Abstract

U radu se opisuju uređaji za mjerenje tlaka u aerodinamičkim tunelima, te svrha i podjela
aerodinamičkih tunela. Detaljno je opisan sustav za akviziciju tlaka Intelligent Pressure Scanner
9016 kojega proizvodi tvrtka Pressure Systems. Sustav za akviziciju tlaka u aerodinamičkom
tunelu AT‐1 Fakulteta prometnih znanosti koristi se za mjerenje rasporeda tlaka na NACA 2421
aeroprofilu, a sastoji se od senzora, mjerne opreme i računala sa odgovarajućim programom.
Tlak iz senzora pretvara se u digitalni oblik kako bi se pomoću računalnog programa prikazao
na zaslonu računala. U sklopu završnog rada, navedeni sustav za akviziciju tlaka spojen je na
aeroprofil u ispitnoj sekciji tunela. U radu je opisan način mjerenja tlaka i prenošenja podataka
s mjernog mjesta do računala kao i potrebne postavke sustava kako bi ispravno radio. Također
je ispitana ispravnost i točnost instaliranog sustava usporedbom sa postojećim sustavom
mjerenja rasporeda tlaka pomoću piezometarske harfe.

Abstract (english)

The main topic of the work are devices for measuring the pressure in wind tunnels and the
purpose and division of the same. The system for acquisition of pressure Intelligent Pressure
Scanner 9016, which is produced by the company Pressure Systems is detailly described. The
system for acquisition of pressure in wind tunnel AT‐1 in the Faculty of traffic sciences is used
for measuring of pressure distribution over NACA 2421 airfoil, and it is contained of sensors,
measuring equipment and computers with corresponding programs. The pressure from
sensor is transformed into digital shape so it could be shown on the screen, with the help of
computer program. For the purpose of the final work, mentioned system for the acquisition
of pressure is connected to the airfoil in the test section of the tunnel. The way of measuring
pressure and transferring data from the measure point to the computer and the essential
settings needed for the system to work properly are also described. Another part of the work
is the comparison of correctness and accuracy of the installed system with the existing system
by measuring of pressure distribution with piezometric harp.
