High-Altitude Performance of an Experimental Turbojet Combustor Having Variable Primary-Air Admission

Description: Report presenting an investigation of 47 experimental tubular designs embodying variable primary-air openings to control the fuel-air ratio in the combustion zone at simulated high-altitude operating conditions for a representative 5.2-pressure-ratio engine. The performance characteristics considered were combustion efficiency, operating range, and pressure loss. Results regarding the effect of fuel injector design, effect of primary-air baffles, and performance characteristics of the best mode… more

High-Energy Electron Scattering and the Charge Distribution of Selected Nuclei

Description: Experimental results are presented of electron scattering by Ca, V, Co, In, Sb, Hf, Ta, W, Au, Bi, Th, and U, at 183 Mev and (for some of the elements) at 153 Mev. For those nuclei for which asphericity and inelastic scattering are absent or unimportant, i.e., Ca, V, Co, In, Sb, Au, and Bi, a partial wave analysis of the Dirac equation has been performed in which the nuclei are represented by static, spherically symmetric charge distributions. Smoothed uniform charge distributions have been ass… more

High Energy Physics

Description: Without a little further explanation the title of this article may not convey a definite meaning to all readers, so I would like to start by pointing out that ''high energy'' refers to the energy of individual bombarding particles used to produce nuclear disintegrations, and not to situations where a large aggregate amount of energy is involved, as in an atomic power plant. The next question might be, when is energy considered ''high?'' To discuss this, we need a scale for measuring particle en… more

High Radiation Levels at the Discharge Faces of the Reactors

Description: Undesirably high radiation dosage rates are being encountered in the discharge areas during reactor outages. This is costly to operations in terms of burn-out time, extra work crews, and extended outages require to complete scheduled work. Significant savings in operating costs would be realized if the rear face radiation levels could be reduced during shutdowns. As a first step towards this some measurements have been made to identify and locate the major sources of this radiation. These resul… more

A High Range Beta-Gamma Survey Instrument

Description: A new model High Range Beta-Gamma Survey Instrument, refer to blueprint numbers H-4-2760 and H-4-2761, was designed which utilizes a circuit similar to that of the older model but incorporates three ranges of 0-5 R/hr, 0-50 R/hr, and 0-500 R/hr.

High-Speed Cascade Tests of a Blade Section Designed for Typical Hub Conditions of High-Flow Transonic Rotors

Description: Report discussing high-speed cascade tests made of a blade section designed for conditions typical of the hub section of high-flow transonic rotors. The intent of the testing is to provide information on the effects of local surface Mach numbers on blade performance. The test results, effect of more forward location on peak surface velocities, effect of increase in pressure-rise coefficient, effect of Mach number and pressure rise on turning angle, and a comparison of variation in momentum-loss… more

High-Speed Cascade Tests of the NACA 65-(12A(sub 10))10 and NACA 65-(12A(sub 2)I(sub 8b))10 Compressor Blade Sections

Description: "Two-dimensional porous-well cascade tests of the NACA 65- (l2Al0) 10 and NACA 65-(l2A2I8b)10 blade sections were made at Mach numbers from 0.3 to choking in most cases. Data were obtained at solidities of 1.0 and 1.5 at inlet-air angles of 45 deg. and 60 deg. for both blade sections. With a solid--wall modification to the cascade tunnel, schlieren observations were made of the flow in cascade at a solidity of 1.5 and inlet-air angle of 45 deg. and at a solidity of 1.0 and inlet-air angle of 60… more

High Temperature Scaling Behavior of Zirconium : Second Technical Progress Report

Description: This technical report summarized studies in the high temperature scaling of zirconium, and covers the period from March 1, 1955 to December 15, 1955. One technical progress report covered the progress of the investigation from April 1, 1953 to march 1, 1955. The previous work was concerned largely with the scaling behavior of zirconium in air, pure oxygen, pure nitrogen and mixtures of oxygen and nitrogen. The major finding arising from these studies was that the peculiar scaling behavior of zi… more
