In this initial design, a coupler and the radiators are placed above an integrated balancing unit (balun) so that a balun transforms terminal-fed dipole input impedance and impedance of a coupler. A ring power coupler is used for allowing feeding dipoles from different ports. So if it is done, then it is possible to form sum and difference radiation patterns (RP) in one integrated module so that it could be used when constructing more complex antenna systems.The realized isolation between sum and difference channels is better than -20 dB over 350 MHz frequency band. The frequency bands of the sum and difference channels overlap frequency band of a ring coupler.The proposed in the second section printed arrangement increases the frequency distance between the lower and higher working bands in comparison with the dual-band antenna on a base of classical center-fed dipoles which was described in Russian Patent no. 2 432 646 published 27.10.2011.The eight-element dipole antenna array, presented in the last section, comprise Butler matrix in order to form eight independent beams.","PeriodicalId":216376,"journal":{"name":"2019 20th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131091744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article analyzes the starting characteristics of an aircraft gas turbine engine, and draws up requirements for the design of electrical starting devices of an aircraft engine. A variant of building starter-generator system to increase the electrification level of the aircraft’s on-board equipment, as part of the implementation of the \"more electric aircraft\" concept is proposed. Along with the increase in the level of electrification, there is an urgent need to increase the energy efficiency of the existing electrical equipment of the aircraft. One of the criteria for the efficiency of use of the onboard equipment of the aircraft is the implementation of multipurpose use of the onboard components and assemblies. Within the framework of this criterion, it seems appropriate to combine the starter and the generator of the auxiliary power unit in one unit.","PeriodicalId":216376,"journal":{"name":"2019 20th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116482467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soft switching range can be significantly extended by adjusting conversion frequency according to the condition of ensuring the input current recuperation interval. The regulation range limit with ZVS is determined while limiting the maximum value of the transformer flux density. The performed calculations show that it is 65% of the full regulation range.

It is shown that the presence of bending oscillations of an ultrasonic radiator and gradient of sound pressure leads to the appearance of acoustic vortex flows in a resonant gap with a characteristic size equal to half the wavelength of acoustic oscillations. It has been established that the formation of acoustic vortices provides an increase in the concentration (more than 4 times) of dispersed particles in the immediate vicinity of the surface of the reflector, which contributes to an increase in the probability of their collision.

The radiometer functionality is based on the null method of measurement that ensures the invariance of measurements towards changes in the transmission factor and radiometer’s own noise. In the article we have described the newly developed hyperspectral microwave radiometer operation algorithm. The algorithm is based on synchronous amplitude and width pulse modulation that enables the equalization of the signal energy from the antenna in the microwave front-end of the radiometric system. Destabilizing factors in the operation of the developed microwave radiometric system for near-field measurements have been shown. The authors have described the mathematical model that takes into consideration the impact of the losses in passive front-end modules, the precision of thermostat control and the level of reflection coefficient on the measurement results. Based on the results of numeric modeling, it has been shown that to minimize measurement error down to ±0.1 K, equivalent front-end thermostat control precision and minimal losses in the front-end must be ensured and an antenna that allows for lowering the reflection coefficient down to 0.05 must be used.","PeriodicalId":216376,"journal":{"name":"2019 20th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126439434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
