Introduction: "The observations reported in this document were obtained by C.H. Pitt during his assignment to the Corrosion Group September through October 1951. The tubes examined were: 1.) 0893-F Discharged for corrosion examination after leaking; 2.) 1488-DR Discharged to determine caused of obstruction; 3.) 2276-D Discharged for corrosion examination; 4.) 2376-D Discharged for corrosion examination; 5.) 1185-H Discharged to evaluate the effect of magnesium front dummies."

"A brief study was made of the effects of slots in a test-section wall on the reflection from the wall of an incident oblique shock wave at a free-stream Mach number of 1.62. The reflection was observed with an interferometer for various combinations of slot width, spacing, and contour. The reflections from the open and the closed portions of the wall, being at different angles to the wall, were not superimposed and, therefore, did not cancel each other" (p. 1).

Report presenting pressure distributions measured along prolate spheroids of fineness ratios 3 to 20 and along a slender body of fineness ratio 12 are compared at subsonic and transonic speeds and several angles of attack. The experimental results, prediction of incompressible pressure distribution along the 0 degree and 180 degree meridians, prediction of subsonic pressure distribution along the meridians, prediction of subsonic pressure distributions around prolate spheroids, effect of fineness ratio and angle of attack on separation, and prediction of transonic pressure distribution.
