Zasnova in izdelava modela letala za preizkuse v vetrovniku

Draginc, Leonard (avtor), Petrović, Igor (mentor)

V diplomskem delu smo zasnovali in izdelali daljinsko voden model letala za preizkuse v vetrovniku. V programu SolidWorks Student Standard smo, na podlagi omejitev vetrovnika na Fakulteti za strojništvo, izdelali model letala in sistem, ki mu omogoča premikanje masnega središča. Model smo izdelali s 3D tiskalnikom in ga opremili, da je daljinsko voden. Preizkusili smo ga v vetrovniku in dokazali, da je model letala zmožen premika po navpični osi, rotacije okoli navpični osi, rotacije okoli vzdolžne osi in rotacije okoli prečne osi. Izmerili smo minimalno hitrost in jo primerjali z izračunano. Razlika med izmerjeno in izračunano ni bila velika, kar nakazuje, da smo naredili model, ki je primeren tudi za natančne preračune ostalih parametrov leta. Modelu letala lahko med letom spreminjamo položaj masnega središča, naprej ali nazaj od ravnovesne lege in s tem vplivamo na spremembo letalnih lastnosti modela.

Izvleček

In our thesis, we designed and manufactured a remote-controlled model aeroplane for wind tunnel testing. Using SolidWorks Student Standard, we created a model aeroplane that adheres to the limitations of the wind tunnel at the Faculty of Mechanical Engineering and a system that enables us to move its centre of gravity. We then 3D-printed it and equipped it for remote control. We tested it in the wind tunnel which confirmed the model's ability to move along its vertical axis and rotate around its vertical, longitudinal and lateral axis. We measured its stall speed and compared it with the calculated stall speed. The difference was small indicating that we created a model suitable for accurate testing of other flight parameters. We can change the model's centre of gravity mid-air, fore or aft of its equilibrium position and therefore alter its flying characteristics.
