For the first time in Ukraine a prototype of the "point-to-point" wireless communication system in terahertz frequency band of 130-132 GHz was developed with usage of impulse ultra wideband signals for local computer networks and sensors data transmission networks which based on the proposed “non-energy” reception method of impulse ultra wideband signals.
Design and technological classification of standard blades of modern gas turbine engines is developed. Selected typical elements of solid and hollow blades for which tasks are set for the development of manufacturing technologies.
The work is aimed at creation of high-efficiency heat regenerators of gas turbine units (GTU) of the gas transportation system of Ukraine. It is proposed to use highly effective heat exchange surfaces from the tubes of the spiral corrugated profile with high heat and aerodynamic characteristics for heat regenerators GTU, which will ensure a reduction of mass-dimensions by 30- 40% in comparison with heat exchangers made of smooth round tubes and an increase in the KPD GTU from 18-25% to 38-41%.
