Research rocket test RR-1 (Black Brant VC) and RR-2 (Aerobee 170A): Investigations of the stability of bubbles in plain and fiber-reinforced metal and solidified in a near-zero-g environment

The results of the first two of a series of research rocket flights are presented. The objectives of these flights were (1) to learn about the capabilities of these rockets, (2) to learn how to interface the payloads and rockets, and (3) to process some of the composite casting demonstration capsules intended originally for Apollo 15. The capsules contained experiments for investigating the stability of gas bubbles in plain and fiber-reinforced metal melted and solidified in a near-zero-g (0.0119g) environment. The characteristics of the two research rockets, an Aerobee 170A and a Black Brant VC, used to obtain the periods of near-zero-g and the temperature control unit used for processing the contents of the two experiment capsules are discussed

The Panel in Context: An Introduction to The Talented Mr. Ripley

This introduction provides a context for the transcript of the panel discussion on The Faction’s production of The Talented Mr. Ripley that took place at London’s New Diorama Theatre in February 2015.1 The event was organized jointly by The Faction and Caroline Bainbridge and Candida Yates, Directors of the Media and Inner World research network. The network was first set up and funded by the AHRC in 2009 with the aim to create a dialogue between academics, media practitioners and creative and psychoanalysts and psychotherapists to explore the role of emotion and unconscious processes in the spheres of both practice and representation within media and culture. Caroline Bainbridge and I have worked with The Faction on a number of occasions, and, in the case of The Talented Mr. Ripley, we also worked with the cast in rehearsals as consultants. This involved focusing on the psychoanalytic themes of the text whilst also using a process consultancy method to explore the relational and affective themes that emerged within rehearsals themselves

Developments in steady and unsteady aerodynamics for use in aeroelastic analysis and design

A review is given of seven research projects which are aimed at improving the generality, accuracy, and computational efficiency of steady and unsteady aerodynamic theory for use in aeroelastic analysis and design. These projects indicate three major thrusts of current research efforts: (1) more realistic representation of steady and unsteady subsonic and supersonic loads on aircraft configurations of general shape with emphasis on structural-design applications, (2) unsteady aerodynamics for application in active-controls analyses, and (3) unsteady aerodynamics for the frequently critical transonic speed range. The review of each project includes theoretical background, description of capabilities, results of application, current status, and plans for further development and use

The M. W. Burks Site (41WD52): A Late Caddo Hamlet in Wood County, Texas

While attempting to locate and evaluate prehistoric Caddo archaeological sites in the Dry Creek watershed, Wood County, Texas, that had been originally recorded by A. T. Jackson and M. M. Reese in 1930, the M. W. Burks site (41WD52) was discovered by James E. Bruseth and Bob D. Skiles in June 1977. The site is in the Forest Hill community, about 5 km north of Quitman, Texas, in the East Texas Pineywoods and Gulf Coastal Plain. It is on a small rise in the uplands overlooking a small intermittent drainage that is an unnamed tributary of Little Dry Creek. The landowner, Mr. M. W. Burks, had resided in this part of Wood County since the 1920s, and recalled where A. T. Jackson and crew had spent time excavating the J. H. Reese (41WD2) site. He mentioned that while putting in a fence on his property in the early 1960s, adjacent to the property where the Reese site is located, he had found some pottery sherds in one of the post holes. Bruseth and Skiles placed a small shovel test next to this fence post hole, and a large articulated red-slipped Ripley Engraved carinated bowl was encountered at 65 em below the surface (bs) in tan sand E-horizon deposits. This find demonstrated that the Burks site contained both intact archaeological deposits as well as an apparently undisturbed Late Caddo Titus phase burial or cemetery. Bruseth, Skiles, and Perttula followed up this work with more intensive investigations in the spring and fall of 1978. This research was carried on as an adjunct to the ongoing (and final season of) archaeological work being conducted by Bruseth and Perttula at Lake Fork Reservoir on Lake Fork Creek, a few miles to the west of the Burks site. Our purpose in carrying out archaeological research at the Burks site was to examine in more detail the spatial character of a Late Caddo Titus phase settlement, and also obtain information on the material culture remains (especially the ceramics) made and used by the Caddo peoples that lived at the Burks site some 400-500 years ago

Geometry requirements for unsteady aerodynamics in aeroelastic analysis and design

Aircraft geometry requirements for unsteady aerodynamic computations are discussed and differences between requirements for steady and unsteady flow are emphasized within the framework of a general potential-flow aerodynamic formulation. Its implementation in a computer program called SOUSSA (Steady, Oscillatory, and Unsteady Subsonic and Supersonic Aerodynamic is detailed
