Aerospace: A Rugged and Portable Instrument Designed for your Environment

Whenever dealing with aerospace or defense crafts, a test is always costly and must be accomplished in a short time window. At the development stage of aircraft wing structures or satellites, measurements such as modal analysis, often based on multiple shaker excitation, must be successful the first time and data stored safely and securely.

Rotating Analysis

Jet & Rocket Engines Test

Propulsion safety is critical for the aero industry. The OROS analyzers record raw data and display the information you need for proper jet engine test. Thanks to the Synchronous Order Analysis, they compute the orders of jet engines during hours of tests required by the propulsion tests centers or flight/taxi tests. The integrated conditioners offer a wide range of transducer interface (ICP, Float, ±40 V, Strain gauges, Thermocouples, PT100, Oversampled tachs). With the data and control/command tool kit (NVDrive®) the analyzer is easy to integrate in the test benches.

 

Helicopter Transmissions

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 high speed torsional inputs.

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.

Structural Dynamic Analysis

Modal Analysis

Modal Analysis is one of the key steps when testing component prototypes: it determines their structural characteristics and so, defines how they reacts to operating excitations. Shaker or impact hammer excitations can
be used to capture the experimental datasets: the final stage is the actual OROS Modal analysis.

 

 

Structural Test

Spacecraft structures are checked with the large channels distributed systems (VibeMaster).  It measures simultaneously up to 500+ channels for one shot tests.

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.

Noise Analysis

Cabin Noise

Distributed systems allow recording hundreds of microphones located in aircraft passenger cabin, like identifying HVAC noises. Thanks to the swappable Mobi-Disks, the next test can be launched immediately. The real-time
acoustic
computation (Leq, 1/n Octave) monitors the measurements quality, while the recorder provides secured data. Locations with restricted area can be controlled wireless.

 

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 repeatable and standards compliant solution for testing noise emitted by aircraft sub-systems like air conditioning, fans and electric motors.
