Download or read book Charts of Pressure Rise Obtainable with Airfoil-type Axial-flow Cooling Fans written by A. Kahane and published by . This book was released on 1947 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charts are presented to show the pressure rise that is obtainable in an engine-cooling installation with a typical airfoil-type propeller-speed fan. The charts cover fans of the stator-rotor, rotor-stator, and rotor alone configurations, with blades incorporating both the highly cambered 65-series blower-blade sections and the conventional low-cambered airfoil sections. The effects of operation of a geared fan with rotational speeds limited by compressibility considerations and the effects of initial rotational inflow are indicated. Use of the charts to predict the pressure rise obtainable with any fan of the types considered is illustrated in a sample calculation.
