Category : Press Release , Z-DAMPER

Z-DAMPER has been awarded the first price from 22 nominated Clean Sky projects as best example of successfully performed activities.



 CLEAN SKY is the largest research program funded by the EU Commission developing advanced technologies designed to significantly reduce C02 and NOx emission and noise levels. This week, the Clean Sky 1 Closing Event “Europe, Innovation, and Aviation: Are we keeping up?” was celebrated in order to report results and main achievements, pushed forward by a successful collaboration between private and public actors.

Z-Damper, awarded the 1st prize, is a clear example of successful collaboration between the high-tech engineering small company MAG SOAR, as project coordinator, and Universidad de Alcalá. Z-Damper has created and demonstrated a disruptive vibration killer technology with an optimum performance at extreme temperature.   

Main goals of Clean Sky are the developments of new efficient and clean aircraft engines. A key challenge was to damp effectively their vibrations and a new enabling vibration isolation technology was required. Z-DAMPER has developed a solution from the concept up to the experimental tests, including design, engineering, simulation, manufacturing of prototypes and a testbench for demonstration from -70 to 300 ºC. This acknowledgment underlines the potential of Z-DAMPER as a promising vibration isolation technology, not only for aerospace but also for industry, antiseismic, large structures and other defence applications.

CLEAN SKY is right now the largest European research H2020 funded program developing innovative, cutting-edge technology aimed at reducing C02, gas emission and noise level produced by aircraft.  This nomination confirms the big potential of Z-DAMPER for the control of vibrations at high temperatures and low frequencies.

Z-Damper is a magneto mechanism that matches mechanical impedances and provides a multiplier effect damping vibrations of both low and high frequency ranges more effectively.

Z-Damper optimum performance at extreme environments made this magneto-mechanism the perfect vibration killer to be used in one of Clean Sky major projects: the new counter-rotating open-rotor (CROR) developed by Airbus. CROR fuselage-mounted turbofans need a level of isolation of vibrations in a high-temperature environment that current damping technologies are not able to reach.

MAG SOAR SL, in cooperation with Universidad de Alcalá, developed and tested two prototypes following Airbus requirements. "Z-Damper has demonstrated a unique damping performance, even in extreme temperature environments. We have insight the birth of a new vibration isolation technology which applications are only starting to be foreseen", stated Dr. Valiente, technical director of MAG SOAR and scientific responsible of the project.

Z-Damper: A new technology for vibration control at extreme temperatures

Madrid-18/07/2016-MAG SOAR in collaboration with UAH develops a completely innovative system to face vibration problems by mechanical impedance matching

 Vibration control of buildings, airplanes, cars and other kinds of systems and structures is an extremely important issue in constant evolution. Insufficient control of vibration propagation can cause the critical failure and ultimately, the total breakage of an structure. Devastated buildings after earthquakes are extreme examples of the consequences of out of control vibrations.

There are different forms to reduce, mitigate or suppress vibrations. The simplest way is to increase the elasticity of the ground connections between a moving machine and a stable surface. Multiple solutions have been developed with this purpose that go from elastic couplings to floating benches. All of them can provide a quite a good vibration isolation with an appropriate design. However, these are limited to normal temperature and relatively high frequencies. Moreover, these solutions usually involve a significative increment of weight.

MAG SOAR engineers have just designed a new vibration control technology able to handle extreme temperature conditions at low and high frequencies thanks to mechanical impedance coupling. Z-DAMPER is a zero-backlash magneto-mechanism that has been optimized for matching mechanical impedances in order to control vibration propagation in a structure. This is the first damping technology to reach temperatures as high as 250 ˚C and as low as -200 ˚C and able to cope with high dynamic forces. Besides, there is not contact between the movable members so it barely needs maintenance. All of this makes Z-Damper the perfect candidate for extreme temperature environments where lubrication and wear related problems can have catastrophic consequences.

Z-DAMPER can also be applied to enhance the efficiency of other damping systems, like tuned vibration absorbers, eddy-current dampers and particularly, those with a poor performance at low frequency vibrations. The working principle detailed in the recently published paper, “Z-Damper: a new paradigm for attenuation of vibrations”
