RESOURCE
●● What is the difference between mean camber line and the chord line?
Answer: Mean camber: Divides an airfoil section in half between then
upper and lower cambers
Chord line: A straight line from the leading edge to the trailing edge
●● What are the two characteristics of a laminar flow boundary layer?
Answer: - Good for high speeds
- Leaves the wing surface at low speeds
●● Calculate the potential energy of an Archer weighing 2,500lbs if it is
0.5ft above the ground
Answer: 1250lbs
●● Law of Conservation of Energy
Answer: Energy cannot be created or destroyed
●● The amount of yawing moment that the rudder can generate is
affected by which two factors?
,Answer: Aerodynamic force / Distance from C.G. to rudder
●● A 100lb. weight is dropped from a height of 20ft. What is the Ep
before it is dropped?
Answer: 2,000ft/lbs
●● What is the KE of the same weight at the moment of impact after
falling 20 feet?
Answer: 2,000ft/lbs
●● In order to increase CL, high lift devices...
Answer: Any of these answers
●● AOA is measured between the
Answer: Chord line and relative wind
●● Vortex generators increase lift by
Answer: adding kinetic energy to the boundary layer
●● An increase in air density affects the air density by
Answer: Decreasing
, ●● Slots increase energy in the boundary layer by allowing air from
below the wing to slip through the wing during high AOA flight
Answer: True
●● Fowler flaps increase a wings
Answer: camber and surface area
●● The momentum change theory of lift production states that by
accelerating airflow downward, lift is created. This is explained by...
Answer: Newton
●● The earth's atmosphere contains a constant amount of nitrogen,
oxygen, and other gases but increases in density with an increase in
altitude
Answer: False
●● The standard atmospheric values are
Answer: - 15 degrees Celsius
- 59 degrees Fahrenheit
- 29.92"
●● Which best describes now lift is created?
Answer: Newton and Bernoulli's theories together
