Vibroacoustic tests

We perform resonance tests of aircraft and other objects, also outside the aviation industry, in order to determine their dynamic properties. Based on the results of resonance tests, we perform numerical analyzes in the field of aeroelasticity, allowing to determine the velocities and flutter forms, in accordance with the requirements of aviation regulations. We perform vibration tests, acoustic tests and measurements of other quantities and parameters characterizing an operation, enabling the diagnosis of the condition of a machine, device, vehicle or aircraft in their operating conditions. We carry out tests commissioned by external Clients, our own research work and work carried out as part of projects conducted at the Institute.  The mobility of all elements of the laboratory equipment makes it possible to perform analyzes in a place agreed with the Customer.
