| 发明名称 | System for reducing the dynamic behavior of the movable segment of a deployable nozzle for a rocket engine | ||
| 摘要 | A deployable nozzle for a rocket engine, the nozzle including at least a stationary divergent segment and a movable divergent segment that is coaxial about the stationary divergent segment and configured to move along the stationary divergent segment from a retracted position towards a deployed position. The deployable nozzle further includes a transverse stiffener that is prestressed in tension and that extends transversely relative to the movable divergent segment in a vicinity of a downstream end of the movable divergent segment between at least two points at a periphery of an inside wall of the movable divergent segment. | ||

| 主权项 | 1. A deployable nozzle for a rocket engine, the nozzle comprising: at least a stationary divergent segment; a movable divergent segment that is coaxial about the stationary divergent segment and is configured to move along the stationary divergent segment from a retracted position towards a deployed position; and a transverse stiffener that is prestressed in tension and that extends transversely relative to the movable divergent segment in a vicinity of a downstream end of the movable divergent segment between at least two points at a periphery of an inside wall of the movable divergent segment. | ||
