|
| Summarizes work performed by McDonnell Douglas Aerospace on a contract under the ARPA University-Industry ATR Initiative. The focus is on a preliminary investigation into the use of wavelets to extract local feature points to be used for matching 2-D and 3-D structure in multiple images. The approach is to detect dominant local discontinuities (i.e., point features, corners, curvature discontinuities) as a function of wavelet coefficients. |

|
| Estimates of the cost of providing training, in forms ranging from classroom instruction to on-the-job training, are needed to support decisions about who gets trained, when, where, and on what skills. To counter the myriad of uncontrollable factors that may obscure the relationship between manpower, personnel, and training policy changes and organizational outcomes, an organizational simulation of Air Force occupations called the Training Impact Decisions System (TIDES) was developed.

| The Air Force Air Logistics Centers (ALCs) have either recently eliminated or have plans to eliminate the usage of cadmium processing for the maintenance and overhaul of aircraft. The thrust of their effort is the elimination of the hazardous cadmium waste streams. The replacement process, ion vapor deposition (IVD) of aluminum, is free of the environmental problems associated with cadmium processing. However, as for cadmium processing, it still requires subsequent ... |

|
| Efforts to develop electrically conducting thermoset polymers in which the pi-conjugation extends along the backbone and through the crosslink are described. Hot/melt processing of the monomers and oligomers was used to form the thermosets. Three different approaches were used to get the thermoset polymers conducting. The acetylene-terminated Schiff base and acetylene- terminated polythiophene monomers were first cured, then doped with iodine, whereas the acetylene-terminated polyaniline oligomers were first doped with ... |

| The Viscous Effects On Complex Configurations (VECC) program was a three task effort to improve preliminary aerodynamic prediction and analysis on high speed, arbitrary-shaped configurations. The first task was to incorporate a Newtonian streamline tracing code, 'QUADSTREAM', into a Graphical User Interface (GUl) system. The second task consisted of upgrades to the Supersonic-Hypersonic Arbitrary Body Program (SHABP). The third task, Pre-/Post-Processing, encompassed the development of the geometry modeling/display module, SHABP ... |

| The objective of this work has been to develop a direct numerical simulation capability for compressible, non-canonical wall-bounded flows which is directly applicable to actual flight vehicles. Data from the simulations is used to educe information about the organized motion. In the flow and bow they are affected by the extra strain rates due to concave wall curvature. A second- order finite volume approach and both fourth-order and sixth-order compact ... |

|
| Spectral measurements of the limb radiation of the earth have shown that emissions from the NO(v=1) and CO2(0l (1)0) states dominate the nighttime radiance seen at long wavelengths. At the high altitudes of the thermosphere, the deactivation of the aforementioned molecules helps regulate the temperature. A knowledge of the kinetics of deactivation of these molecules is therefore needed to accurately model the temperature of the thermosphere. Sharma and coworkers have ... |

| A set of aircraft maneuvers has been developed to augment evaluation maneuvers used currently by the flying qualities and flight test communities. These maneuvers extend evaluation to full aircraft dynamics throughout the aircraft flight envelope. As a result, a tie has been established between operational use and design parameters without losing control of the aircraft evaluation process. Twenty maneuvers are described as an initial set to examine primarily high-angle-of attack ... |

| In missile preliminary design it is necessary to quickly and economically estimate the aerodynamics of a wide variety of missile configuration designs. Since the ultimate shape and aerodynamic performance are so dependent upon the subsystems utilized, such as payload size, propulsion system selection and launch mechanism, the designer must be capable of predicting a wide variety of configurations accurately. The fundamental purpose of Missile Datcom is to provide an aerodynamic ... |

|
| The primary objective of this study is to determine experimentally the receptivity of a laminar boundary layer to convected gusts. Receptivity is the process by which external disturbances transfer energy to instabilities in the boundary layer. The term convected gust refers to a transient or periodic vortical disturbance convected by the freestream. The experimental approach consisted of hot-wire studies of the boundary layer response to vortical disturbances produced by an ... |
