Report presenting an investigation to determine if certain combinations of design nozzle-exit velocity distribution and wall contouring can alter the three-dimensional flow characteristics such that nozzle mass flow cannot be predicted by ordinary two-dimensional design techniques. Four nozzle configurations with different wall contours and velocity distributions were tested. Results regarding the comparison of analytical and experimental values of mass flow are provided.

In the initial uranium solution testing of the Purex prototype facility uranium evaporator, failure of the concentrator feed pump, along with other contributing circumstances discussed later, resulted in an overconcentration of the uranyl nitrate solution to the point of incipient denitration. The overconcentration was accompanied by the evolution of brown nitrogen dioxide fumes from the concentrator. Examination of the evaporator contents after the incident has led to the conclusion that a rapid rection of nitric acid with organic material may also have occurred. The pressure buildup surmised to have accompanied the nitric acid-organic reaction apparently jarred the ceramic Raschig-ring packing in the stripping tower surmounting the concentrator tubes sufficiently to chip many of them badly. Ceramic dust and chips from the Raschig rings were found mixed with the uranium-bearing concentrator residue in almost the entire concentrator pot and filling more than half of the tubes.

Report presenting an investigation to determine the pressure-recovery and mass-flow characteristics of an inlet configuration designed to be less sensitive to positive angle-of-attack operation than a conventional conical inlet. Results regarding the straight plate, plate swept 47.5, plates swept 42 degrees and 24 degrees, perforated plates, and a general comparison are provided.

The root locus method of the treatment of stability problems in the field of servomechanisms is briefly summarized. A simple mechanical instrument of the analogue type (a summing device) containing no gear mechanisms, and designed to do most of the numerical work of the root locus method, is also described.

Results regarding an investigation to determine the horizontal- and vertical-tail contributions to the static lateral stability of a complete-model swept-wing configuration at high subsonic speeds. Generally, Mach number effects within the range studied and wing effects on the tail contribution were small and the overall trends of the data of the present investigation agreed with those which have been established at low speeds.
