3 core test scenarios
1. Aircraft Structural Testing
Perform static loading and fatigue testing on primary load-bearing structures such as the fuselage, wings, and tail. Synchronously collect data from hundreds of strain gauge channels to monitor structural deformation and stress distribution in real time. The system supports a sampling rate of 512kS/s to precisely capture transient signals associated with crack initiation and propagation. Integrated with Digital Image Correlation (DIC) technology for full-field strain measurement and validation.
2. Advance system testing
Collects key parameters such as speed, thrust, fuel flow, exhaust temperature, and vibration during engine test bench trials. High-frequency response captures unstable phenomena like surge and rotating stall, providing data support for optimizing engine control laws. Heat-resistant sensors and insulation designs accommodate the high-temperature environment of the engine compartment.
3. In-flight testing
A lightweight data acquisition unit mounts directly inside the aircraft to record aerodynamic loads, structural responses, and system status during flight. It supports IRIG-B timecode synchronization with flight recorders for post-flight data correlation. Redundant storage and power-loss protection ensure test flight data integrity.

Static test of a commercial aircraft main wing
Leading domestic commercial aircraft manufacturer
The new wide-body aircraft's main wing requires an ultimate load static test to verify structural strength and design margins. The test involves over 300 loading points and more than 500 strain measurement channels, with all channels requiring a synchronization error of less than 200 ns.
The FIDES Q series rack-mounted acquisition system uses 8 cascaded chassis to achieve synchronized data collection across 512 channels. IEEE 1588 PTP protocol ensures nanosecond-level synchronization accuracy, while redundant storage mechanisms safeguard test data integrity. SeeDeria software displays real-time strain contour maps to assist in monitoring the loading process.
