Available in PDF, EPUB and Kindle. Book excerpt: A number of studies relating to the use of Freon-12 as a substitute medium for air in aerodynamic testing have been made. The use of Freon-12 instead of air makes possible large savings in wind-tunnel drive power. Because of the fact that the ratio of specific heats is approximately 1.13 for Freon-12 as compared with 1.4 for air, some differences exist between data obtained in Freon-12 and air. Methods for predicting aerodynamic characteristics of bodies in air from data obtained in Freon-12, however, have been developed from the concept of similarity of the streamline pattern. These methods, derived from consideration of two-dimensional flows, provide substantial agreement in all cases for which comparative data are available. These data consist of measurements throughout a range of Mach number from approximately 0.4 to 1.2 of pressure distributions and hinge moments on swept and unswept wings having aspect ratios ranging from 4.0 to 9.0, including cases where a substantial part of the wing was stalled.

Anderson and published by . This book was released on 1953 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of four experimental and two conventional 75-millimeter-bore (size 215) cylindrical-roller bearings was conducted over a range of DN values (product of bearing bore in mm and shaft speed in rpm) from 300,000 to 2,300,000, radial loads from 7 to 1613 pounds, and oil flows from 2 to 8 pounds per minute with a single-jet circulatory oil feed. The four experimental bearings were equipped with outer-race-riding cages and inner-race-guided rollers. One conventional bearing was equipped with an outer-race-riding cage and outer-race-guided rollers, while the second conventional bearings was equipped with an inner-race-riding cage and inner-race-guided rollers. Each of the six test bearings was equipped with a different design cage made of nodular iron.
