Question 1

According to Bernoulli's principle for incompressible, non-viscous fluid flow, what happens to static pressure when airflow speeds up through a contraction in a streamtube?

Static pressure decreases while dynamic pressure increases. Static pressure increases while dynamic pressure decreases. Both static pressure and dynamic pressure increase proportionally. Static pressure remains constant while total pressure increases.

Correct Answer:

Static pressure decreases while dynamic pressure increases.

Question 2

How is dynamic pressure mathematically defined in subsonic aerodynamics?

q = 0.5 * rho * V^2 q = rho * V / 2 q = P_static + P_total q = 0.5 * P_static * V^2

Correct Answer:

q = 0.5 * rho * V^2

Question 3

What is the primary cause of aerodynamic lift generated by a symmetrical airfoil at a positive angle of attack?

Greater pressure reduction on the upper surface compared to the lower surface. Higher static pressure acting on the upper surface than the lower surface. Pure physical deflection of air downwards from the lower surface only. Increased air density above the wing relative to beneath it.

Correct Answer:

Greater pressure reduction on the upper surface compared to the lower surface.

Question 4

How does the boundary layer change as airflow moves along an airfoil surface from the leading edge to the trailing edge?

Transitions from a thin laminar layer to a thicker turbulent layer. Transitions from a thick turbulent layer to a thin laminar layer. Remains strictly laminar across the entire upper surface until the trailing edge. Remains strictly turbulent from the stagnation point onward.

Correct Answer:

Transitions from a thin laminar layer to a thicker turbulent layer.

Question 5

What defines the angle of attack (AOA) of a wing?

The angle between the chord line and the relative airflow. The angle between the longitudinal axis and the horizon. The angle between the chord line and the aircraft longitudinal axis. The angle between the flight path and the horizontal plane.

Correct Answer:

The angle between the chord line and the relative airflow.
