Multi-axis vectorable exhaust nozzle

摘要

A convergent-divergent exhaust nozzle is mounted to an exhaust duct of a jet aircraft engine by a circumferentially-spaced set of hydraulic cylinders. The cylinders are interconnected in captured flow via hydraulic circuits which allow the cylinders to function as a gimbal mounting. This mounting allows the entire nozzle to vector the exhaust without additionally loading the divergent flaps with vectored exhaust so that cool, low pressure ram air can be channeled directly to the divergent flaps for efficient cooling.
