What is the Thrust Vectoring ?


Thrust Vectoring commonly know as Thrust Vector Control (TVC), is the ability of an aircraft, rocket and any other vehicle to change the direction of the thrust from its engine and motor to control attitude or angular velocity of the that particular vehicle.

Thrust Vectoring is the primary means of attitude control in rocketry and ballistic missiles because they fly outside of the atmosphere.

It was originally developed to provide upward vertical thrust to the aircraft, For aircraft vertical-takeoff-and-Landing and short-takeoff-and-landing. Thrust Vector provides more maneuverability to aircraft in combact, and can perform various maneuvers which aren't possible by conventional controls.

Methods of Thrust Vectoring.

Gimbaled Thrust

Gimbaled engines or nozzles in this method thrust Vectoring by liquid rockets is achieved by gimbaling the entire engine. This moves entire combustion chamber for thrust Vectoring or even moves entire assembly.

Later this method was developed for solid propellant achieves thrust Vectoring by only moving nozzles of the rocket using electric actuators or hydraulic cylinder.

The good example of its is STS SRBs uses gimbaling vector.
