14.82 Forces Acting on a Helicopter Rotor

14.82.2 For a nil-wind hovering condition identify the following vectors:

(a) rotational flow;

(b) induced flow;

(c) relative airflow.

14.82.4 For a nil-wind hovering condition identify:

(a) pitch angle;

(b) inflow angle;

(c) angle of attack.

14.82.6 For a given blade section identify the total aerodynamic reaction force (TR) and its components; rotor thrust and rotor drag.

14.82.8 Define total rotor thrust, and total rotor drag (torque).
