performance calculations for the GE-Snecma CFM56-5B1 aircraft engine

GE-Snecma CFM56-5B | An exposed jet engine at a trade show. The rear of the polished metal fan case is visible on the left. The outer casing of the compressor section, covered in fuel lines and electrical wires is to the right of the fan case. The right of the image shows the back of the engine, the exhaust area of the turbine section.
