Claims (12)

1. Vingeprofilbagkantindretning til støjreduktion, omfattende: en forhøjning (28) langs en bagkant af en vingeprofil; hvor forhøjningen omfatter en første (32) og anden (34) side, som hver især konvergerer fra en sugeside (36) og en trykside (38) af bagkanten til et agtervendende toppunkt af forhøjningen, kendetegnet ved, at siderne af forhøjningen er konkave, og forhøjningen (28) er perforeret med en flerhed af huller (44B) med mindst to forskellige diametre.
2. Vingeprofilbagkantindretning ifølge krav 1, hvor den første af forhøjningen forløber mellem toppunktet og sugesidehjørne af bagkanten, og den anden anden side af forhøjningen forløber mellem toppunktet og en sugesidehjørne af bagkanten.
3. Vingeprofilbagkantindretning ifølge krav 1, hvor toppunktet af forhøjningen er takket.
4. Vingeprofilbagkantindretning ifølge krav 1, hvor forhøjningen omfatter en kerne af lydabsorberende materiale.
5. Vingeprofilbagkantindretning ifølge krav 1, hvor forhøjningen omfatter en kerne af åndbart, lydabsorberende materiale, og begge sider af forhøjningen er perforeret med huller, som tilvejebringer trykudligning mellem de to sider af forhøjningen gennem den åndbare kerne.
6. Vingeprofilbagkantindretning ifølge krav 1, hvor mindst én af siderne af forhøjningen omfatter en spoiler i form af en sekundær forhøjning.
