A new engine for the Pakistani JF-17 fighter jet, dubbed RD-93MA being developed by Russia’s United Engine Corporation (UEC)-Klimov has entered thermal chamber tests to confirm high-speed characteristics in simulated flight conditions.

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

With the successful completion of the thermal chamber test stage, it will be possible to proceed to flight design tests. A set of tests in the TsIAM large thermal pressure chamber will be held as part of the experimental design work on the RD-93MA, a UEC statement said today.

During the tests, the engine will simulate conditions as close as possible to actual flight. Here, the BARK-93MA, the automatic control system of the engine, designed and manufactured at UEC-Klimov, will also be put to test.

The thrust of the RD-93MA is expected to 9300 Kgf compared to 8300 kgf of the RD-93, a significant bump-up in power which will help the JF-17/FC-1 to carry more armaments and fly at a higher speed (this information is not from UEC but earlier published sources).

The RD-93MA engine is distinguished by improved operational characteristics, increased thermodynamic parameters, a larger fan and an upgraded automatic power plant control system. The main engine parameters are also enhanced- the assigned resource and thrust, an emergency engine start mode is provided, and the possibility of emergency fuel drain is realized.” the statement said.
