Turboprop in the context of "Open cycle gas turbine"

A motor fuel is a fuel that is used to provide power to the engine (motor) of vehicles — typically a heat engine that produces thermal energy via oxidative combustion of liquid or gaseous fuel and then converts the heat into mechanical energy through reciprocating pistons or gas turbines.

Currently, the majority of motor vehicles, powerboats and light aircraft worldwide are propelled by internal combustion engines powered by petroleum-based hydrocarbon fossil fuels such as gasoline, diesel or autogas, while larger ships and aircraft use marine diesel oil and kerosene to power gas/steam turbine, turboprop and jet engines. Other fuel types include ethanol, biodiesel, biogasoline, propane, compressed natural gas (CNG) and hydrogen (either using fuel cells or hydrogen combustion). There are also cars that use a hybrid drivetrain of different power sources. The use of synthetic alternative fuels (especially renewable biofuels) is increasing, especially in Europe, as well as increasing mass adoption of battery electric vehicles (which are powered by battery-stored electricity instead of fuels).

The Fokker 50 is a turboprop-powered airliner manufactured and supported by Dutch aircraft manufacturer Fokker. It was designed as an improved version of the successful Fokker F27 Friendship. The Fokker 60 is a stretched freighter version of the Fokker 50.

The Fokker 50 was developed during the early 1980s following a decline in the sales of the company's earlier F27 Friendship. It was decided that the new airliner would be a derivative of its predecessor, sharing much of its airframe and design features, while incorporating new advances and several improvements, such as the adoption of Pratt & Whitney Canada PW127B turboprop engines, in order to produce a successor that had a 30 percent reduction in fuel consumption over the F27.

The Partenavia P.68, now Vulcanair P68, is a light aircraft designed by Luigi Pascale and initially built by Italian company Partenavia.It made its first flight on 25 May 1970, its type certification was granted on 17 November 1971 and was transferred to Vulcanair in 1998.The original six-seat high-wing monoplane is powered by twin piston engines and is used for light transport and training. The P.68 Observer is an observation aircraft variant, and it was developed in a stretched, 10/11-seat twin turboprop derivative.

The EADS HC-144 Ocean Sentry is a medium-range, twin-engined turboprop aircraft used by the United States Coast Guard in the search-and-rescue and maritime patrol missions. Based on the CASA CN-235, it was procured as a "Medium Range Surveillance Aircraft." The HC-144 is supplied by Airbus Group, Inc, formerly EADS North America, and is built in Spain by CASA.

Mustique Airport (IATA: MQS, ICAO: TVSM) is a private airfield owned by the Mustique Company for public use and is located on Mustique island, part of Saint Vincent and the Grenadines in the Caribbean Sea. It is used by civil aviation and national airlines using turboprop planes.

The traffic has a large seasonal variation with many more passengers in the winter.

A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air.

The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis.

A gas turbine engine, or, informally, a gas turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow:

• a rotating gas compressor
• a combustor
• a compressor-driving turbine.

Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater thrust-to-weight ratio for flight is achieved with the addition of an afterburner.
