U.E.C.- Russian aircraft engines

So they still have less infrastructure for jet engine building than the West. And probably less than Russia as well. wrote:

Russia may have overtaken the West when it comes to building engines for tactical aviation. Currently, the West does not have an engine at the level of the AL 51F1? The F 119 is an older design with lower performance? Maybe the F 135?

Program suspended as such type of engines would have not any particular utility in the F-35. Its better advantage could be to allow supercruise but such a regime would have not any utility for a plane that could just reach mach 1.6 anyway. wrote:

It will be for the NGAD program.

n theory the US has more advanced engine technology than the F135 at the test stand. wrote:

It follows that the US can still be the leader in the field of aircraft engines. China will probably catch up and overtake Russia in this respect in a few years or a decade, and maybe even the US.

And everyone is searching for variable cycle engines now and could be that the Su-57M would be the first one to get it anyway. wrote:

Do you think the AL-51F1 has a variable cycle bypass? The Russians have already created prototypes of such an engine, it was the AL-41 for the MiG MFI.

hey are working on it but as a further upgrading, they have still to field the basic version. wrote:

It will definitely take another decade. Look how long they have been working on the AL-51 and there is no end in sight. It is not known when we will see it on the serial Su-57. At one time, the Russians developed this technology on the AL-41 and the US on the YF 120 for the F-22 or F-23, but they chose the cheaper and less complex option F 119.

The Su-57 is the best 5th generation aircraft out there. As simple as that. The F-35 has pathetic top speed and anemic internal volume for weapons. Which means if it is to be used for long distance combat they must use it the so called "Beast Mode" where it will light up radar screens like a Christmas tree with external stored weapons. wrote:

You once mentioned that the Su-57 has on-board electronics that are not inferior to the F-35 and are even better. This is often the argument of Western fanboys. How is the F-35 incredibly packed with incredible electronics, radar, etc. This is their last line of defense after hard parameters such as maximum speed, operational range, kinematic capabilities, etc. in favor of the Su-57. I wonder how the Chinese J-20 compares to this. I doubt it could compete with the Su-57.

The world premiere of the Russian fifth-generation aircraft engine 177S took place in China, 11.13.2024.

Reduced fuel consumption in all operating modes allows to reduce the operating costs of the 177S engine. In addition, the engine provides increased energy consumption for powering the electronic systems of modern aircraft. The power plant also increases their flight range.

At the exposition, UEC is also demonstrating to foreign partners for the first time full-size models of the new AL-31FN engines of the fifth series and SM-100. In their creation, technologies and materials typical for fifth-generation engines are used.

The SM-100 engine has been developed in the size of the AI-225-25 and at the same time has a lower weight, as well as a thrust increased by a third - up to 3300 kgf. New design solutions allow to significantly increase the engine service life while reducing the thrust requirements, which reduces operating costs. Moreover, a modification for high-altitude unmanned aerial vehicles can be created on the basis of the SM-100 engine.

Serial engines of the AL-31F/FN/FP family for multi-role fighters have received a modernized appearance — series 5. The new modification of the AL-31FN engine, which was first presented by UEC, was developed specifically for single-engine aircraft and has increased reliability. The use of the engine will expand the potential of aircraft in terms of flight range and altitude. This is ensured by increased thrust of up to 14 thousand kgf in takeoff mode and fuel consumption reduced by 6%.

When creating modern engines, UEC designers use the latest technologies and materials, and most importantly, new approaches, said UEC CEO Alexander Grachev.

"The engines presented in China can be classified as fifth generation in many characteristics. Moreover, breakthrough design solutions allow them to be optimized to customer requirements and expand the range of options. The undoubted advantage of the new Russian engines is the ability to upgrade previous generation engines to the most modern version during a major overhaul. At the same time, their service life or thrust can be increased."

At the exhibition, UEC is showing a full-size model of the new VK-1600 V engine for medium helicopters and the TV7-117ST-01 turboprop for regional aircraft. A hybrid-electric power plant based on the new VK-650 V aircraft engine is also on display. The Russian engine-building corporation is also displaying a modernized RD-93MA turbojet with improved performance characteristics: thrust has been increased by 400 kgf, and the designated service life has been increased by a third.

In addition, for the first time abroad, a full-size fan blade for the PD-35 engine made of polymer composite materials was presented.

The composite blade weighs 30% less than one made of titanium. UEC designers developed the first Russian technology demonstrator engine PD-35 and used the latest technologies and materials in its creation. During testing, it confirmed stable operation when reaching the design thrust of 35 tons.

The International Aviation and Space Exhibition Airshow China 2024 will be held in Zhuhai from November 12 to 17, 2024. The exhibition will feature 890 companies from 47 countries.
