Поправки циркуляции крыла от влияния мотогондол и фюзеляжа.
Для получения значений поправок циркуляции от влияния мотогондол и фюзеляжа можно использовать значения из таблицы 4.4, испульзуя в качестве аргумента коэффициент подъемной силы крыла. Этот коэффициент нам либо задан, либо вычисляется по формуле
, (4.1)
где nр – расчетная перегрузка;
G – вес самолета;
S – площадь крыла;
q – скоростной напор.

Приложение 2.
В данном приложении приводятся расчетные характеристики некоторых авиационных профилей. Характеристики приведены только для учебных целей. Профиля в таблице расположены по порядку увеличения площади в целях удобства использования таблиц студентами. Приведены следующие характеристики:
F – площадь профиля;
i2 – квадрат радиуса инерции;
z – ордината центра тяжести профиля;
N – порядковый номер профиля.
Также приведена таблица толщин листов, применяемых в обшивках.
