The paper presents a draft model of a test stand for the measurement of the efficiency of automatic positioning systems of radar antenna reflectors. The described test stand was designed and constructed for the identification of the aircraft position during air show aero-batics. The authors of the paper have presented and discussed in detail the test stand’s individual components and measurement equipment.
The longitudinal rail vehicle dynamics dealing with the movement disturbance along the railway track are part of the overall vehicle dymamics. Most of the longitudinal dynamics considerations relate to more than one vehicle up to the whole train. The aim of the article are chosen problems of the longitudinal rail vehicles dynamic issues and then more exactly of the train braking. Inextricably linked...
The article presents the particulate matter measurement analysis of a passenger vehicle equipped with diesel particulate filter in real operating conditions. The tests were conducted in the Poznań urban agglomeration on routes with variable speed limits. The procedure included two different driving styles – aggressive and normal. The measurement of particulate matter included their mass, surface area,...
The article discusses the current technologies and methods of fast, safe, and efficient charging of modern high-capacity batteries. The aim of the research is to determine which of the currently used technological solutions are most suitable for use in charging of supercapacitor energy storage devices. Modern solutions applicable to battery technologies which due to the operating characteristics and...
The article discusses the subject of light duty vehicles exhaust emissions in real driving conditions and their connection with fuel consumption. Tests were carried out in the Poznan agglomeration area on roads with various speed limits. The driver was to drive the same distance first driving in an aggressive manner than normally. Emissions of the following compounds were measured using a SEMTECH...
The temperature inside the heat exchanger pipe in a steam boiler was subjected to analysis. Heating of the pipe with and without the scale was considered. A calculation model was presented describing the inverse problem of a geometrical type. It allows determining the thickness of the boiler scale based on the measurements of the temperature inside the pipe and the heat flow density on t he outer...
