Elliptic Cones Alone and with Wings at Supersonic Speed
"To help fill the gap in the knowledge of aerodynamics of shapes intermediate between bodies of revolution and flat triangular wings, force and moment characteristics for elliptic cones have been experimentally determined for Mach numbers of 1.97 and 2.94. Elliptic cones having cross-sectional axis ratios from 1 through 6 and with lengths and base areas equal to circular cones of fineness ratios 3.67 and 5 have been studied for angles of bank of 0 degree and 90 degrees. Elliptic and circular cones in combination with triangular wings of aspect ratios 1 and 1.5 also have been considered" (p. 975).

OXIDATION OF PLUTONIUM (III) BY SODIUM NITRITE
The reaction velocity constant for the oxidation of Pu(III) by nitrite in HNO/sub 3/ solution containing ferrous sulfanate is given. The reaction rate was found to be measurable by means of spectrophotometry. The data indicate the reaction to be a pseudo first-order reaction in the region of HNO/sub 3/ and nitrite concentration of interest. The reaction velocity constant, expressed as a first-order reaction with respect to Pu, was found for several values of HNO/ sub 3/ and nitrite concentrations. The HNC/sub 3/ reaction velocity constant relationship is given. The oxidation of the ferrous sulfamate--Pu(III Pu(III) solution proceeds successively through the sulfamate, ferrous, and Pu(III) ions. An autocatalytic mechanism is asscciated with the oxidation of both ferrous and Pu ions which obviates the possibility of simple calculations of constants based on nitrite concentration. An empirical relationship between the reaction velociiy constant and the (added) nitrite concentration is given. (auth)

Notes on a Large-Scale Statistical Program for the Establishment of Maneuver-Loads Design Criteria for Military Airplanes
Report presenting an outline of a proposed statistical program to collect data for the establishment of more realistic maneuver-loads design criteria. Some sample experimental data are also included to indicate possible methods of statistical analysis and the potential sample size needed for the program.

Some Effects of Wing Height on the Vertical-Tail Pressure Distributions of a Complete Model in Sideslip at High Subsonic Speeds
Report presenting an investigation in the high speed tunnel of some effects of wing height and angle of attack on the vertical-tail pressure distribution of a complete model in sideslip at high subsonic speeds. The 45 degree swept wing had an aspect ratio of 4, a taper ratio of 0.30, and NACA 65A006 airfoil sections parallel to the model plane of symmetry. Results regarding vertical-tail loads and vertical-tail center of pressure are provided.
