FIELD: machine building. ^ SUBSTANCE: at least on one section of probable occurrence of the defect in the design there provided is the sensor as per the state of which the occurrence and/or development of the defect is determined; at that, as the sensor there used is polymer material to which capsules with colouring agent are introduced and which is applied to the section of probable occurrence of the defect with layer thickness of 0.1-0.15 mm, and availability and/or development of the defect is determined visually as per the sensor colour change. Enoxydiane resin can be used as polymer material. Soluble colouring agents of anthraquinone group can be used as colouring agents. Derivatives of cellulose acetobutyral can be used as material of capsules. ^ EFFECT: receiving timely and accurate information on the design state. ^ 3 cl, 3 dwg |
