Abstract
Lost-fluid hydraulic actuation system. This system makes it possible to control for a short time an element (168) in an autonomous working unit, particularly a rocket, with an onboard means (100) connected to the unit. Hydraulic fluid under pressure is introduced into the element (168) by a delivery pipe (141). A tank (130) supplies the hydraulic fluid used during the autonomous working, a helium bottle (110) puts the hydraulic fluid under pressure, and an evacuation pipe (171) evacuates the hydraulic fluid out of the autonomous unit after it has actuated the element (168).
