21 complexity design essay space suit technology
On July 12, , only 21 layers of fabric, most gossamer-thin, stood between Neil Armstrong and Buzz Aldrin and the lethal desolation of a lunar vacuum. The story of the Apollo spacesuit is the surprising tale of an unexpected victory: that of Playtex, maker of bras and girdles, over the large military-industrial contractors better positioned to secure the spacesuit contract. One of the most fascinating aspects of the spacesuits is its testament to combinatorial creativity and the idea that everything comes from what came before. Monchaux writes:. A space suit is made out of a flight suit, a Goodrich tire, a bra, a girdle, a raincoat, a tomato worm.

Space Shuttle missions. It is thus desirable to determine and analyze, and possibly foresee, as accurately as possible what radiation exposures crew members involved in EVAs will experience in order to minimize risks and to establish exposure limits that must not to be exceeded. A detailed CAD model of the U. The doses within the CAM and CAF models are determined from energy deposition at given target points along directional rays convergent on the points and are evaluated for several points on the skin and within the body.
Dosimetric quantities include contributions from primary protons, light ions, and electrons, as well as from secondary brehmsstrahlung and target fragments. Directional dose patterns are displayed as rays and on spherical surfaces by the use of a color relative intensity representation.
Wilson, J. A detailed spacesuit computational model is being developed at the Langley Research Center for radiation exposure evaluation studies. The details of the construction of the spacesuit are critical to estimation of exposures and assessing the risk to the astronaut on EVA. Past evaluations of spacesuit shielding properties assumed the basic fabric lay-up Thermal Micrometeroid Garment, fabric restraints, and pressure envelope and Liquid Cooling and Ventilation Garment LCVG could be homogenized as a single layer overestimating the protective properties over 60 percent of the fabric area.
The present spacesuit model represents the inhomogeneous distributions of LCVG materials mainly the water filled cooling tubes. An experimental test is performed using a MeV proton beam and highresolution detectors to compare with model -predicted transmission factors. Some suggestions are made on possible improved construction methods to improve the spacesuit 's protection properties.
NASA has continued the development of space systems by applying and integrating improved technologies that include safety issues, lightweight materials, and electronics. In this paper the Mark III spacesuit is discussed in detail that includes the various components that comprise the spacesuit , materials and their chemical composition that make up the spacesuit , and a discussion of the 3-D CAD model of the Mark III spacesuit.
We combined the spacesuit and the human models , that is, we developed a method of incorporating the human models in the Mark III spacesuit and performed a ray-tracing technique to determine the space radiation shielding distributions for all of the critical body organs.
These body organ shielding distributions include the BFO Blood-Forming Organs , skin, eye, lungs, stomach, and colon, to name a few, for both the male and female. Using models of the trapped Van Allen proton and electron environments, radiation exposures were computed for a typical low earth orbit LEO EVA mission scenario including the geostationary GEO high electron environment. A radiation exposure assessment of these mission scenarios is made to determine whether or not the crew radiation exposure limits are satisfied, and if not, the additional shielding material that would be required to satisfy the crew limits.

This guidebook explains in depth the elements depicted on the wall chart in see-through and cut-away perspectives. Together the wall chart and guidebook show as well as explain the inside workings of the spacesuit and its various components.
Forty separate elements are identified with an accompanying numerical legend. Those elements are further explained in this guidebook along with their functions and how they work in relation to other elements. Additional chapters discuss essential components of the spacesuit such as the primary life support system and the manned maneuvering unit, and the method for donning the spacesuit. S March Spacesuit inner gloves consist of pressure bladders covered by Beta Cloth.
The thumb and fingertips of the glove are molded of silicone rubber to permit a degree of sensitivity. The inner gloves attach to the suit by pressure sealing rings, similar to these used in helmet-to-suit connections. The outer gloves served as a cover to protect from micrometeorites, abrasions and heat. Chinese Spacesuit Analysis.
An overview of the Chinese spacesuit and life support system were assessed from video downlinks during their EVA; from those assessments, spacesuit characteristics were identified. The spacesuits were compared against the Russian Orlan Spacesuit and the U. China's plans for future missions also were presented.

