Title (EN) TURBOPUMP INDUCER AND TURBOPUMP
(FR) INDUCTEUR POUR TURBOPOMPE ET TURBOPOMPE
Abstract:
(EN) A turbopump inducer for stabilising the cavitation pockets occurring at the blades of the inducer, the inducer having a plurality of blades (10) disposed between an inner housing and an outer housing, each blade (10) having a lower surface and an upper surface (20), the upper surface (20) of at least one blade (10) having a cut-out portion extending substantially from the leading edge (22) of the blade (10) to a step surface (26) provided on the upper surface (20).
(FR) Inducteur pour turbopompe permettant de stabiliser les poches de cavitation apparaissant au niveau des pales de l'inducteur, l'inducteur comportant une pluralité de pales (10) disposées entre un carter interne et un carter externe, chaque pale (10) présentant un intrados et un extrados (20), l'extrados (20) d'au moins une pale (10) présentant un décaissement, le décaissement s'étendant sensiblement du bord d'attaque (22) de la pale (10) jusqu'à une surface de marche (26) agencée sur l'extrados (20).
