Types of Turbine Engines

Turbine engines are favored for the many advantages that they have over reciprocating engines, such as an increased aviation performance, less vibration, and better reliability. There are many different types of turbine engines in the aviation market. They are classified based on their compressor and on whether or not they have axial flow, centrifugal flow or a combination of both. They can also be classified based on the flow that the air takes through the engine and how that power is produced. There are only four ways in which this flow can happen and you can find out more about that by learning about the four different types of turbine engines, which are the turbojet, turboprop, turbofan and turboshaft.

Turbojet

There are Gas Turbine Engine which First developed in England and Germany before the second World War, the turbojet engine is the least complex engine which has only four sections, These sections are the compressor, combustion chamber, turbine section and exhaust. The way this works is that by passing air at an increased rate of speed through to the combustion chamber containing the igniter and field inlet, the compressor can expand the air driving through the turbine and accelerate the exhaust gas enough so that it can provide thrust. The turbojet engine are primarily used in military aviation as the do tend to have a limit on endurance and range, and are known for being laggy when responding to throttle applications at slow compressor speeds,

Turboprop

The first turboprop engine was created by Hungarian designer Gyorgy Jendrassik between the years of 1939 through 1942. The turboprop design wasn’t actually implemented into an aviation vessel until 1945 when Rolls Royce converted a Derwint II into the RB50 Trent which flew on September 20, 1945 as the first turboprop jet engine. The turboprop engine is made up of a propeller that can drive through reduction gear and enable optimum performance from the propeller at speeds that are slower than the operating RPM. Because they can be more fuel efficient and can perform at slow ro fast airspeeds, turboprop engines are often used in small commuter aircraft as well as in agricultural applications. In addition to having more fuel efficiency, they tend to be more reliable than their counterpart engines and offset more cost.

Turbofan

The turbofan is unique in that it is the only type of turbine engine that combines the most favorable characteristics of both the turboprop and the turbojet engine. The turbofan can create an additional thrust by diverting a secondary airflow around the combustion chamber. One passes through the engine core while the second bypasses the core. One of the first ties that a turbofan engine was used in military or commercial aircraft was with the invention of the Gloster E28/39 when it flew on May 15, 1941

Turboshaft

Turboshaft engines are primarily used by helicopters. The very first turboshaft engine was built in 1949 by Turbomeca, a manufacturing firm in France. The way that the modern turboshaft works is by using most of the energy produced by expanding gasses and driving the shaft that is connected to the turbine through the single stage of reduction gearing rather than producing the jet thrust.
