А можно с этого места подробнее?
Или речь идёт о пересечении (встречи) лопастей?
Ну да, о нем и идет.
Если один ротор меняет угол относительно другого, рано или поздно их лопасти неизбежно встретятся. На микросоосниках еще хуже, там встречаются нижний ротор и флайбар верхнего ротора. Что приводит к мгновенному падению модели.
Термин не имеет прямого отношения к “перехлесту” в смысле совместного вращения винтов на вертах типа чинук и т.п. Чисто модельный жаргон…-)
