Siberian scientists intend to develop a material to reduce the noise made during aircraft landing
«We are talking about so-called adaptable or additive composite materials, which, without violating the integrity of a wing, will be able to create dome-shaped trailing-edge flaps and wing slats, and therefore to reduce aircraft landing noise to a level of a 'neighbourhood noise', not exceeding 80 decibels,» he said.
Ser’eznov explained that during landing of an aircraft, there are gaps between trailing-edge flaps, through which air penetrates at high speed and creates a strong noise. The new material will help to make such a wing, in which there will be no crevices between the flaps, and hence the noise level will be reduced by several times. Ser’eznov also clarified that such a material might be used in a real aircraft as early as next year.
