Maxim Kuzyuk: PAK FA’s engine may be started without oxygen

The engine of Russian fifth-generation multi-role T-50 fighter (PAK FA) may be started without oxygen as against previous aircraft, which used oxygen feed system, RIA Novosti reports with reference to the CEO of Aviation Equipment Holding Company (part of Rostec), Maxim Kuzyuk.

“In the course of development of PAK FA we were tasked to ensure the “oxygen-free” engine start. Plasma ignition system is installed in combustion chamber and afterburner. The design of fuel nozzle was changed: in parallel with the fuel supply a plasma arc is generated,” Kuzyuk said.

He stressed that the engine start system and auxiliary power unit (APU) of PAK FA are “unique” and “have no analogues”. “So far all the ignition systems used oxygen feed systems in order to improve altitude performance and ensure safe engine inflight start; however, the system requires installation of an oxygen system and certain airfield infrastructure,” Kuzyuk said adding that his company is developing “a number” of components and systems for PAK FA fifth-generation fighter.

Aviation Equipment Holding Company is taking part in development of Russian-Indian fifth-generation fighter – FGFA (derived from PAK FA). Its engine will also be able to start without oxygen feed system.

  The presentation of the Ya-130M aircraft took place at the international military-technical forum "Army-2024", which was held from August 12 to 14, 2024 at the Patriot Convention and Exhibition Center. It should be noted right away that this is not just the modernization of the Yak-130 aircraft, but the transformation of a combat training aircraft into a full-fledged light combat aircraft. In the information field, this event was marked by a number of brief reports from federal news agencies. But the project, like the Yak-130 aircraft with its unique flight characteristics, deserves a more detailed review, which we decided to do.
