Parts - aircraft engine vortex blades

Different types of engines have different blade functions. Engines are roughly divided into pistons and jets. The piston is relatively early, and its blades are mainly used to generate force, that is, the blades rotate at high speed to produce thrust or lift (helicopter). Jet is relatively new, its blades do not produce thrust, such as turbofan engine, fan (blade) rotation when the air is sucked into the engine culvert, part of the air into the inner passage through the compressor into the combustion chamber and gas mixing for combustion, and most of the air into the outer culvert, and then high-speed ejection to produce thrust. Rectifier circuit, constant voltage rectifier circuit.
