What is Thrust Vectoring and its applications? Does anyone who can explain it ?
cronxeh said:Thrust vectoring is directing output stream using nozzles.
Applications? SU-37 has the best thrust vectoring example

Those nozzles can move around and direct the exhaust and therefore make sharper and faster turns on an airplane
Another example of thrust vectoring is on F/A-22, and F/A 18 (I think)
cronxeh said:I stand corrected. However, NASA did modify it to make an experimental F-18 HARV
http://www.nasa.gov/centers/dryden/research/HARV/rd.html I'm not sure where I've seen the thrust vectoring F18 but this could be it..
Nenad said:so the after burners do not increase the turbofan rpm, or the turbine rpm. It just combusts and uses the extra exhaust gas as a thrust force, kind of like on a rocket.
Is this correct?

Initial US involvement with the Harrier began in 1957 when Hawker’s revolutionary design was met with disinterest by the British government and a lack of government funding to proceed into development. By that time, the US had conducted extensive research on numerous competitive concepts for V/STOL flight, including aircraft-tilting (tail sitters), thrust-tilting (tilt rotors), thrust-deflection (deflected slipstream), and dual-propulsion (lift-cruise engines) concepts. The simplicity and elegance of the rotatable nozzle vectored-thrust concept of the P.1127 so impressed NASA Langley management and researchers that a formal agreement for cooperative testing was initiated with Hawker under the Mutual Weapons Development Program of NATO.
Thrust vectoring is a technology that allows for the manipulation of the direction of a jet engine's thrust to control the orientation and movement of an aircraft.
Thrust vectoring works by using movable nozzles or vanes on the jet engine to redirect the exhaust gases and change the direction of the thrust. This can be done through mechanical, hydraulic, or electrical systems.
The main benefit of thrust vectoring is enhanced maneuverability of the aircraft, allowing for tighter turns and improved stability. It also allows for shorter takeoff and landing distances, and can improve overall engine performance.
Thrust vectoring is commonly used in military aircraft, such as fighter jets and bombers, to enhance their agility and combat capabilities. It is also used in some commercial aircraft and experimental aircraft for research purposes.
While thrust vectoring offers many benefits, there are also some limitations. It can add weight and complexity to an aircraft, and may require additional maintenance. It also has limited effectiveness at low speeds and altitudes.
