MOSCOW --- Another flying prototype of Russian fifth-generation fighter T-50 (also known as PAKFA - Russian for future tactical aircraft) flew for the first time in Komsomolsk-on-Amur on November 17, according to Internet sources saying the aircraft’s index is T-50-8.

Russian Deputy Defense Minister Yuri Borisov had said previously that the ninth T-50 prototype was about to start its tests. In all probability, he meant T-50-8, because the aircraft, designated as T-50-5 and damaged in flight in June 2014, was rebuilt using some of the components of the sixth PAKFA prototype (T-50-6) and re-designated as T-50-5R.

In addition, according to open sources, the first start of ‘Product 30’, better known as the PAKFA’s ‘second-phase engine’, took place early in November 2016. Yevgeny Marchukov, general designer/director of the Lyulka Design Bureau (an affiliate of UMPO), told its team in a greeting message.

"I congratulate the personnel of the corporation on the first start of Product 30," he said in the telegram.

As was reported in the press, the PAKFA’s second-phase engine will be 17% more efficient than the first-phase engine (Product 117) currently used for testing the T-50. The latest engine will feature lower specific fuel consumption and a reduced infrared signature compared to Product 117. -

MOSCOW --- The United Engine Corporation (UEC, a subsidiary of Rostec) has conducted the first start of the advanced engine (Product 30) designed to power the T-50 (PAKFA - Russian acronym for Future Tactical Aircraft), the corporation’s press office says in a news release.

"The test start has been a success. The engine demonstrator was started at the Lytkarino Machinebuilding Plant," the release says.

The engine is under development by the Lyulka Design Bureau under the supervision of General Designer Yevgeny Marchukov dual-hatted as director, UEC explained.

According to the corporation’s director general, Alexander Artyukhov, "advanced design solutions unrivalled in Russia’s engine-making industry have been used" to manufacture the demonstrator.

In addition to the technology demonstrator, several core engines of the sophisticated engine have been made for bench tests.

As was reported in the press, the advanced engine will start powering Russian fifth-generation fighter T-50 (PAKFA) on its sorties in the fourth quarter of 2017. The PAKFA’s maiden flight took place in 2010. The fighter is due to enter service in 2017. For the time being, the prototypes are equipped with the so-called ‘first-phase’ engines (Product 117).
