Abstract

The invention belongs to the technical field of avionics and in particular relates to a flying parameter recorder capable of floating on the water. The flying parameter recorder comprises an upper separable component and a lower mounting frame which is directly fixed on an airplane, wherein a recorder component is arranged in the separable component filled with a foaming material; an electric initiator is arranged on the mounting frame; after the airplane crashes into the water, the electric detonator in the flying parameter recorder is detonated to be on fire, so that the separable component and the mounting frame fixed on the air plane can be separated from each other, and the separable component is pushed out and floats on the water. Under the common action of a water sensor, a battery box, a relay and a throwing separation device, the flying parameter recorder can enable the separable component to be popped out of the mounting frame to be popped out of the airplane body after falling into the water, so that the separable component can be prevented from sinking to the bottom of the water together with the airplane and can be easily found by searching staff.

Description

technical field

[0001] The invention belongs to the technical field of avionics, and in particular relates to a water floating flight parameter recorder. Background technique

[0002] At present, most domestic flight recorders follow the technical standard CTSO-C124a promulgated by the Civil Aviation Administration of China in 2003. This type of recorder is fixedly installed on the aircraft. When the aircraft crashes at sea, the recorder will sink into the deep sea together with the aircraft. The recorder is equipped with an underwater positioning beacon, which can detect the position of the recorder through sonar detection equipment, but the working distance of the underwater positioning beacon is only about 3km. If the recorder falls into the deep sea exceeding 3km, the recorder will be salvaged and recovered will be very difficult. On June 1, 2009, the Air France AF447 passenger plane crashed in the Atlantic Ocean. It took search personnel 2 years and 32 million euros to...
