As part of the PAK FA program, tests of the second stage engines, known as the “Product 30” or “Type 30” for the multifunctional fifth-generation Russian fighter Su-57, are ongoing.
Judging by the appearance on the network of high-quality photographs of the new engine (the “toothy” left engine) taken during the tests, Sukhoi Design Bureau is currently undergoing active air tests of the “Product 30”.
Photos were taken March 16 by a professional photographer Mikhail Polyakov and posted on his page in the social network VKontakte.
“Product 30” (the so-called second stage engine) is a completely new power plant in which, according to a representative of the United Engine Corporation, many innovations have been introduced. Many of them do not have a close analogue in the world.
The installation of these engines on serial Su-57 fighters is planned in 2023-2025.
The exact characteristics of the new engine are kept secret, but it is known that the features of the new unit should enable the aircraft to accelerate to 1,5 Mach numbers (more than 1800 km / h) without turning on the afterburner.
The maximum thrust of the engine is expected to be 18 tons and should exceed similar indicators of 15,8 tons for its closest competitor - the Pratt & Whitney F119 engine, which is installed on the fifth-generation American fighter F-22.
