🫡🫡🫡✈ Aircraft Engine – Working, Types & Popular Models (CFM, LEAP, Trent) An aircraft engine is the powerplant of the aircraft. Its primary function is to generate thrust, which moves the aircraft forward and enables lift. In simple terms: Intake → Compression → Combustion → Exhaust Air enters → gets compressed → fuel ignites → high-speed exhaust gases produce thrust. This works on Newton’s Third Law of Motion. 🔎 Main Types of Aircraft Engines Aircraft engines are broadly classified into: 1️
