...One of the most favourable inducements for us to embark on this program was the availability of the engines required for later type I-16 and the I-153 aircraft. The engine is still in use today in the huge numbers of Antonov AN-2 biplanes that are Russia's work horse. The ASh-62IR engine would have to have a reliability record, second to none, comparable with that of the venerable Pratt and Whitney that powered the very successful DC3. The 1000hp radial does an excellent job in the huge AN-2 biplane and does an incredible job on a twenty foot long fighter. One of the bigger problems we faced was the non-availability of propellers for these aircraft. The golden rule in Russia for a long, long time, has been that if you want something you have to make it, as opposed to scouring the world for some suitable substitute that may fit the bill. Quite a daunting task when you realise that two short blades have to absorb the same horsepower as four long blades on the AN-2. The last piles of paper work and drawings I saw during the design process were getting expensively high, but the end result is superb propeller blades with a cambered profile that perform exactly as per the design achieving thrust and static RPM at precisely the pitch setting the designer forecast. In the Moscow propeller plant they produced the two bladed propeller using the AN-2 hub and very cunningly reworking the vacant blade apertures and pitch mechanism.
Вкратце по винту - от Ан-2 использовали переработанную втулку и механизм изменения шага, а лопасти спроектированы и изготовлены для И-16 заново.
