The trailing vortex is formed at each wing-tip as there is a circulatory motion established by the____

Viscosity

Air tornadoes

Flowing wind

Leaking flow at the wing- tips

Correct Answer : Leaking flow at the wing- tips

Explanation : The flow has a tendency to ‘leak’ around the wing-tips. This flow makes a circulatory motion that trails downstream of the finite weak, giving rise to trailing vortices. This flow is possible because of viscosity but it doesn’t happen because of viscosity.

Is loading distribution is represented by the sum of finite number?

True

False

Can Not Say

None of the above

Correct Answer : Option (A) : True

Explanation : In the collocation solution of the basic integral equation, the loading distribution is represented by the sum of a finite number of known functions with unknown coefficient substituting the loading representation into their result.

Is it difficult to predict the analytically overall amount of lift?

True

False

Can Not Say

None of the above

Correct Answer : Option (A) : True

Explanation : It is difficult to predict analytically the overall amount of lift that a wing of given geometry will generate. The lifting line theory yields the lift distribution along the span wise direction based only on the wing geometry and flow conditions.

Is prandtl lifting line theory is a mathematical model that predicts lift distribution over a three-dimensional wing?

True

False

Can Not Say

None of the above

Correct Answer : Option (A) : True

Explanation : The prandtl lifting line theory is a mathematical models that predicts lift distribution over a three dimensional wing based on its geometry. It is also known as the lanchester-prandtl wing theory. It was used to calculate lift on the wing.
