Abstract
Pour empêcher la fuite des gaz à haute température autour des surfaces du cône de sortie et éviter ainsi leur détérioration et pour prévenir l'affaissement de ce cône de sortie lors de l'action des forces de décharge, on a prévu des cônes de sortie extensibles pour les tuyères des moteurs à réaction du type télescopique ou à << godet de reconnaissance >>. Les organes de blocage positifs sont utilisés pour maintenir les cônes de sortie dans leur position allongée à l'encontre des forces aérodynamiques et de pression interne rencontrées par la tuyère. Les organes de blocage servent aussi à bloquer les cônes d'extension de la tuyère dans leur position déployée.
