Jet engine theory
A jet engine is a machine that converts energy-rich, liquid fuel into a powerful pushing force called thrust. The thrust from one or more engines pushes a plane forward, forcing air past its scientifically shaped wings to create an upward force called lift that powers it into the sky.

The principle of the jet engine is not new; however, the technical advances necessary to make the idea work did not come to fruition until the 20th century. A rudimentary demonstration of jet power dates back to the aeolipile, a device described by Hero of Alexandria in 1st-century Egypt. This device directed steam power through two nozzles to cause a sphere to spin rapidly on its axis. It was … Web25 sep. 2015 · As the engine is started, the engine ingests air whose cross sectional area is greater than the engine frontal area. Near ground, this includes ground as well and induces a flow there. As air nears the engine, it is accelerated and if some amount of vorticity is already present, it forms an inlet vortex, which become visible under some conditions.
WebDescription. A geared turbofan engine is a variant of a conventional turbofan engine in which a reduction gearbox is installed between the fan and the low pressure (low speed) turbine. In a conventional turbojet engine, the fan, low pressure compressor and low pressure (low speed) turbine are all rigidly joined by a single shaft.
