Impact of flying qualities on mission effectiveness for helicopter air combat, volume 1

A computer simulation to investigate the impact of flying qualities on mission effectiveness is described. The objective of the study was to relate the effects of flying qualities, such as precision of flight path control and pilot workload, to the ability of a single Scout helicopter, or helicopter team, to accomplish a specified anti-armor mission successfully. The model of the actual engagement is a Monte Carlo simulation that has the capability to assess the effects of helicopter characteristics, numbers, tactics and weaponization on the force's ability to accomplish a specific mission against a specified threat as a function of realistic tactical factors. A key feature of this program is a simulation of micro-terrain features and their effects on detection, exposure, and masking for nap-of-the-earth (NOE) flight

Multicolor pyrometer for materials processing in space

The program goals are to design, construct, and program a prototype imaging pyrometer capable of measuring the temperature distribution across the surface of a moving object suspended in space. The approach is to utilize an optical system which operates at short wavelengths compared to the peak of the blackbody spectrum for the temperature range of interest, thus minimizing errors associated with a lack of knowledge about heated sample emissivity. An analysis of the system's temperature measurement capability based on the camera's responsivity was performed and bound to be satisfactory. Details for the evolving optical design and the progress towards construction of a working model are discussed. Details of the algorithm developed for selecting the optimum colors to be used by the pyrometer are reported. Though final selection of the colors will have to await a final design of the optical system, results using a preliminary optical design are presented

Governor Bernardo de Galvez's New Orleans Belle : Felicitas de ST. Maxent

El ilustre soldado Bernardo de Gálvez nació en 1746 en el pueblo malagueño de Macharaviaya. Sirvió en la invasión de Argel en 1775 y al año fue destinado a Nueva Orleans donde casó con la criolla Felicitas de St. Maxent. Al terminar la guerra de 1783 el matrimonio regresó por un año a la península. Fue ascendido a virrey de México en 1785 donde murió al año. La viuda Felicitas regreso a España con sus cuatro hijos convirtiendo su palacete en Madrid en tertulia de los ilustrados de la capital, incluyendo al Conde de Aranda y Cabarrús, Sabatini, Moratín, etc. Fue desterrada en 1790 por dos años a Valladolid y Zaragoza por orden de la Reina María Luisa y Godoy. Murió en Aranjuez en 1799

THE EFFECTS OF FINITE-RATE REACTIONS AT THE GAS/SURFACE INTERFACE IN SUPPORT OF THERMAL PROTECTION SYSTEM DESIGN

Gas-surface modeling is dependent on material type and atmospheric reentry conditions. Lower molecular collisions at the low pressure trajectories make it more likely for occurrences of nonequilibrium, or finite-rate, reactions. Equilibrium is often assumed at the surface of a material as it is a subset of nonequilibrium and is easier to compute, though it can lead to overly conservative predictions. A case where a low density material experiences a low pressure trajectory and designed for equilibrium is the Stardust Return Capsule (SRC) with the Phenolic Impregnated Carbon Ablator (PICA) as its heatshield. Post-flight analysis of the recession on the SRC found that the prediction from the equilibrium model can be more than 50% larger than the measured recession. The Modified Park Model was chosen as the finite-rate model as it contains simple four reactions (oxidation, sublimation, and nitridation) and has been previously used to study individual points of the SRC trajectory. The Modified Park Model cannot model equilibrium so a model BFIAT was developed that allows finite-rate reactions to be applied to the surface for a certain length of time. Finite-rate sublimation was determined to be reaction of importance in the Park Model for SRC-like conditions. The predicted recession on the SRC heatshield experienced a reduction in its overprediction; the finite-rate predictions fall with the measurement error of the recession at three points on the heatshield. The recession reduction was driven by a significant reduction in char formation. There was little change in the pyrolysis gas rate. The finite-rate model was also applied to simulations of various arc-jet tests that covered a range of heating conditions on the surface of the PICA material. Comparison to this experimental data further showed the role of finite-rate reactions and sublimation in the Park Model and conditions that favor the nonequilibrium assumption (heating over 1000 W/cm2). For the emerging PICA material, used for the Mars Science Laboratory and one of two material choices for the Crew Exploration Vehicle, and SRC-like trajectories, a finite-rate model was developed such that the more robust nonequilibrium assumption can be applied to design processes to reduce heatshield mass

Containing Fatness: Bodies, Motherhood, and Civic Identity in Contemporary U.S. Culture

The body, and visualizations of the body, serve as a way read appropriate consumption and citizenship: Weight operates as a key way to see literal consumption. U.S. citizenship is now commonly understood as consumptive bodily citizenship, where one\u27s body, or one\u27s child\u27s body, communicates their civic standing. Drawing on three case studies concerning childhood obesity, this dissertation demonstrates how rhetorics of and about the fat body construct the public identity of good citizen and good mother
