Su-57 tested with square nozzles.
Slightly different from the F-22 is what I hear.

In Russia, a robotic platform "Venom-Totem" was developed for evacuating the wounded, as well as delivering supplies and ammunition to the military. The robotic platform "Venom-Totem" was created in Novosibirsk by the ROBCOM company. Initially, the unmanned platform "Venom-Totem" was developed for evacuating victims from emergency zones, but recently it has also been used by the troops. It is planned to transfer 50 more units to the troops in the near future. The "Venom-Totem" platform has an electric drive and is controlled remotely, it is capable of carrying a load of up to 500 kg. The platform speed is up to 5 km / h, the operating range is up to 200 meters. In the future, it is planned to create platforms that will be able to automatically load the bodies of the dead and remove them.

The first footage of the Russian Su-57 aircraft with a flat nozzle on its engines. The footage shows that the test Su-57 is equipped with only one new AL-51F1 engine with a flat nozzle, the second engine is the standard AL-41F1 power plant. The new Su-57 nozzle has four independently controlled flaps, two of which are designed for use in subsonic mode and two for supersonic flight. The flat nozzle is also installed on the US F-22, but it has only one thrust vector, while the Su-57 has a nozzle with an all-aspect thrust vector, which provides better maneuverability and better control of the aircraft. The design of the new nozzle allows for better cooling of the exhaust gases. This, in turn, reduces the infrared signature of the aircraft in the rear projection. It is worth noting that the "Flat" nozzle will reduce the thrust of the Su-57 to some extent, but it will improve the stealth characteristics from the rear projection of the aircraft. Currently, the Su-57 aircraft uses the first-stage AL-41F1 "Product 117" engine; Su-57s with second-stage AL-51F1 "Product 30" engines should be installed from 2025. The AL-51F1 has several non-afterburning modes, in which the fighter will operate at high supersonic speeds and will be less visible in the infrared range. An improved version of the fighter should be designated Su-57M. According to experts, the new engine will provide the Su-57 with the highest level of thrust among all fighters in the world currently in use.
