What is Understanding Helicopter Drag Types about?
Total drag on an aircraft is the sum of parasitic, profile, and induced drag. Parasitic drag comes from non-lifting parts and increases with speed. Profile drag results from friction of rotor blades passing through air, comprising form and skin friction drag, and increases moderately with speed. Induced drag is caused by downward airflow from lift production.
