Text 2. Main Units of Aircraft

Airplanes usually have the same basic configuration. Any airplane consists of five principal structural units: the fuselage, the wing, the tail unit, the landing gear and the power plant.

The fuselage is the main structure or the central body of the aircraft and its largest element extending from the nose to the tail of the machine. It provides space for flight crew, passengers, cargo, controls and most of the accessories.

The fuselage has a cockpit section at the front end, where the crew control the airplane and passenger and cargo compartments. The wings, stabilizers and the landing gear are attached to it, and the engine in some designs.

The wing is one of the large flat parts that stick out from the sides of airplane and help to keep it in the air. They are the main planes. The wing extends equally on each side of the fuselage. Wings develop the major portion of the lift of a heavier-than-air aircraft. Wing structures carry some of the heavier loads found in the aircraft structure. The wings are lifting and supporting surfaces of the airplane in flight. So the aircraft uses the aerodynamic lift of the wing and the power plant thrust. The particular design of a wing depends on the size, weight, speed, rate of climb and use of the aircraft.

The tail unit is the back part of an airplane. It is also known as the tail assembly or empennage. All three terms may be used interchangeably. The tail assembly is attached to the rear of the fuselage and consists of vertical and horizontal stabilizers, a rudder and elevators. It gives stability to aircraft and provides control in flight.

The landing gear or undercarriage in aviation, is the structure that supports an aircraft on the ground and reduces shocks of landing, that is, it absorbs the forces imposed on the aircraft by take-offs and landings, so it allows the aircraft to taxi, take off and land.

The power plant is a source of power. It provides power for flight and propels the airplane. The power plant contains an engine or engines and some systems.

Exercise 42. Read, translate and give the gist of text 3.
Text 3. Aircraft Performance

The aircraft performance includes dimensional data and the main flying characteristics.

Dimensional data are length, wing span, height and width. The main flying characteristics are maximum take-off weight, maximum landing and payload weight, seating capacity or number of seats, number of crew, cargo capacity, cruising speed, flight range, flight altitude, non-stop flying time, practical ceiling or service ceiling, engine type and thrust of each engine, number of engines, take-off and landing ground run, maximum fuel capacity, etc.

The aircraft usually takes the name of the designer or manufacturer. Here are some of aircraft designers: Antonov, Ilushin, Tupolev, Yakovlev. Manufacturer’s names are represented by: Boeing, Bristol, Canadair, Convair, Douglas, Lockheed, Vickers and others. Following the name of the designer or manufacturer comes a type code, known in some airlines as a class. For example: Antonov-70 (designer’s name and type code), Douglas DC-6B (manufacturer’s name and type code).

Aircraft can be supplied in some versions: Economy Class, Business Class, Tourist Class, First Class, Second Class, Third Class.
Exercise 43. Answer the questions on text 3.

Text 4

William E. Boeing was a wealthy, 34-year-old man when he had his first flying lesson in 1915. He immediately decided that he could build a better airplane. With his friend Conrad Westervelt, a Navy officer, he began working on his first biplane on the shores of Seattle’s Lake Union. A year later, on July 15, 1916, Mr. Boeing incorporated the Pacific Aero Products Company. In 1917, the name was changed to the Boeing Airplane Company. Boeing and Westervelt called it the B&W, after their initials. Boeing was the first person to fly it.

A wood, wire, and cloth seaplane, the B&W, could carry the pilot and one passenger and cruise at 67 mph (108 km/h). The first flight was on June 29, 1916, just 12 1/2 years after the Wright brothers first flew at Kitty Hawk.
