Rotating Analysis

Jet Engines Test

Propulsion safety is critical for the aero industry. The OROS analyzers, thanks to their Recorder, allow collecting raw data and acquiring the orders, with the Synchronous order analysis, of jet engines during hours of tests required by the propulsion tests centers.
The data and control/command toolkits (NVDrive) make the analyzer easy to integrate in the test benches.

Helicopter transmissions

The multi-shaft order analysis provides synchronous order extraction form the helix and the turbine.
Vibrations related to gears are extracted with the FFT-Diagnostics tool.
Absolute and relative torsional motions are acquired and analyzed with the integrated frequency to voltage converter.

Noise Analysis

Cabin Noise

Large channels distributed systems (VibeMaster) allow recording hundred of microphones located in large aircraft passenger cabin.
Thanks to the swappable Mobi-Disks, next test can be launched immediately.
Real-time acoustics monitoring (Leq, 1/n Octave) help checking the measurements quality, while the Recorder provides secured data.
To reach difficult places in the aircraft, a SmartRouter (controller unit) is used with its wireless capabilities.

Sound Power

The OROS Sound Power software module acquires simultaneously up to 21 microphone’s locations signals, reducing dramatically the measurement time of aircrafts and helicopters jet engines.
With a Class 1 type results, it fulfills acoustics test benches requirements.
OROS Sound Power offers a reproducible and standards compliant solution for testing noise emitted by aircraft sub-systems like air conditioning, fans and electric motors.

Structural Dynamic Analysis

Modal Analysis

The OROS analyzers offer a comprehensive toolset for modal analysis on components, sub-systems and pipes.
The sequencer guide indicates nodes and direction during the FRF’s acquisition.
OROS Modal 2 software module identifies natural frequencies from broadband signals and shows the relative motion on 3D graphs.

Structural Test

Spacecraft structures are checked with the large channels distributed systems (VibeMaster). It measures up to 320 channels simultaneously for one shot test.
From shaker or loudspeaker excitation the FFT, 1/n Octave and swept-sine offer real-time monitoring and provide immediate results and raw data making the test conclusions faster.

Data Acquisition

In-Flight Recording

The different components installed in a aircraft are tested in-flight to validate their integration. It requires a portable, rugged and easy recording system. PC free recording is especially very useful for the toughest conditions (D-rec, Direct Recording)

Fatigue Test

The XPod plug and play bridge conditioner measures dynamic strain for life duration analysis of critical parts like aircraft body , engine blades or wings fixtures.
The removable conditioner can remain connected to the strain, reducing cabling time.
