SU-57 Reveals 6 Innovations of the New Stealth Engine of the Russian Fighter That Promise to Revolutionize the Skies

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.

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…

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

Almost 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland. Houses form a continuous row, and behind them, narrow agricultural strips emerge, creating one of the most unusual rural patterns in Europe.

Júlia Pimentel, an 11-year-old from Minas Gerais, independently invented a new formula to calculate the square root using simple addition and multiplication, and her method was published in one of the most important mathematical scientific journals in Brazil.

They planted a sea of eucalyptus to produce cellulose, but the monoculture turned into a green desert, dried up springs and rivers, and pushed families out of regions in Minas Gerais and Bahia.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Without her own home and pressured by rent, a 25-year-old bought a small 15-meter boat, gradually renovated the interior by herself, transformed the interior with paint, new flooring, a larger bathroom, and started living on the canals, paying much less per month.

Heir bought 23,000 degraded acres in the Scottish Highlands, fenced the area, planted nearly 1 million native trees, and transformed empty mountains into a forest officially recognized after meeting 15 evaluation criteria over 20 years.
