Abstract
Mjerenja zrakoplovne buke imaju sve značajniju ulogu u zrakoplovnoj industriji. Postoji više metoda mjerenja i analize za različite potrebe i vrste zrakoplovne buke. Najjednostavniji mjerni senzor je piezoelektrični pretvarač koji radi svojih reverzibilnih svojstava može imati ulogu mikrofona. Pri mjerenju aerodinamičke buke na aeroprofilu on je odličan izbor radi svojih malih dimenzija. Za određivanje karakteristika aerodinamičke buke potrebno je kondicijsko pojačalo za pojačanje izmjerenog signala na senzoru, stoga se ono izrađuje. Za potrebe mjerenja također se dizajnira i izrađuje model aeroprofila NACA 2421 s ugrađenim mjernim senzorima. Ugradnjom aeroprofila u aerotunel i spajanjem senzora na računalo preko pojačala, moguće je izmjeriti buku, obraditi podatke i analizirati dobivene rezultate. Korištenjem određenih korekcija moguće je poboljšanje u prikazu rezultata i ispravljanje za neke greške u mjerenjima. U diskusiji su doneseni zaključci o mjerenjima i uočene neke korelacije. Primijenjena metoda se pokazuje vrlo uspješnom i prigodnom za ovakav eksperiment. Također, mogućnosti daljnjeg razvoja i unaprjeđenja metode su mnogobrojne.
Abstract (english)
The role of aircraft noise measurements is becoming more significant for aircraft industry. Various methods of measurement and analysis exist for different uses and types of aircraft noise. The simplest measuring sensor is piezoelectric transducer which can be used as a microphone due to its reversal characteristics. Small dimensions make it a good choice for measurements of aerodynamic noise on an airfoil. Condition amplifier is needed for amplification of signals detected by sensors and for assessment of aerodynamic noise, therefore it is being constructed as well. An airfoil model NACA 2421 with piezoelectric sensors is being designed for the experiment. The airfoil is assembled in wind tunnel which allows noise measurement, data processing and result analysis to be made. By using some measurement correction methods it is possible to improve data representation. Conclusions about measurements and observed correlations are discussed and reviewed. This particular applied method is shown to be very efficient and practical for this kind of experiment. Moreover, there is a lot of potential for improving the method and further development.
