Dynalya and its partners were selected in 2013 during the "Helicopter of the Future" call for projects launched by Airbus Helicopters for the complete development of a highly efficient vibration filtration system.
After 4 years of development, flight tests have shown that the system developed allows to reach on a helicopter the comfort of a commercial airliner i.e. more efficient than all active or passive systems developed so far in the world.
The system was certified by EASA in October 2017.
Dynalya has developed for its customer Airbus Helicopters a low volume multi-axis camera suspension consisting of a ball and socket system.
The particularity of this suspension is that the stiffness can be modified axis by axis in order to set the resonance frequencies in the XYZ axes of the machine.
Dynalya has developed a connecting rod suspension allowing to totally cancel the transmission of an axial vibration in a connecting rod on a given frequency.
The system is based on an inertial amplification resonator integrated inside a ring serving as stiffness.
Dynalya has integrated on behalf of CETIM a system for measuring stresses and cracks by X-ray on a 5-axis robot.
In collaboration with MRX LABO, an expert in X-ray tube design, we designed the emitter tube as well as the entire sensor integration environment.
For the development of the Helicopter of the Future project, Dynalya has designed and built a vibrating table allowing to recreate faithfully the vibratory environment of a helicopter in the 3 axes at a cost significantly lower than industrial tables.
For this purpose we have developed innovative unbalance generators allowing to generate vibrations in one direction with a level independent of the rotation speed of the flyweights, i.e. to reproduce the operation of a vibrating pot for a price 10 times lower.
Our customer Airbus Helicopters entrusted us with the realization of an acoustic bench for standardized tests of heating duct transmission.
The unit consists of several sections mixing CNC machined aluminium parts and 3D printing parts made in-house, including high sensitivity microphones. The modular design of the assembly allows to regularly add new functionalities.
Dynalya has designed for the Sebraf company a machine for the projection of green waste in bulk or in bundles.
Several problems have been solved by simple but very robust solutions to adapt to all the required configurations.
For example, a kinematic study combined with a stress study allowed to optimize the external conveyor belt so that it tilts in different positions with a minimum of effort for the operator.
