For Air Force Cadets Engine types and how they work

1. AVP 3 Aircraft
Engines

2. 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

3. Piston engines Radial Engines
Radial engines early models the crankshaft was stationary and the cylinders
rotated
Later 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

4. 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)

5. Piston engines Horizontally opposed
Lycoming & Continental are the major manufacturers

6. Piston engines Horizontally opposed in aircraft

8. Gas Turbine engines
Commonly called Jet engines
• Ram Jet
• Pulse
• Radial Flow
• Axial Flow
• Turbo Fan
• Turboprop

9. Ram Jet Engine

10. Pulse Jet Engine

11. Pulse Jet Engines are dangerous and banned in Australia

12. Radial Flow Gas Turbine Engine
HdH Goblin engine in Vampire big brother the Ghost used in Comet

14. Axial Flow Gas Turbine Engine
How it Works
The engine featured was used in the Phantom
