4.6.1.1 over-wing propulsors

Over-wing propulsors refer to a type of propulsion system where propellers or fans are mounted above the wing, typically in a configuration that allows them to blow air over the wing's surface.
This design enhances lift by increasing airflow velocity over the wing, which reduces pressure above the wing and improves overall aircraft efficiency and performance.
Over-wing propulsors can be particularly beneficial for short takeoff and landing (STOL) aircraft, as they generate additional lift at low speeds, enabling shorter runways and more versatile operational capabilities.
