Chapter 7 Basic Aeronautics and Aerodynamics
Aeronautics - correct answer Movement of objects through the atmosphere
Aerodynamics - correct answer Science relating to the energy of gases in motion
Pressure - correct answer Decreases with an increase in altitude
Temperature - correct answer Measure of how much energy the gas has
Density - correct answer The measure of how many molecules are squeezed into a
defined space
Viscosity - correct answer Resistance to the flow of a liquid or gas
Laminar or turbulent flow - correct answer The smooth or rough flow of air over an
object
Mach number - correct answer The ratio of the speed of an object to the speed of sound
in air
The part of the airfoil that meets the air first is the - correct answer Leading edge
The area determining the airfoils thickness and thus it's lift is the - correct answer
Camber (curvature)
The ______ is the rear junction where the upper and lower parts of the airfoil meet. -
correct answer Trailing edge
The ______ is the imaginary part of the airfoil that is the starting point for designing an
airfoil in cross-section. - correct answer Chord (chord-line)
Ideally, when a plane is in smooth flight, the force of the total lift equals the force of the
total _____ and the force of _____ equals the force of drag. - correct answer Weight,
thrust
Lift and weight are in opposition to each other. Induced lift can be increased by
changing the _____ of the ______. - correct answer Camber, airfoil
A _____ occurs when lift is destroyed and the force of weight takes over. - correct
answer Stall
The sudden displacement of air and the resulting wedge-shape wave is called a
______. - correct answer Shock wave
