Modern people are accustomed to the possibility of being in a few hours to the opposite point of the globe by plane. Few people think about how complicated the process of creating an aircraft is.
Instructions
Step 1
The development of a new aircraft begins in the design office, where a list of technical operating conditions and tasks that the aircraft must solve is drawn up. Based on these data, an optimal solution is found for the appearance of the aircraft, its classification and engine type.
Step 2
Based on the tasks set for the range and speed of flight, the number of passengers or the weight of the transported cargo, designers develop an engine or use existing samples. At the moment, the most popular propulsion systems for mass transportation are turbojet engines. They satisfy to the greatest extent one more significant parameter - efficiency.
Step 3
The next stage is the creation of drawings, according to which layouts are built. At the same time, a special division of the design bureau selects materials with the required margin of safety. Recently, there has been a tendency to switch from aluminum alloys to composite materials.
Step 4
Then the draft design is transferred to the design one, according to which prototypes of the future aircraft are created. They go through many tests that simulate real-life situations. All structural units are checked for resistance to static loads, such as temperature, humidity, and counter-flow force. In addition, lengthy joint fatigue tests are carried out. Development of prototypes can take up to several years before the aircraft goes into serial production. This explains the high cost of aircraft.
Step 5
In various workshops of the aircraft plant, parts of the aircraft body, engine, control systems, electrical and radio equipment are manufactured, after which the aircraft is assembled, tested and sent to the customer. Foreign manufacturers often follow the path of diversifying production, distributing it to various factories, which allows accelerating the construction of serial samples.
