Abstract:V diplomskem delu je predstavljen razvoj in preizkus merilnega sistema, ki temelji na pet-luknjasti Pitotovi cevi in diferencialnem merjenju tlaka za določitev hitrosti zraka, vpadnega kota (AOA) in bočnega kota (SSA). Pitotova cev je bila izdelana s SLA 3D-tiskanjem, nato pa mehansko pregledana. Zaradi nezadostnega zaznavanja tlaka pri fizični kalibraciji je bila uporabljena nadomestna izvedba iz silikonskih cevk. Virtualna kalibracija je pokazala stabilne in primerljive koeficiente z literaturo, fizična in eksperimentalna testiranja pa so potrdila funkcionalnost sistema z največjim odstopanjem 3,5 m/s. Rezultati nakazujejo možnosti nadaljnje optimizacije in integracije sistema v realne aplikacije.

Title:Development of a modular measurement system with a 5-hole Pitot tube
Abstract:This thesis presents the development and testing of a measurement system based on a 5-hole Pitot tube and differential pressure sensing for determining airspeed, angle of attack (AOA), and side slip angle (SSA). The Pitot tube was manufactured using SLA 3D printing and mechanically inspected. Due to insufficient pressure detection during physical calibration, a substitute design with silicone tubes was applied. Virtual calibration demonstrated stable and literature-comparable coefficients, while physical and experimental tests confirmed system functionality with a maximum deviation of 3.5 m/s. Results highlight the potential for further optimization and integration of the system into real-world applications.
Keywords:Pitot tube, differential pressure, AOA, SSA, aerodynamics
