Abstract
Kako bi se mogla mjeriti aerodinamička opterećenja u zračnom tunelu, potreban je prikladan mjerni uređaj (aerodinamička vaga). Senzori sila dolaze u puno različitih oblika i veličina te je stoga, u uvodnome dijelu, dan kratki pregled vrsta i načela rada senzora takvih uređaja. Dva najčešće korištena senzora za određivanje opterećenja, koja djeluju na model letjelice, su tenzometarske trake i piezoelektrični senzori. Zbog prikladnijih karakteristika mjernih traka uvjetima u kojima će se provoditi ispitivanja (zračni tunel malih dimenzija i brzina), odabrana je mjerna ćelija s tenzometarskim trakama ATI-IA Mini27. Mjerna ćelija ima mogućnost mjerenja tri komponente sile (aksijalnu, normalnu, i bočnu silu) te tri komponente momenta (moment propinjanja, skretanja i valjanja). U drugome dijelu rada predloženo je idejno konstrukcijsko rješenje uređaja za mjerenje aerodinamičkih opterećenja. Uređaj je opremljen spomenutim senzorom sile koji je pričvršćen na mehanizme za kontrolu skretanja i propinjanja modela letjelice. CAD modeli i tehnički crteži sklopa i pojedinačnih dijelova uređaja su također priloženi.
Abstract (english)
To be able to measure aerodynamic loads inside a wind tunnel, a suitable measuring device (force balance) is required. Force sensors come in many forms and sizes, therefore a brief overview of types and principles of operation of sensors used in such devices is given in the introductory part. The two most commonly used sensors for determining loads acting on an aircraft model are strain gauges and piezoelectric sensors. Due to more suitable characteristics of strain gauges to the conditions in which the testing is to be done (small low-speed wind tunnel), an ATI-IA Mini27 strain gauge load cell was chosen. The load cell is capable of measuring three forces (axial, normal and side force) and three moments (pitching, yawing and rolling moment). In the second part of this paper, a conceptual design of an aerodynamic load measuring device is proposed. The device is equipped with aforementioned force sensor which is mounted on the mechanisms for yaw and pitch control of the aircraft model. CAD models and technical drawings of assembly and individual parts of the device are also provided.
