The trials of Russia’s fifth-generation fighter jet Su-57 (PAK FA, the Perspective Aviation Complex of Frontline Aviation) will last several years, President of Russia’s United Aircraft Corporation Yuri Slyusar told TASS on Thursday.
“They [the trials] have just begun. They will, of course, last several years,” he said.
The Russian fifth-generation Perspective Aviation Complex of Frontline Aviation (PAK FA, also known as the T-50) fighter jet took to the skies for the first time in 2010. As was reported earlier, the cutting-edge fighter performed its first flight with a new engine on December 5.
Currently, the so-called first stage engine 117S is mounted on the Russian fighter. A new engine has not yet received its name and is conventionally designated as the second stage engine.
