Experimental Investigation of Air-Cooled Turbine Blades in Turbojet Engine: 1: Rotor Blades With 10 Tubes in Cooling-Air Passages

Description: Report presenting an investigation to experimentally determine the effectiveness of air cooling several turbine-blade configurations in a turbojet engine. The results obtained with the first configuration, which was a hollow blade shell with 10 tube inserts, are presented. A description of factors leading to the design are provided as well as the correlated cooled-blade temperatures, solid-blade temperatures, cooling-air-temperature increase through radial passages, and blade failure are provid… more

Preliminary Internal Performance Data for a Variable-Ejector Assembly on the XJ79-GE-1 Turbojet Engine, 2, Afterburning Configurations

Description: Internal performance of an XJ79-GE-1 variable ejector was experimentally determined with the primary nozzle in two representative after-burning positions. Jet-thrust and air-handling data were obtained in quiescent air for 4 selected ejector configurations over a wide range of secondary to primary airflow ratios and primary-nozzle pressure ratios. The experimental ejector data are presented in both graphical and tabulated form.

An Investigation of the Stream-Tube Power Losses and an Improvement of the Diffuser-Entrance Nose in the Langley 8-Foot Transonic Tunnel

Description: Report presenting surveys of the distribution of total pressure, total temperature, and static pressure at a number of stations in the slotted test section and diffuser of the transonic tunnel with early and improved diffuser-entrance noses installed at the ends of the slots. Results regarding power losses with the original diffuser-entrance nose, development of revised diffuser-entrance noses, and energy losses in the tunnel with the final diffuser-entrance nose are provided.

Flight Determination of the Pressure Recovery and Drag Characteristics of a Twin Side-Inlet Model at Transonic Speeds

Description: Report presenting free-flight and free-jet testing of a twin side-inlet configuration, including a pilot's canopy and a wheel-well fairing, between a range of Mach numbers from 0.8 to 1.55. Using side inlets provides two important advantages: the inlet can be located closer to the engine and it frees up the nose for other uses. Results regarding the effects of oscillating flow, external-drag coefficient, and total-pressure recovery are provided.

Experimental Investigation of the Effect of Entrance Width-to-Height Ratio on the Performance of an Auxiliary Scoop-Type Inlet at Mach Numbers From 0 to 1.3

Description: Memorandum presenting an investigation of variable-area auxiliary inlets intended to provide for the variation of engine air requirements with speed and altitude. Three auxiliary scoop inlets were tested in combination with a nose inlet at a range of Mach numbers tested at zero angle of attack.

Slotted-boundary interference effects on wedge airfoils at low supersonic Mach numbers

Description: Report presenting an experimental investigation of pressure disturbances caused by the reflection of two-dimensional shock waves from a slotted boundary at Mach numbers between 1.0 and 1.5. Simple-wedge airfoils with three different apex angles were used to generate shock waves and the static pressures ere measured at various points along the surface of each airfoil.

Test of an aerodynamically heated multiweb wing structure (MW-1) in a free jet at Mach number 2

Description: Report presenting testing of a multiweb wing structure, representing an airplane or missile wing, under simulated supersonic flight conditions to determine the transient temperature distribution. The aerodynamic loads caused the model to fail near the end of the test. The failure is analyzed and it is determined that the model failed as a result of the combined action of aerodynamic heating and loading.

THE ISOTRON

Description: Most methods of separating isotopes depend on the use of a large magnetic field. The isotron is an electromagnetic device for separating isotopes, but it effects the separation by the use of radiofrequency voltages instead of magnetic fields. It has the advantage that plane sources of large area can be used instead of the slit sources to which most magnetic methods are limited. Before entering into any discussion of the details, a simplified description of the principles of the method is given.

Development of an Ion Exchange Process for the Recovery of Vanadium

Description: A process for recovering vanadium from acid leach liquors by ion exchange using either columns or resin-in-pulp has been developed. The process is economically feasible, and operating techniques were developed which made the process practical from an operating standpoint. The theory, chemistry, and characteristics of the vanadium ion exchange process are fully discussed.

REPORT OF FIRE IN LABORATORY HOOD, WING I, BUILDING 4500, MAY 22, 1959

Description: Approximately 16 to 18 liters of isopropyl alcohol in a 20-liter glass carboy in a floor type hood were ignited by infrared heat lamps used to heat the carboy and contents. A technician received several minor lacerations on the hand. (C.H.)

Quarterly Progress Report for the Period April 1, 1958 to June 30, 1958

Description: The principle progess during the second quarter of 1958 consisted of: accelerating the planning, scheduling, and coordination of the process-water and in-pile test loop irradiation programs; performing two-enrichment non-cycled core studies to determine the improvement in the radial hot channel factor over that which would apply for a uniform core; recalculating the contribution of control to the temperature coefficient using better thermal constant values and an improved method of obtaining co… more

Thermodynamics of Irreversible Processes: The Experimental Verification of the Onsager Reciprocal Relations

Description: In the last twenty years a thermodynamic theory of irreversible processes (TIP) has been vigorously developed which has been able to treat irreversible phenomena in a detailed way. The present macroscopic form of the theory was suggested primarily by the statistical mechanical investigations of Onsager. The presently available experimental data are collected for a variety of quite different irreversible phenomena and it is shown that this evidence does indeed verify the Onsager Reciprocal Relat… more

A Review of Potential Radionuclides Produced in Weapons Detonations

Description: ABS>Estimates have been made of what the probable radionuclides produced in weapons detoriations, including fission products and neutron-induced radionuclides in air, soils, and sea water will be. The nuclear and decay properties and some metabolic or biological properties of these nuclides are tabulated where available. Estimates are made of the amounts of the radionuclides produced in weapons detonations. Some radionuclides are discussed with respect to their particular biological interest fr… more
