First homework

 This is our first homework of this course. With this activity, we have a first view of the parts of the plane which makes it flies and be airworthy. 

Airplane parts and function

1. Describe the following aircraft motions.

1. Pitch: up and down movement of the plane’s nose/on the horizontal

axis.

2. Roll: The rotation movement of the wing tips of the aircraft

3. Yaw: The side to side movement of the nose. Swaying motion side to

side of the nose of the plane / moving from left to right using the rudder.

4. Loop: A complete roll

5. Dive: Decrease the inclination of the nose / downward motion when

the plane lands.

6. Climb: to go up (movement of plane)

7. Lift: A force which pushes the plane up.

2. What are the functions of the parts of the airplane pictured above?

1. A: Vertical stabilizer: controls the yaw movement, keep the nose of

the plane from swinging from side to side.

2. B: Rudder: directs the tail left or right / changes yaw movement.

3. C: Elevator: changes pitch

4. D: Horizontal stabilizer: controls the pitch movement. (the up and

down movement of the nose)

5. E: Flaps: increase lift and drag

6. F: Aileron: Roll the wing from side to side / change roll

7. G: wings: flat surface which generate lift.

8. H: Turbine engine: generates thrust

9. I: Fuselage: holds everything together

10. J: slats: increase the lift.
4. Which parts are used to control lift at low speed for takeoff and landing?

Slats, Flaps and soilers

5. Which parts, installed one to each wing, operate in opposite directions (i.e., one up and one down)?

The ailerons operate in opposite directions.

6. If the part in Problem 4 on the right wing is up and the one on the left wing is down, what will the airplane do?

The plane will roll right

7. If the pilot lowers the elevator, what will the airplane's tail do?

The tail goes up and the plane will dive.

8. What will this in turn cause the airplane's nose to do?

The nose of the plane will dive

9. If the pilot moves the rudder to the left, what will the airplane's tail do?

The airplane’s tail will turn to the right

10. What will this in turn cause the airplane's nose to do?

The airplane’s nose will turn to the left

11. What motion will occur in an airplane with the elevator deflected up and the rudder deflected to the right?

The airplane will climb and turn to the right.

12. What is a spoiler?

A spoiler is a plate that are used to disrupt the flow over the wing and change the amount of force by decreasing the lift when the spoiler is deployed.
