Question 7

Define dissymetry of lift:

Answer 7

Unequal lift across rotor disk resulting from difference in velocity of air over advancing blade and retreating blade.

Question 8

When blade flapping has compensated for dissymmetry of lift, the rotor down is tilted to the rear, called _________. The aviator uses ________ to compensate for dissymmetry of lift allowing him or her to control the attitude of the rotor disk.

Answer 8

1. Blowback
2. Cyclic feathering
