Sensor e.g. air data sensor, protection device for aircraft, has fixation unit with pin made up of magnetostrictive material such that pin is withdrawn from notch, when pin is subjected to magnetic field during reheating of sensor

摘要

The device has a detachable fixation unit (306) to maintain the device on an outer wall of an aircraft. The unit has a pin (307) inserted in a notch (308) of a clevis pin (301) to be introduced in openings of the wall. The pin (307) is made up of a magnetostrictive material such that the pin (307) is withdrawn from the notch, when the pin is subjected to magnetic field generated by an electromagnet during reheating of a sensor (200).
