Su-57 almost crashed, suspected due to testing new engine

Military forums such as Defence and Sina have just posted information saying that a prototype Su-57 stealth fighter has encountered a rather serious problem.

Specifically, during a test flight that took place on Wednesday, October 11 at 4:00 a.m. (local time), a prototype of the 5th generation stealth fighter Sukhoi Su-57 (model number unknown) encountered a relatively serious incident.

The incident caused the plane to shake and lose control, with a high risk of crashing. However, the test pilot was an experienced person and was able to bring the fighter back to base safely.

It is expected that the Russian Air Force will temporarily suspend further test flights of the Su-57 before the exact cause of the above technical error is thoroughly resolved and repaired.

It is known that this is not the first time the Russian Air Force's highly anticipated fighter jet has encountered technical problems, but this is a relatively sensitive time because Moscow has just announced the "5th generation standard" engine model for the Su-57.

This engine (code unknown) has very different external characteristics when placed next to the AL-31FN or AL-41F1S series currently equipped for the Flanker family of fighters.

This leads to the question of whether the Su-57 above had integrated a new type of engine and had just made its first flight when a technical error occurred.

If that is the case, the prospect of completing the Su-57 program by 2019 is quite remote.

After the above incident, Russian media suggested that the Ministry of Defense should thoroughly complete the Su-57 before accepting it into service to avoid the situation of the price being increased many times while the technical errors have not been completely fixed like the case of the F-35, because clearly Russia's financial potential cannot be compared with the US to continuously "put out the fire".

It is not even possible that it will take another 10 years for this 5th generation fighter to be truly completed. If that is true, Russia's PAK FA program will be 30 years behind the F-22, and may even fall behind other stealth fighter models such as China's J-20 or Japan's F-3.
