The RD-33 turbojet
engine is one of the best bypass engines of the fourth generation in its thrust class.
The engine powers the well known Russian MiG-29
fighter and its modifications. This fighter powered by the
RD-33 engine has been awarded the Lenin
Prize and the State Prize of the Soviet union. The nozzle with thrust vectoring was
developed to improve the MiG-29 fighter performance.
At present the RD-33N
modification is developed to power the single-engine aircraft (the MiG-21). Other
SMR-95 for updating of French Mirage III and Mirage F-1 fighters;
RD-93 to power the new Chinese Super-7 fighter.
The engine is of modular design. This allows to master engines
local repair with modules replacement instead of replacing engine as a whole.
Due to its high stability the RD-33 doesn't
limit the aircraft piloting, features high rate of thrust increase
at flight speed that is of special importance for a combat fighter.
