Abstract

L'invention concerne une chambre de combustion (6) pour turbomachine à détonation rotative, la chambre de combustion (6) comportant une paroi intérieure (14) annulaire et un carter extérieur (16) annulaire, la paroi intérieure (14) et le carter extérieur (16) étant concentriques et s'étendant le long d'un axe longitudinal (X-X), le carter extérieur (16) entourant la paroi intérieure (14), la paroi intérieure (14) et le carter extérieur (16) délimitant entre eux une cavité de détonation (18), la chambre de combustion (6) étant caractérisée en ce qu'elle comporte, en outre, un transducteur électromécanique (22), le transducteur électromécanique (22) comprenant au moins une surface active (24), le transducteur électromécanique (22) étant agencé de sorte que la surface active (24) soit disposée dans la cavité de détonation (18), le transducteur électromécanique (22) étant adapté pour générer de l'énergie électrique lorsqu'une force pressante est exercée sur la surface active (24) du transducteur électromécanique (22).The invention relates to a combustion chamber (6) for a rotary detonation turbomachine, the combustion chamber (6) having an annular inner wall (14) and an annular outer casing (16), the inner wall (14) and the casing. outer (16) being concentric and extending along a longitudinal axis (XX), the outer casing (16) surrounding the inner wall (14), the inner wall (14) and the outer casing (16) delimiting between them a detonation cavity (18), the combustion chamber (6) being characterized in that it further comprises an electromechanical transducer (22), the electromechanical transducer (22) comprising at least one active surface (24) , the electromechanical transducer (22) being arranged so that the active surface (24) is disposed in the detonation cavity (18), the electromechanical transducer (22) being adapted to generate electrical energy when a pressing force is exerted on the active surface (24) of the transducer Electromechanical uctor (22).
