Quiz: 5 Questions To See How Much You Know About Aerodynamics

Boldmethod

Let's take things up a notch!


  1. 1) When an airfoil increases in angle of attack, the stagnation point on the airfoil...

    The stagnation point moves down toward the bottom of the leading edge, which is why stall warning vane/tabs are located there.

    The stagnation point moves down toward the bottom of the leading edge, which is why stall warning vane/tabs are located there.

  2. 2) You're doing steep turns at 60 degrees of bank. The aircraft's weight is 2,500 lbs, and Vs1 is 54 knots. What is the apparent weight of the aircraft, and what is the new stall speed at this bank angle?

    During a 60 degree bank, your load factor is 2 Gs and your stall speed increases by 40%. So the apparent weight of the aircraft is 5,000 lbs, and the new stall speed is approximately 76 knots.

    During a 60 degree bank, your load factor is 2 Gs and your stall speed increases by 40%. So the apparent weight of the aircraft is 5,000 lbs, and the new stall speed is approximately 76 knots.

  3. 3) As air passes over an oblique shockwave, what happens to the velocity, static pressure and density respectively?

    When air flows over an oblique shockwave, velocity decreases, and static pressure as well as density increase.

    When air flows over an oblique shockwave, velocity decreases, and static pressure as well as density increase.

  4. 4) One negative characteristic of swept wings is the location of the stall, which begins at the ________.

    On most unmodified swept wing aircraft, stalls begin at the wing tip near the trailing edge.

    On most unmodified swept wing aircraft, stalls begin at the wing tip near the trailing edge.

  5. 5) You're flying with a friend, and you want to show them how you can bank the aircraft without using the ailerons. You step on the right rudder, and the aircraft yaws/banks to the right. You take your foot off the rudder and the airplane starts slowly rocking back and forth until it's stabilized in straight and level flight. This is an example of _______.

    This is an example of both positive static and positive dynamic stability.

    This is an example of both positive static and positive dynamic stability.
