Flight

Question 1

What are the four forces of flight?

Answer 1

Lift thrust drag and gravity

Question 2

True or false: Thrust and Drag work in opposite directions.

Answer 2

True

Question 3

What is lift

Answer 3

Lift is the force that pushes the aircraft upward, while “Deflected Downwash” causes the wing to be deflected upward. Newton’s Third Law states that for every action there is an equal and opposite reaction.

Question 4

How is weight different from mass?

Answer 4

Your mass is the same no matter where you go in the universe; your weight, on the other hand, changes from place to place.

Question 5

True or False: Gravity and Lift work in opposite directions

Answer 5

True

Question 6

Multiple Choice
What are the 3 axes
a) Yaw Pitch Gravity
b) Pitch Roll Yaw
c) Roll Lift Yaw

Answer 6

B

Question 7

How do you reduce drag?

Answer 7

making the airplane more streamlined, the wings narrower, or by using new materials that make the surface more smooth

Question 8

What causes 80% of lift
a) Bernoulli’s Principle
b) Deflected Downwash

Answer 8

B

Question 9

Explain Bernoulli’s principle

Answer 9

Air moving over the curved upper surface of the wing will travel faster and thus produce less pressure than the slower air moving across the flatter underside of the wing
( faster the fluid goes lower the pressure and the slower the fluid goes higher the pressure)

Question 10

how do planes wings work? (lift)

Answer 10

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.

Question 11

Explain defelcted downwash

Answer 11

Deflected downwash is when air hits the bottom of the wing and pushes the wing up because of Newton’s 3rd Law

Question 12

What are the 3 main flight controls?

Answer 12

The ailerons, elevator (or stabilator), and rudder

Question 13

What are the 3 main movements of bird flight

Answer 13

Powerstroke, Backstroke, and Glide

Question 14

Multiple choice: What is Newton’s Third Law

A) for every action there is an equal opposite reaction
b) faster moving air goes over the wing and slower moving air goes under
C) idk what to put here

Answer 14

A

Question 15

What is drag

Answer 15

Drag is the force that resists movement of an aircraft through the air.

Question 16

what is thrust

Answer 16

thrust is what allows the plane to move forward

Question 17

What controlles Yaw Pitch and Roll

Answer 17

The rudder controlles Yaw
The elevators control Pitch
The ailerons control Roll

Question 18

What are VTOL and STOL

Answer 18

VTOL = vertical take off and landing STOL = short take off and landing

Question 19

LONG ANSWER: How does a jet engine work?

Answer 19

Jet engines, which are also called gas turbines, work by sucking air into the front of the engine using a fan. From there, the engine compresses the air, mixes fuel with it, ignites the fuel/air mixture, and shoots it out the back of the engine, creating thrust.
