Abstract
Inventia se refera la un antenuator de zgomot, utilizabil pentru amortizarea zgomotului produs de jetul unui motor turboreactor. Atenuatorul de zgomot, conform inventiei, în scopul reducerii nivelului global de zgomot si al realizarii unei amestecari cît mai intense a gazelor de ardere cu aerul de aport, are dispus la exteriorul unei structuri de retistenta niste elemente profilate cu profilul sectiunii transversale în V, al carui vîrf este îndreptat spre axa jetului si al carui unghi de deschidere este variabil, micsorîndu-se progresiv dinspre amonte înspre aval într-o gama de variatie între 60 si 180 degree , elementul profilat prezentînd la capatul dinspre amonte o tesitura paralela cu axul jetului si perpendiculara pe planul de simetrie al profilului V.
