Vibration characteristics of the HPOTP (High Pressure Oxygen Turbopump) of the SSME (Space Shuttle Main Engine)

A review is presented of various rotordynamic problems which have been encountered and eliminated in developing the current flight engines, and continuing subsynchronous problems which are being encountered in developing a 109% power level engine. The basic model for the High Pressure Oxygen Turbopump (HPOTP) of the SSME including the structural dynamic model for the rotor and housing and component models for the liquid and gas seals, turbine-clearance excitation forces, and impeller-diffuser forces are discussed. Results from a linear model are used to examine the synchronous response and stability characteristics of the HPOTP, examining bearing load and stability problems associated with the second critical speed. Various seal modifications are examined and shown to have favorable consequences with respect to bearing reactions and stability

Transfer molding of PMR-15 polyimide resin

Transfer molding is an economically viable method of producing small shapes of PMR-15 polyimide. It is shown that with regard to flexural, compressive, and tribological properties transfer-molded PMR-15 polyimide is essentially equivalent to PMR-15 polyimide produced by the more common method of compression molding. Minor variations in anisotropy are predictable effects of molding design and secondary finishing operations

Blessed Are the Peacemakers: The Future Burden of Intrastate Conflict on Poverty

Intrastate conflict generally undermines human development but its effect on global poverty across different income thresholds remains poorly understood. This paper analyzes how many people will live in poverty due to intrastate civil conflict in 2030, 2050, and 2070 using the International Futures model and shared socioeconomic pathways, forecasting 12 scenarios for 179 countries. A baseline conflict scenario leads to an additional 148.2 million (range: 50.7 to 186.0 million) people living in extreme poverty (\u3c$1.90 per day) due to conflict by 2030 compared with a scenario where conflict is eliminated starting in 2022. These conflict-attributable poor represent 20.1% of the population in extreme poverty at that time, with the majority living in South Asia followed by Africa. By 2050 the population living in conflict-attributable poverty increases to 164.9 million (range: 4.4 to 376.5 million), representing 32.7% of the total extremely poor population at that time with the majority living in Africa. While future conflict will be responsible for hundreds of millions of people living in poverty, its elimination is not a panacea for achieving development targets: even in a scenario with no intrastate conflict from 2022 to 2030 the population living in extreme poverty is projected to be 6.9%, well above the target threshold of 3% for achieving the first Sustainable Development Goal

Free Will\u27s Enormous Cost: Why Retribution, Grounded in Free Will, is an Invalid and Impractical Penal Goal

The lack of free will in human experience causes clear problems for criminal punishment. Free will is a central assumption of retribution; without the free choice to tear the moral fabric of society, one’s actions cannot warrant that she receives punishment. For its invalidity and cost, retribution should not be used as a penological goal in the creation of laws or sentencing. Utilitarian goals, aimed at the social good, should be used in retribution’s place

The Textual Architecture of Empire in Two Early Qing Anthologies

During the first half century of the Qing dynasty, Manchu emperors commissioned massive publication projects on the Chinese classics. In early Qing interpretations of classics on the family, negotiations between Manchu and Han family and gender norms furthered the empire-building project. This article compares the spatial form of the Yuding Nei ze yanyi 御定内則衍義 (1656), an expansion of the “Inner Standards” chapter of the Classic of Rites commissioned by the Shunzhi emperor, to that of the Yuding Xiao jing yanyi 御定孝經衍義 (1682), an expansion of the Classic of Filial Piety commissioned by the Kangxi emperor. These works are textual spaces where the cultural and political negotiations of the early Qing empire play out; they use spatial strategies of juxtaposition and hierarchy to balance different messages for different constituencies, creating textual models of empire

Effects of Ultra-Clean and centrifugal filtration on rolling-element bearing life

Fatigue tests were conducted on groups of 65-millimeter bore diameter deep-groove ball bearings in a MIL-L-23699 lubricant under two levels of filtration. In one test series, the oil cleanliness was maintained at an exceptionally high level (better than a class "000" per NAS 1638) with a 3 micron absolute barrier filter. These tests were intended to determine the "upper limit" in bearing life under the strictest possible lubricant cleanliness conditions. In the tests using a centrifugal oil filter, contaminants of the type found in aircraft engine filters were injected into the filters' supply line at 125 milligrams per bearing-hour. "Ultra-clean" lubrication produced bearing fatigue lives that were approximately twice that obtained in previous tests with contaminated oil using 3 micron absolute filtration and approximately three times that obtained with 49 micron filtration. It was also observed that the centrifugal oil filter had approximately the same effectiveness as a 30 micron absolute filter in preventing bearing surface damage
