Title (EN) CONSTANT VOLUME COMBUSTION CHAMBER AND ASSOCIATED TURBINE ENGINE COMBUSTION SYSTEM
(FR) CHAMBRE DE COMBUSTION A VOLUME CONSTANT ET SYSTÈME DE COMBUSTION POUR TURBOMACHINE ASSOCIE
Abstract:
(EN) The invention relates to a constant volume combustion chamber (1) for a turbine engine, the chamber (1) comprising an intake port (6), an exhaust port (7), and a first rotary seal (11) arranged opposite the intake and exhaust ports (6, 7) and configured to rotate about an axis (R) in a first direction of rotation, the first seal (11) comprising an opening (110) intended for engaging alternately with the intake and exhaust ports (6, 7) during the rotation of the first seal (11). The chamber also comprises at least one second rotary seal (12) arranged opposite the intake and exhaust ports (6, 7) and configured to rotate about said axis (R) in a second direction of rotation opposite to the first direction, said second seal (12) comprising an opening (120) intended for engaging alternately with the intake and exhaust ports (6, 7) during the rotation of said second seal (12), said first and second seals (11, 12) being synchronised and configured so that the respective openings (110, 120) thereof cross alternately facing the intake and exhaust ports (6, 7).
(FR) Une chambre de combustion à volume constant (1) pour turbomachine, la chambre (1) comprenant un port d'admission (6), un port d'échappement (7), et un premier obturateur (11) rotatif disposé en regard des ports d'admission et d'échappement (6,7) et configuré pour tourner autour d'un axe (R) dans un premier sens de rotation, le premier obturateur (11) comprenant une lumière (110) destinée à coopérer alternativement avec les ports d'admission et d'échappement (6,7) lors de la rotation du premier obturateur (11). La chambre comprend en outre au moins un second obturateur (12) rotatif disposé en regard des ports d'admission et d'échappement (6,7) et configuré pour tourner autour dudit axe (R) dans un second sens de rotation opposé au premier sens, ledit second obturateur (12) comprenant une lumière (120) destinée à coopérer alternativement avec les ports d'admission et d'échappement (6,7) lors de la rotation dudit second obturateur (12), lesdits premier et second obturateurs (11,12) étant synchronisés et configurés pour que leur lumière respective (110, 120) se croisent alternativement en regard des ports d'admission et d'échappement (6,7).
