Study of stress-strain state (SSS) and type of stress state of a closed model of the wing using speckle interferometry

Nyan M.H., Volkov I.V.

Object. In this article, the stress-strain state (SSS) of the model closed wing of the aircraft is investigated by experimental and computational analysis using speckle-holographic interferometry.

Purpose. As a result of the study of the wing model, to reveal and demonstrate the possibilities of experimental and computational analysis using speckle holography.

Methodology. Experimental study of the stress-strain state of structures was carried out using an experimental load device.

Results. An algorithm for experimental and computational analysis of the stress-strain state of structures using speckle holography is developed and the results of studies are demonstrated on the example of an experimental load device.

Scope of the results. The research results can be used to develop the concept of the power circuit of the aircraft (LA) with a closed system of wings, which is structurally one of the most promising, as it has many potential advantages related to the reduction of its weight, increase stiffness and decrease deformations, with the possibility of direct control of lift and side forces.

Summary. One of the most important aspects of speckle holographic interferometry is the quality of the resulting speckle hologram, on which its diffraction efficiency largely depends. At the same time, the improvement of diffraction efficiency in solving practical problems is carried out due to the selection of the developer of photographic plates, the installation of a certain exposure time and the choice of methods of processing photographic plates. However, in practice, there are often problems of obtaining the maximum diffraction efficiency of holograms. We made the choice of developer, exposure time, as well as methods of photo processing of speckle holograms in counter beams in the course of practical experiment.

Practical significance. The described technology unextendable registration of speckle holograms can be used in the research process VAT field aviakonstruktor in the zones of stress concentration, as well as their identification during the industrial field tests.
