can you give the main differences between turbo prop engine and a jet engine?

Question

links to websites would be useful...

I also need to know about h-q characteristics of pumps-any web sites you know??

Answer 1

Turboprops are pretty much hybrids of jet engines and prop engines. Here's links:

P.S.--Cool NASA site, I stuck in my "favorites"!

Answer 2

First not all turbine engines are jets- a jet engine is a type of turbine that propels a vehicle by spitting out the exhaust. The M1 uses a turboshaft which uses a turbine to turn a shaft which in turn turns the wheels and moves the tank. Helicopters use the same type of engine to spin the rotor.

Answer 3

turbo prop use the same principal as turbo jet, only that, for pure jet engine, the turbine works is used mainly to drive the compressor only, whereby, for turboprop, the turbine is used to drive both the compressor and propeller.

so turboprop is really like the normal propeller aircraft engine, where its displaced a huge amount of air to propel aircraft.but the difference between the normal propellers engine and turboprop is only how that propellers got its power.but jet engine on the other hand use a little bit different approach in propelling the aircraft.the high temperature gas that comes out from the turbine is let to expand in the nozzle.and this will cause the gas flows to accelerate.and as from everyday experience, the faster the fluids flows, the more you can feels the force it exerted to you.(see how many firemen it needs to holds the water hose).the same principal goes to jet engine!it accelerate low speed air to a very very high speed air, which in turn will gives a very big force (thrust) to the aircraft.

Answer 4

Turboprop (Turboshaft similar) Strictly not a jet at all — a gas turbine engine is used as powerplant to drive propeller shaft (or Rotor in the case of a Helicopter) High efficiency at lower subsonic airspeeds (300 knots plus), high shaft power to weight Limited top speed (aeroplanes), somewhat noisy, complex transmission

A jet engine is an engine that discharges a fast moving jet of fluid to generate thrust in accordance with Newton's third law of motion. This broad definition of jet engines includes turbojets, turbofans, rockets, ramjets, pulse jets and pump-jets, but in common usage, the term generally refers to a gas turbine Brayton cycle engine, an engine with a rotary compressor powered by a turbine, with the leftover power providing thrust. Jet engines are so familiar to the modern world that gas turbines are sometimes mistakenly referred to as a particular application of a jet engine, rather than the other way around. Most jet engines are internal combustion engines but non combusting forms exist also.

Answer 5

In the jet engine, the thrust is provided by the engine (Gas Turbine) exhaust acting against the atmosphere.
Turbo-prop engines are lower power gas turbines driving propellers which provide the required thrust.

Answer 6

A jet engine uses the stages of turbine blades to compress,
the gases are then ignited, & exhausted for propulsion.
A turbo-prop uses the turbine blades to drive a propeller.

Answer 7

Simply put:
With the turbo-prop the bypass fan is on the outside.
