Russian stealth aircraft skin passes factory testing

Prototypes of a new radar-absorbing layered material used in aircraft have successfully passed required factory testing in Russia, according to Rostec State Corporation.

Prototypes of a new radar-absorbing layered material used in aircraft have successfully passed required factory testing in Russia, according to Rostec State Corporation.

The Russian state-owned company, Rostec State Corporation, announced during a public statement on 30 March that it had created a metal-core glass filament base which can be used in aircraft components.

The material of interconnected glass fabric layers is reportedly capable of absorbing broadband radio waves. The new material also reportedly absorbs up to 95 per cent of incident electromagnetic radiation from radars and considerably hinders aircraft detection using radar equipment.

Central Design Bureau of Radio Materials general director Aleksey Dymovskikh said radar-absorbing material is based on thin glass-insulated, metal-core filaments.

“The modern military aircraft engineering has faced the issue of development of a radar-absorbing structural material long ago,” he said.

The existing types of stealth aircraft coatings require regular restoration, while the lower-reflectivity fibreglass is maintenance-free.

“Our prototypes have already successfully passed the required factory tests,” he said.

The stealth material has been developed by the Central Design Bureau of Special Radio Materials for the manufacture of engine compressor blades, one of the most visible parts in RF band.
