• DOMINANT TECHNOLOGIES IN “INDUSTRY 4.0”

    WAVELET ANALYSIS OF ACOUSTIC SIGNALS

    Industry 4.0, Vol. 3 (2018), Issue 3, pg(s) 138-140

    In modern warfare there has been increased use of various weapon systems like tanks, artillery, mortars, infantry armored vehicles, multiple launch rocket system (MLRS). Hostilities often are conducted in densely populated urban areas, where most victims are given by the civilian population. It is the application of systems of detection and reconnaissance sources of sound (the weapons), and also the quick disclosure of their locations. It achieves a “rapid response” of the threats and reduces casualties. Wavelet analysis offers a quick way to process acoustic signals received in the shooting which provides the opportunity for quick reconnaissance and defining sources of sound.

    AN EXPERIMENTAL INVESTIGATION OF THE 122mm ARTILLERY SYSTEM FIRING ACOUSTIC FIELD

    Security & Future, Vol. 1 (2017), Issue 4, pg(s) 160-162

    In the recent years, the battlefield acoustic exploration acquires a new dimension. This is due to the fact that modern weapons have a significantly increased distance of defeat, but the intelligence cannot detect such weapons at a sufficiently distance. In this connection the purpose of the present study is to investigate the near acoustic field of 122 mm artillery system firing. The collected with advanced technology equipment raw data were analyzed with the harmonic and wavelet analysis tools.

  • EVOLUTION OF HYDRODYNAMIC CAVITATOR

    Mechanization in Agriculture, Vol. 61 (2015), Issue 2, pg(s) 17-20

    The original design of a cavitator is a volute (snail) with a tangential inlet connected to the pump and an axial outlet which is attached to the body in the form of a cylindrical tube, which ends with a braking device and a central hole connected to inlet of the pump.
    Proposal: 1) to equip cavitator with axial gas extractors in the volute (snail) and at the output from the body, 2) exclude the snail (volute) from the construction and control the interaction of flows by dividing stream leaving the pump into two parts and then merge them in the camera in front of body, 3) organize an axial jet in body with the required structure by using ring nozzles, 4) reduce a vortex component of the current by installing a second straightening snail (scroll) before the body, 5) design the pump as an active generator of elastic vibrations of useful frequencies while maintaining its primary function; – separate it with antivibration bushing.
