The Early Detection of Fatigue Damage by John Moore( Book )
2 editions published between 1970 and 1971 in English and held by 2 libraries worldwide
The report is the final technical report for a program directed at the development of nondestructive test (NDT) methods for the detection of early fatigue and fracture damage in metals and alloys. The program is based on an interdisciplinary approach designed to interrelate the factors of early fatigue damage with measurable physical phenomena. The program initially concentrated on a comprehensive study of the existing knowledge of fatigue phenoma in metals, and the results of the study are described in terms of fatigue and fatigue-associated phenomena, metallurgical structure, effect of interrelating fatigue phenomena on physical properties, and the availability of appropriate measurement techniques and equipment. Next, the program developed a series of controlled fatigue experiments to quantitatively measure the fatigue effects in selected metal specimens. These tests also included a systematic metallographic evaluation to determine the actual depth and character of the surface layer affected by progressive fatigue, particularly in the early stages of fatigue. Finally, NDT methods were evaluated in terms of their potential detection and measurement capability of the observed fatigue-related effects and damage as determined by the study and fatigue evaluation tests.

Fatigue Test and Analysis of the F-100 Landing Gear. Volume I ( Book )
1 edition published in 1969 in English and held by 1 library worldwide
A static strength analysis is performed using revised and up-dated ground loads for the new F-100 landing gear, as redesigned under the direction of OOAMA, Hill Air Force Base, Ogden, Utah. No zero or negative margins of safety are found. The fatigue life of the redesigned portions of the gear is found to meet the requirement of 7,000 hours of trouble free service upon the basis of the results of full scale fatigue tests. A computer program using Miner's Rule is used to predict the laboratory fatigue failures which did occur as well as to predict a service life for sections not having a laboratory failure history. Strain gages and photostress were used to obtain experimental stress concentration factors
In-Place Tube Welding Manufacturing Technology ( Book )
1 edition published in 1971 in English and held by 1 library worldwide
A welding system, comprising a weld tool and a programer control unit, was designed, fabricated, and tested. The system is capable of producing consistent aircraft quality butt welds in 1/2-inch diameter by 0.035-inch wall and 1-inch diameter by 0.070-inch wall 6Al-4V titanium alloy tubing. Test specimens in these tube sizes have been welded and tested in flexure fatigue, impulse cycled and ultimate burst pressure tested at 500F. The test results indicate this tube joining technique to be equal or superior to any other method available for service conditions of 4,000 psi working pressure and 500F temperature. (Author)

The Influence of Oxygen Concentration on the Internal Stress and Dislocation Arrangements in Alpha Titanium ( Book )
1 edition published in 1970 in English and held by 1 library worldwide
The long range and thermally activated components of the flow stress in alpha-Ti have been measured by a stress relaxation technique. Materials containing five different levels of oxygen, ranging from 250-5200 weight ppm were studied over the temperature range 200K-550K. The dislocation arrangements after relaxation have also been studied using thin foil electron microscopy techniques. In the higher oxygen materials it has been found that the internal stress varies more strongly with temperature than would be predicted by the temperature dependence of the elastic modulus; simultaneously, the thermally activated component of the flow stress goes through a maximum at the temperature where the internal stress becomes strongly temperature dependent. Thin foil results show that the maximum flow stress and rise of internal stress correspond to the onset of coplanar slip. An attempt to qualitatively rationalize this behavior is also made. (Author)
Nuclear Effects Analysis D1-S-1800 Aerial Radiac System AN/ADR-6(XE-4) (V) ( Book )
1 edition published in 1972 in English and held by 1 library worldwide
This preliminary report summarizes the analysis effort performed to date on the Aerial Radiac System (ARS) to assure proper ARS operation following exposure to nuclear radiation. To facilitate the analysis effort, the ARS has been subdivided into several subcircuits. Each subcircuit will be analyzed and/or tested to assure proper performance following exposure to radiation at specification level. The ARS is used to measure ground dose radiation level (Rads/hr). The Power Supplies convert aircraft 28 volts dc to regulated +15 and -15 volts dc and -1000 volts dc. Gamma dose rate is measured by the Photomultiplier Tube and converted to a voltage level by a log amplifier. This voltage when scaled by EMAX in the subtractor circuit becomes the air dose level. The Ground Dose Computer provides the ground dose level by combining a signal proportional to the altitude as furnished by a radar altimeter with the air dose level signal. The ground dose level signal is displayed, recorded and/or can be telemetered. A self test feature is also provided
Life Support Systems Requirements. Volume I. Section I. System Analysis ( Book )
1 edition published in 1970 in English and held by 1 library worldwide
The volume includes the system engineering analysis as applied to the development of life support system requirements. This effort was directed at operationally defining basic analytic objectives through the identification of fundemental system constraints and developing appropriate methodologies for the derivation, documentation, and implementation of basic life support requirements. The analyses presented translate basic system requirements into detail life support system functional requirements for air vehicle/mission and support operations. (Author)

