Abstract

Tema rada je Projektiranje mjernog sustava za umjeravanje visinomjera. Visinomjer je barometarski što znači da radi na principu promjene statičkog tlaka. Navedeni su različiti načini mjerenja visine kod zrakoplova, te navedeni nedostaci kod barometarskog visinomjera. Također je dan detaljan opis barometarskog visinomjera. Navedeni su instrumenti i etaloni koji su korišteni pri izradi ovog rada. Naveden je detaljan opis etalonske tlačne vage koja je korištena za umjeravanje. Postupak umjeravanja i mjerna linija su također detaljno objašnjeni (postupak spajanja mjerne linije, provedba mjerenja). Prikazana je veza između promjene visine i statičkog tlaka. Na kraju rada prikazani su podaci umjeravanja, te mjerna nesigurnost.

Abstract (english)

The subject of this thesis is Design of measuring system for calibration of altimeters. Altimeter is barometric which means it works on principe of change of static pressure.There are listed different ways of measuring height in the aircraft and also listed shortcomings of barometric altimeter. In this thesis also is provided a detailed description of barometric altimeter. There are listed the instruments and standards that are used in the preparation of this work. There is a detailed description of the reference pressure piston gauge that is used for calibration. The process of calibration and measurment line are also explained in detail ( installation of measurment line, the implementation of measurment). The relation between height changes and static pressure are also shown. At the end of the thesis are represented data of calibration, and measurement uncertainty.
