feuille de kirigami peut se d\u00e9former avec une grande amplitude et affecter l'augmentation de la tra\u00een\u00e9e avec la vitesse d'\u00e9coulement. Cette reconfiguration induite par l'\u00e9coulement est couramment trouv\u00e9e dans la nature, par exemple, les arbres, les feuilles et les plantes aquatiques ainsi que dans les applications d'ing\u00e9nierie, notamment les disques de drapage, l'actionnement passif et la r\u00e9cup\u00e9ration d'\u00e9nergie. Dans ce projet, nous nous sommes concentr\u00e9s sur le mod\u00e8le kirigami en boucle ferm\u00e9e et avons exploit\u00e9 sa d\u00e9formation quasi-axisym\u00e9trique sous \u00e9coulement pour programmer la stabilit\u00e9 a\u00e9rodynamique de fines feuilles circulaires. Nous avons construit un parachute d'un m\u00e8tre inspir\u00e9 du kirigami et l'avons test\u00e9 dans des conditions r\u00e9alistes en larguant une bouteille d'eau depuis un drone. Ces types de parachutes pourraient limiter les pertes de mat\u00e9riaux lors du largage a\u00e9rien humanitaire, r\u00e9duire les co\u00fbts et la complexit\u00e9 de fabrication et limiter les risques
