Book Description
The momentum integral equations are derived for the boundary layer on an arbitrary curved surface, using a streamline coordinate system. Computations of the turbulent boundary layer on a slightly yawed cone are made for a Prandtl number of 0.729, wall to free-stream temperature ratios of 1/2, 1, and 2, and Mach numbers from 1 to 4. Deflection of the fluid in the boundary layer from outer stream direction, local friction coefficient, displacement surface, lift coefficient, and pitching-moment coefficient are presented.

Book Description
Extensive fatigue tests were made on annealed Armco iron and plain carbon and alloy steels heat-treated to different strengths and microstructures. Statistics of fatigue-fracture curves and endurance limits were determined from the experimental data obtained and, for various other materials, from a survey of literature. The results were analyzed to show the relative effects of various metallurgical factors on the statistical nature of fatigue properties. Other phases of the problem studied include: dependence of statistical variation in fatigue life on stress level in the fracture range, statistics for location of crack initiation, size effect, understressing effect, and the form and method of plotting the S-N diagram.

Book Description
The constant-pressure specific heat of carbon dioxide has been measured over the range of temperatures and pressures from ambient condtions to 1000 pounds per square inch gage and 1000 degrees F using a steady-flow calorimeter operated on an open cycle. It appears that the apparatus as used in this determination will yield values with a probable error of 0.5 percent at the highest temperature level considered. The results of these tests check the widely accepted spectroscopic data within 1 percent. The values at elevated pressure are in reasonable agreement with those derived from the zero-pressure spectroscopic values and the application of the Beattie-Bridgeman equation of state. Only very limited calorimetric data are available in the literature, but substantial agreement exists with those considered reliable.

Book Description
Advances in Aeronautical Sciences, Volume 1 contains the proceedings of the First International Congress in the Aeronautical Sciences, held in Madrid, Spain in September 1958. The book is comprised of survey papers and original contributions that discuss common problems in aeronautics and in space technology. The reader will also find interesting articles that cover topics on the principles of inertial guidance; boundary layer control; VTOL/STOL aircraft; heat resisting material; heat transfer and heat barrier; and jet noises and human factors in aeronautics. Hypersonic speeds; propulsion methods in space and magneto-fluid dynamics are discussed as well. Aeronautics engineers and scientists in allied fields will find the book insightful.
