Book Synopsis Thermal Modeling, Analysis, and Control of a Space Suit by : Anthony Bruce Campbell
Download or read book Thermal Modeling, Analysis, and Control of a Space Suit written by Anthony Bruce Campbell and published by . This book was released on 1999 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The thermal dynamics of two space suits, the Space Shuttle EMU and the MPLSS Advanced Space Suit, are considered as they relate to astronaut thermal comfort control. The activities documented in this dissertation cover three related areas, modeling, analysis, and control. A detailed dynamic lumped capacitance thermal model of the operational Space Shuttle EMU is used to analyze the thermal dynamics of the system with observations verified using experimental and flight data. Prior to using the model to define performance characteristics and limitations for the space suit, the model is first evaluated and improved. This evaluation includes determining the effect of various model parameters on model performance and quantifying various temperature prediction errors in terms of heat transfer and heat storage. The thermal dynamics and design of an Advanced Space Suit are next considered. A transient model of the MPLSS Advanced Space Suit design is developed and implemented using MATLAB/Simulink, to help with sizing, with design evaluation, and with the development of an automatic thermal comfort control strategy. The model is described and the thermal characteristics of the Advanced Space Suit are investigated including various parametric design studies. The steady state performance envelope for the Advanced Space Suit is defined in terms of the thermal environment and human metabolic rate and the transient response of the human-suit-MPLSS system is analyzed. The observations and insights about the thermal dynamics of a space suit are then applied to the automatic thermal comfort control of the MPLSS Advanced Space Suit. Automatic thermal comfort control for the Advanced Space Suit is investigated using three proposed strategies. These strategies use a transient thermal comfort definition based on body heat storage. The first strategy is measurement based using a proposed body heat storage estimation method to determine the astronaut's thermal state. The second strategy is model based using a model to determine the desired liquid cooling garment inlet temperature to provide thermal comfort. The third strategy is a hybrid strategy combining the measurement based and model based approach using the Generalized Predictive Control framework. Each strategy then uses a resource allocation decision logic to determine which of three control mechanisms to use so that thermal comfort can be provided while minimizing the use of consumables. Accuracy and performance of the strategies are evaluated using simulations, highlighting their advantages and limitations."--Leaves iv-v.
Book Synopsis Analysis of Nonuniform Suit Temperatures for Space Suits in Orbit by : Kenneth R. Cramer
Download or read book Analysis of Nonuniform Suit Temperatures for Space Suits in Orbit written by Kenneth R. Cramer and published by . This book was released on 1962 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cylindrical model of a space suit exposed to solar and metabolic heating is examined to determine the design criteria for minimizing equilibrium temperature differences. Resulting suit shell thicknesses are compared with those of a previous analysis that utilized the material thermal capacity and surface spectral properties to establish passive nonequilibrium temperature control. Results demonstrate that light-metal suits will develop small equilibrium temperature differences and be very heavy. Fabric suits of similar design will be even heavier. A water-filled suit shell is recommended as an attractive design approach if required circulation rates are practical. This is the second phase of an investigation to delineate the design parameters for controlling thermal environment in a space suit located in an orbit around the earth.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents fundamental theories, design and testing methodologies, and engineering applications concerning spacecraft thermal control systems, helping readers gain a comprehensive understanding of spacecraft thermal control systems and technologies. With abundant design methods, advanced technologies and typical applications to help them grasp the basic concepts and principles of engineering applications, it is mainly intended for engineering and technical staff engaged in spacecraft thermal control areas. The book discusses the thermal environments commonly used for space flight missions, rules and regulations for system design, thermal analysis and simulation, and thermal testing methods, as well as the design and validation of the thermal control systems for Chinese spacecraft, such as the Shenzhou spacecraft and Chang’e Lunar Lander and Rover. It also introduces them to communication and remote sensing satellites and presents advanced thermal control technologies developed in recent years, including heat transfer, heat insulation, heating, refrigeration and thermal sensor technologies. Addressing the design and validation of thermal control systems for various types of Chinese spacecraft, the book offers a valuable theoretical and practical reference guide for researchers and engineers alike.
