Exercise 12. Fill in the blanks.

I. The flaps are hinged to … … of the wing. 2. The slotted flap provides a slot between the wing and … … of the flap. 3. The airplane must have enough ... to support its weight. 4. When the flaps are lowered ... of the wing is increased 5. The split flap creates more ... than the plain flap. 6. In the split flap the shape of… … of the wing is unchanged.

(the leading edge, the trailing edge, lift, drag, the camber, the upper surface).

Exercise 13. Translate from English into Ukrainian.

I. The flaps are located between ailerons and the fuselage. 2. The flaps permit landing on short fields. 3. The Fowler flap moves backward on a track. 4 It is dangerous for the- plane to increase the angle of attack too much. 5. By changing the attitude of the wing we may increase the lift. 6. We can considerably increase the drag deflecting the flap downward.

Exercise 14. Translate the following sentences.

1. Закрилки - це допоміжні, поверхні крила. 2. Закрилки використовуються при зльоті та посадці 3. Підйомну силу можна збільшити, збільшуючи швидкість, змінюючи положення крила, збільшенням кривизни крила. 4. Ми можемо класифікувати закрилки відповідно до їх механічної природи.

Exercise 15. Put the questions to the sentences. Begin them with the given question-words.

1. Extension of the flaps increases the effective wing area.(What area ... ?)

2. Take-off flap positions provide high lift and relatively low drag.(What ... ?)

3. Landing flaps produce high lift and high drag. (What flaps ...?)

4. When airspeed is reduced the flaps automatically return to the fully extended position. (When ... ?)

5. Minor damage to a flap lower surface does not require flap replacement (Does .. ?)

Exercise 16. Name the aviation terms and translate the sentences.

1. When the angle of attack is so steep that the airflow over the upper surface of the wing breaks, lift is lost and drag is increased. 2. Cantilever wing is a wing supported only where it is attached to the fuselage, without other supports or braces. 3. Pilots avoid too high an angle of attack which may result in a loss of lift. 4. Trim tabs free the pilot from constantly adjusting the controls in flight. 5. In take off and approach to landing flaps supply greater lift and drag correspondingly. 6. The tips are made of composites with an aluminum leading edge for erosion protection.
