PFI 1971 - May - Second Commission Meeting

Six weeks later, in May 1971, it held its second meeting on the subject of the TFIs. Here's how O.S.Samoylovich described this event: "One and a half or two months the second meeting of the NTS. I just said a little part of the posters, and the MiG company has had time to prepare a new version of the layout. It was the integrated circuit is very similar to the now existing MiG-29. Interestingly, the MiG company has received a copyright certificate for the integrated layout fighter aircraft before CB PO Dry. Subsequently, we had to spend a lot of effort to get a copyright certificate for the Su-27.

"Following two meetings, the Yakovlev Design Bureau was excluded from the competition, and the question arose of carrying out the third round, which did not need any company MiG or Su firm - this constant hassle, trying to find out what is on the "other" company".

Actually, OKB Mikoyan really came with the presentation of the integrated layout variants of the MiG-29, but it happened a bit later - in the second half of 1972. Most importantly, no official decisions about reducing the number of participants at that meeting had been adopted, and advance projects of the contest continued in the same part of "contestants". Of course, it is possible that in the MAP at an informal level Yakovlev was not perceived as the favorite and, especially, as the winner of the competition, but to exclude it from the participants at this stage would not make any sense. The choice was to make the customer himself.

In late summer of 1971, set to expire by the order of the period of development of preliminary design. Judging from the existing documents, the Sukhoi Design Bureau managed the appointed date: the end of September 1971 was basically completed the preparation of preliminary design for the T-10 and advanced materials sent to the MAP for the subsequent presentation of the Air Force. Soon the board of MAP met, which considered the readiness of all three materials for the presentation of EDO their customer.

It should be noted since that the MiG-29, presented in the preliminary design was in a different form than currently known MiG-29. In the pilot project it is different from the Su-27 is insignificant - practically projects Su-27 and MiG-29, were two of the same aircraft. But the Yak-45 differed from the Su-27 and MiG-29 significantly.

Speakers from the Mikoyan Design Bureau, Yakovlev and Sukhoi told about their aircraft, presented in a preliminary design, and answered questions. The main questions asked by the Minister of the speakers - is the level of maneuverability of the aircraft: the rate of climb, acceleration time from 600 to 1100 km / h at an altitude of 1,000 meters, disposable overload. With regard to questions of equipment and weapons, they practically all said the same thing.

The process of answering the questions was particularly notable for one episode. The Minister asked all speakers is the same first question: "What is the rate of climb for your plane?". Speaker of the OKB Mikoyan responded: 360 m/s. Speaker on the Yak-45 claimed 450 m/s. Rapporteur for the Su-27 was Oleg Sergeyevich Samoylovich. Involuntarily, observers expected an answer from him - more than 500 m/s, because the answer that climb the Su-27 is lower than that of the Yak-45 would be unwise. Oleg Sergeyevich came out of this situation brilliantly. He said: "In our OKB it was assumed that climb can not be greater than the speed of flight. Therefore climb the Su-27 - 300 m/s."

The board decided in essence that the preliminary design on all three planes were made in accordance with the TTZ and in full, it remained to present preliminary design for the Air Force.
