Airbus

Contactless Loudspeaker Array positioning system

Description of the company

Airbus is the largest aeronautics and space company in Europe, providing products, services and solutions for the commercial aircraft, helicopter, defense and space sectors. Drawing on over half a century of aerospace engineering expertise, Airbus products are defined by innovation. We are developing the next generation of aircraft to be lighter, safer and more fuel-efficient, and to fly using alternative fuel sources.
From the commercial aircraft and helicopters that connect and unite people around the world to the military aircraft and satellites that protect citizens and countries, Airbus products enable modern and connected life.

Situation

At the Acoustic Flight LAB a loudspeaker array consisting out of 2x 222 speakers serves as a source to reproduce in flight acoustic loads for future a/c configurations. (See Figure)

The loudspeaker array could be moved by electric motors translationally in circumferential direction and towards and away from the fuselage and it could be rotated. In order to perform noise measurements the loudspeaker array needs to be positioned precisely.

Problem

Today the positioning of the loudspeaker array is checked manually by a folding rule. This is especially at array positions high above the floor very difficult and imprecise.

Aims of the project

In the project a contactless measurement system for the loudspeaker array should be designed and developed. Therefore at least the distance between fuselage and the four corners of the speaker array should be measured and displayed to the operator of the loudspeaker array.

Scopes

Within the project a suitable sensor for contactless measuring the distance between loudspeaker array and fuselage should be selected and an appropriate design for attaching this sensor to the loudspeaker array should be developed. Furthermore the necessary hardware and software to display the distances to the operator should be selected and developed.
The mentioned hardware will be provided by Airbus to the students for the duration of the project.
