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.

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.
