Aerodynamic, structural, and trajectory analysis of ASTRID-1 vehicle (open access)

Aerodynamic, structural, and trajectory analysis of ASTRID-1 vehicle

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) …

[Letter from I. H. Kempner to Messrs. Westheimer & Company, May 10, 1949]

Letter from I. H. Kempner to Milton F. Westheimer and other unnamed associates requesting current information on stocks and the prices that they're being sold for, as he was told that the book price for the stocks was higher than what they were actually being sold for and would subsequently like to confirm this information. Kempner also expresses how he would like to meet with the Westheimers again on his next trip, as well as expressing his high hopes that tax laws will not be discussed in Congress.

Search for the microscopic origin of defects and shear localization in metallic glasses (open access)

Search for the microscopic origin of defects and shear localization in metallic glasses

This proposed research addresses one of the long outstanding fundamental problems in materials science, the mechanisms of deformation in amorphous metals. Due to the lack of long-range translational order, details of structural defects and their behaviors in metallic glasses have not been accessible in experiments. In addition, the small dimensions of the amorphous alloys made early by rapid quenching impose severe limit on many standard mechanical and microscopy testing. As a result, the microscopic mechanism of deformation in the amorphous materials has not been established. The recent success in synthesis of bulk metallic glass overcomes the difficulty in standard testing; but the barrier for understanding the defect process and microscopic mechanisms of deformation still remains. Amorphous metals deform in a unique way by shear banding. As a result, there is no work hardening, little macroscopic plasticity, and catastrophic failure. To retain and improve the inherent high strength, large elastic strain, and high toughness in amorphous metals, a variety of synthesis activities are currently underway including making metallic glass matrix composites. These new explorations call for a quantitative understanding of deformation mechanisms in both the monolithic metallic glasses as well as their composites. The knowledge is expected to give insight and …

Oral History Interview with Alan Pilot, August 10, 2010 transcript

Oral History Interview with Alan Pilot, August 10, 2010

The National Museum of the Pacific War presents an oral interview with Alan Pilot. Pilot joined the Army in January 1943 and received basic training at Camp Howze. He received further training in Louisiana for the European Theater and then in California for the Pacific Theater. In January he left for Camp Old Gold at La Havre, where he served as a combat medic, supporting Companies E, G, and H of the 343rd Infantry, 86th Division. His unit relieved the 8th Division and fought in Cologne, where he was stationed at the top of the cathedral while it was being shelled. In the Ruhr Pocket a defective shell landed 10 feet away from him. He recalls seeing 100,000 Germans surrender there. He describes the Bavarian people as friendly as he passed through Austria on VE Day. He was then sent to the Pacific as part of Operation Coronet. VJ Day came while he was still crossing the Pacific. He spent the last five months of his service in the Philippines at a quiet outpost while the rest of his unit prepared the Philippines for independence. Pilot returned home and was discharged in January 1946.
