Abstract
An exhaust gas nozzle comprising a duct member forming a single exhaust passage and defining an open first end, an open second end, and a centrally-disposed longitudinal axis extending between the first end and the second end. The duct member includes at least a pair of bent wall portions spaced-apart from one another, these bent wall portions extending from the first end to the second end and gradually and increasingly pinching the passage from the first end to the second end. An annular, open-ended windband is connected to the duct member and disposed about the exterior of and in spaced, coaxial relation to the second end. A windband inlet is located below and in the region of the second end and outside the duct member.
