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…

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

Elon Musk’s internet comes to mobile: Starlink technology connects smartphones without an antenna via satellite, works even without carrier signal, already costs just US$10 extra in the US, and could arrive in Brazil as an included benefit.

In Niger, mud buildings have stood for ten generations while the world spends billions on concrete and steel, now African architects are proving at the Venice Biennale and in real projects that red earth can be the smartest and most sustainable building material of the 21st century.

Seven world powers including the US, China, and Russia are spending €22 billion on a reactor in the south of France that aims to confine plasma at 150 million degrees Celsius, ten times the temperature of the Sun’s core, using a magnetic field capable of lifting an entire aircraft carrier.

Secret chamber sealed 4,500 years ago found in the Pyramid of Khufu, and Hawass announces its opening to the world in 2026

With a wingspan of 152 meters, 76 tires, and a capacity to carry 1,270 tons, the Boeing Pelican was the giant “flying ship” that promised to cross oceans close to the water on an invisible air cushion beneath its wings.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

Giant marine crocodile fossil found in the Sahara may change theories about extinctions in the Jurassic period

How to find out the number of tiles without making mistakes in the construction: a simple calculation shows why a gable roof might need 1,350.

Brazil copies the USA and Canada to create completely silent houses with filled panels that reduce construction time by up to 60%, eliminate thermal bridges, and allow for the construction of complete properties in a few weeks.

Psychologists and cognitive studies claim that children who watched Dragon Ball in the 1980s and 1990s developed a ‘decisive advantage’ related to empathy, social interpretation, and moral thinking.

Oil leaves behind water that is almost impossible to use, but solar technology in the USA promises to clean this residue before it is returned underground.

Japanese ship that “flies” over the sea draws attention by lifting the hull with underwater wings, using a turbine engine, and crossing routes to islands at high speed, reducing long trips and providing passengers with an experience similar to that of an airplane.

The weather may not be as perfect as it seemed: scientists identify a microscopic anomaly in fundamental structures of the Universe, and the discovery on extreme scales has a direct impact on theories about gravity and quantum physics.
