FIELD: power industry.
SUBSTANCE: invention relates to wind-power engineering and is intended to improve wind turbine parameters. A pressure-controlled device for improvement of wind turbine parameters includes a casing that contains at least the first and the second sections. The first section has conicity that is higher than that of the second section. The above sections are separated from each other with a gap so that pressure reduction is provided inside the casing with acceleration of an air flow through the casing.
EFFECT: invention is aimed at increase of output power taken from a turbine owing to using a modified casing strengthening an airflow directed to turbine blades.
