Abstract

A velocity mapping system comprising a sensor system and an airflow mapper. The sensor system is configured to generate data about a velocity of airflow for a location in a duct system. The airflow mapper is configured to receive the data from the sensor system and generate a profile of the velocity of the airflow at the location in the duct system.

First claim

What is claimed is:

1. A velocity mapping system comprising:
a sensor system configured to generate data about a velocity of airflow for a location in a duct system, wherein the sensor system comprises a sensor array having one or more sensors and a frame that has a shape that corresponds and conforms to a shape of a cross section of the duct system in the location where the sensor array is placed;
an airflow mapper configured to receive the data from the sensor system and generate a profile of the velocity of the airflow at the location in the duct system; and
an air source configured to be connected to an input end of the duct system and generate the airflow in the duct system;
wherein the profile comprises a number of sets of data for different points in space and time, in which a set of data in the number of sets of data represents one or more velocities of airflow found across the cross section of the duct system for a point in time;
wherein the data is for portions of the cross section of the duct system at the location and the airflow mapper is configured to interpolate the data for the portions of the cross section to generate data for missing portions of the cross section of the duct system;
wherein the sensor system measures values for velocity of airflow across the cross section of the duct system;
wherein the sensor system generates the data that is only for the portions in the cross section of the duct system;
wherein the airflow mapper is configured to graphically indicate velocity of airflow for the cross section by displaying the profile on a display system in a form of a map;
wherein the map graphically indicates the velocity of the airflow for the cross section of the duct system in the location;
wherein display of the velocity for the cross section of the duct system in the map changes as the velocity changes in different sets of data in the sets of data, and
wherein the profile comprising the number of sets of data representing the one or more velocities of the airflow found across the cross section of the duct system for different points in space and time is saved in a duct velocity profile database of profiles for different duct systems, whereby the profiles of duct systems generated by the velocity mapping system may be used in maintenance and service of an air distribution system in an aircraft.

2. The velocity mapping system of claim 1 , wherein the airflow mapper is configured to update the profile as the data about the velocity of the airflow changes.

3. The velocity mapping system of claim 2 , wherein each update of the profile forms a new set of data in the number of sets of data in the profile.

4. The velocity mapping system of claim 1 , wherein the profile comprises data points in which a data point in the data points is a percentage of a maximum air velocity.

5. The velocity mapping system of claim 1 , wherein the airflow generated by the air source has a known flow rate.

6. The velocity mapping system of claim 1 , wherein the airflow mapper comprises:
a processor unit;
a storage device; and
program code stored on the storage device, wherein the processor unit is configured to run the program code to receive the data from the sensor system and generate the profile of the velocity of the airflow at the location in the duct system.

7. A method for analyzing airflow in a duct system, the method comprising:
generating, via a sensor system, data about a velocity of the airflow for a location in the duct system, wherein the sensor system comprises a sensor array having one or more sensors and a frame that has a shape that corresponds and conforms to a shape of a cross section of the duct system in the location where the sensor array is placed; and
generating a profile of the velocity of the airflow at the location;
wherein an air source connected to an input end of the duct system generates the airflow in the duct system;
wherein the profile comprises a number of sets of data for different points in space and time, in which a set of data in the number of sets of data represents one or more velocities of airflow found across the cross section of the duct system for a point in time;
wherein the data is for portions of the cross section of the duct system at the location and an airflow mapper is configured to interpolate the data of the portions of the cross section to generate data for missing portions of the cross section of the duct system;
wherein the sensor system measures values for velocity of airflow across the cross section of the duct system;
wherein the sensor system generates the data that is only for the portions in the cross section of the duct system;
wherein the airflow mapper is configured to graphically indicate velocity of airflow for the cross section by displaying the profile on a display system in a form of a map;
wherein the map graphically indicates the velocity of the airflow for the cross section of the duct system in the location;
wherein display of the velocity for the cross section of the duct system in the map changes as the velocity changes in different sets of data in the sets of data; and
wherein the profile comprising the number of sets of data representing the one or more velocities of the airflow found across the cross section of the duct system for different points in space and time is saved in a duct velocity profile database of profiles for different duct systems, whereby the profiles of duct systems generated by the velocity mapping system may be used in maintenance and service of an air distribution system in an aircraft.

8. The method of claim 7 further comprising:
updating the profile as the data about the velocity of the airflow changes.
