Developer

Aug 2002 - Jun 2014 (11 years)

I developed a system of ignition for stationary internal combustion engines This design used on gas-producing enterprises. I have developed a telemetry system for strain measurement of aircraft engine blades. A new method was introduced for metrological certification of telemetry system. In this method we used Fourier transform and band spectrum. Cortex-M3 and Cyclone IV had used for these developments.

Developer

A new method for verification frequency response of dynamic strain amplifier used in strength tests.

We propose a new method for checking the frequency response of strain amplifier used in research and testing in the aerospace industry, in particular in the development of aircraft engines. The proposed method is characterized by versatility, extended frequency range, the ability to check the sensitivity of strain amplifier with an error of 0.1%, simplicity. The proposed method was tested in Motor Sich JSC. The proposed method can be the basis of a automatic test system of strain amplifier.
