RD-33

The RD-33 turbofan engine was developed in 1985 to power the Mikoyan MiG-29 fighter. It is a 8000-9000 kgf thrust class turbofan twin-shaft engine with afterburner built by the Klimov company of Russia and has several variants. It has an important feature of modular design, individual parts can be replaced separately and good tolerance to the environment make ease for field maintenance and retain performance in complex environment.[1]

[edit] 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 upgrade of MiG-29 fighters. The engine designer, St. Petersburg-based Klimov, 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 US $12 billion Indian tender for 126 advanced combat jets.

[edit] Variants

After years of development has built themselves an engine family. A newly designed thrust vectoring nozzle (TVN) is now available. New models of the RD-33 family include BARK digital monitoring and control systems. Repair and maintenance of RD-33 engines take advantage of an information and diagnostics system (IDS).

[edit] RD-33

Baseline model developed in 1985 to power the MiG-29.

[edit] RD-33 series 3

A revised model with a longer service life used on later or upgraded old variants of MiG-29 such as MiG-29M and MiG-29SMT.[2][3] A pair of RD-33 series 3 engine equipped with TVN is currently undergoes flight tests as a component of the MiG-29OVT jet fighter.[4]

[edit] RD-33B/NB

A model without afterburner for various types of aircraft.

[edit] SMR-95

SMR-95
SMR-95

A model for upgrading foreign 2nd and 3rd generation jet fighters. The accessory gearbox is refitted below the engine, length can be vary depends on the adopted aircraft body. The engine passed bench tests and flight tests on the Super Mirage F-1 and Super Cheetah D-2 aircraft of the South African Air Force and had achieved improved in flight performance and combat efficiency by a factor ranging from 1.2 to 3.0.[5]

[edit] RD-93

A variant use to power the 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."

[edit] RD-33MK

RD-33MK

The RD-33MK "Morskaya Osa" (Russian: Морская Оса: "Sea Wasp") is the latest model of the family. Developed in 2001, intend to power the MiG-29K and MiG-29KUB shipborne fighters, however it is also adopted by present MiG-35. The new engine features a 7% higher horsepower in compare to the baseline model due to the usage of modern materials on the cooled blades. It remains the length and maximum diameter while increase in afterburner thrust and dry weight to 9,000 kgf and 1,145 kg respectively. It also contains systems that reduce its infrared and optical visibility. Service life has now increased to a long 4,000hours. New modifications ensure shipborne fighters to take off from unassisted aircraft carrier deck, retain performance in hot climate environment and of course, a boost in combat efficiency of the latest variant of MiG-29 fighter family.[6][7]
