5. Methods of thrust augmentation
Water Injection
After Burning
Air Bleed off

6. Water Injection
Done by increasing
weight of air flow
passing through engine.
Boosted 10% - 30% of
thrust
Mixture of De mineral
water and Alcohol

7. Place of the Water Injection
Front of the Compressor
Added to the Diffuser

9. AFTERBURNING
9

10. Use in Turbo Jets and Turbo fan engine types.
Periodically increase in thrust.
Much similar to Ramjet operation
Principle of Afterburning is increasing exit air velocity.
Cooperated with variable area exhaust nozzles.
