              在阿麗亞娜火箭攜帶衛星進入太空的過程中,釋放衛星之前,火箭前椎體連同側護罩,必須立刻與主火箭分離。分離過程由預負載的彈簧同步受控進行。該脫落過程必須保證絕對的線性運動,避免任何非線性的歪斜運動,從而導致損壞衛星。線性運動由三支米銥公司提供的拉繩式傳感器測量并保證。

              In order to be able to launch a satellite from the Areane rocket unobstructed into space, the nose cone section, together with the side shield, have to be separated from the main rocket immediately before the release of the satellite.Simultaneous and controlled activation of a series of preloaded springs, provide the propulsion force for the separation of the nose cone and side shield.It is of vital importance that the section separates itself in an absloute linear motion from the main rocket,with-out any non-linear tumbling movement that could cause damage to the satellite.The separation movement is controlled by 3 Drawwire sensors mounted on the booster rocket. The ends of the draw wires are attached to the nose cone section via a preset and rated breaking point connector. These connectors automatically disconnect the wire from the nose cone at the end of the measuringrange of the sensor. Immediately following the separation of the drawwire from the nose cone section, the draw wire is automatically retracted in its housing, in order to avoid damage to the satellite during its subsequent separation from the carrier.
