Nikolay E. Zhukovsky, an outstanding scientist, the creator of Russian aviation, was born on January 17.
On this occasion we present a selection of new aviation standards, which came into force for the first time in January 2021.
GOST R 59005-2020, Aviation technology. Research laboratory complex for aircraft robustness. General requirements.
In the laboratory complex, which is covered by this document, the tests related to the service life, aeroelasticity, static and dynamic strength of landing devices are performed. These tests solve the tasks aimed at drawing conclusions on the airworthiness of aircraft.
Such a complex must have, among other things, laboratories in which the following are tested: fatigue, survivability, static strength and stability of aircraft structure elements.
Laboratories must be equipped with a power floor, ceiling and columns; air conditioning, ventilation, lighting, heating water, air and power supply systems; as well as collapsible portals and an oil pumping station.
GOST R 59002-2020, Aircraft equipment identification and traceability. Basic provisions.
According to the document, unique identification and machine-readable marking of civil aircraft is used to control their authenticity and counteract trafficking of counterfeit aviation products.
At the same time identification is necessary to control current configuration of on-board equipment, traceability of products from production to utilization and automation of logistic operations in supply chains.
Preferred locations for radio frequency tagging are numbered aircraft components that ensure airworthiness or require effective traceability measures for delivery, storage, operation and repair.
Printed circuit boards, electromechanical and electro-radio assemblies that require instant, error-free and non-contact recognition are also frequently tagged.
GOST R 58995-2020, Aircrafts. Tests to determine the concentration of toxic products contained in the air space for the crew and passengers.
Air quality tests are conducted on serviceable aircraft, and on vessels in which failure or damage to ventilation, heating, supercharging and other equipment is simulated.
During ground tests, air samples are taken to assess background contamination in the cabins when the engines are off and when the doors, hatches, and blisters of the vessel are closed.
When the engines are on and the ventilation, heating and supercharging systems are operating as normal, air sampling is carried out at the head level of the person sitting in the seat.
In flight tests the carbon dioxide level is checked before the flight.
According to the standard, the air samples taken must be analyzed in a strict sequence.
Gas chromatographic analysis is carried out first, which reveals the content of organic impurities, carbon monoxides and carbon dioxide. Then the presence of nitrogen oxides is checked.
Also in January 2021 came into force:
