Thrust vectoring

Definition

Thrust vectoring is a technology used in aerospace propulsion that allows for the direction of the thrust produced by an engine to be changed, enabling enhanced maneuverability and control of an aircraft or spacecraft. This technique plays a crucial role in improving agility during flight, allowing vehicles to perform complex maneuvers and maintain stability during different phases of flight. By manipulating the direction of thrust, vehicles can achieve more precise movements and response to pilot inputs or automated systems.
