Book excerpt: Summary: Flight tests were made at high speeds with a P-47D airplane to determine the flow characteristics, as indicated by wool tufts, on a section of the upper surface of the wing. The behavior of the tufts, which were distributed over a section of the wing from 39.5 to 52.5 percent semispan, was determined from motion pictures. The tests were made in straight flight and in turns under conditions in which airplane lift coefficients from 0.10 to 0.54 and airplane Mach numbers from 0.58 to 0.78 were obtained. The results of the tests indicated that the flow remained smooth over the test panel until the critical Mach number of the panel was exceeded by 0.08 at a lift coefficient of 0.10 and by 0.05 at a lift coefficient of 0.50. Beyond these Mach numbers, the tufts indicated unsteadiness of flow and, finally, local separation when the Mach number exceeded the critical value by 0.13 at a lift coefficient of 0.10 and by 0.10 at a lift coefficient of 0.50. The region of separated flow originated in the neighborhood of 30 percent chord at high lift coefficients and 45 percent chord at low lift coefficients. Separation appeared to extend over not more than 15 percent chord.

Book Synopsis Flight Investigation at High Speeds of Profile Drag of Wing of a P-47D Airplane Having Production Surfaces Covered with Camouflage Paint by : John A. Zalovcik

Zalovcik and published by . This book was released on 1946 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: A flight investigation was made at high speeds to determine the profile drag of a P-47D airplane wing having production surfaces covered with camouflage paint. The profile drag of a wing section somewhat out-board of the flap was determined by means of wake surveys in tests made over a range of airplane lift coefficients from 0.06 to 0.69 and airplane Mach numbers from 0.25 to 0.78. The results of the tests indicated that a minimum profile-drag coefficient of 0.0097 was attained for lift coefficients from 0.16 to 0.25 at Mach numbers less than 0.67. Below the Mach number at which compressibility shock occurred, variations in Mach number of as much as 0.2 appeared to have no effect on profile-drag coefficient. The variation in Reynolds number corresponding to this variation in Mach number, however, was appreciable and may have had some effect on the results obtained. Comparison of the Mach number at which shock losses were first evident in the wake with the critical Mach number indicated that shock was not evident until the critical Mach number was exceeded by at least 0.025.

This book was released on 1947 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rupture-test characteristics at 1350 degrees F of two wrought alloys in the solution-treated and aged condition, NR-82 (6059 modified-low carbon) and NR-84 (N-155 modified-low carbon), and three precision-cast alloys in aged condition, NR-71 (X-40), NR-87 (Co-Cr-Ni base-9Mo) and NR-90 (Co-Cr-Ni base-5Mo, 5W) are reported. The properties are shown to compare favorably with those of the strongeest similar alloys previously investigated. A correlation of NACA and OSRD data is presented, showing the variation of ruture strengths with temperature for the alloys between 1350 degrees and 2000 degrees F.
