Abstract

A measuring device with at least one fluid channel for conveying a measuring fluid, wherein the fluid channel includes at least one inlet for the entry of the measuring fluid into the fluid channel and at least one outlet for the exit of the measuring fluid from the fluid channel.
The fluid channel includes a diamond-shaped cross-section and includes a course from the at least one inlet to the at least one outlet over which the measuring fluid entering the fluid channel is deflected by at least 90° before the measuring fluid exits the fluid channel at the at least one outlet.

First claim

The invention claimed is:

1. A gas turbine engine, comprising:
a measuring device, comprising:
at least one fluid channel for conveying a measuring fluid, whereby the fluid channel comprises at least one inlet for entry of the measuring fluid into the fluid channel and at least one outlet for exit of the measuring fluid from the fluid channel,
wherein the fluid channel comprises a diamond-shaped cross-section and from the at least one inlet to the at least one outlet comprises a course over which the measuring fluid entering the fluid channel is deflected by at least 90° before the measuring fluid exits the fluid channel at the at least one outlet.

2. The gas turbine engine according to claim 1 , wherein the fluid channel contains at least one arc-shaped section.

3. The gas turbine engine according to claim 2 , wherein the at least one arc-shaped section has a bend angle of more than 30° for the deflection of the measuring fluid.

4. The gas turbine engine according to claim 3 , wherein the at least one arc-shaped section has a bend angle of more than 90° for the deflection of the measuring fluid.

5. The gas turbine engine according to claim 2 , wherein the at least one arc-shaped section includes a plurality of arc-shaped sections.

6. The gas turbine engine according to claim 5 , wherein the at least one arc-shaped section includes at least two arc-shaped sections, each with a bend angle of more than 90°.

7. The gas turbine engine according to claim 1 , wherein the fluid channel comprises an L-shaped or a Z-shaped course.

8. The pas turbine engine according to claim 1 , wherein the diamond-shaped cross-section is defined by a height and a width, and the height and/or the width are in the range of 0.4 mm to 3 mm.

9. The gas turbine engine according to claim 1 , wherein the fluid channel has a length of at least 50 mm.

10. The gas turbine engine according to claim 1 , wherein the at least one fluid channel includes a plurality of fluid channels configured for determination of different measurement data using the measuring fluid conveyed through the plurality of fluid channels.

11. The gas turbine engine according to claim 10 , and further comprising analysis electronics configured to determine measurement data using the measuring fluid conveyed through the at least one fluid channel.

12. The gas turbine engine according to claim 11 , wherein the analysis electronics are configured to determine measurement data using the measuring fluid conveyed through the plurality of fluid channels and to determine at least two different signals based on the measurement data.

13. The gas turbine engine according to claim 1 , wherein the measuring device comprises a body in which the at least one fluid channel and at least one cooling channel are provided.

14. The gas turbine engine according to claim 13 , wherein the at least one cool nq channel includes at least three cooling channels that are grouped around the at least one fluid channel in a cross-sectional view through the body.

15. An aircraft comprising:
a measuring device, comprising:
at least one fluid channel for conveying a measuring fluid, whereby the fluid channel comprises at least one inlet for entry of the measuring fluid into the fluid channel and at least one outlet for exit of the measuring fluid from the fluid channel,
wherein the fluid channel comprises a diamond-shaped cross-section and from the at least one inlet to the at least one outlet comprises a course over which the measuring fluid entering the fluid channel is deflected by at least 90° before the measuring fluid exits the fluid channel at the at least one outlet.

16. A measuring device for an engine, comprising:
at least one fluid channel for conveying a measuring fluid, whereby the fluid channel comprises at least one inlet for entry of the measuring fluid into the fluid channel and at least one outlet for exit of the measuring fluid from the fluid channel,
wherein the fluid channel comprises a diamond-shaped cross-section and from the at least one inlet to the at least one outlet comprises a course over which the measuring fluid entering the fluid channel is deflected by at least 90° before the measuring fluid exits the fluid channel at the at least one outlet; and
a body in which the at least one fluid channel and at least one cooling channel are provided.

17. The measuring device according to claim 16 , wherein the at least one cooling channel includes at least three cooling channels that are grouped around the at least one fluid channel in a cross-sectional view through the body.
