The Essential Parts of the Aircraft.

1. The development of science and technology brought about the appearance of different types of the aeroplanes. The aeroplane of today differs greatly from the craft of many years ago. As a result of progress in science and technology it now develops high speed and has long range. Any airplane structure may be divided into five main sections: fuselage, wing, power plant, landing gear and tail unit. Each section has its own function.

2. The wings are light structures of all-metal construction which extend on each side of the fuselage of the aeroplane. The function of the wing is to provide necessary lift and support of the aeroplane in flight. They may also house engines, fuel tanks and landing gear while in flight.

3. The fuselage is the central body of the aeroplane. It houses the crew, passengers, equipment, controls and cargo. The fuselage may also contain the engine, fuel and oil tanks. It carries the landing gear and the tail unit. Fuselages of modern aeroplanes are also of all-metal construction.

4. The landing gear is one of the essential parts of the aeroplane. It supports the aeroplane on the ground and water. Thus there are different types of landing gear. Besides the landing gear structure has to reduce shocks of landing.

5. The power plant is the most essential unit of the aeroplane. It serves for developing power for flight and creating thrust.

6. In the rear of the aeroplane there is a tail unit. It consists of fixed vertical and horizontal stabilizers with movable rudder and elevator attached respectively to them.

II. Найдите в тексте ответы на следующие вопросы:

1. What is the most essential unit of the aeroplane?

2. What does the tail unit consist of?

III. Найдите в тексте производные от следующих слов, выпишите их, переведите на русский язык, укажите часть речи:

To develop, to appear, great, to land, to differ, to construct, to equip, essential, to move.

IV. Перепишите и переведите на русский язык следующие предложения. Подчеркните инфинитив и определите его функцию:

1. It was necessary to develop power plant without propellers in order to drive airplanes at sonic and supersonic speeds.

2. New methods to be used in testing the engine will be very effective.

3. To fly the aircraft safely under icing conditions the leading edges of the wing, tail unit and engine air intakes are heated with hot air.

4. In an effort to find some new sources of power the scientists turned to rocket principle.

V. Перепишите и переведите на русский язык следующие предложения, подчеркните причастия I и II и определите их функции:

1. Air loads are transferred from the skin to the ribs and then to the spars.

2. Constructing the main supporting and lifting surfaces the wings must have good streamlined shape and be of a strong design.

3. The raised elevators cause the airplane to produce the climb.

4. The cockpit is isolated from the other cabin with a pressure bulkhead, thus preventing the cabin decompression in case of emergency drop of cockpit pressure.

VI. Перепишите и переведите следующие предложения на русский язык, подчеркните герундий:

1. Spars serve for carrying all air loads acting on the wing in flight.

2. The power plant is a means of creating thrust necessary for the movement of the airplane through the air.

3. The airfoils designed to control the airplanes in flight by changing their attitude about various axes are known as flight control surfaces.

4. Cooling the aircraft engine may be effected either by air or by liquid.

VII. Перепишите и переведите следующие предложения с конструкцией It is (was)…that (who, which)…..

1. It was Popov who invented the radio.

2. It is from the cockpit that all controls used in flying and landing radiate.

3. It was in war time that the helicopter served in many rescue operations.
