A turboshaft engine is a variant of a jet engine that has been optimised to produce shaft power to drive machinery instead of producing thrust. The power turbine extracts almost all of the energy from the exhaust stream and transmits it via the output shaft to the machinery it is intended to drive.
What is the difference between turbofan and turboprop?
The fundamental difference lies in how the remaining exhaust energy is used. Turboprops extract virtually all of the kinetic energy and a larger portion of the thermal energy via expansion turbines to drive the propeller, while turbofans utilize an expansion nozzle to create high speed exhaust (thrust).
What planes use Pratt Whitney engines?
P&W engines can be found on the A220, the A320 family, A330, 747-400s, 767, and Embraer E-jets. In recent years, the manufacturer has seen its narrowbody aircraft engines do well and has been focusing on those.

Does turboshaft produce thrust?
4) Turboshaft Engine 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.
What is a geared turbofan engine?
The geared turbofan is a more efficient type of turbofan aircraft engine. Gears allow the compressor-turbine assembly and the fan to spin at different angular velocities.
What are the parts in a turbo fan engine?
The first part of the turbofan is the fan. It’s also the part that you can see when you’re looking at the front of a jet. The fan, which almost always is made of titanium blades, sucks in tremendous quantities of air into the engine. The air moves through two parts of the engine.
How does a turbofan engine work?
All of the air that enters the engine passes through the engine. It moves a small volume of air at high velocities. * Turbofan engines produce thrust primarily by driving a large fan in front of the engine.
Is turbo engine good?
Turbos are not good for any engine. While they can increase horsepower and fuel economy they are not good for the engine. The crank and rods in an engine are designed with certain rpm and compression constraints. Exceeding factory performance decreases engine lifespan.
