MAIN MENU

As turbine architectures become more efficient, lightweight, and thermally stressed, the need to validate performance under rapidly changing thermal and dynamic environments has never been greater. Modern gas‑turbine test campaigns must capture high‑temperature vibration, pressure pulsations, and dynamic structural behaviour in real time to ensure engine reliability and durability.

These measurements support critical activities such as blade dynamics validation, bearing and rotor assessment, and the development of Health and Usage Monitoring Systems (HUMS) and condition‑based maintenance strategies - while operating within tight test schedules and highly instrumented facilities.

HBK’s gas‑turbine test systems integrate seamlessly with high‑temperature sensing technologies - including accelerometers, pressure sensors, and strain instrumentation -and provide a robust framework for synchronized data acquisition, real‑time validation, and advanced post‑analysis across the full engine operating envelope.

Gas turbine testing system overview

System Suggestion

This LAN XI based system  provides reliable data recording for hundreds of dynamic channels, highly detailed real time monitoring, and efficient sharing of test data for post test analysis. Integrated real time analysis and alarm functions help ensure data validity, even in high temperature environments where vibration characteristics, pressure behaviour, and strain responses can shift rapidly.

Highly scalable and easily transportable, the system can be configured as a high capacity centralized data acquisition platform or distributed into smaller mobile systems. Its modular architecture supports engine stand testing, subsystem validation, and distributed measurement campaigns supporting HUMS and condition monitoring development.

BK Connect software provides powerful post analysis capabilities, supporting a wide range of native and third party data formats. Engineers can correlate high temperature vibration, pressure, and strain measurements with operating conditions to gain a comprehensive understanding of turbine structural and dynamic health.
