Title (EN) INLET PARTICLE SEPARATOR SYSTEM FOR A GAS TURBINE ENGINE
(FR) SYSTÈME À FILTRE SÉPARATEUR DE PARTICULES POUR TURBINE À GAZ
Abstract:
(EN) Embodiments include an inlet particle separator system for a gas turbine engine. The inlet particle separator system includes an inertial particle separator that separates incoming air into a cleaned air flow and a scavenge flow. Embodiments may also include an ejector that provides a draw on a scavenge duct and entrains the scavenge flow into a charged flow, e.g., such as the output of a first stage fan. The ejector may have a variable output.
(FR) L'invention concerne un système à filtre séparateur de particules pour turbine à gaz. Le système à filtre séparateur de particules comporte un séparateur inertiel de particules qui sépare l'air entrant en un flux d'air propre et un flux de purge. Certains modes de réalisation peuvent également comprendre un éjecteur qui produit une aspiration sur un conduit de purge et entraîne le flux de purge dans un flux chargé, tel que la sortie d'un ventilateur mono-étagé. L'éjecteur peut avoir une sortie variable.
