BRMU9000503Y1 - aircraft black box coupled safety device - Google Patents

Abstract

Safety device attached to aircraft black box. The present object refers to an aeronautical safety device coupled to the aircraft black box, which will be triggered when the equipment submerges to a certain depth after an air accident occurred in oceans, rivers or lakes. The device has an inflatable bag developed in waterproof material like nylon and the like; When it reaches a certain depth the equipment will automatically turn on and the bag will inflate, causing the black box to float in the water.

1/4 "SAFETY DEVICE COUPLED IN AIRCRAFT BOX

This object refers to an aeronautical safety device attached to the aircraft's black box, which will be activated when the equipment submerges to a certain depth, after an air accident occurred in oceans, rivers or lakes. The device has an inflatable bag developed in waterproof material like nylon and the like; when reaching a certain depth the equipment is automatically activated and the bag inflates, causing the black box to float in the water.

The present object is intended to allow the aircraft's black box to be rescued in the event of air accidents occurring in oceans, rivers or lakes, where the aircraft tends to sink, taking with it the most important equipment to be analyzed afterwards. of an accident.

When analyzing the state of the art, in order to prove the novelty, we found the patent application PI0201704-0, “System for the Recovery of Aircraft Maintenance Documents”, deposited on 05/08/2002, which refers to a system for recovery of copies of paper documents. As you can see, there is nothing that resembles the object of the present application that deals with a device to facilitate the rescue of the aircraft black box, through an inflatable bag that is automatically activated when submerged to a certain depth.

In cases of accidents in oceans, for example, where the depth is very large, we can observe the difficulty of specialists in locating the black box, which sinks along with the other components of the aircraft.

The device is automatic, that is, when the aircraft falls into an ocean and the black box submerges to a certain depth, the device is automatically activated. A depth gauge with sensor sends a signal to the control unit, upon recognizing the message the inflating system is activated so that the bag is inflated. Its operation can be through the decomposition of sodium azide, releasing nitrogen responsible for inflating the bag, similar to that of a conventional air bag used in vehicles and also through a small high-pressure cylinder of non-oxidizing gas, similar to vests saves lives used on aircraft. The moment the bag inflates completely, it will be responsible for the fluctuation of the aircraft's black box. After filling the bag, it will not empty, so that the black box continues to float in the water.

is The safety device is inserted and fixed in a compartment developed in stainless steel and the like with a lid on its upper part, this compartment is fixed to the outside of the black box, using screws and the like. When activated, the compartment opens and releases only the inflatable bag, connected to the nylon straps that secure the bag to the entire compartment with the device. Upon reaching the surface, the black box, along with the compartment, will float, so the compartment needs to be developed in light and resistant material.

As the device is attached to the outside of the black box25, there is no need to tamper with its original shield or even change its shape or mechanisms. The device in question can be attached to conventional black boxes, already used today by aircraft.

For a perfect visualization and understanding of the “SAFETY DEVICE COUPLED IN BLACK AIRCRAFT BOX”, in question follow the illustrative drawings, where:

Fig. 1 - It presents a perspective view of the object in question fixed to the black box, with a close up on the compartment with the device in question, showing its interior;

Fig. 2 - It presents a transparent top view of the object in question, with a stock exchange inflation system through the decomposition of sodium azide;

Fig. 3 - It presents an illustrative view of the object in question after being activated, with the bag already inflated.

Fig. 4 - It presents a transparent top view of the object in question, with the bag's inflating system through a small non-oxidizing gas high-pressure cylinder.

According to the illustration and its details, the “SAFETY DEVICE COUPLED IN BLACK AIRCRAFT BOX”, is characterized by a compartment developed in stainless steel and similar (1) with a lid on its upper part (2) fixed to the box - conventional aircraft black (3) using screws and the like (6), having a depth gauge (5) and a safety device (4) inside, which will be activated automatically, when the equipment submerges to a certain depth , after an air accident occurred in oceans, rivers or lakes; the safety device (4) also has a control unit (7) that recognizes the signal sent by the depth gauge (5) and sends a signal to the inflating system (8) so that the bag (9) is inflated; the inflatable bag

4/4 (9) remains attached to the compartment (1) using nylon straps and the like (10).

The bag inflating system (8) works by decomposing sodium azide (11), releasing nitrogen responsible for inflating the bag (9),

The bag's inflating system (8) can also function through a small high-pressure cylinder of non-oxidizing gas (12).

The depth gauge (5), the control unit (7) and the inflation system (8) are interconnected via wiring (13).

For the advantages it offers and for having truly innovative characteristics, the ‘‘ SAFETY DEVICE COUPLED IN BLACK AIRCRAFT BOX, meets the necessary conditions to deserve the Patent of

Utility.
