TEST 1 - LIFT

Question 1

Bernoulli Effect, what is is & how it impacts lift

Answer 1

Static pressure, dynamic pressure, and potential pressure will always add up to the same constant value. Helps with lift because if the velocity of the wind at the top of the plane is higher than the bottom, the pressure will be lower on top

Question 2

Stall Speed

Answer 2

slowest speed a plane can fly to maintain level flight

Question 3

Airspeed

Answer 3

The speed of the wind when compared to the ground speed. V(wind) - V(ground)

Question 4

Airspeed

Answer 4

The speed of the wind when compared to the ground speed. V(wind) - V(ground)

Question 5

Coanda Effect

Answer 5

Air follows shape of curve

Question 6

Relative Wind

Answer 6

Wind speed + direction

Question 7

Coreolis Effect

Answer 7

Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere

Question 8

Spheres of air least to highest levels above ground

Answer 8

Troposphere, Stratosphere, Mesosphere

Question 9

Flaps

Answer 9

Trailing edge, increase area & lift

Question 10

Slats

Answer 10

Leading edge, increase area and lift

Question 11

Slats

Answer 11

Leading edge, increase area and lift

Question 12

LIFT GENERATION FORMULA

Answer 12

force of lift = lift coefficient times density & velocity squared divided by two, multiples by surface area
