LTT's robust and flexible measurement technology is ideally suited for use in the aerospace industry due to its high sampling rate and extremely accurate data acquisition
The measurement technology from Labortechnik Tasler impresses with its exceptionally high precision. For this reason, our measurement data acquisition devices can also be used in the following areas of the aerospace industry:
Material testing is one of the most critical disciplines in the aerospace industry. Components in airplanes, helicopters, and spacecraft are subjected to extreme mechanical, thermal, and dynamic stresses during operation. Since even the smallest material defects or undetected signs of fatigue can have catastrophic consequences, comprehensive and extremely reliable testing is essential. These tests guarantee compliance with the highest safety standards and ensure that modern, weight-optimized materials can withstand the harsh conditions of daily flight operations over the long term.
This is where NVH (Noise, Vibration, Harshness) analysis comes into play. This method systematically examines the vibration, noise, and harshness behavior of materials, structures, and powertrains. In materials testing, NVH analysis helps identify acoustic anomalies, unwanted resonances, and structural stress limits at an early stage. Since vibrations and noise emissions are often the first symptoms of material fatigue or structural weaknesses, this approach allows for the detection of impending defects before they become a safety concern.
To reliably capture these high-frequency dynamics and transient phenomena, high-precision real-time measurements are absolutely essential. The physical behavior under real-world conditions occurs in a fraction of a second: Even the slightest measurement inaccuracies, noise components, or phase shifts can cause critical resonance points or load peaks to be overlooked. Only latency-free real-time acquisition with extremely high sampling rates ensures that even the slightest changes in vibration behavior are documented and analyzed with absolutely no distortion.
The LTTsmart (which serves, among other things, as a high-precision power analyzer and multichannel data acquisition system) has established itself as the ideal measurement system for such high-end applications. With state-of-the-art 24-bit A/D converters, sampling rates of up to 4 MHz per channel, and outstanding measurement accuracy, it delivers extremely low-noise and highly synchronized results. Thanks to its modular flexibility—with combinable inputs for sensor technologies such as ICP/IEPE, strain gauges, or charge—full galvanic isolation, and robust construction, the LTTsmart handles even the most demanding test bench and field applications in the aviation industry, such as material and vibration tests on gas turbine blades or electric drives.
“KRP-Mechatec collaborated with the Max Planck Institute in Garching on certain measurements. On this occasion, measurement data was recorded in parallel with the MPI's measurement systems using the LTT measuring devices. The comparison showed that the LTT measuring devices delivered extremely accurate measured values!”
