Power transfer unit (original) (raw)
In aviation, a power transfer unit (PTU) is a device that transfers hydraulic power from one of an aircraft's hydraulic systems to another in the event that second system has failed or been turned off. The PTU is used when, for example, there is right hydraulic system pressure but no left hydraulic system pressure. In this example, the PTU transfers hydraulic power from the right hydraulic system to the left hydraulic system. A PTU consists of a hydraulic motor paired with a hydraulic pump via a shaft.

| dbo:abstract | In aviation, a power transfer unit (PTU) is a device that transfers hydraulic power from one of an aircraft's hydraulic systems to another in the event that second system has failed or been turned off. The PTU is used when, for example, there is right hydraulic system pressure but no left hydraulic system pressure. In this example, the PTU transfers hydraulic power from the right hydraulic system to the left hydraulic system. A PTU consists of a hydraulic motor paired with a hydraulic pump via a shaft. As the connection is purely mechanical, there is no intermixing of hydraulic fluid between the left and right hydraulic systems during PTU operation. (en) Dans l'aviation, un Power transfer unit (littéralement unité de transfert de puissance) abrégé par son sigle PTU est un dispositif qui transfère la puissance hydraulique de l'un des systèmes hydrauliques d'un avion à un autre en cas de panne ou de désactivation du second système. Le PTU est utilisé lorsque, par exemple, il y a une pression du système hydraulique droite mais aucune pression du système hydraulique gauche. Dans cet exemple, le PTU transfère la puissance hydraulique du système hydraulique droit au système hydraulique gauche. Un PTU se compose d'un moteur hydraulique couplé à une pompe hydraulique via un arbre. Comme la connexion est purement mécanique, il n'y a pas de mélange de fluide hydraulique entre les systèmes hydrauliques gauche et droit pendant le fonctionnement du PTU. (fr) |
