These flexible duct element blanks are manufactured from advanced non-metallic composite materials and are designed specifically for air conditioning and environmental control systems (ECS) in aircraft. Developed and produced entirely in-house by VIAM — the All-Russian Scientific Research Institute of Aviation Materials, a State Scientific Center of the Russian Federation operating under the National Research Center "Kurchatov Institute" — they represent the output of one of Russia's oldest and most authoritative aerospace materials institutions, with a research heritage spanning over 90 years.
The blanks feature a uniform white-coated surface whose coverage quality and texture are assessed against a certified reference sample, ensuring visual and dimensional consistency across production batches. They are manufactured to meet stringent aviation hermeticity requirements per OST 1 00128 (group 2-12), with a maximum allowable leak rate of 6.6 × 10² Pa·l/s.
The mass of the spiral portion of the duct does not exceed 16 g per 100 cm² of surface area, reflecting the weight discipline demanded by aerospace design. Production is governed by technical specification ТУ 1-595-УНТЦ-1724-2018.
The non-metallic composite construction delivers inherent corrosion resistance and the structural flexibility needed to absorb assembly tolerances and in-service vibration loads within aircraft duct networks.
