Abstract

The disclosure relates to a component device, in particular for a primary supporting component of an aircraft, the component device having a first component element, a second component element, a bonding providing a connection between the first component element and the second component element, and a detector device having at least one interior space sensor device configured to measure a change in a pressure and/or a concentration of a gas surrounding the interior space sensor device. The first component element, the second component element, and the bonding confine an interior space. The interior space sensor device is arranged in the interior space.

First claim

What is claimed is:

1. A component device for a primary supporting component of an aircraft, comprising:
a first component element;
a second component element;
a bonding which provides a connection between the first component element and the second component element; and
a detector device with at least one interior space sensor device that measures a change of the pressure and/or of a concentration of a gas surrounding the interior space sensor device;
wherein the first component element, the second component element, and the bonding confine an interior space;
wherein the interior space sensor device is arranged in the interior space;
wherein the interior space sensor device comprises a first interior space sensor that measures the absolute pressure of the gases surrounding the first interior space sensor, a second interior space sensor that measures the partial pressure of a gas surrounding the second interior space sensor, and a third interior space sensor that measures the concentration of a gas surrounding the third interior space sensor; and
wherein the interior space sensor device comprises a plurality of different second interior space sensors, each of which is configured to measure the partial pressure of a different gas, and/or a plurality of different third interior space sensors, each of which is configured to measure the concentration of a different gas.

2. The component device of claim 1 , wherein the detector device comprises an outer space sensor device that measures the change of the pressure and/or of the concentration of a gas surrounding the outer space sensor device, and wherein the outer space sensor device is arranged outside of the interior space.

3. The component device of claim 1 , further comprising a self-testing arrangement configured to heat or cool the interior space sensor device and/or the outer space sensor device.

4. The component device of claim 1 , further comprising a pressure compensation arrangement that compensates pressure differences between the interior space and the surroundings of the component device, wherein the pressure compensation arrangement comprises a gas reservoir arranged in the interior space and/or a pressure relief valve interconnecting the interior space with the surroundings of the component device.

5. A component device for a primary supporting component of an aircraft, comprising:
a first component element;
a second component element;
a bonding which provides a connection between the first component element and the second component element, wherein the first component element, the second component element, and the bonding confine an interior space;
a detector device with at least one interior space sensor device that measures a change of the pressure and/or of a concentration of a gas surrounding the interior space sensor device, wherein the interior space sensor device is arranged in the interior space; and
a pressure compensation arrangement that compensates pressure differences between the interior space and the surroundings of the component device, wherein the pressure compensation arrangement comprises a gas reservoir arranged in the interior space.

6. The component device of claim 5 , wherein the second interior space sensor is a coated optical fiber.

7. A method for detecting a damage of a bonding for a component device, comprising the steps of:
providing a component device comprising two component elements connected by the bonding and an interior space fluidically connected to the bonding, wherein the interior space is hermetically sealed for at least one type of gas;
detecting the pressure and/or the concentration of the gas in the interior space;
determining a damage of the bonding if a change in pressure and/or in concentration above a predetermined threshold value is determined,
detecting the pressure and/or the concentration of the gas outside of the component device; and
determining a damage of the bonding if time dependent measurements of the pressure and/or time dependent measurements of the concentration of the gas in the interior space and outside of the interior space correlates.

8. The method of claim 5 , further comprising:
monitoring time dependent measurements of the pressure and/or time dependent measurements of the concentration in the interior space over a predetermined period of time; and
determining a damage of the bonding if a deviation of the time dependent measurements of the pressure from predetermined time dependent pressure measurements is above a predetermined threshold value.

9. A method for detecting a damage of a bonding for a component device, comprising the steps of:
providing a component device comprising two component elements connected by the bonding and an interior space fluidically connected to the bonding, wherein the interior space is hermetically sealed for at least one type of gas;
detecting the pressure and/or the concentration of the gas in the interior space;
determining a damage of the bonding if a change in pressure and/or in concentration above a predetermined threshold value is determined;
detecting the pressure and/or the concentration of additional gas in the interior space, the additional gas being different from the gas; and
determining a damage of the bonding if a change of the pressures above a predetermined threshold value is determined.

10. A method for detecting a damage of a bonding for a component device, comprising the steps of:
providing a component device comprising two component elements connected by the bonding and an interior space fluidically connected to the bonding, wherein the interior space is hermetically sealed for at least one type of gas;
detecting the pressure and/or the concentration of the gas in the interior space;
determining a damage of the bonding if a change in pressure and/or in concentration above a predetermined threshold value is determined;
detecting the pressure and/or the concentration of the gas in the interior space at multiple positions; and
localizing the damage of the bonding by determining the pressure differences and/or concentration differences between the individual positions.
