Turboprop Aircraft Charter Services!
The propeller is coupled to the turbine through a reduction gear that converts the high RPM, low torque output to low RPM, high torque.

In its simplest form a turboprop consists of an intake, compressor, combustor, turbine, and a propelling nozzle.
Air is drawn into the intake and compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts.
The hot combustion gases expand through the turbine. Some of the power generated by the turbine is used to drive the compressor.
The rest is transmitted through the reduction occuring in the propelling nozzle, where the gason gearing to the propeller.
Turboprops are most efficient at flight speeds below 725 km/h (450 mph; 390 knots) because the jet velocity of the propeller (and exhaust) is relatively low.

Due to the high price of turboprop engines, they are mostly used where high-performance short-takeoff and landing (STOL) capability and efficiency at modest flight speeds are required.
The most common application of turboprop engines in civilian aviation is in small commuter aircraft, where their greater power and reliability over reciprocating engines offsets their higher initial cost and fuel consumption.
Turboprop airliners now operate at near the same speed as small turbofan-powered aircraft but burn two-thirds of the fuel per passenger.
However, compared to a turbojet a propeller aircraft has a much lower ceiling.
Turboprop-powered aircraft have become popular for bush airplanes such as the Cessna Caravan and Quest Kodiak as jet fuel is easier to obtain in remote areas than is aviation-grade gasoline.
Both piston engine aircraft and small turboprop aircraft are right at home accessing smaller airports with shorter runways, making them the ideal way to reach many desirable final destinations, where larger aircraft simply cannot land.
Got a short range business trip to make and don't want to put up with the hassles and restrictions of commercial airliners?
Turboprops offer a lower priced alternative to jets for shorter charter flights.
While smaller than their larger jet brethren, turboprop aircraft have fully pressurized cabins, ensuring the maximum in comfort and safety.
One of the most attractive aspects of turboprops is their ability to operate into more airports and specifically those in smaller towns.

The Turboprops tend to be larger aircraft with greater passenger capacity - and more fuel on-board – and are more likely to be found flying distances of up to 1,300 miles.
Aircraft turbine engines generally fall into four common categories: turbojets, turbofans, turboprops and turboshafts.
However, in the case of a turboprop aircraft, the turbine drives a rotating shaft, which in turn drives a reduction gear, which ultimately drives a propeller.
Most of the power generated in a turboprop aircraft is used to drive the propeller and any remaining jet exhaust actually plays virtually no role in propulsion of the plane!
The Turboshaft engine is similar to the turbopropTurboshaft in that energy produced within the engine is used to drive a shaft rather than to produce jet stream thrust.

Turboprop aircraft are generally most efficient at altitudes of 20,000 to 30,000 feet and at average speeds of 250 to 300 mph
The turboprop aircraft cabins are typically pressurized these planes also commonly fly at higher altitudes.
