What is wrong with the Su-57 fighter. Problems Again - Hi-Tech Mail.ru:
Translated by google
In a sudden crash of one of the models, the fighter’s troubles do not end there.
The creation of intra-body missiles for the fifth-generation Russian fighter Su-57 turns into sudden problems for their developers. Such information was shared by Boris Obnosov, head of the Tactical Missile Weapons Corporation.
According to Obnosov, missiles for internal deployment require smaller dimensions, folding wings and rudders. In addition, the launch of a projectile from an enclosed space creates additional loads on the apparatus. Obnosov stressed that designers have to face such problems for the first time.
At the end of last year, the first production model of the Su-57 crashed during a test flight in the Khabarovsk Territory. A possible cause of the disaster could be another structural problem of the aircraft. According to sources, the cause of the disaster was the failure of the tail control system.
Some experts even refuse to consider the Su-57 a fifth-generation fighter. For example, Vadim Lukashevich, a former employee of the Sukhoi Design Bureau, emphasized that the car still had not received the engines of the second stage (“Product 30”), which would allow him to move at supersonic speed in the after-blow mode. Indicators of stealth aircraft also do not correspond to the level of the fifth generation.
The right to be called a fifth-generation fighter, the Su-57, was denied even in China, attributing it to the “4 +++” generation. And the American publication The National Interest in early January wrote that the plane is "not yet ready for full-scale military operations against a high-tech enemy." One of the main problems in this series of journalists called underfunding in the face of a reduction in the military budget. The authors also argue that until 2018 the aircraft did not have a complete fire control system and self-defense kit.
