The technical field to which the invention relates.

The invention relates to the aircraft using a multiple-system coupling devices.

In the following, for simplicity of the description considers aircraft type aircraft.

The level of technology

In the context of the development of new aircraft require manufacturers of aircraft to provide aircraft with a more flexible salons. Airlines want to be able to reconfigure the layout of the beauty of its aircraft within increasingly short time to as little as possible to obezdwijivanie their aircraft. Their aim is to completely reconfigure the cabin in the cargo area, which is very fast. In this perspective, the idea of the invention consists in adapting quickly established models of distributed systems (air, water, electrical, oxygen,...) and be installed in the cabin units (blocks, cooking, seats, containers,...)in order to provide this flexibility of the cabin.

Be the solution of the technical problem is to provide installation of these systems:

- more flexible

- faster

- more simple, and

- a more integrated way.

When considering an exemplary modification of the inside of the cabin, as illustri is : on figa and 1B the configuration of the front of the aircraft 10 in the region of 11 modified between the illustration on figa and illustration of figure 1 by replacing the rows of two seats in rows of three seats, for example, to increase the surface area allocated to economy class, business class. Each of these modifications include the reduction of the distance between two consecutive rows of seats, and, therefore, modification level systems for air supply, electricity, ... passengers.

Therefore, it is necessary to provide interfaces that are available throughout the cabin of the aircraft, to ensure that all possible situations without the need for modification of traces of different distributed systems.

In the above example more close transfer seats need to apply air to the diffusers 21 and electricity for individual highlights 20 and LCD (liquid crystal display) for each passenger, as illustrated in figa and 2B.

As illustrated in figa, 3B and 3C, the air exhaust system (line 30) passes over the hangers to connect with air diffusers 31.

As for the distribution of electricity, there are electrical connections through the floor, for example, LCD screens installed on the seat, through weelk is for individual lighting.

In the case of oxygen to be fed through oxygen masks in the event of seal failure, you can use

any pyrotechnic cartridges 41: in case of depressurization, as illustrated in figure 4, fall oxygen mask 40. Each passenger pulls the mask quick movement to start a chemical reaction inside the corresponding cartridge 41, which provides oxygen. In this case, it is necessary to provide an electrical signal to release each oxygen masks in case of depressurization,

any oxygen cylinders 50, as illustrated in figa, or device type low boxes: with both of these types of oxygen equipment should be distributed via line 51, as illustrated in figv, to masks, and therefore in the cabin must be provided for connection to oxygen in addition to electric signals.

In the case of blocks of cooking (sinks or kitchen equipment for cooking for passengers and containing trolleys for food), you need to submit, in particular, water, electricity, and cooling air.

Installation of these various systems independent from each other with a separation between the air supply and electric cables, for example. When an airline buys a plane, determines the definition of systems on the I power of beauty. Any modification of the layout of the cabin requires a long and expensive process, which makes it necessary to re-development, certification.

One of the technical problems that need to be resolved by the developers of the aircraft is therefore to make available for layout interior interfaces fairly regular manner along the inner walls of the cabin, to connect different systems, while at the same time, the modularity of the cabin, i.e. a number of configurations for the layout of the latter.

With the device according to the invention it is possible to offer along the inner wall of the cabin of the plane of the slot, spaced from each other by a given distance (Δ mm), and each of these jacks provide connection systems that are required for a number of seats, for example. Thus, as illustrated in figure 6, the socket can be installed in position 60 on the baseboard 61 on the side of the cabin, to connect with an air line 62.

These jacks can also be placed in different locations along the aircraft cabin, for example at the level of the floor or ceiling depending on the location of the systems, as illustrated in figa, 7B and 7C. Electric line 70, an air line 71, which is located behind the wall or skirting Board (figa), ceiling (pigv) or under the floor (figs) and the socket 72 is also shown on these drawings.

Below will be described a few embodiments of the device according to the invention.

The first variant of realization of the device according to the invention

In this first embodiment, the connecting device according to the invention provides the compound as a gas, for example air, electricity or electrical signals, which are two systems that do not require limiting the separation.

As illustrious is by Piga and 8B, the connecting device further consists of two parts:

the slot 80, which is attached between the air line 82 and fittings 83 salon (plinth) and which receives the first electric cables 84,

connector 81 connected with the systems of the interior, in particular through the second electrical cables 85, able to be inserted into the slot 80, as illustrated in figa and 8B, before and after connection of the two parts 80 and 81.

As illustrated in figa chamber 90 contains:

- the first section 91, which forms the basis, here is a triangular base, provided with at least one aperture 92 that allow it to attach to the backbone of the release of gas or water, is pierced in its center passage 93,

- the second section 94, which forms a hollow cylindrical part which is firmly attached to the first section perpendicular to the latter, so that the hollow section 95 of this part, containing protivovozrastnoy valve 107 communicates with passage of the first section.

This second section 94 contains three concentric area, which are, starting from the middle:

the first cylindrical sleeve 96, able to let liquid or gas,

the first cylindrical electrical connecting section 97, which forms the end of the first electric cables 99,

the first locking ring 98, for example, the R, self-latching type.

