The most important research stage of operational helicopter modal testing is successfully completed. The modal properties of both fixed and rotating helicopter structures are identified in both frequency and shape domains. The resolution capabilities of advance vibration diagnostic are determined. The system applying the novel “modal passport” approach is able for detection the local failures both fixed and rotating structures of operating helicopter without shutdown.

Initial stage of research works is conducted to estimate the potential economic effect of vibration diagnostic techniques application in technical maintenance of aircrafts. At the same time the research works are going to optimize the scale of seeded faults required for more convincing demonstration of advanced system capabilities of actual failures detection on the operating helicopter.
9th April 2020
In the 1st quarter of 2020 the set of multichannel equipment for testing control and management has been delivered and assembled on board of the helicopter. The system has been tested and prepared for research study works on operational helicopter.
6th January 2020
To the end of 2019 the onboard measurement system has been assembled on the helicopter. Multichannel DAU, remote control switchers and data transmitting equipment has been tested and prepared for laboratory research study stage.
3rd October 2019
Within frames of the research study “Demonstrator of Aircraft Perspective Vibration Diagnostic Technology Complex” in 3rd quarter of 2019 have been completed assembling and testing works. Also FE modelling and computation works are made for helicopter natural modes identification.

D un D centrs launches a study inside project No.18.104.22.168 / 18 / A / 001 within the Energy and Transport Competence Center. The smart specialization chosen by the ETCC is smart energy, which includes three research sub-themes: Smart Energy General Issues; Intelligent engineering systems and power generation solutions; Smart energy and transport. The project is being implemented from April 1, 2019 until December 31, 2021. The total amount of ERDF support for the project is EUR 4 708 111.50.
Our study is No. 4 “Demonstrator of Aircraft Perspective Vibration Diagnostic Technology Complex”. The purpose of the study is to realize the stand on which the development of vibration diagnostics technologies can be performed on any type of aircraft. This stand is also needed for demonstration and promotion of new technologies. The study is being implemented from 1 April 2019 to 30June 2021.
In partnership with Aviation Research Center D un D centrs has finished a research with a sounding name – “Study of aircraft engine components dynamic properties for engines vibrodiagnostic technology research and complex demonstrator development”. The goal of this project was to implement engine diagnostics technology on a special rig and demonstrate effectiveness of such technology. D un D centrs has provided scientific base for this project and shared its experience in engine vibrodiagnostics. Read more about the project at Aviation Research Center website.
D un D centrs has started a research Nr. 18 "Study of planetary gearbox dynamic properties for vibrodiagnostic technology research and demonstrator development" within Smart Engineering System, Transport and Energy ICC project (SESTE ICC). This research will provide a one of a kind planetary gearbox vibrodiagnostics technology, which is to be experimentally validated and verified. This is another step in vibrational diagnostics field.
