Abstract
The present invention falls within the scope of soundproofing structures for aircrafts, disclosing a double-sided noise barrier suitable for ground run-up enclosures. Therefore, it is proposed a support structure formed by two side surfaces, each side surface having sound insulating plates mounted thereon, providing a 360° soundproofing space around it. By means of the technical advantageous provided with the use of a double-sided noise barrier, the present invention discloses GRE structures which incorporates such barrier, that enable optimization of space in the assembly of a set of individual GREs.
Claims22
