FIELD: machine building.
SUBSTANCE: exhaust collector for a gas turbine unit. Exhaust collector includes a front panel, a rear panel and a side panel. Side panel includes a circumferential portion, a first contoured portion, and a second contoured portion. Circumferential portion extends about the exhaust collector axis with a constant radius. First contoured portion and the second contoured portion are each between the circumferential portion and the exhaust outlet and include a plurality of curved sections with alternating concavity. Each of the plurality of curved sections extends from the front panel to the rear panel.
EFFECT: increased rigidity reduces or prevents high-cycle fatigue, while improving the reliability of the exhaust collector and reducing downtime of the gas turbine engine.
