History of the Boeing 737 Airliner
737 Boeing began to be developed in 1964. The airliner was supposed to impose the struggle against such medium-range airplanes as DC-9. But Boeing was lagging behind in the race: while the Boeing 737 was just being developed, the above-mentioned DC-9 was already being certified. In addition, the picture of the Boeing 737’s successful progress was spoiled by a «political» issue raised by pilots’ unions and other organizations, which insisted that such an airplane should be operated by a crew of three pilots or two pilots and a flight engineer. This was not favorable to the airlines, and the Boeing itself was not designed for three pilots. However, the pilots stood their ground, and the engineers had to redesign the cabin of the airliner.
Boeing 737 Design
The Boeing 737 design is based on the principles of aerodynamics, economy and safety. The airplane fuselage has a round shape, which provides strength and reduces air resistance. The wings are arrow-shaped and equipped with flaps that increase lift and controllability. The wingtips have winglets that reduce inductive drag and fuel consumption. The tailplane consists of vertical and horizontal stabilizers, which provide stability and balance of the aircraft. On the stabilizers there are rudders of altitude and direction, which allow to change the flight path.
737 Boeing airplane is equipped with two turbojet engines, which are located under the wings. The engines have a high thrust coefficient and low noise and emissions. The engines work in synchronization with the flight control system, which controls all flight parameters and ensures passenger safety and comfort. The flight control system consists of computers, sensors, instruments and knobs, which are located in the cockpit. The cockpit is equipped with six color TFT displays that show all necessary flight information¹.
The Boeing 737 aircraft has a spacious and comfortable passenger cabin, which can accommodate from 128 to 230 people depending on the configuration. The cabin has a modern design and is equipped with air conditioning, lighting, entertainment and communication systems. The cabin is divided into several classes of service, which differ in terms of comfort and price. The cabin also has toilets, kitchen, luggage lockers and emergency exits. The cabin meets all safety and hygiene requirements.
