✈️Jet engines work on the principle of Newton's third law of motion, using reaction force to propel the aircraft forward.
🔥A combustion chamber combines fuel and cold air to produce high-speed, hot air.
🔄Compressor stages compress incoming air, making it suitable for combustion.
⚙️Turbines rotate to power the compressor and extract energy from the hot air.
🚀The narrowing duct and turbofan engine design improve jet velocity and fuel efficiency.
How do jet engines work?
—Jet engines work by harnessing the principle of reaction force, producing high-speed jet propulsion to propel an aircraft forward.
What is the combustion chamber's role in a jet engine?
—The combustion chamber combines fuel and cold air to generate high-speed, hot air for propulsion.
Why do jet engines need compressors?
—Compressors compress incoming air, increasing its temperature and pressure, making it suitable for combustion.
What do turbines do in a jet engine?
—Turbines power the compressor, extracting energy from the hot air as it leaves the combustion chamber.
What is a turbofan engine?
—A turbofan engine is a type of jet engine that bypasses a significant amount of air, improving fuel efficiency and reducing noise.
