| "summary": "A turbofan jet engine is a type of gas turbine engine commonly used to power modern commercial and military aircraft. It works by pulling air into the engine using a large front fan, compressing it, and mixing it with fuel to ignite. The resulting high-pressure exhaust gases spin a turbine and shoot out the back to generate thrust, while some air bypasses the core to increase efficiency and reduce noise.", | |
