See what moves when aeroacoustic noise appears
QSeries Laser RADAR gives aeroacoustics teams a clear view of structural motion in wind tunnels and operating rigs. Measure geometry and vibration across many points at once, then link the response to the sound, flow condition and design decision in front of you.
Explore acoustics, noise and vibration measurement.

Turn aeroelastic data into a confident next step
Aeroelastic performance comes down to what the structure does under load. Map mode shapes and response across the test article, compare them with the model, and see where stiffness, damping or boundary conditions need attention before the next campaign.
Road-vehicle wind tunnels: find the path behind wind noise
Automotive wind noise rarely comes from one feature alone. Mirror and A-pillar flow, wheelhouse excitation, glazing and door seals all influence the cabin. Acoustic arrays show where noise starts; cabin microphones show what occupants hear. QSeries shows how the body side, glazing or trim is responding.
See which change will move the result
Measure side glass, upper door, roof rail and body-side panels while the wind-tunnel condition reproduces the issue. Compare mirror, seal, glazing and trim variants with the same spatial evidence, then align the result with CFD, CAA and acoustic data.
For wider vehicle-development work, explore Automotive NVH vibrometry. Published wind-tunnel studies of side-mirror source identification and A-pillar, side-glass and interior transmission offer useful technical context.

Answer the question behind the noise
When the result could be a flow source, a structural mode or a transmission path, a spatial vibration map tells you where to look next.
Find the mode behind the tone
See the surface pattern behind a narrow-band tone, resonance or forced response.
Follow flow-induced vibration
Show where unsteady flow is driving a panel, blade, fairing, duct or casing.
Bring model and test together
Compare measured mode shapes and operating response with CFD, CAA and aeroelastic predictions.
Test the condition that matters
Capture structural response at the speed, flow setting or operating point that drives the decision.
Find the structural path in fan and duct noise
Fan and propulsor noise can travel through the rotor, stator, duct, casing, mounts and surrounding panels. QSeries maps the response around the rig so your team can pinpoint local modes and transmission paths alongside microphone, pressure and performance data.
Use that view to prioritise the next geometry, damping, mounting or acoustic-treatment change.
Use the right signal for the decision
Strong aeroacoustic test programmes connect flow loading, sound and structural response. QSeries gives the structural view that completes the picture.
What is heard
Measure level, spectrum and source correlation at the observer or array location.
What is loading the surface
Capture local pressure fluctuation and flow-driven excitation where the load is in question.
Trusted motion at selected points
Use them as reference channels on known critical components.
Where the structure is responding
Map geometry and vibration across many points in parallel, so the active surface or mode is clear.
Bring structural motion into the aeroacoustic test
See how Laser RADAR turns an aeroacoustic test article into a spatial measurement target. Apply the same workflow to connect structural motion with acoustic and flow data.
From noise result to design action
Bring the vibration map together with microphone data, pressure measurements and the operating condition. Then decide whether the next change belongs in the surface, structure, mounting or treatment.

Aeroacoustics and flow-induced-vibration questions, answered
QSeries measures geometry and vibration across many points in parallel. Use it to map the structural response of wings, blades, panels, ducts, casings and other aeroacoustic test articles.
Yes. Measure the surface or load path during the operating condition that matters, then see where unsteady flow is driving the structural response.
Yes. Compare measured frequencies, mode shapes and operating response with the aeroelastic model, then refine the structural, boundary-condition or damping assumptions that matter.
Yes. A QSeries campaign is planned around optical access, the test section, the flow condition and the surfaces you need to understand.
Yes. Map accessible casings, ducts, mounts and nearby panels alongside microphone and pressure data to identify the structural path that needs attention.
No. Microphones show the acoustic outcome and pressure sensors show the loading. Laser RADAR shows how the structure responds, giving the team a complete diagnostic view.
Yes. Use spatial response maps to study blade dynamics, mode shapes and aeroelastic behaviour in the laboratory or another suitable test environment.
Flow-driven response often extends across a surface. Parallel multi-point measurement makes the active shape and location clear, rather than relying on a short list of sensor locations.
Laser Doppler vibrometry provides velocity and vibration information. QSeries brings that capability together with geometry measurement and parallel multi-point acquisition.
Bring the test article, operating condition, suspected noise or vibration feature, available access, expected frequency range and any acoustic, pressure or model data. That is enough to define a useful starting route.
Yes. In a road-vehicle wind tunnel, use QSeries to map accessible glazing, body-side panels, roof structures and other surfaces while the condition reproduces the wind-noise issue.
Acoustic arrays locate exterior source regions and cabin microphones quantify the result. QSeries maps the structural response of the surfaces between source and receiver, helping you choose between a flow, glazing, seal, trim or body-side intervention.
Start where the complaint and source evidence point: A-pillar and side-glass regions, mirror interfaces, upper door and roof-rail structures, wheelhouse-adjacent panels, glazing and door-seal interfaces.
