Вот это я вычитал недавно на сайте Тома Купера
And then, there were also major flaws not only in terms of basic MiG-23-design, but also in terms of solutions for its equipment. For example, the R-29 engine. Surely, there is no doubt that most of the engines from the 1960s were not up to the task of dogfighting. You can see that on example of TF-30 as well. But, hell, the R-29 was not even up to the task of anything else but acelerating the plane like a rocket. Why build an engine you actually can't stop at all - but have to leave it to decelerate on its own? In the case of TF-30, you could at least move the throttle "carefully" (to one degree or the other), but in the case of R-29, once you accelerated past Mach 1, and again past Mach 2, you couldn't decelerate it but had to wait until it slows down on its own.
Какие-то основания для таких страшилок были?Раньше я,наоборот,читал,что х-ки торможения у 23-х были вполне на уровне
И более общий вопрос -а на сколько эти х-ки вообще важны?
