The possibility of using terrestrial television (TV) broadcast signals (TVBS) as sounding signals for mesosphere-lower thermosphere (MLT, 80–105 km) wind measurements by the radio meteor method is investigated. Results of experimental observations show for the first time that TVBS can be used for MLT wind measurements and that the developed technique may be used for MLT wind monitoring on the base...
Reviewed are the results of complex dynamic characteristics research of the natural gas centrifugal blower rotor, installed on tilting-pad and elliptical bearing. The results of calculated and experimental research are compared. The peculiarities of tilting-pad bearing properties are explained. Based on the received results the algorithm of diagnostics of the tilting-pad bearing is given.
Use of an accessible radiofrequency resource as an emitted television-broadcasting signal in the spaced radar system of meteoric traces for measurement of dynamic parameters mesopause-lower thermosphere is offered in this work. Experimental results of registration of television signals reflected by meteoric traces on a Moscow-Kharkiv line are submitted
