Q2. How do gas turbine engines work
Ans. 
Gas turbine engines work by compressing air, mixing it with fuel, igniting the mixture, and using the hot exhaust gases to spin a turbine.
• Air is drawn into the engine and compressed by a compressor

• Fuel is injected and mixed with the compressed air

• The mixture is ignited, causing a rapid expansion of gases

• The hot exhaust gases are used to spin a turbine, which drives the compressor and generates thrust
