Why did they come up with thrust vectoring?
June 15, 2009 2:52AM
Thrust vectoring was designed to enhance the aerial performance of (primarily) combat aircraft. While some jet engines are capable of 2-Dimensional thrust vectoring (pitching up and down of the nozzles to aid in lift and y-axis maneuverability), there are a few highly advanced jet aircraft, such as the F-22 Raptor and F-15 ACTIVE, that utilize 3-Dimensional vectoring. This third dimension allows aircraft to angle their engines' thrust sideways to highten x-axis turning power (and opposite vertical on twin engined models for z-axis roll assist). The ability to control the direction of thrust and afterburning output can lead to supermaneuverability, which is 'the ability to perform beyond the physical limits of standard control surfaces.' Simply put, a vectoring aircraft makes a formidable fighter in any combat situation. Even when it comes to the ground (literally), the simple 2D vectoring is useful for STOL (short take-off and landing) and/or VTOL (vertical take-off and landing), which allows for shortened runways and less reliance on wing-generated lift.
