Wind tunnel, Hopkinson bar, PDV and avionics specialty tests

For specialty testing in wind tunnels, Hopkinson bars, PDV velocity interferometry and avionics systems — high-bandwidth, high-dynamic and high-synchronisation acquisition and analysis solutions.

  • Cutting-edge, specialised test subjects: wind tunnels, Hopkinson bars, PDV and avionics are specialty tests at the research and model-development stage, lacking mature reference samples.

  • High signal bandwidth: dynamic mechanics, detonation, shock waves and velocity interferometry often contain MHz-level frequency components, demanding stringent bandwidth and dynamic range.

  • Strict multi-channel synchronisation: waveforms from multiple points must be aligned on a sub-microsecond time base for waveform reconstruction and velocity inversion.

  • Non-repeatable single tests: wind-tunnel runs, Hopkinson bars and detonation tests are costly and non-repeatable, demanding high trigger reliability and data integrity.

  • Widely varying conditions: from subsonic to supersonic, static load to high-speed impact, airborne to ground — the span is large with many customisation needs, often requiring on-site adaptation.

System architecture

Wind tunnel testing
Wind tunnel test chain: pressure and vibration sensors on the wind tunnel model feed a GUXI Series fully domestic multi-function modular measurement & control instrument, and iMS View Virtual Instrument Software provides live waveform monitoring, spectrum analysis and test reports.
Hopkinson bar
Hopkinson bar test chain: strain gauges and accelerometers on the Hopkinson bar feed a PVIB2.0 Bus Series multi-channel modular measurement & control instrument, and iMS View Virtual Instrument Software performs stress-strain waveform reconstruction and dynamic mechanical property inversion.
PDV velocimetry
PDV velocimetry chain: the PDV optical interferometer and photodetector feed the Photonic Doppler Velocimetry (PDV) Flyer Velocity Test System, and iMS View Virtual Instrument Software generates velocity-time curves, integrates displacement and inverts shock waves.
Avionics testing
Avionics test chain: bus interfaces and environmental sensors on avionics equipment feed a GUXI Series fully domestic multi-function modular measurement & control instrument, and iMS View Virtual Instrument Software provides avionics parameter monitoring, EMC recording and airworthiness data output.
