In the US, the unusual sound of the engines of the Russian Su-57 is being discussed

The American popular science magazine Popular Mechanics drew attention to a video of four fifth-generation Su-57 fighters flying at low altitude. The authors from the United States were attracted by the unusual sound emitted by aircraft engines.

You can hear for yourself what high-frequency sound these fighters make when approaching. He reaches an eerie crescendo as planes come into view.

- writes the American media.

There is an assumption that the video was made during the rehearsal of the extreme Victory Parade or on the day of the most solemn event in Moscow in June 2020. It was then that 4 Su-57 units were spotted simultaneously.

Now the Russians have 11 pre-production prototypes of the Su-57 and 1 production copy, which was transferred to the troops in December 2020. Initially, the military wanted to buy about 200 of these fighters, but so far they have ordered 76 units. They are waiting for the "Product 30" to appear - a new power unit that will make supersonic cruising speed.

      There is nothing wrong with that, it takes some time to catch up, the main thing is that the Su-57 has already been launched into serial production, we will wait for the engine of the 2nd stage and the annual production of the aircraft will be increased, Moscow was not built right away either !!!

      The latest production F-22 Raptor left the Lockheed Martin factory in 2011. Production is mothballed. A total of 195 aircraft were produced, of which 187 were in service.
      Planning to release the F2000s under 22, the United States stopped at 195. And the sect of "witnesses to the infallibility of the F22" still flourishes.

      F-35 is a crude machine launched into series with very dubious combat qualities, the invisibility of the F-22 is also questionable, and without it, this is an ordinary plane, without a horizontal thrust vector of the engines, which puts it in close combat in a deliberately losing situation

      And how much in reality will be able to rise into the air? We also have tens of thousands of tanks, but they will not all march to the English Channel. No need to measure spherical horses in a vacuum. In addition, the F-35 will have a dozen workers. And those are no better than the F-15. Stealth there is still a linden with modern AFAR. And how many pilots will be able to fully manage this unfinished trash and not crash for their own reasons? I don’t see that even in the world they flew especially on duty. So units fly with old stuff. They have one or two sorties for a serious distance, and then repairs for a week. So reality can simply be reduced by an order of magnitude.

    Why did you decide that it was "the sound of engines"? ))) Have you heard the sound of a crane or swan wedge? So this one is born in the same way ... With the only difference that Sukhoi has a constant at low speeds and flaps in a certain position, and in birds it is amplitude from the flaps of the wings.
