The invention discloses a water sensor and an overwater floating recorder with the same, and belongs to the technical field of avionics. The water sensor comprises a first metal plate and a second metal plate which are arranged in parallel and do not contact each other. One metal plate is connected to one electrode of a power supply after connected in series with a relay, and the other metal plate is connected to the other electrode of the power supply. The two metal plates are arranged in a protective shield with insulating property. One end face of the protective shield is provided with a plurality of holes. The two metal plates are communicated with the outside through the holes. The four corners of the protective shield are each provided with a fixing end used for fixing the water sensor into the overwater floating recorder. The relay is used for controlling current on-off of an electric detonator inside the overwater floating recorder. When seawater enters the gap between the two metal plates of the water sensor through the holes (2), the resistive material is changed from air to water, the current in the circuit becomes larger, and the relay can work normally to pop up the overwater floating recorder.
Description
technical field [0001] The invention belongs to the technical field of avionics, and in particular relates to a water sensor and a water floating recorder with the same. Background technique [0002] With the gradual increase of combat / training missions of fighter jets at sea, the probability of a fighter jet crashing at sea also increases. The traditional aircraft "black box" does not have the function of floating after entering the water. Although the existing "black box" is equipped with underwater positioning beacons, due to the limitation of salvage methods and equipment, the "black box" that has fallen into the deep sea can only "Hopeful, but unattainable". [0003] The water floating recorder can be ejected from the aircraft body after the aircraft falls into the water, and float on the sea surface, so that the flight record data of the aircraft is still complete and reliable after the aircraft falls into the water. The resistivity of seawater and river water is qui...
