Solar wind iron abundance variations at solar wind speeds > 600 km s/sup -1/, 1972 to 1976

Description: We have analyzed the Fe/H ratios in the peaks of high speed streams (HSS) during the decline of Solar Cycle 20 and the following minimum (October 1972 to December 1976). We utilized the response of the 50 to 200 keV ion channel of the APL/JHU energetic particle experiment (EPE) onIMP-7 and 8 to solar wind iron ions at high solar wind speeds (V greater than or equal to 600 km sec/sup -1/), and compared our Fe measurements with solar wind H and He parameters from the Los Alamos National Laborator… more

Fact sheets relating to use of geothermal energy in the United States

Description: A compilation of data relating to geothermal energy in each of the 50 states is presented. The data are summarized on one page for each state. All summary data sheets use a common format. Following the summary data sheet there are additional data on the geology of each state pertaining to possible hydrothermal/geothermal resources. Also there is a list of some of the reports available pertaining to the state and state energy contacts. The intent of these documents is to present in a concise for… more

Reentry response of the light weight radioisotope heater unit resulting from a Venus-Earth-Earth Gravity Assist maneuver accident

Description: Reentry analyses consisting of ablation response, thermal response and thermal stress response have been conducted on the Light Weight Radioisotope Heater Unit for Galileo/VEEGA reentry conditions. Sequential ablation analyses of the LWRHU aeroshell, the fuel clad, and the fuel pellet have been conducted in reentry regimes where the aeroshell has been deemed to fail. The failure criterion for ablation is assumed to be recession corresponding to 50% of the wall thickness (the design criterion re… more

Potential application of Madison formation waters for community heating in South Dakota

Description: It is suggested that the most practical early application of the Madison waters is in community space heating with the local hot waters considered as a municipal commodity. The general design of such a community system is discussed along with its cost, means of financing, and life expectancy. Legal questions and state statutes that are pertinent are cited and the life expectancy of the entire Madison resource and equipment to expoit the resource are considered. (MHR)

Follow-up investigations of GPHS motion during heat pulse intervals of reentries from gravity-assist trajectories. Aerospace Nuclear Safety Program

Description: Motion studies of the General Purpose Heat Source Module, GPHS, which were conducted in the heat pulse intervals associated with entries from earth gravity assist trajectories. The APL six-degree-of-freedom reentry program designated TMAGRA6C was used. The objectives of the studies were to (1) determine whether the GPHS module entering the earth`s atmosphere from an earth-gravity-assist trajectory has a preferred orientation during the heat pulse of reentry, (2) determine the effect of magnus f… more

Compilation and Correlation of Experimental, Hypersonic, Stagnation Point Convective Heating Rates

Description: Experimental shock-tube data for the aerodynamic heating at the stagnation point on spherical bodies at superorbital and suborbital flight velocities (U/sub/0) have been compiled from a number of sources and compared to theoretical predictions. It was found that the empirical correlation given by Detra, Kemp and Riddell is remarkably close to a least-squares fit of the data. It is therefore recommended that their correlation be used for continuum flow theoretical predictions of the laminar hype… more
