Klimov RD-33
From Wikipedia, the free encyclopedia
The RD-33 turbofan engine was developed in 1982 to power the Mikoyan MiG-29 fighter. It's built by the Klimov company in Russia and has several variants, including variants for longer life or vectored thrust. Its American equivalent is the F404.
[edit] Variants
RD-93 is a variant of RD-33 which will be used to power JF-17 / FC-1. According to JF-17.com "The most significant difference being the repositioning of the gearbox along the bottom of the engine casing."

HAL built RD-33
In 2005, Russia signed a $250 million deal with India to modernize engines for the MiG-29 fighters of the Indian Air Force. According to the terms of the deal, Hindustan Aeronautics Ltd HAL will make 120 RD-33 series 3 jet engines at its Koraput plant for the upgradation of MiG-29 fighters.
The engine designer, St. Petersburg-based Klimovv, is also one of the players in the deal with India. Both of them are part of the RAC MiG corporation.
In the first stage HAL is expected to make 120 engines, which would cost less than those directly bought from Russia.
This deal would help HAL master the assembly of next generation jet engines, including RD-33MK (Sea Wasp) engines for deck based MiG-29K naval fighters being acquired under the Gorshkov aircraft carrier deal.
It will also help develop thrust-vectoring engines for the MiG-35 fighters, which Russia is fielding for USD 28. billion Indian tender for 126 advanced combat jets, the daily writes quoting experts.
