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 ight/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.

It requires a portable, rugged and easy recording system. PC free recording is especially very useful for the toughest conditions (direct recording, distributed systems) Fatigue Test On-Site Measurements & Applied Trainings > Easy integration with our complete control/command tool kit (NVDrive) Experts from OROS come on-site for applied trainings. They will help you using your OROS system. They can provide assistance in your measurement. They are also able to recommend optimization in your measurement process depending on your application and eld requirements. > “My team’s job is to provide reliable and accurate data from various aircraft and conditions. The OROS Teamwork instruments serve our tests and analysis needs perfectly. Their exchangeable conditioners & disks, cascadable units and flexible software licensing make our every day job simpler and faster.” Vibration Program Manager, Rotor & Fixed Wing / In-ight Test Center. 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. Jet Engine Sound Power Sub-systems > Stand alone long duration recording with auto power management They trust OROS The XPod plug and play bridge conditioner measures dynamic strain and temperatures for life duration analysis of critical parts such as the aircraft body, engine blades or wings xtures. The removable conditioner can remain connected to the strain/thermocouples, reducing cabling time. > ICP, 200V polarized, oat/AC/DC/TEDS inputs > Wide range of export formats (Mat, ASAM, UFF, Txt, SDF, Wav…) Spacecraft structures are checked with the large channel 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. > Thermocouples/RTDs and strain gauges integrated conditioners > Satellite & antenna transportation survey Modal Analysis is one of the key steps when testing component prototypes: it determines their structural characteristics and so, denes how they reacts to operating excitations. Shaker or impact hammer excitations can be used to capture the experimental datasets: the nal stage is the actual OROS Modal analysis. Modal Analysis Structures Test Helicopter Transmissions Multi-shaft order analysis provides synchronous order extraction from the rotor and the turbine. Vibrations related to gears are extracted with the FFTDiagnostics tool. Absolute and relative torsional motions are acquired and analyzed with the integrated high speed torsional inputs. Structural Dynamics > Coupling parts > Transmission > Power Generation The OROS Sound Power software module simultaneously acquires up to 21 microphone’s locations signals, reducing dramatically the measurement time of aircraft and helicopter jet engines. With a Class 1 type results, it fullls acoustics test benches requirements. OROS Sound Power offers a repeatable and standards compliant solution for testing noise emitted by aircraft sub-systems such as air conditioning, fans and electric motors.
