Damping degradation in incramute and sonoston due to low temperature storage.
Two commercial manganese-copper based alloys, SONOSTON and INCRAMUTE, were evaluated for their ability to maintain optimum damping capacity with time when stored at room temperature and 100°C, which represents a temperature ...
The effects of an embedded vortex on a film cooled turbulent boundary layer.
This study was designed to model some of the secondary flow effects on endwalls, blades, and combustion chambers of gas turbine engines. Measurements were made in a turbulent boundary layer developing over a flat plate, ...
Stability of the vortex motion in oscillating flow.
Previous experimental investigations have shown that the characteristics of flow about a circular cylinder immersed in a time-dependent flow exhibit cycle-to-cycle variations. These variations have been attributed to the ...
Modeling and experimental validation of a single-link flexible manipulator.
Structural flexibility effects on robot mechanisms is a very important consideration in the move toward lighter, faster, and more accurate robot systems. This thesis presents the computer simulation and experimental ...
Microcomputer control of a hydraulic power element
The Navy uses electrohydraulic servomechanisms throughout the fleet in the control of vehicles, weapons, and platforms. Better understanding of how these systems work will lead to ways of improving their performance, ...
Marine gas turbine modeling for modern control design
The search for improved performance of U.S. Navy ships has led to more complex propulsion systems consisting of multiple, interacting inputs. Classical control theory does not effectively exploit these interactions. Modern ...
The variation of subgrain misorientation in aluminum with large steady-state creep strain
High purity aluminum was torsionally deformed to various strains up to 16.33 at a temperature of 644 K in this study. The variation in the dislocation substructure was determined with increasing strain. Recent work revealed ...
Nucleate pool-boiling of R-114 refrigerant and oil mixtures from water-heated enhanced surfaces
Heat- transfer measurements were made for a single, water-heated tube in a pool of R-114 to simulate operating conditions of a water chiller. Data were obtained for a smooth copper tube, and for two commercially ...
A parametric study of elastic response of submarine-installed equipment subjected to UNDEX side-on loading
It is desirable to perform a study of the elastic responses of submarine hulls and internally attached structures to underwater shock loading. In view of the expense and possible involvement of non-shock testable equipment ...
An investigation into the tripping behavior of longitudinally T-stiffened rectangular flat plates loaded statically and impulsively
An experimental investigation was conducted to determine the static and dynamic responses of a specific stiffened flat plate design. The air-backed rectangular flat plates of 6061-T6 aluminum with an externally machined ...
