Вот ещё наводка
Огромная тема целиком посвящённая пректу Орлова “Воздушный извозчик”
На первый взгляд профиль что-то из NACA (~NACA 2414). Толщину считаем из чертежа, кривизну подбираем.
Весьма похож, naca2415, нижнюю часть “подровнять” немного нужно 😃

Douglas DC-3 (C-47, C-53, R4D, XCG-17) NACA 2215 NACA 2206
то что нужно 😃
Действительно очень похож на NACA-2415. Сам давно использую этот профиль на тренерах и на копийных радиобойцовках 1/12. Только хорошие впечатления!
