Aviation equipment: development, production, service

Mankind is constantly striving to improve the conditions of existence. Progress in various spheres constantly leads to an increase in the standard of living. It is enough to compare the life of some 150 years ago with the present to understand: progress is irreversible and very good.

One of the factors accelerating progress is the improvement of vehicles, the invention of new species. A couple of centuries ago, few believed in the ability to move through the air in aircraft heavier than air. Today, aviation has firmly entered the life of man. Aviation equipment is used in many areas of life: freight and passenger transportation, agriculture, scientific research, military industry and even recreation.

The origin of aviation

At the dawn of progress in this field, it was driven mainly by enthusiasts, inspired by the idea. At that time, there was little knowledge about the laws of aerodynamics, therefore, specimens with waving wings were built. The technology of materials was also far from perfect, so the first flying machines were very unreliable. Thanks to the cinematography, which enabled the accelerated shooting of the wings of birds, bright minds abandoned moving wings. Studies and experiments in the field of aerodynamics began. This was one of the first steps that gave a push in the right direction.

The then aircraft designers realized that the development of aviation equipment would be more successful if the models of future aircraft were used, to study the results of their blowing in wind tunnels. Thus, the method of scientific poking became much cheaper and safer.

It also became apparent that it is impossible to develop a sufficiently reliable aircraft alone. Too much heterogeneous information had to be taken into account in order to create truly reliable aviation equipment.

Difficulties at the initial stage of development

Another factor that constrained progress was that the designer himself had to perform many additional duties. It was necessary not only to make calculations, but also to design and maintain aircrafts still at the development stage and in the future, independently to test the aircraft, which means - it was necessary to learn how to fly. Who? At himself.

And another important factor - it was necessary to earn money to provide and their living, and the promotion of their dreams. In addition, often had to overcome the ridicule and jeers of envious persons, ill-wishers and skeptics. And this lay down a heavy emotional burden on the inventors.

Design offices

Today, when this difficult stage in the formation of the aviation sphere has long been over, we have a clear division. There are design bureaus that receive orders from interested departments to develop aviation technology. These developments are generously financed by the customer's side, whether by the state or some other body. Design offices have all the necessary material resources for research, calculations, modeling, prototype production.

From calculations to tests

When a specific instance of the aircraft is ready, it's time to test the aircraft. The case is attended by trained personnel - test pilots and other flight crews, who have years of experience flying in various weather conditions and extraordinary situations, when the failure of any unit occurs.

First, aviation equipment is tested on the ground. All operating parameters are recorded by an airborne recorder and analyzed. If all parameters are within acceptable limits, the next, most crucial step is the flight tests. At this stage, in addition to airborne recorders, much attention is paid to the impressions and sensations that arise in the testers during trial flights. On their basis, measures can be taken to refine the areas in which comments or suggestions will be made.

Experimental samples are not the end of the process

After all this is taken into account in the design, it is time to adjust the production of aviation equipment that has been tested. The order arrives at the aircraft factory, which has the necessary equipment to carry out the order. However, not one plant will participate in the manufacture of aircraft. Dozens of factories with a narrow specialization can participate. For example, manufacturing aircraft engines, navigation equipment, devices for monitoring the operation of all possible systems in flight. Thousands of parts must be prepared and tested for compliance with the calculated parameters. This is a very important moment.

For example, when manufacturing blades for turbines of jet engines only 3-5% of the manufactured parts will pass technical control. The rest will be rejected and sent for remelting. The quality of the product is subject to maximum requirements. After all, the failure of important details can lead to disastrous consequences.

The things for which they worked

But here our handsome man descends from the assembly line. Years of painstaking work should pay off. On one copy, no one will stop. Dozens will be produced, and maybe hundreds of copies of the aircraft.

The exploitation of aviation equipment will bear fruit. Now is the time to engage in this process well-trained flight crews, ground personnel, who will provide aviation equipment at many airports, airports, radar surveillance and navigation stations.

The sky begins with the earth

Of course, the personnel who will be responsible for servicing aviation equipment on the ground will not be left out.

Refueling with fuel, oil, compressed air, water ... Preflight and post-flight inspection of equipment to identify possible malfunctions ... Replacement and testing of units and assemblies that have served their useful life for possible future operation ... Regular external inspection of the fuselage, wing, chassis, engines, tail. .. All this requires training and training of highly qualified personnel.

For some 150 years, aviation has moved from the category of fantasy and dreams into a high-tech industry. In this area, millions of people are employed. The time has long come to an end when aviation held on to one enthusiasm. Today it is the sphere of scientific research, development, testing and production, which brings tremendous benefits to humanity.

If we compare the appearance of modern aircraft with the first samples, we will see grace and beauty, reliability and comfort. For the benefit of people are working such newly emerged types of science as biomimetics and ergonomics. Despite the tremendous success, aviation technology continues to develop. There is no doubt that it will remain the subject of further improvement and pride of mankind.
