Abstract
A swirler includes a tubular body having a row of secondary radial swirl vanes. A tubular ferrule adjoins the body at the secondary vanes, and includes a row of primary swirl vanes. The primary vanes are disposed axially obliquely to the secondary vanes, with a common annular inlet facing radially outwardly for swirling air radially inwardly therefrom with axial momentum into the tubular body.
