What is the difference between propeller and turbine

The turboshaft engine uses jet blast directed over turbines to turn a series of gears connected to the shaft of the helicopter blades. In other words, the turboshaft is a turboprop with different gearing. Matthew A.

Prop Power The earliest airplanes all had propellers, as the technology to contain jet explosive power did not arrive until World War Two. The Arrival of Jet Engines Recognizing the limitation of propellers, airplane designers looked to the nascent technology of rockets as a solution for more speed.

More of Jet and Propeller Propulsion Another combination of jet and prop is the turboprop engine. This pressure difference pushes both air and water behind the blade. Propellers are made heavy use of both in aviation as well as in ships. Have you ever paid attention to the working behind the water pump that is used at home that sucks water from the main pipeline passing through the main road and brings it inside your home and then lifts it to the over head tank?

The working principle behind this pump is the impeller inside a casing that creates a sucking force that draws in liquid at a great force and diverts it to your overhead tank. An impeller is always inside a casing as its purpose is to draw the liquid inside as against a propeller that provides an outward thrust and is always open. An impeller, because of its rotation and especially designed blades, increases the pressure of the fluid and thus its flow. A centrifugal pump used to draw fluid is the best example of an impeller.

A propeller moves itself, and whatever it is attached to, through a medium such as water or air whereas an impeller moves the medium again, water or air while itself remains stationary. If you look out for the types of the pump blade u will find axial pump which acts exactly like a propeller i say if the fan or blade is used to move the body like ships and planes it is called propeller but if the body is stationary and moving another medium or object it is called impeller.

Therefore, turbines tend to have higher loads and require thicker profiles. Airplane propeller has blade angle almost perpendicular to the rotor axis. It normally ranged degree. More than 15 degree will produce more drag, compare to the trust. Wind propeller has blade angle almost parallel to the axis. Angle of Attack AoA of propeller and wind turbines are seen from different perspective.

AoA of a propeller is seen from the axis itself parallel to the blade. It is just how the bolt corrugation. Meanwhile the AoA of wind turbine blades is seen from the frontal site, parallel to the axis. This two kinds of bold. The single one is reflecting the AoA of propeller. The corrugation almost perpendicular to the bolt axis itself.

While the smaller bold in the second picture, showing longer pitch. The longer the pitch until almost parallel to bolt axis itself, the more suitable to the wind turbine blade. There is a BIG difference. The curve of the blades is reversed. On a propellor, the leading edge is close to the propellor disk, with the flatter surface towards the rear.

In a turbine, the leading edge points forward into the wind , with the flatter surface also forward. Sign up to join this community. The best answers are voted up and rise to the top.
