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:

    Let us learn to live coarsely, dress plainly, and lie hard. The least habit of dominion over the palate has certain good effects not easily estimated.
    Ralph Waldo Emerson (1803–1882)

    One of the effects of a safe and civilised life is an immense oversensitiveness which makes all the primary emotions somewhat disgusting. Generosity is as painful as meanness, gratitude as hateful as ingratitude.
    George Orwell (1903–1950)

    Consider what effects which might conceivably have practical bearings we conceive the object of our conception to have. Then our conception of these effects is the whole of our conception of the object.
    Charles Sanders Peirce (1839–1914)
