Avionics

 

Avionics to denote the entire complex electronic equipment, which is installed on board the aircraft. Very often, in parallel with the word "Avionics" is abbreviated as avionics, which stands for avionics. The basic elements of electronic equipment are navigation, communications and management. With regard to the control equipment, it is a very large number of systems, ranging from the searchlight to modern radars.

The domestic aviation experts are divided on the power plant and aircraft. Accordingly, one engaged in the aviation system and others - avionics.

Russian Air Force has a clear division of airborne avionics equipment and aircraft equipment. Avionics created for emission or reception of radio waves. With regard to aircraft equipment, this equipment, machinery, parts, which in its work uses an electric current, but no radio. Also military aircraft can be equipped with electronic weapons, but they are a separate piece of equipment.

In the domestic aircraft industry notion of "Avionics" is almost never used because the designation is considered to be the avionics - avionics - and as - aircraft equipment.

The history of the avionics

The concept of "Avionics" began to be used in Western countries to 1970 years. It was at this time Electronics reached a high technical level, which allowed the use of electronic systems on board the aircraft. During these years, we created the first on-board computers for aircraft. In addition, we have begun to use a large number of automatic control systems.

Initially, avionics and electronic equipment for automation began to order the military to carry out a large range of military tasks, and improve the accuracy of the performance of combat missions. As a result, fighting vehicles have become so dependent on the avionics that the flights were carried out depending on the selected mode of electronic control. Due to improvement of aircraft avionics is also not lagging behind in development. In today's time-board equipment occupies a large part of the material costs for the manufacture of aircraft. For example, in the manufacture of aircraft such as F-14 20% the total value of all allocated to aircraft avionics. Such systems are widely used in civil aviation, which allows you to automate and simplify the machine control.

Modern composition avionics

Equipment for the control of the aircraft:

  • Navigation system.
  • Display System.
  • The communication system.
  • The system, flight control, such as FCS.
  • The system is responsible for preventing collisions in the air, such as TCAS.
  • The total control system.
  • Equipment meteorological observations.
  • Equipment for registration of all flight parameters. This flight recorders and controls.

Equipment for weapon control:

  • Sonar.
  • Electron-optical equipment.
  • Radars.
  • Systems for finding and fixing purposes.
  • Equipment for weapons control.
