4 TYPES OF GAS TURBINE ENGINE COMPONENTS, WORK PRINCIPLE

Gas-powered turbine engines have come a long way since 1903. That was the first year a gas turbine produced enough power to keep itself running.

The design was accomplished by Norwegian inventor Aegidius Elling, and it produced 11 horsepower, which was a massive feat at the time.

Gas turbine engines are mostly used in aircraft. There are four kinds of gas turbine engines. They are divided by the way they generate power.

This engine makes power by thrusting the compressed air into the atmosphere. 

These kinds of engines are usually used in supersonic jets. Because it needs thrusting power to push the vehicle.

Turbojet engines were the first type of gas turbine engine invented. 

And even though they look completely different from the reciprocating engine in your car or plane, they operate using the same theory:

  • ๐™˜๐™ค๐™ข๐™ฅ๐™ง๐™š๐™จ๐™จ๐™ž๐™ค๐™ฃ
  • ๐™ฅ๐™ค๐™ฌ๐™š๐™ง
  • ๐™š๐™ญ๐™๐™–๐™ช๐™จ๐™ฉ

The turbojet engine consists of four sectionsโ€”compressor, combustion chamber, turbine section, and exhaust

The compressor section passes inlet air at a high rate of speed to the combustion chamber. 

The combustion chamber contains the fuel inlet and igniter for combustion. The expanding air drives a turbine, which is connected by a shaft to the compressor, sustaining engine operation. 

The accelerated exhaust gases from the engine provide thrust. 

This is a basic application of compressing air, igniting the fuel-air mixture, producing power to self-sustain the engine operation, and exhaust for propulsion.

In this engine, the shaft itself rotates the propeller, which thrusts the air to the backside. 

Nowadays, these types of engines are not very popular. These engines are used in small personal types of aircraft. 

The turboprop is a turbojet engine connected to a propeller through a gearing system.

The typical turboprop engine can be broken down into assemblies as follows:

In this engine, the shaft itself rotates another fan that makes thrusts on the air. This is a very advanced engine. 

because the very short type of engine makes so much thrusting power.ย These kinds of engines are used in passenger aircraft.

Turbofans combine the best of both worlds between turbojets and turboprops. 

And, you’ll probably see these engines when you head out to the airport for your next airline flight.

Turbofans work by attaching a ducted fan to the front of a turbojet engine. 

The fan creates additional thrust, helps cool the engine, and lowers the noise output of the engine.

Steps:

  1. Inlet air is divided into two separate streams. One stream flows around the engine (bypass air), while the other passes through the engine core.
  2. Bypass air passes around the engine and is accelerated by a duct fan, producing additional thrust.
  3. Air flows through the turbojet engine, continuing the production of thrust.

Turboshaft engines are primarily used on helicopters. 

The biggest difference between turboshafts and turbojets is that turboshaft engines use the majority of their power to turn a turbine, rather than produce thrust out the back of the engine.

Turboshafts are essentially turbojet engines with the large shaft connected to the back of them. 

And since most of these engines are used on helicopters, that shaft is connected to the rotor blade transmission.

Steps:

  1. The engine operates like a turbojet, for the most part.
  2. Power shaft attached to the turbine powers the transmission.
  3. Transmission transfers rotation from the shaft to the rotor blade.
  4. The helicopter, through mostly unknown and magical means, can fly through the sky.
