Brüel & Kjær has been selected by Dassault Aviation to provide high-pressure surface microphones for the development of the nEUROn experimental Unmanned Combat Air Vehicle (UCAV).

Led by France's Dassault Aviation, the nEUROn is an experimental UCAV demonstrator being developed with the international cooperation of six European countries. Dassault chose Brüel & Kjær to supply high-pressure versions of their surface microphones to conduct flight test measurements.

Surface microphones provide information about the true pressure load on components during flight. The microphones are typically flush-mounted on flat and curved surfaces, for example on aircraft fuselages. They must be capable of withstanding both high pressures and the harsh environments experienced during in-flight measurements. Importantly, the microphones must be able to perform in the presence of high velocity airflow, whilst producing minimal wind-generated noise.
