The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). Drag may be expressed as actual drag or the coefficient of drag. Drag curves are closely related to other curves which do not show drag, such as the power required/speed curve, or the sink rate/speed curve.

  • منحنى السحب هو العلاقة بين السحب على الطائرة والمتغيرات الأخرى، مثل الرفع أو معامل الرفع أو زاوية المواجهة أو السرعة. يمكن وصفه بمعادلة أو عرضه كرسم بياني (يسمى أحيانًا «مخطط قطبي»). يمكن التعبير عن السحب كسحب فعلي أو معامل السحب. ترتبط منحنيات السحب ارتباطًا وثيقًا بالمنحنيات الأخرى التي لا تظهر سحبًا، مثل منحنى الطاقة المطلوبة / السرعة، أو منحنى معدل الغرق / السرعة.
