航空航天测量应用-wire

在阿丽亚娜火箭携带卫星进入太空的过程中，释放卫星之前，火箭前椎体连同侧护罩，必须立刻与主火箭分离。分离过程由预负载的弹簧同步受控进行。该脱落过程必须保证绝对的线性运动，避免任何非线性的歪斜运动，从而导致损坏卫星。线性运动由三支米铱公司提供的拉绳式传感器测量并保证。

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.
