The Johns Hopkins University/Applied Physics Laboratory, JHU/API, in support of Lawrence Livermore National Laboratory, LLNL, is conducting aerodynamic, trajectory, and structural analysis of the Advanced Single Stage Technology Rapid Insertion Demonstration (ASTRID) vehicle, being launched out of Vandenberg Air Force Base (VAFB) in February 1994. The launch is designated ASTRID-1 and is the first in a series of three that will be launched out of VAFB. Launch dates for the next two flights have not been identified, but they are scheduled for the 1994-1995 time frame. The primary goal of the ASTRID-1 flight is to test the LLNL light weight thrust on demand bi-propellant pumped divert propulsion system. The system is employed as the main thrusters for the ASTRID-1 vehicle and uses hydrazine as the mono-propellant. The major conclusions are: (1) The vehicle is very stable throughout flight (stability margin = 17 to 24 inches); (2) The aerodynamic frequency and the roll rate are such that pitch-roll interactions will be small; (3) The high stability margin combined with the high launcher elevation angle makes the vehicle flight path highly sensitive to perturbations during the initial phase of flight, i.e., during the first second of flight after leaving the rail; (4) …

The Johns Hopkins University Applied Physics Laboratory, under contracts with several agencies of the federal government and an agency of the State of Maryland, is engaged in developing energy resources, utilization concepts, and monitoring and storage methods. This Quarterly Report summarizes the work on the various tasks as of 30 June 1980. The Energy Quarterly Report is divided into three sections. The first, Geothermal Energy Development Planning and Technical Assistance, supported by the Department of Energy/Division of Geothermal Energy (DOE/DGE), contains reports on the progress of geothermal-related tasks on which effort was concentrated during the quarter. The second section, Operational Research, Hydroelectric Power Development, supported by the Department of Energy/Resource Applications (DOE/RA), contains reports on small-scale hydroelectric investigations in the southeastern states. The third section, Energy Conversion and Storage Techniques, contains three articles. The first is on data analysis of OTEC core unit condenser tests, and is supported by the Department of Energy/Division of Central Solar Technology (DOE/CST). The second is on the current status of the Community Annual Storage Energy System at the U.S. Naval Air Station, Norfolk, Va., and is supported by the Department of Energy and the Department of Defense, Naval Facilities Engineering Command/Atlantic Division. The third …

The Johns Hopkins University Applied Physics Laboratory, under contracts with several agencies of the federal government and an agency of the State of Maryland, is engaged in developing energy resources, utilization concepts, and storage methods. This Quarterly Report summarizes the work on the various tasks as of 31 December 1979. The Energy Quarterly Report is divided into five sections. The first, Geothermal Energy Development Planning and Technical Assistance, supported by the Department of Energy/Resource Applications (DOE/RA), contains reports on the progress of those geothermal-related tasks where effort was concentrated during the quarter. The second section, Operational Research, Hydroelectric Power Development, also supported by DOE/RA, contains reports on small-scale hydroelectric investigations in the southeastern states. The third section, Seismotectonic Studies, supported by the Reactor Safety Research Division of the Nuclear Regulatory Commission, reports on neotectonic investigations in Connecticut. The fourth section, Energy Conversion and Storage Techniques, contains two articles, the first on OTEC core unit testing supported by the Department of Energy, Division of Central Solar Technology (DOE/CST), and the second on recovery of landfill methane, supported by the Argonne National Laboratory. The fifth section, New Energy Technologies, reports on Laboratory studies of an unconventional gas source--Eastern Devonian shales.

Letter from J. C. Jefferies, a staff veterinarian at the Hyattsville (Maryland) Station writing to Wendell Tarver, a veterinary trainee expressing appreciation for the work that Tarver had done for their Swine Diseases department and the materials that he had prepared for them.

Photograph of thirteen men wearing suits, posing together at a veterinarian administrator conference. Four men are seated behind a table and have namecards in front of them; the other nine men are standing in a line behind them. In the left side of the image, a a poster on an easel is partially visible, labeled "How to Get the Most Out of a Conference." Printed text at the bottom of the photo: "13th Conference, Veterinarian Administrator Development Program. May 22-26, 1967. Hyattsville, Md."

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 hypersonic convective stagnation-point heating rate to spherical bodies in the region U/sub/0 - 6000 to 58,000 ft/sec.