As illustrated in figv, the plug 10 itself also contains three concentric area, which are, starting from the middle:

the second cylindrical sleeve 101, able to let liquid or gas,

the second cylindrical electrical connecting section 102, forming the end of the second electrical cables 103,

the second locking ring 104, is able to act together with the first ring 98 to firmly fasten the plug 100 and the slot 90, as illustrated in figs.

As illustrated in fig.9D, the second cylindrical sleeve 102 can be mainly connected with ringed pipe 105, with which you can get some flexibility during installation systems in the area, and with which it is possible to avoid transmission of forces and displacements between the components that are installed in the cabin, and Jack.

When, as shown in Figi, the connector 100 is connected with the socket 90, is the agreement:

- holes 96 and 101 of the first and second cylindrical sleeves, allowing gas 112 to flow into the United system,

the first and second connecting sections 97 and 102, allowing the second electrical cable 103 connected systems to connect with the first electrical cable that supplies electricity or electrical signals 99.

The slot 90 may be attached to master the eh air conditioning. Electrical cables are connected around the air connection subject to the restrictions on the installation of aviation electricians, for example, related to the radius of curvature.

When no plug 100 is inserted into the slot 90, protivovozrastnoy valve 107, shown in fig.9D (system of a ball 110 + springs 111), will block the gas outlet and to provide sealing. Indeed, when the plug 100 will be connected to the socket 90, the spring protivojazvennogo valve 107 is compressed and the ball 110 is pushed back to allow gas to pass through this valve. Protivovozrastnoy valve may be a valve without any gaskets to avoid any maintenance operations. In this embodiment, protivovozrastnoy valve 107 uses a ball 110 and the spring 111, but can include any other form known to the specialist in order to make the device easier.

As for the electrical connections, each slot 90, you can install a protective cover to prevent condensation in the cavity of the socket. Thus, several nests may be located in the cabin to meet the condition of the flexibility of the layout of the salon without any risk of air leakage.

This first version of the implementation has the following advantages:

- two systems: gas + electricity is (and / or electrical signals) can be connected at the same time;

- for the two compounds is used only shut-off system;

- no risk of error in connection or due to forgetfulness; for multiple systems using a single plug;

for both systems is guaranteed seal (air, electric), whether the connection mode or end key.

The second variant of realization of the device according to the invention

In the first embodiment, a multi-system connective device provides gas or electrical connections that need to be done to your systems. But you can also provide a connection to other systems by providing modularity in connection liquid-electricity. This second variant implementation also allows to make the water connection for use, for example, to blocks of cooking.

In this second embodiment, the corresponding slot 90 and the plug 100 are liquid connection in the middle and the electrical connection at the periphery, which can be modular and can be removed or not depending on the need. Indeed, for reasons of separation between the systems is possible not to leave electrical connections around water connections.

The advantage of this second variant implementation is ensured by the development of one is the same multiboot coupling devices, which may be modular, which enables the connection of multiple systems and that, moreover, corresponds to the existing aviation standards.

A third option exercise device according to the invention

In this third embodiment of the invention a high-speed lock ring in a self-type is replaced with a quick quarter-turn shut-off system called "Quick disconnect".

In the event of such locking systems moving to the locking ring is rotated around the Central axis along the ring unlike constipation self-latching type, where the movement is along the axis. This quarter-turn locking has the advantage of being less bulky locking device.

The fourth option exercise device according to the invention

In this fourth embodiment of the invention uses electrical connections for the transmission of high-performance signals Ethernet networks.

As illustrated in figa and 10B, it is possible to use the electrical connections 120 type quadrax or fiber optic connection 121 with the Central passage, respectively.

The fifth option exercise device according to the invention

In this fifth embodiment of the invention, as illustrated in figure 11, is used in a multi-system connective device is ustwo, various sites which are not concentric.

Each socket and each corresponding plug contains four holes 130, 131, 132 and 133, respectively, which provides:

- electric connection,

air connection

- water connection, and

- oxygen compound,

moreover, a distinction is made 134 between the first two joints and the last two compounds.

Such an implementation option has therefore the advantage of ensuring the integration of the principles of separation between different systems.

Note here that said heat exchanger releases heat to external heat carrier flowing and/or circulating from source outside of aircraft electronic system via heat exchanger to heat absorber outside of said electronic system. Internal heat carrier flows from heat exchanger toward, at least, one electronic component, and/or circulates in closed circuit.

EFFECT: higher efficiency of cooling.

SUBSTANCE: set of inventions relates to aircraft air conditioning systems. System 1 comprises first line 6 to feed cold air at actual temperature T1act, second line 14 to bleed air portion from first line 6 at branch point 10 into several zones 2, 4 of aircraft, and first zone feed line 24. Raw cold air at T1act is fed into first line 6. Cold air portion is vented into second line 14 at branch point 10. Cold air of first line 6 is fed into extra zones located downstream and/or upstream of said branch point 10. Warm air is fed via control valve 12 into second line so that air therein is heated to actual temperature T2act higher than 0°C. Air portion of second line 14 is fed via first zone line 24 into first zone 2. Warm air is fed via second control valve 26 into first line feed line so that air in first zone feed line 24 is heated to actual temperature Tzf1act. Air is fed via first line into mixing chamber whereto circulated air is fed.

EFFECT: ruled out icing of aircraft air conditioning system.
