  1. AIRPLANEs The most beautiful dream that has haunted the heart of man since Icarus is today reality.— Louis Bleriot

  2. HISTORY OF AIRPLANES Ever since man first saw a bird fly, man has wanted to fly. The first attempts were efforts to fly like a bird by attaching feathers to their arms and flapping. Those attempts were unsuccessful.

  3. First Airplanes The first airplane that was flown was a glider. A glider is a non-motorized flying machine (and very hard to control). Early gliders were launched from high places like cliffs and floated on the wind to the ground.

  4. A man named Sir George Cayce made the first glider that actually flew. His first glider didn’t have passengers or a pilot. It was too small and could not fit anyone in it.

  5. In 1899, the Wright Brothers designed their first aircraft: a small, biplane glider flown as a kite to test their solution for controlling the craft by wing warping. Wing warping is a method of arching the wingtips slightly to control the aircraft's rolling motion and balance.

  6. They believed that they could use this technique to obtain roll control by warping, or changing the shape, of a portion of the wing. The Wrights spent a great deal of time observing birds in flight. They noticed that birds change the shape of their wings to turn and maneuver.

  7. We owe our thanks to these two geniuses!

  8. Development in time On Dec. 17, 1903, Orville and Wilbur Wright flew the first piloted airplane off the beach near Kitty Hawk.

  9. N. C. Henri Blériotand Glenn H. Curtiss made significant improvements in airplane design and, as more powerful engines became available, flew successively longer distances. In 1909 Blériotflew across the English Channel; In 1939 the first transatlantic service carrying both mail and passengers was inaugurated.

  10. VOCABULARYComponents of a plan: • Wing • Fuselaje • Ailerons • Rudder • Elevator • Flaps • Landing gear • Propeller • Engine compartment • Empennage • Propulsion system • Plan direction • Vouchers • Aerodynamic braks • Compensating

  11. Characteristics of aircraft compared with other means of transport: • More convenient • Faster • Safer • More elegant • Comfortable • More expensive • Sometimes dangerous

  13. Exercise IComplete the text using the words given in the image.What Are The Different Parts Of An Airplane?Airplanes come in many shapes and sizes, but they all have similar parts.  Look at the next picture to see what they are!

  14. The body of the airplane is called the … .  This includes the cockpit, where the pilot sits during the flight. Airplanes have … to lift them up into the sky.  On the rear side of each wing is a part that moves up and down called an ….  Ailerons help the airplane turn right or left.  … help the airplane fly slowly for landing. The tail that sticks straight up like a shark's fin has a part called the… . The rudder helps turn the nose of the airplane right or left. The flat part of the tail has a part called the ….  The elevator makes the airplane's nose move up or down. Since the wings on an airplane don't move up and down like a bird's wings do, something has to make the airplane go forward.  That's where the … and the … come in.  The engine turns the propeller and the propeller pulls (or in some cases pushes) the airplane through the sky!

  15. Exercise IIMach the force with its definitionThe Four Basic Forces of FlightThere are four forces that affect an airplane in flight:  Lift, Gravity, Thrust and Drag. • DRAG • GRAVITY • THRUST • LIFT is the force that keeps all objects on earth.  If we pick up a ball and let it go, it will drop quickly to the ground because of gravity. is a force that an airplane must create to overcome the force of gravity.   An airplane does this by making lift with its wings as the airplane moves forward.   An airplane's forward movement is produced by … .  Which is created by the engine and the rotating propeller.  Just as lift overcomes the force of gravity during flight, thrust must overcome the force known as …, which resists movement of an object — in this case, our airplane!

  16. SurveyOut of 16 people 1.Have you ever flown on an airplane? • Yes -6 • No -10

  17. 2.Are you afraid of flying? • Yes -0 • No- 15 • I don’t know -1

  18. 3.If yes, why?No one answered 4.Why do you think people are afraid of flying? • Heights • Flying doesn’t represent human nature • Due to lack of control, excessive promotion of accidents • Fear of death • Because it’s dangerous • Don’t know

  19. 5.Why would you choose a plane as a means of transport? • It’s faster • Safer [than a car] • For its comfort • It’s relaxing

  20. 6.Do you think traveling by plane is safe? • Yes -9 • No -5 • With some companies -2

  21. 7.If you were to fly on an airplane you would feel safer if you chose: • A Romanian airplane company (e.g. TAROM) -3 • A company from abroad (e.g. KLM etc.) -5 • Any airplane company -8

  22. 8.Do you know who invented the first airplane? • Yes -5 • No -10 • I used to know -1

  23. 9.What is his/hers/their name? • 4 people answered correctly • 1 answered “Vuia” • 11 did not know 10.Do you think traveling on an airplane is popular among the Romanian people nowadays? ( known and used) • 6 people answered that they agree with the fact that traveling on an airplane is popular among the Romanian people • 4 answered that they disagree • 2 persons said that flying by plane is known in Romania, but not used because it is expensive.
