3. Aeolipile invented by Heron of Alexandria (first reaction engine) Jet Propulsion took off with the invention of the rocket by the Chinese in the 13 th Century Heinkel He 178 – first practical jet to fly on 27.08.1939

4. Newton’s Third Law: For every action (i.e. exhaust gases) there is an equal and opposite reaction (i.e. Thrust). 1.Front Fan sucks cold air into the engine 2.Secondary fan compresses the air, increasing pressure 8x 3.Liquid fuel is mixed with air and ignited. (1650 F) 4.Exhaust exit through turbine blades, which turns the compressor and fan. 5.Gases exit through exhaust nozzle. (1300 mph)

5. High-Bypass Turbofan Engine Low-Bypass Turbofan Engine

6. Commercial Jets powered by high-bypass ratio turbofan engines. Combat Aircraft powered by low-bypass ratio turbofans Gas turbine engines in helicopters, powerplants, M1- Abram Tank
