Engines

ENGINES

There are 3 types of engine used in aircraft

• Piston – fuel petrol (higher octane than cars use)

• Gas turbine - fuel AVTUR (kerosene) • Rocket• None – gliders

Piston engines Radial Engines

Radial engines early models the crankshaft was stationary and the cylinders rotatedLater engines the cylinders were stationary and the crankshaft rotated R 2800 is known as the Prat & Witney Twin Row Wasp it has 18 cylinders (45.96 L) producing 2,800 hp (2,100 kW), Diameter: 52.8 in (1,342 mm) for Aircraft such as the DC6 and the Super Constellation

Piston engines V Engines most famous Rolls Royce Merlin

The engine that helped win WWII Length: 88.7 in (225 cm) producing 1,290 hp (962 kW)

Piston engines Horizontally opposed

Lycoming & Continental are the major manufacturers

Piston engines Horizontally opposed in aircraft

How they work

Gas Turbine engines

Commonly called Jet engines

• Ram Jet• Pulse• Radial Flow• Axial Flow• Turbo Fan• Turboprop

Ram Jet Engine

Pulse Jet Engine

Pulse Jet Engines are dangerous and banned in Australia

Radial Flow Gas Turbine Engine

HdH Goblin engine in Vampire big brother the Ghost used in Comet

Axial Flow Gas Turbine Engine

How it Works

The engine featured was used in the Phantom

Turbo Fan Engine
