3. Fundamentals Of Flight Flashcards
What are the forces of flight acting on an aircraft?
What is the very front of the wing called?
What is the very back of the wing called?
What is the chord line?
The Leading Edge
The Trailing Edge
The line from the leading edge to the trailing edge connects them.
What is the angle of attack?
The angle between the wing’s chord line and the relative wind is called the angle of attack.
What is Bernoulli’s principle?
Bernoulli’s principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid’s potential energy.
“As the velocity of a fluid (air) increases, its internal pressure decreases.”
How does the wing of a plane create lift?
Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So, the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.
What is the relationship between thrust and lift?
Thrust and lift are related by allowing the plane to go upwards once they are both higher than the forces of gravity and drag
What’s the difference between induced and parasitic drag?
Induced drag- developed as a result of lift production
Parasitic drag –resulting from moving aircraft shape through the air
