ANALYSIS OF STANDARDS REQUIREMENTS FOR AIRCRAFT BONDING

Abstract

In the design, modernization and further aircraft operation, the issue of bonding as a means of electromagnetic interference control from equipment and static electricity, lightning protection is given much attention.
 The relevance of this article lies in the need to understand and comply with the requirements of the standards of all parts of the research and production cycle of modernization of aircraft from enterprises that develop devices and equipment for aircraft to the design bureaus of aircraft repair plants.
 To ensure the normal operation of radio technical apparatus on aircraft, protection against interference is applied, that caused by electrostatic charges due to voltage ripples on the generator commutator and engine manifold or at the output of rectifiers, as well as due to magnetic fields generated by various electrical facilities and wires.
 Interference protection of aircraft onboard equipment from electromagnetic interference is achieved by carrying out special measures, including screening of conductors, harnesses of the aircraft electrical system and ignition system of power drive units, bonding of shielding coatings of conductors and harnesses, structural elements and aircraft units. Bonding is also carried out to protect against lightning strikes.
 The article analyzes the requirements of state and industry standards for bonding, as the main technical measure of lightning protection and electromagnetic interference control on aircraft. Careful selection of the requirements of the standards allows to properly conduct and control the bonding of aircraft. It helps to determine the division of responsibilities in the design, execution and control of the state of bonding.
