Aerodynamics Vocabulary Flashcards
A tube with a narrow part to increase the velocity and decrease the pressure of a fluid.
Venturi
Force = Mass X Acceleration (F=MA).
Newton’s Second Law of Motion
The flow of air around an object caused by the movement of either the air, the object, or both the air and the object.
Relative Wind
Any part of the aircraft that converts air resistance into a force useful for flight.
Airfoil
The angle created by the chord line of the wing and the direction of the relative wind.
Angle of Attack
Gravity Lift Thrust and Drag.
Aerodynamic Forces
The “law of inertia.”
Newton’s First Law of Motion
An imaginary line from the leading edge to the trailing edge of a wing.
Chord Line
The ratio of the amount of water vapor actually present in the atmosphere compared to the amount that would be present if the air were saturated at the prevailing temperature and pressure.
Relative Humidity
This demonstrates that when the velocity of a fluid increases, its pressure decreases.
Bernoulli’s Principle
“For every action there is an equal and opposite reaction.”
Newton’s Third Law of Motion
Wingspan compared to chord.
Aspect Ratio
The curvature of a wing from leading edge to trailing edge, in which an increase creates more lift proportionately.
Camber
The angle created by the chord line and the longitudinal axis of the aircraft.
Angle of Incidence
The actual amount of water vapor present in a mixture of air and water.
Absolute Humidity
