Abstract

PURPOSE:To provide a small flight recorder floating device capable of causing a large and heavy flight recorder to be afloat. CONSTITUTION:This device is equipped with a flight recorder 2, a submerged detecting section 5 for detecting water, a gas supply section 4 actuated upon the detection of water with the section 5, and an air bag 6 inflated with gas fed from the section 4. When the flight recorder 2 is submerged, the section 5 detects water and drives the section 4, thereby inflating the air bag 6. As a result, the flight recorder 2 becomes afloat.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flight recorder levitation device for levitating a flight recorder mounted on an airplane above the water so that the flight recorder does not sink when the flight recorder falls into the sea.

[0002]

2. Description of the Related Art An airplane is equipped with a flight recorder for collecting information such as elucidation of the cause of a crash when an accident occurs and the vehicle crashes. Therefore, the flight recorder has a structure that is not damaged by a dropped impact and is easily collected.

As a structure that can be easily recovered, a conventional flight recorder is housed in a float shell having sufficient buoyancy to float the flight recorder so that the flight recorder will not be submerged in the sea when it falls into the sea or the like. .

[0004]

In recent years, the amount of information recorded in flight recorders has increased more and more, and therefore the shape of flight recorders has become larger and the weight thereof has also increased. In the conventional float recorder levitation device using the float shell, as the shape of the flight recorder increases and the weight increases,
In order to obtain sufficient buoyancy, the size must be increased. However, since the equipment mounted on the aircraft must be stored in a limited space, there is always a demand for miniaturization. Therefore, there has been a demand for a flight recorder levitation device which has sufficient buoyancy and is miniaturized in response to the increase in the size and weight of the flight recorder.

In view of such circumstances, the present invention provides a small flight recorder levitating apparatus capable of levitating a flight recorder having a large shape and weight.

[0006]

According to the present invention, there is provided a flight recorder, a submersion detecting section for detecting water, a gas supply section for generating a gas driven by water detection of the submersion detecting section, and a gas supply section It is characterized in that it is equipped with an airbag that is inflated by the gas.

[0007]

When the flight recorder is submerged in water, the submergence detection unit first detects the water and drives the gas supply unit to inflate the airbag. Due to the inflation of the airbag, the flight recorder is given buoyancy and floats above the water.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a flight recorder levitation device having a flight recorder 2, and the flight recorder 2 is housed in a float shell 3. Further, the float shell 3 is provided with a gas supply unit 4, a submergence detection unit 5, and a reduced airbag 6.

When the flight recorder levitation device 1 is submerged in water, the water enters the submergence detection unit 5, the submergence detection unit 5 detects the water, drives the gas supply unit 4, and the airbag 6 Is filled with gas and inflated, and the inflated airbag 6 has sufficient buoyancy to levitate the flight recorder levitation device 1 and levitates the flight recorder levitation device 1.

Further details will be described with reference to FIG.

The submergence detection section 5 comprises a water sensor 7, a determination circuit 8 and a battery 9, and the gas supply section 4 comprises a drive circuit 10, an ignition battery 11, an ignition section 12 and a gas generation section 13. There is.

The battery 9 constantly supplies electric power to the judgment circuit 8 to keep the judgment circuit 8 in operation. When the water sensor 7 detects water, the determination circuit 8 detects that the flight recorder levitation device is submerged, and the drive circuit 10
To operate. The drive circuit 10 operates a switching circuit (not shown) to energize the ignition unit 12 and
2 burns a gas generating substance to generate a gas for levitation. The levitation gas inflates the airbag 6 and the flight recorder levitation device floats as the airbag 6 inflates.

[0014]

As described above, according to the present invention, since the buoyancy of the flight recorder levitation device is obtained by the air bag, the float shell may be small, and the air bag is normally reduced to the float shell. Since it is stored, the volume of the entire flight recorder levitation device is significantly reduced.
