Abstract

FIELD: experimental aerodynamics. SUBSTANCE: model surface mounts sensing element in the form of film made of flexible material-polymer gel of desired thickness with known shear modulus; markers are applied to film and model surfaces, and shear strain of film caused by flow is measured by, say, interference method; shearing stress is determined using Hooke's law for shear strain. Markers may be made in the form of reflection grating placed on model surface (under film) and transmitting grating on film surface enabling use of moire phenomenon for recording shear strain. EFFECT: improved accuracy and informative capacity due to determining local values of shearing stress. 5 cl, 1 dwg
