Purpose. Development of the software for the main ventilation fan, which allows creating, correcting and replenishing the database, taking into account aerodynamic and energy characteristics, to make a choice and determine the actual operating modes. The methodology consists in the development of the VGP program, which designed to create, replenish and update the database. Finding. This program allows you to significantly facilitate the calculation of the selection of the fan of the main

Calculations showed that the dependence describes with sufficient accuracy the descending parts of the aerodynamic characteristics of existing main ventilation fans. Practical implications. On the basis of this program, the calculated values of head and flow, the power consumption of a particular fan of the main ventilation, as well as the creation, updating and correction of a database of aerodynamic and energy characteristics are carried out.
