O novo motor furtivo do caça russo AL-51 F1 apresenta um bico de exaustão angulado e achatado, que melhora significativamente as características furtivas do SU-57 ao reduzir a assinatura de radar e térmica. Além disso, o AL-51 F1 oferece vetorização de empuxo bidimensional, focada no controle de inclinação, aumentando a manobrabilidade e permitindo curvas mais fechadas e operações em baixas velocidades.

The SU-57 Fighter Jet Presents 6 Advancements of the New Stealth Engine of the Russian Fighter, Including Thrust Vectoring and Enhanced Design, Promising Revolution in the Skies

For the first time, the Russian fighter SU-57 has been equipped with a new stealth engine. The highlight is a new type of engine nozzle with thrust vectoring, whose angled and flattened design aims to enhance the stealth characteristics of the SU-57. This technological advancement will be integrated into the AL-51 F1 engine in the upgraded version, the SU-57M.

So far, the SU-57 used the AL-41 F1 engine, the same one present in the SU-35 fighter. However, this configuration is not ideal for stealth aircraft.

Engines for fighters of this type generally have serrated edges to reduce radar reflection and create a turbulence that mixes hot gases with the cold air around. This decreases the aircraft’s thermal signature, making it more difficult to detect by passive systems like IRST.

The new stealth engine of the Russian SU-57 fighter features an angled and flattened exhaust nozzle, similar to that used on the American F-22 Raptor, aiming to reduce radar and thermal signatures. Both engines incorporate thrust vectoring, which significantly improves maneuverability and the ability to perform tighter turns during flight.

The major innovation of the new stealth engine of the Russian AL-51 F1 compared to the AL-41 is the capability of bidimensional thrust vectoring, focused on pitch control.

Unlike the AL-41, which allows for three-dimensional vectoring (pitch, yaw, and roll control), the AL-51 F1 significantly improves the maneuverability of the SU-57, allowing tighter turns and operations at low speeds, such as at the angle of attack.

This type of flattened stealth engine nozzle is already used in the American F-22 Raptor, making comparisons inevitable. However, the future of the SU-57M remains uncertain. It is unknown whether this new stealth engine of the Russian fighter will actually be integrated into the upgraded version of the SU-57 or when that will occur.

The advancement will heavily depend on future orders of the SU-57, which may drive the development of the SU-57M and lead to the mass production of the AL-51 F1 engine, currently just a prototype.

Ucrânia negociar a paz melhor para o seu povo, Ucrânia já está com dívida maior que o seu PIB em empréstimos do FMI e compra de armas.

Acho que pode ter um mal entendido no texto… Quem deve ter vetorização tridimensional é o novo AL-51 e não o anterior AL-41… Por favor corrijam e expliquem se eu entendi errado…
