Title
(EN) SOUND INSULATING PANEL SUITABLE FOR USE AS A DEFLECTING SURFACE IN JET BLAST DEFLECTORS
(FR) PANNEAU D'ISOLATION ACOUSTIQUE APPROPRIÉ POUR ÊTRE UTILISÉ COMME SURFACE DE DÉVIATION DANS DES DÉFLECTEURS DE SOUFFLE DE RÉACTEUR
Abstract
(EN)
The present application relates to a sound insulating panel, suitable for use as a deflecting surface in jet blast deflectors. Therefore, it is described a jet blast deflector fence, comprised of detachable sound insulating panels, forming a modular deflecting and noise absorbing surface, covering its entire frontal area that is aligned with the aircraft. This approach favours not only the maintenance procedures of the fence, but also allows noise absorption, in addition to redirecting the high energy exhausted from a jet engine.
(FR)
La présente invention concerne un panneau d'isolation acoustique, approprié pour être utilisé comme surface de déviation dans des déflecteurs de souffle de réacteur. Par conséquent, l'invention concerne une barrière déflectrice de souffle de réacteur, constituée de panneaux isolants acoustiques détachables, formant une surface modulaire de déviation et d'absorption de bruit, couvrant toute la zone frontale qui est alignée avec l'aéronef. Cette approche favorise non seulement les procédures d'entretien de la barrière, mais permet également une absorption de bruit, en plus de rediriger l'énergie élevée évacuée par un moteur à réaction.
