Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

Wind Tunnel Acoustic Testing – Aerospace

Reduction of noise emissions is a critical technology for aircraft manufacturers and various analytical, empirical and numerical tools exist to help in the design of quieter aircraft.

Given the complexity of the noise source mechanisms, wind tunnels are used for aeroacoustic measurements of aircraft noise sources and their directivities; both for validating prediction methods and for investigating the acoustic impact of noise-reduction treatments. Both open-circuit, anechoic wind tunnels, and closed-circuit wind tunnels are used for aerodynamic and aeroacoustic studies of various flow-induced noise phenomena. The choice of test facility is driven primarily by the type of application, the design speed, and the desired model scale.

System suggestion

Brüel & Kjær’s Wind Tunnel Acoustic Test System accurately performs all the tasks needed for aircraft acoustic scale-model testing. The system is based on our standard, commercial-off-the-shelf (COTS) products that are optimized for the specific issues faced with wind tunnel test applications. They cover the entire measurement chain of transducer, data acquisition, analysis and reporting.

A system typically consists of the necessary number of microphones, preamplifiers, LAN-XI data acquisition hardware, an acquisition workstation installed with relevant software, PTP (Precision Time Protocol) enabled LAN and one or more remote monitoring stations.
