Russia Developing New RD-93MA Engines For Pakistani JF-17 Thunder Fighter Jets

A Russian state-owned United Engine Corporation is developing new RD-93MA engines for pakistani JF-17 thunder fighter jets.

UEC controls the development and manufacturing of all engines for military, civilian, and space use in Russia and for Russian exports.

The RD-93MA has been specially developed to power single-engine fighter jets. It is an upgrade of the RD-93 engine which currently powers the Pakistani JF-17 and Chinese Chengdu FC-1 single-engine fighter jets.

In a press release on its website on Wednesday, UEC said the RD-93MA engine had been shipped from St. Petersburg to Moscow for thermal pressure chamber trials at the Central Institute of Aviation Motors (CIAM). The pressure chamber trials at CIAM are expected to subject the RD-93MA engine to simulated heat and altitude conditions the power-plant would experience in actual flight.

The UEC press release states, “The RD-93MA engine has improved performance. In particular, increased thermodynamic parameters, an improved design of the fan and the hot part, an upgraded automatic power-plant control system… An additional emergency engine start mode was provided… and the possibility of emergency fuel drain was realised. All this is due to the specifics associated with the possible use of the power-plant on a single-engine aircraft…”

The reference to use in single-engine aircraft has given rise to speculation that the new engine is destined for the JF-17 fighter. This is because Russia does not have any active single-engine fighter project at the moment.

After the successful completion of the thermal chamber test, the next phase will begin for flight design tests. A number of tests in the TsIAM large thermal pressure chamber will be carried out as part of the experimental design test on the RD-93MA, a UEC statement said.

During the tests, the engine will simulate conditions of actual flight for further testing with BARK-93MA, the automatic control system of the engine, designed and manufactured at UEC-Klimov.

These new engines will power Block III of JF-17’s.

According to reports, the RD-93MA engine can produce maximum thrust of 9,300 kgf (kilogram-force). The RD-93MA would have significantly greater thrust than the existing RD-93 engine used on Pakistan’s JF-17 fighter, which can produce maximum thrust of 8,300kgf, according to UEC.

Having a new engine offers advantages in addition to increased thrust in combat situations. In December, Chinese state media confirmed that the latest version of the JF-17, dubbed the JF-17 Block 3, had made its maiden flight. The upgraded fighter will have new electronically scanned radar and other electronics, all of which necessitate higher power requirements than can be met by the existing power-plant.

Pakistan has already built over 100 JF-17 fighters for its air force and officials have indicated 62 JF-17 Block 3 fighters will be ordered by 2024.

In 2015, IHS Jane’s Defense Weekly reported Pakistan would continue to use Russian engines for the JF-17 even though China was developing an alternate engine. “We are completely satisfied with this Russian-made engine,” an official Pakistan Aeronautical Complex had told IHS Jane’s Defense Weekly. Pakistani officials had claimed “changing to another engine would not make any sense and would be disruptive and cause a huge expense for the JF-17 programme”.

Interestingly, the RD-93 has a connection to India. The RD-93 is developed from the RD-33 engine that powers the MiG-29UPG fighters of the Indian Air Force and MiG-29K jets of the Indian Navy. India operates over 60 MiG-29UPG jets and about 40 MiG-29K fighters. The government recently cleared the purchase of 21 MiG-29 fighters for the Indian Air Force.

Despite repeated Indian protests in the past two decades, Russia has continued supply of the RD-93 to China and Pakistan

  1. Pakistani JF17 with block building measures and the integration of Chinese and Russian engine’s will make this war machine more lethal and potent.
    Already 27 Feb, we have seen how potent this JF17 is and how it destroyed the Indian Airforce jets during the clash..
    Above all the Pakistani pilots are highly skillful and highly trained in aerial combats and a lot of history is witness to this fact..
    Great to watch, when this war machine gets ready..
