AVIT 323 Block 9 Exam Question with
Correct Solutions.
Planform - ANSWERSThe shape and layout of the fuselage and wing of a fixed wing
aircraft
Adverse Pressure Gradient - ANSWERSThe rate of rise in pressure from the low-
pressure peak on the airfoil to the atmospheric pressure aft of the trailing edge
What is Bernoulli's principle? - ANSWERSIt states that an increase in velocity of a
stream of fluid results in a decrease in pressure
What is the Magnus effect? - ANSWERSThe actual upward force that results from low
pressure on an airfoil
Newton's first law of motion - ANSWERSAn object at rest stays at rest and an object in
motion stays in motion unless acted upon by an outside force
Newton's second law of motion - ANSWERSif a force acts on a body, the body will
accelerate in directional of force
Newton's third law of motion - ANSWERSfor every action there is an equal and opposite
reaction
What are the different types of flaps? - ANSWERS- plain
- split
- slotted
- fowler
- slotted fowler
Plain Flaps - ANSWERSthe rear portion of the wing airfoil rotates downwards on a
simple hinge arrangement mounted at the front of the flap
Split flaps - ANSWERSthe rear portion of the lower surface of the wing airfoil hinges
downwards from the leading edge of the flap, while the upper surface remains immobile
Slotted flaps - ANSWERSsimilar to the plain flap but incorporates a gap between the
flap and the wing to force high pressure air from below the wing over the upper surface
of the flap
Fowler flaps - ANSWERSa split flap that slides rearwards level for a distance prior to
hinging downwards (increases chord & surface area, then increases camber)
