Transcript

  • 1. Air Engines CUO Tonya Brown Apr 11 Flying Camp: Basic/Proficiency/Advanced Aviationnews.eu
  • 2. Aim
    • State the basic principles of operation and identify the basic components of:
      • A four stroke cycle internal combustion engine
      • Basic turbo jet engine
    • Demonstration of a type of thrust similar to that of engines found in jet aircraft
    Airforce.gov.au
  • 3. Four Stroke Piston Aircraft Engine
    • This has a cycle of four operations:
    • 1. Induction
    • 2. Compression
    • 3. Expansion (or Ignition)
    • 4. Exhaust
    Aussiex.org
  • 4. Induction
    • Inlet valve opens
    • Down stroke, to allow mixture of fuel and air into cylinder chamber
  • 5. Compression
    • Compression
    • Both valves remain closed
    • Rising piston compresses mixture
  • 6. Power/Ignition
    • Piston reaches end of compression
    • Inlet and Exhaust valves both closed
    • Mixture ignited by an electrical spark
    • The heat generated rapidly expands mixture
    • Forcing the piston down, thus turning the crankshaft
  • 7. Exhaust
    • At the beginning of final up stroke
    • Exhaust valve opened (Inlet valve remains closed)
    • Burnt gases released into atmosphere
    • Complete sweeping of cylinder by piston during upward travel cleans for next cycle
  • 8. The Jet Engine
    • Sequence of induction, compression, expansion and exhaust can be applied to turbo jet engine
    • All of these processes occur continuously in engine and delivery is uninterrupted (unlike a piston engine)
    Airforce.gov.au
  • 9.
    • Turbojet engine has no reciprocating parts
    • Therefore mechanically smoother and parts are less stressed than a piston engine
    • Figure shows general make-up of basic gas turbine engine
  • 10.
    • Incoming air is squeezed through the front fan (compressor) into the compression chamber
    • Add the fuel and ignited
    • Gases expand and flow out the rear of the engine
  • 11.
    • To maintain the movement of the compressor another fan (rear turbine) is located at the rear. Connected to the compressor by a shaft
    • Fan turned by hot gases passing through at very high velocity
    • After passing through turbine, the heated gases, still expanding, leave from exhaust nozzle as a jet
  • 12. Afterburning (Reheat)
    • Used for obtaining additional power
    • Feeding fuel into hot gases at back of engine
    • Heats the gases even more
    • Fuel ignited as soon as it comes in contact w/ hot gases
    • Increased expansion of air which was originally drawn from front gives aircraft extra thrust
    Airshow-reviews.com
  • 13. Use of Afterburning
    • Uses very large amount of fuel
    • Usually used to:
      • Shorten take-off
      • Increase rate of climb
      • Give extra speed for a short period of time

  • 14. Like this...
    • Newlunches.com
  • 15. No, obviously like this... Pixdaus.com
  • 16. Model Air Engine
    • Imagine that...
      • Straw = Fuselage
      • Balloon = Aircraft Engine
    • Air propelled to create forward motion
