Premazi osetljivi na pritisak - nova mogućnost vizualizacije strujanja / Pressure sensitive paints: New possibility of flow visualization

Abstract

U radu je opisan novi metod vizualizacije strujanja i merenje raspodele pritisaka po površini, baziran na premazima, odnosno bojama osetljivim na pritisak - PSP. Ovi premazi nalaze široku primenu u različitim oblastima nauke i industrije. Prikazani su rezultati ispitivanja ovom metodom u svetski poznatim aerodinamičkim laboratorijama. Prelazak sa klasičnih davača pritiska na PSP tehnologiju omogućava brže i preciznije merenje pritisaka, što će omogućiti poboljšanje karakteristika aviona. / The description of the new method for flow visualization and surface pressure distribution measurement, based on emulsions named pressure sensitive paints - PSP, are given in this paper. These paints have large applications in different branches of science and industry. The results of this research method from the most famous -world aeronautical laboratories are presented. The switch from pressure taps to pressure sensitive paints enables fast and accurate pressure testing and finally predictable and improved aircraft performance.
