Abstract: A store ejector includes at least one fluid pressure operated ram (4). In use the ram (4) engages and ejects a store (5). The ejector includes a source of fluid under pressure and a throttle valve connected between the source of fluid under pressure and the ram (4). A pressure sensor detects the pressure supplied to the ram and an extension sensor monitors the extension of the ram. A computer receives inputs from the pressure and extension sensors and provides a control output to the throttle valve to control the valve to provide a predetermined applied thrust profile to the store.
