METHOD OF DETERMINING AEROFOIL SECTION LIFT AND DRAG, PREDOMINANTLY, OF AIRCRAFT WING

摘要

FIELD: aircraft engineering. ^ SUBSTANCE: proposed method comprises computer imaging of wing shape, effects of external forces brought about by ram airflow at angle of attack onto airfoil section 1 with bottom and top surfaces respectively. Lift is determined by combined equations with due allowance for wing area, curve factor, ram airflow density and speed. ^ EFFECT: higher accuracy. ^ 3 dwg
