The subject of the research is the attachment of fixed blades of axial mine fans. Within increasing rotational speeds (and increasing centrifugal forces as a result), the loads on the blades and, thus, on their attachments grow. Accordingly, the design of the blade attachment should ensure the required strength of the structure. The key objective of the blade attachment design is to keep stresses and strains within permissible limits (so that the effective stresses are beyond the ultimate values) at the preset rotational speeds. Then methods used to meet the objective include selection of the appropriate characteristics of the materials, variation of structure of the blade attachment and calculation of the attachment strength at each stage to select the most efficient parameters.
