Käännös:
Today, the concept of thrust vectoring better known in the context of modern jet fighter aircraft with high maneuverability. These nozzles are divided into flat / round and two dimensional / three dimensional. The first was a flat two-dimensional nozzle. In the USSR it developed in Ufinském research and factory Chief Designer Alexei A. Ryznovat as experimental engines for Al-31F aircraft Su-27. In the US, married with a flat nozzle thrust reverser tested on a test of the F-15S / MTD (Short Takeoff and Landing Maneuver Technology Demonstrator, the first flight 10. 5. 1989), America's first mass-produced aircraft with flat-vectored nozzle will be F-22.
A disadvantage of flat nozzles is about 14 to 17% less power, because the gas stream must be at a very short distance from a reshaped round (turbine) to the flat, then the disadvantage is less need to adjust the airframe unconventional nozzles.
Flat nozzle are merely two-dimensional - current rotating in a vertical plane.
