Images show Russia 's Sukhoi Su-57 Felon fitted with a new type of thrust-vectoring engine nozzle.

The radical-looking exhaust design is intended to improve the low-observable features of the Felon .

Images also appear to show the vectoring vented vented, which cool the exhaust and the aircraft’s infrared signature.

The AL-51F-1 was developed as a clean-sheet’ design, intended to offer increased thrust, lighter weight and lower operating costs.

The AL-41F-1 engine has been developed for the Sukhoi S-70 Okhotnik heavy subsonic uncrewed combat air vehicle.

The two -dimensional nozzle is intended to reduce the infrared and radar signatures, but it’s far simpler, without any vectoring controls.

The flat nozzle version of the AL-51f-1 is also being developed for another version, the T-50M , also known as the Su-57M.

If Russia orders more Felons , then this could help kickstart the development of the Su 57M.
