Abstract
913,930. Axial-flow fans. SOC. LYONNAISE DE VENTILATION INDUSTRIELLE. Dec. 3, 1959 [Dec. 12, 1958], No. 41154/59. Class 110 (1). In an axial-flow fan comprising a wheel housed in an outer substantially cylindrical housing, the wheel comprises a hub increasing in section from the inflow side to the outdow side and at least two blades, and a section of each blade, taken on a cylinder coaxial with the axis of rotation of the wheel, has a leading edge 5 and a trailing edge 6 which taper and a line I of maximum thickness measured on a circle of the cylinder, which line, if extended to the chord L of the section intersects the chord at a point thereof located between and ¢ of the length of the chord measured from the leading edge 5.
