Abstract

A device for checking at least one pressurized testing tool for a fluid circuit of an aircraft includes at least one tank that includes at least one connection to connect a pressurized gas supply and at least one connection system arranged to connect at least one pressurized testing tool. This device makes it possible to perform preventive checks on pressurized testing tools without having to immobilize an aeroplane on an assembly line.

Claims

1. A device for checking at least one pressurized testing tool for a fluid circuit of an aircraft, the device comprising:

at least one tank including at least one first connection to connect a pressurized gas supply and at least one second connection to connect to the at least one pressurized testing tool, the at least one pressurized testing tool being separate from the device; and

at least one connection system arranged to connect the at least one pressurized testing tool to the at least one tank,

wherein the connection system includes at least one opening enabling communication between the inside and the outside of the vat and a joining system configured to hold a closing element in a position in which the closing element closes the opening,

the device further comprising an interface including a wall traversed by a window the shape of which is adapted to the shape of the at least one pressurized testing tool to be checked, said wall having an internal face with a peripheral bearing surface configured to cooperate with a bearing surface of the opening.

2. The device according to claim 1, wherein the at least one tank is a vat with a capacity equal to or greater than 200 L.

3. The device according to claim 2, further comprising at least a second vat, each of the vat and the second vat having a connection and a connection pipe configured to link the two connections and to enable communication between at least the vat and the second vat.

4. The device according to claim 1, wherein the connection system includes:

an outer chamber delimited by a back and a peripheral wall having an edge corresponding to the bearing surface of the opening, and

a conduit for communicating the outer chamber with the inside of the vat.

5. The device according to claim 1, further comprising centering means to facilitate the positioning of an interface or of a door in relation to the opening.

6. The device according to claim 1, further comprising a false door for closing the opening.

7. The device according to claim 1, further comprising a second tank, the second tank being a line.

8. The device according to claim 7, wherein the internal diameter of the line is between 40 and 100 mm and/or the length of the line is between 3 and 10 m.

9. The device according to claim 7, wherein the line includes a reducing valve linked to the connection for connecting the pressurized gas supply.

10. The device according to claim 1, further comprising a moveable chassis carrying the at least one tank.

11. The device according to claim 10, wherein the moveable chassis includes a frame moveable between a blocking position in which at least one portion of the moveable frame is arranged opposite the connection system configured to connect at least one pressurized testing tool and a released position in which the moveable frame releases said connection system and enables placement of an interface, a false door, a pressurized testing tool, or any other closing element.

12. The device according to the claim 11, wherein the moveable frame includes two uprights, each having an aperture in which is seated a pivot axis carried by a static frame, at least one of the uprights having a hook configured to cooperate with a pin rigidly connected to the static frame in the blocking position.

13. The device according to claim 10, wherein the moveable chassis includes a moveable shelf positioned beneath a line acting as the tank.

14. The device according to claim 10, wherein the moveable chassis includes a structure surrounding the at least one tank in the form of a vat, a portion of which forms a supporting element to which the at least one tank in the form of a line is attached.

15. The device according to claim 14, wherein the supporting element is arranged vertically so that the line is arranged in a vertical plane.

16. The device according to claim 14, wherein the line follows an S-shaped path.
