Способ и устройство для активного контроля сложного профиля глубины пропитки кремнийорганическими соединениями изделий из пористой керамики

Abstract

The article proposes a photometric method for active control of the depth of impregnation of porous shells of objects of control (aircraft), moving at ultra-high (up to 10 "swings") speeds and capable of a sharp change in flight trajectory. The proposed method for active control of the depth of impregnation of porous shells by measuring and analyzing the luminescence intensity of the colored impregnation boundary, as well as a device for controlling the depth of impregnation, provide a high degree of resistance of the shell of an object to mechanical stress. The novelty of the proposed technical solution lies in the following: triphenylmethane organic dye is additionally introduced into the oligomer dissolved with acetone, which ensures the contact of the impregnating substance with the inner surface of the object shell. In addition, in the process of impregnation, the shell of the object is irradiated with a laser beam from the outer surface and the change in the luminescence intensity of the colored oligomer, depending on the depth of impregnation, is recorded.
