.
Gas turbines can be broadly categorized into engines that are used to provide locomotive power and engines that are used for power generation and mechanical drive.
There are four main types of gas turbines used in aviation.
Other than these four there are also aeroderivative gas turbines used in electrical power generation. There are also different Industrial gas turbines that assist in power generation and mechanical drives. Apart from these, Turboshaft engines that power pumps used in petroleum drilling which also works on a similar principle.
The basic gas turbine engine is simple in construction:
The compressor draws in air and compresses it to about 8 atmospheric pressures. This compressed air is fed into the combustion chamber.
Gas turbines also produce a high pitched, high decibel whine that can be damaging at close quarters.