A Study of Dislocation: Hydrogen Interaction in Titanium Aluminum Alloys via Internal Friction Measurements ( Book )
1 edition published in 1972 in English and held by 1 library worldwide
Hydrogen-dislocation interactions in alpha titanium-aluminum alloys were studied via internal friction measurements in the temperature range 200K to 500K. Employing a series of titanium-aluminum binary alloys (0 %, 1 at. % and 3 at. %Al) these interactions were monitored in terms of observation of a damping peak which centers around 390 K at 10 MHz. The activation energy and attempt frequency of the damping peak in pure titanium were found to be 0.28 eV and 4x10 to the 10th power/sec, respectively. Both room temperature plastic deformation and the presence of hydrogen are required to generate this peak. The relaxation strength of the peak in each of the alloys increases at this peak. The relaxation strength of the peak in each of the alloys increases at low hydrogen levels with the square of hydrogen concentration and reaches a plateau when a critical hydrogen concentration is attained.

Fatigue Test and Analysis of the F-100 Landing Gear. Volume III ( Book )
1 edition published in 1969 in English and held by 1 library worldwide
The F-100 Aircraft Structural Integrity Program was designed to fatigue test the basic wing, fuselage and empennage structure of the air vehicle. In conjunction with these tests, actual nose and main gears were used as loading jigs to introduce ground loads into the structure. Consequently, the major portion of the test effort on the landing gear was completed on that program. The incomplete testing of the nose gear was concluded on the F-100 Landing Gear Fatigue Test Program. The results of the gear tests conducted on both programs are presented in this section of the report

Propulsion System Flow Stability Program (Dynamic). Part XI. Lift Engine Compressor Tests and Response to Steady-State Distortion ( Book )
1 edition published in 1968 in English and held by 1 library worldwide
A four-stage lift engine type compressor was tested over its complete operating range with and without combined circumferential and radial distortion of inlet total pressure. The compressor rig was equipped with interstage instrumentation at each rotor exit and the test procedure was such that a circumferential and radial survey of interstage data were obtained at each test point. Analysis of the data showed that interstage flow mixing and distortion attenuation was related to the slope of the characteristics of the individual stages. Detailed observations of the interstage data are presented which provide considerable insight into distorted compressor operation. A simple analytical procedure to describe compressor events is proposed. Recommendations are made for additional analytical and empirical investigations to corroborate the analysis and conclusions.

Relaxation Processes in Metastable Beta Titanium Alloys ( Book )
1 edition published in 1971 in English and held by 1 library worldwide
Extensive observations have been made on an internal friction peak in a series of metastable beta Ti-Mo and -V alloys. The peak was observed at two frequencies (10 to the 4th c/s and 10 to the 7th c/s) in temperature ranges of 120K to 140K and 153K to 210+K respectively depending on alloy compositions as well as frequency. In both alloy systems, the peak strength passed through a maximum with increasing alloy content at or near the upper compositional bound for athermal omega formation. In both alloy systems, the peak persisted at compositions well above the upper compositional bound for athermal omega formation although it was greatly diminished in height. The peak's strength was severely reduced by annealing in the thermal omega precipitation temperature range. The results of the work will be compared to the properties of a similar internal friction peak reported earlier in Zr base alloys. (Author)
