Avg score: 30% Most missed: “Extra fuel is injected to afterburners to _________ the thrust.”
Gas Turbines – Anatomy and Applications topics include: Usage of fuels, bearing systems, cryogenics and hot gas path in gas turbines, usage of gas turbines in jet engines and hybrid vehicles, turbine, inlet and compressor casing and exhaust frames and micro gas turbines. Gas turbines are internal combustion engines that use liquid or gaseous fuels to produce mechanical power. They have three main sections: the compressor, combustor, and turbine.  Gas turbines have many applications, including: Power generation: Gas turbines are a clean, reliable, and efficient way to produce electricity....
