dc.description.abstractPagal ICAO nuostatas (AERODROME METEOROLOGICAL OBSERVING SYSTEMS STUDY GROUP (AMOSSG) Agenda Item 5. Chapter 4 to Annex 3)oro uoste turi būti vėjo greičio matuokliai, jie turi greitai ir tiksliai matuoti oro masės srauto greitį, tą informaciją perduodama į oro uosto valdymo centrą. Labai keičiantis oro srautų greičių diapazonui ir matavimo sąlygoms, reikia kurti ir tirti naujus srautų matavimo metodus, diegti adaptyvias srautų greičio matavimo sistemas. Šiame tyrime buvo sukurti ultragarsinę dujų srautų greičio matavimo sistemą, ištirtos eksperimentinės paklaidos. Eksperimentinės paklaidos yra atvaizduojamos grafikuose. Didelę tyrimo dalį užima temperatūros, slėgio, drėgnumo įtaka garso greičiui ore, kadangi tai labiausiai įtakoja rezultato tikslumui. Darbą sudaro 6 dalys: įvadas, vėjo greičio matuoklių apžvalga, matuoklio sudarymas, ultragarso greitis dujose, matuoklio eksperimentinis tyrimas, apibendrinimas ir išvados, literatūra. Darbo apimtis – 48 p. teksto be priedų 46, 30 iliustr., 13 lent., 19 bibliografinių šaltinių.lit
dc.description.abstractAccording ICAO in the airport the should have been wind speed measurer, the measurer has to get result fast and sharp measuring the weather mass flow speed, this information was to be transferred to the airport operating center. AERODROME METEOROLOGICAL OBSERVING SYSTEMS STUDY GROUP (AMOSSG) Agenda Item 5. Chapter 4 to Annex 3 2.4.3 Several items regarding the operational requirements for wind measurement were discussed, such as: a) the accuracy of wind measurements at aerodromes as the infrastructure at the aerodromes of today might have a significant impact on the wind climate; b) the siting and height of the measurements; c) the average procedures for the wind measurements in relation to the aircraft performance; d) the definition and dissemination of cross-, head- and tailwind and gusts; e) the dissemination of calculated wind in addition to or instead of measured wind; f) the dissemination of the wind data to the users; etc., etc. In this work i have viewed the best weather flow measurer, i have investigated them, i have determind that the most suitable is the ultrasonic wind speed measurer, i made a module, determined when and from which phenomenon sound speed in the air is determined, as this affects the measurer error cases, i made a sample to test and determine the errors that could occur. The system is capable to change its configuration when the measuring conditions are varied. The experimental results of verification of the proposed basic algorithm are presented. Thesis consist of: 48 p. text, 30 pictures, 13 tables, 19 bibliographical entries.eng
