2. Transcribe the words:
combustion, turboprop, fuselage, cargo, baggage, axis, empennage, crew, rectangular, chord, stabilizer, rudder, elevator, vertical, structure, dynamics
3. Match the words from the texts (1-5) with their synonyms (A-E):
| transportation | A | airfoil | |
| tail | B | shipment | |
| fuselage | C | fin | |
| stabilizer | D | airframe | |
| wing | E | empennage |
4. Explain in English and then translate the expressions into Russian:
military aircraft, passenger airliners, flight controls, flap, fuselage, rectangular wing, swept wing, empennage, tricycle landing gear
5. Match the words from the texts (1-10) with the definitions (A-J):
| cargo | A | the longitudinal retarding force exerted by air or other fluid surrounding a moving object | |
| fuselage | B | the width of an aerofoil from leading to trailing edge | |
| empennage | C | goods carried on a ship, aircraft, or motor vehicle | |
| drag | D | the main body of an aircraft | |
| chord | E | stabilizing surfaces at the tail of an aircraft | |
| wingtip | F | a vertical aerofoil pivoted from the tailplane of an aircraft to control movement about the vertical axis | |
| rudder | G | the tip of the wing of an aircraft | |
| elevator | H | the undercarriage of an aircraft | |
| landing gear | I | an imaginary line about which a body rotates | |
| axis | J | a hinged flap on the tailplane of an aircraft, used to control the motion of the aircraft about its lateral axis |
6. Find in the texts the English equivalents for the words and expressions:
(1) airfoil, (2) airframe, (3) thrust, (4) end edge, (5)
arrow wing, (6) tail assembly, (7) vertical tail surfaces, (8) horizontal tail surfaces, (9) altitude control, (10) landing device, (11) aileron, (12) engine
7. Answer the following questions. Begin your answers with such introductory phrases as: as far as I know; as far as I remember; to my mind; certainly; it's hard to tell; probably; of course; if I am not mistaken, etc.
1) What common traits do all airplanes share?
2) What is the difference between a rectangular wing and a tapered one?
3) What does the empennage consist from?
4) What is the most common arrangement of the landing gear?
5) What is air from the aeronautics point of view?
