Basics of Aerodynamics


Due to propulsion (or thrust), the aircraft moves forward. The higher the propulsion, the faster the aircraft becomes, i.e. the higher the speed.
The thrust is generated by the propeller or turbine of the aircraft. How a propeller and a turbine work exactly is explained later in special sections.

Without propulsion, the aircraft wing cannot develop any lift effect. How this works is explained on the next page.
