Device for the protection of a probe in the external hull of an airplane

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 The pin (307) is made up of a magnetostrictive material such that the pin (307) is withdrawn from the notch, when the pin is subjected to magnetic field generated by an electromagnet during reheating of a sensor (200).
