airfoils - 2024 PLAYTIME - Buzzpoints App

Question

The simplified theory of the “thin” kinds of these devices relates their angle of attack to the generated lift in terms of their camber. For 10 points each:

[10e] Name these streamlined bodies capable of producing more lift than drag, thus permitting flight.

ANSWER: airfoils [or wings or aerofoil]

[10h] This scientist names an airfoil generated as the image of the unit disk under a namesake conformal map. With Martin Kutta, this scientist calculated the lift on an airfoil moving at constant speed in terms of the circulation.

ANSWER: Nikolay Joukowsky [or Nikolay Yegorovich Zhukovsky]

[10m] The Kutta-Joukowsky theorem may be viewed as a version of this effect with rotation coming from the fluid instead of the airfoil. In this effect, a spinning object is deflected by lift generated due to a pressure gradient force.

ANSWER: Magnus effect [accept Magnus side force]
