Dissymmetry of Lift - Effects

Effects

Unless countered, dissymmetry causes the helicopter to roll to the retreating side.

When dissymmetry causes the retreating blade to experience less airflow than required to maintain lift, a condition called retreating blade stall occurs. This causes the helicopter to roll to the retreating side and pitch up (due to gyroscopic precession). Once this dangerous condition arises, control may be lost, resulting in loss of the aircraft.

Famous quotes containing the word effects:

    “Like the effects of industrial pollution ... the AIDS crisis is evidence of a world in which nothing important is regional, local, limited; in which everything that can circulate does, and every problem is, or is destined to become, worldwide.”
    —Susan Sontag (b. 1933)

    “If I had any doubts at all about the justice of my dislike for Shakespeare, that doubt vanished completely. What a crude, immoral, vulgar, and senseless work Hamlet is. The whole thing is based on pagan vengeance; the only aim is to gather together as many effects as possible; there is no rhyme or reason about it.”
    —Leo Tolstoy (1828–1910)

    “to become a pimp
    Or deal in fake jewelry or ruin a fine tenor voice
    For effects that bring down the house could happen to all
    But the best and the worst of us . . .”
    —W.H. (Wystan Hugh)
