NIFE AERODYNAMICS UPDATED
ACTUAL Questions and CORRECT
Answers
define vector - CORRECT ANSWER✔✔- represents magnitude and direction
define air density - CORRECT ANSWER✔✔- the amount of air mass per unit volume
define moment - CORRECT ANSWER✔✔- a vector quantity of a force applied
perpendicularly over a distance
state the requirements for an airplane to be in equilibrium flight - CORRECT ANSWER✔✔-
the sum of all forces and moments around the center of gravity equals zero
state the requirements for an airplane to be in trimmed flight - CORRECT ANSWER✔✔- the
sum of all moments are equal to zero
describe the relationship between temperature and altitude - CORRECT ANSWER✔✔- as
altitude increases, temperature decreases
describe the relationship between humidity and air density - CORRECT ANSWER✔✔- as
humidity increases, density decreases
state the general gas law - CORRECT ANSWER✔✔- P=pRT (pressure =
density*constant*temperature)
define steady airflow - CORRECT ANSWER✔✔- airflow with constant pressure, density,
temperature, and velocity
explain the continuity equation - CORRECT ANSWER✔✔-
area1*velocity1=area2*velocity2
, explain Bernoulli's Equation, given dynamic pressure, static pressure, and total pressure -
CORRECT ANSWER✔✔- total pressure = static pressure + dynamic pressure
(1/2*density*velocity^2)
explain the different types of airspeeds - CORRECT ANSWER✔✔- indicated (IAS) -
velocity from the cockpit
calibrated (CAS) - IAS corrected for instrument error
equivalent (EAS) - CAS corrected for compressibility
true (TAS) - EAS corrected for density
ground (GS) - TAS corrected for wind
define mean camber line - CORRECT ANSWER✔✔- the halfway point between the upper
and lower surface of an airfoil
define chord - CORRECT ANSWER✔✔- the distance of a line straight through from the
leading to trailing edge
define camber and camber types - CORRECT ANSWER✔✔- the max distance between
MCL and chordline.
positive - produces lift at 0 AOA
symmetric - produces no lift at 0 AOA
negative - produces negative lift at 0 AOA
define wingspan - CORRECT ANSWER✔✔- the distance from wingtip to wingtip
define wing area - CORRECT ANSWER✔✔- the surface area from wingtip to wingtip
including the fuselage
define chordwise airflow - CORRECT ANSWER✔✔- flow from leading edge to trailing
edge
define spanwise airflow - CORRECT ANSWER✔✔- flow from wing root to wingtip
