FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of mechanical engineering for gas turbine engines. A rotary device is proposed, containing inner 5 and outer 4 radius walls mating the inlet 8 and outlet 9 sections of a rectangular shape with the possibility of turning the flow by 90º and at least one divider 7 of a radius shape in the cavity. The input edges 12 of the dividers 7 at the inlet to the rotary device are located parallel to the exhaust gas flow, and the number of dividers is made in the range from one to four. The cavity 6 between the inner 5 and outer 4 walls is filled with thermal insulation 10, and the outer 4 wall is made with stiffeners 11. Dividers can be made of sheet low-carbon structural or stainless steel and have a thickness of 2 to 12 mm.
EFFECT: invention is aimed at ensuring minimal aerodynamic losses in the device.
