The turbine is then able to drive both the compressor at the front of the engine and also some useful load. In airplanes, it produces thrust. The first jet engine was a turbojet. This is a simple turbine engine that produces all of its thrust from the exhaust from the turbine section.

However, because all of the air is passing through the whole turbine, all of it must burn fuel. This means it is inefficient, and the solution is the turbofan. In a turbofan, the turbine primarily drives a fan at the front of the engine.

Most engines drive the fan directly from the turbine. There are usually at least two separate shafts to allow the fan to spin slower than the inner core of the engine.

The fan is surrounded by a cowl which guides the air to and from the fan. Part of the air enters the turbine section of the engine, and the rest is bypassed around the engine.

What is the difference between turbojet,turboprop, and turbofan engines?

In high-bypass engines, most of the air only goes through the fan and bypasses the rest of the engine and providing most of the thrust. In a turboprop, the turbine primarily drives a propeller at the front of the engine.

There is no cowl around the prop. Some air enters the turbine, the rest does not. The propeller is geared to allow it to spin slower than the turbine. Although this diagram shows only a single shaft, many turboprops have two, with a high pressure shaft driving the compressor and a low pressure shaft driving the propeller.

Some engines such as the popular PT6 also reverse the flow direction multiple times. Turboprops are more efficient at lower speeds since the prop can move much more air with a smaller turbine than the fan on a turbofan engine.Mar 22,  · The basic difference between a Turbofan and a Turbojet Engine.

Turbojet engines were the first jet engines ever made. Turbofans came out later as a more efficient and noise-proof version of the.

Turbofan vs Turboprop To overcome disadvantages in the performance of the turbojet engines at subsonic speeds, such as efficiency and noise, advanced variants were built based on the turbojet engines. Turbofan Engine Combines thrust from exhaust gases[%] with thrust from a duct-enclosed fan that accelerates bypass air around the generator [%].

The fan may be driven by a free or power turbine. The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft caninariojana.com word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to .

The turbofan or fanjet is a type of airbreathing jet engine that finds wide use in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which takes mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to.

A turbofan engine in sense can be thought of as combination of a Propellor and a Jet engine where, an exposed propeller blades are replaced by a fan blades.

Let me elaborate further An Aircraft has four forces acting on it- thrust, lift, drag and weight.
