Type Aircraft Engines .

Aircraft Engine Types: Turboprop , Turbojet , Turbofans , turboshaft , ramjet .
The aircraft can fly because there is the thrust of the prime mover ( engine) which causes the aircraft has speed , and speed is what is received aerofoil shaped wing aircraft so the aircraft can be lifted / fly . The selection was based on the size of the engine size aircraft . The types of engine ( Engine ) aircraft are as follows :

1 . Turboprop Engine .

In the early development of the engine , generally commercial aircraft using turbo propeller propulsion systems or commonly called a turboprop . Type turbo prop had not much different system with turbo jets , but the energy (thrust ) generated by the propeller rotation by 85 % , which is driven by a propeller rotation turbine expansion that receives energy from the burning , the remaining 15 % to the exhaust jet thrust ( hot gas )
Turboprop engines are more efficient than the turbojet , designed to fly at speeds below 800 km / h ( 500 mph ) . Examples of popular turboprop engines include Rolls-Royce Dart engines used on aircraft British Aerospace , Fokker 27, etc.

2 . Turbojet engine.

The development of aircraft propulsion engine ( Engine ) is progressing very rapidly with the development of type turbojet engine , in which the propeller that serves to suck in air and produce a thrust force is replaced by a high-pressure compressor casing is closed , the engine together with the combustion chamber and turbine engines. Of the image under visible parts of a turbo-jet engine , which consists of a water inlet ( air duct ) , the compressor rotor and stator fins , fuel lines ( fuel inlet ) , combustion chamber ( chamber combustors ) , turbine and exhaust gas duct ( exhaust ) . Power thrust ( Thrust ) 100 % produced by the exhaust of jet thrust .
Turbojet engine is the simplest jet engine , typically used for high-speed aircraft . Examples of this machine is the Rolls-Royce engines used Olypus 593 for Concorde aircraft . Another type is the Olympus Marine engine that has the power of 28,000 hp ( horse power , equivalent to 21 MW ) is used to drive a modern warship with a deadweight of 20,000 tonnes with a high-speed operation .

3 . Turbofan Engine .

Turbo Fan is the most modern type of engine that combines technologies currently enjoys Turbo Prop and Turbo Jet . This machine is actually a by-pass engine in which a portion of the compressed air supplied to the combustion chamber and , while remaining a low density distributed around the outside of the combustion chamber ( by-pass ) . The air at the same time serves to cool the engine . Power thrust ( Thrust ) generated by the biggest FAN ( front baling-baling/blade measuring length ) , generates thrust by 80 % ( secondary airflow) , and the remaining 20 % to the exhaust jet thrust ( hot gas ) . At first glance it is similar to the turbo fan engine turbo prop , but the propeller in front of the turbo fan has a chamber cover ( casing / Fan case ) .
Engine / engine that uses this type of example is RB211 engines used on the Boeing B 747 GE CF6 - 80C2 and used on the DC 10 and the P & W JT 9D SERIES . Other machines that use this type of turbofan engines are Rolls-Royce Tay on Fokker F - 100 aircraft ( dubbed the engine fanjet ) , Adour Mk871 engines used on aircraft type Hawk Mk 100/200 Jaguar fighter aircraft and Mitsubishi F - 1 is used AU Japan .
Then the high by-pass engine turbofan is applied also to the CFM56 - 5C2 engine used by AIRBUS A340 aircraft and CFM56 - 3 engines used on the Boeing B - 737 series 300 , 400 and 500 which is a joint product between GE with Snecma of France .
In military aircraft , turbofan engines are applied , among others, the TF39 - 1C engines used on the giant transport aircraft C - 5GALAXI , then GE F110 used on the F - 16 .

4 . Ramjet Engine .

Ramjet is a type of engine ( engine ) where if the fuel and air mixture is sprinkled fire an explosion will occur , and when the explosion occurred continuously it will produce a thrust ( Thrust ) . Ramjet engine is divided into four sections , namely : inlet ( nozzle divergent ) section for incoming air stream , the mixture space is a space between the mixture of air and fuel are mixed so perfectly , combustor is equipped with a combustion chamber membrane , which serves to prevent back pressure , outlet ( convergent nozzle ) that serves to focus the thrust flow , retain heat and increase the temperature of the combustor .
Ram jet technology is generally developed in rocket / space shuttle . Drone 's X - 43A scramjet engine harness that in the future will also be used on the space shuttle . The privileges of the X - 434 is the use of a scramjet engine ( supersonic combustible ramjet ) . Scramjet using a new technology that burns hydrogen with oxygen taken from the air . Oxygen is inhaled and emitted again at breakneck speed .

5 . Turboshaft engines.

Turboshaft engine is actually a turboprop engine without a propeller . The power turbine is connected directly to the gearbox reduction or to a shaft ( axis ) so that the energy is measured in shaft
horsepower ( shp ) or kilowatts ( kW ) .
This type of machine is generally used to move the helicopter , the main rotor and the rotor moves the tail ( tail rotor ) but it is also used in industrial and maritime sectors including power generation , oil and gas pumping stations , hovercraft , and boats .
Examples of this machine is the GEM / 1004 RR -powered 900 shp applied to the helicopter type Lynx and Gnome engine 1,660 shp ( 1,238 kW ) on the Sea King helicopter . While other industry versions is 25-30 MW power plant engine Rolls-Royce RB 211 with shp 35000-40000 .