Contains 11 references. The flow. The incorporation of existing CAD geometry, the powerful use of a pre and post processor and the ability to do interdisciplinary analysis, will be described. US Spacesuit Knowledge Capture. The ability to learn from both the mistakes and successes of the past is vital to assuring success in the future. Due to the close physical interaction between spacesuit systems and human beings as users, spacesuit technology and usage lends itself rather uniquely to the benefits realized from the skillful organization of historical information; its dissemination; the collection and identification of artifacts; and the education of those in the field.
Spacesuit Knowledge Capture since the beginning of space exploration. Avenues used to capture the knowledge have included publication of reports; conference presentations; specialized seminars; and classes usually given by veterans in the field. More recently the effort has been more concentrated and formalized whereby a new avenue of spacesuit knowledge capture has been added to the archives in which videotaping occurs engaging both current and retired specialists in the field presenting technical scope specifically for education and preservation of knowledge.
With video archiving, all these avenues of learning can now be brought to life with the real experts presenting their wealth of knowledge on screen for future learners to enjoy. Scope and topics of U. Concurrently, U.
CAD-model -based vision for space applications. A pose acquisition system operating in space must be able to perform well in a variety of different applications including automated guidance and inspections tasks with many different, but known objects. Since the space station is being designed with automation in mind, there will be CAD models of all the objects, including the station itself.
The construction of vision models and procedures directly from the CAD models is the goal of this project. We address the reconstruction of 3D CAD models from point cloud data acquired in industrial environments, using a pre-existing 3D model as an initial estimate of the scene to be processed.
Indeed, this prior knowledge can be used to drive the reconstruction so as to generate an accurate 3D model matching the point cloud. We more particularly focus our work on the cylindrical parts of the 3D models. We propose to state the problem in a probabilistic framework: we have to search for the 3D model which maximizes some probability taking several constraints into account, such as the relevancy with respect to the point cloud and the a priori 3D model , and the consistency of the reconstructed model.
The resulting optimization problem can then be handled using a stochastic exploration of the solution space, based on the random insertion of elements in the configuration under construction, coupled with a greedy management of the conflicts which efficiently improves the configuration at each step. We show that this approach provides reliable reconstructed 3D models by presenting some results on industrial data sets.
Spacesuit glove manufacturing enhancements through the use of advanced technologies. The sucess of astronauts performing extravehicular activity EVA on orbit is highly dependent upon the performance of their spacesuit gloves. A study has recently been conducted to advance the development and manufacture of spacesuit gloves. The process replaces the manual techniques of spacesuit glove manufacture by utilizing emerging technologies such as laser scanning, Computer Aided Design CAD , computer generated two-dimensional patterns from three-dimensionl surfaces, rapid prototyping technology, and laser cutting of materials, to manufacture the new gloves.
Results of the program indicate that the baseline process will not increase the cost of the gloves as compared to the existing styles, and in production, may reduce the cost of the gloves. Greater accuracy was achieved in the baseline anthropometric measurement and CAD data measurement which subsequently improved the design feature. This effectively enhances glove performance through better fit and comfort.

Defect modelling in an interactive 3-D CAD environment. This extension of the Workbeach now provides the user with a well established modelling approach, coupled with a graphical user interface for: a configuring the model for flaw size, shape, orientation and location; b flexible specification of probe parameters; c selection of scanning surface and scan pattern on the CAD component model ; d presentation of the output as a simulated ultrasound image within the component, or as graphical or tabular displays.
The defect modelling facilities of the Workbench can be used for inspection procedure assessment and confirmation of data interpretation, by comparison of overlay images generated from real and simulated data. The modelling technique currently implemented is based on the Geometrical Theory of Diffraction, for simulation of strip-like, circular or elliptical crack responses in the time harmonic or time dependent cases. Eventually, the Workbench will also allow modelling using elastodynamic Kirchhoff theory.

In German more than 17 billions of Mark are moved to other industries, because clothes do not fit. Individual clothing tailored to the customer's preference means surplus value, pleasure and perfect fit. The body scanning technology is the key to generation and use of human 3D- CAD models for both, the ergonomic design of working environments and made to measure garment production. Ham in Spacesuit. Ham, a three-year-old chimpanzee, in the spacesuit he would wear for the second Mercury- Redstone MR-2 suborbital test flight in January, The Mercury capsule rode atop a modified Redstone rocket, developed by Dr.
Geant4 is a widely used Monte Carlo transport simulation package. However, it is time-consuming and error-prone to manually describe the models by GDML.
Automatic modeling methods have been developed recently, but there are some problem existed in most of present modeling programs, specially some of them were not accurate or adapted to specifically CAD format. At first, CAD model was decomposed to several simple solids which had only one close shell. And then the simple solid was decomposed to convex shell set.
Then corresponding GDML convex basic solids were generated by the boundary surfaces getting from the topological characteristic of a convex shell. After the generation of these solids, GDML model was accomplished with series boolean operations. The results showed that this method could convert standard CAD model accurately, and can be used for Geant4 automatic modeling. Stewart, John E. Scott; Samareh, Jamshid A. This software automates the mechanical development of a product from its conceptual design through manufacturing.
Few surgical products are designed in conjunction with accurate CAD models of human anatomy because of the difficulty with which these models are created. We have developed a novel technique that creates anatomically accurate, patient specific CAD solids from medical images in a matter of minutes.

Space Suit : 21 Essays on Technology, Complexity and Design
When Neil Armstrong and Buzz Aldrin stepped onto the lunar surface in July of , they wore spacesuits made by Playtex: 21 layers of fabric, each with a distinct yet interrelated function, custom-sewn for them by seamstresses whose usual work was fashioning bras and girdles. This book is the story of that spacesuit. Playtex's spacesuit went up against hard armor-like spacesuits designed by military contractors and favored by NASA's engineers. In Spacesuit , Nicholas de Monchaux tells the story of the layer spacesuit in 21 chapters addressing 21 topics relevant to the suit, the body, and the technology of the 20th century. The layer spacesuit, de Monchaux argues, offers an object lesson.

It is, arguably, one of the most famous photographs of the Space Age: Buzz Aldrin standing on the surface of the Moon, a human figure on an alien world. Yet, while much has been written about that mission to the Moon, including the rockets and spacecraft that made it possible and the men who made the journey, far less has been written about the spacesuit that allowed Armstrong and Aldrin to venture outside their spacecraft. An assistant professor of architecture at the University of California Berkeley, de Monchaux takes as inspiration for his book the A7L spacesuit worn on that historic moonwalk. The suit was a complex arrangement of 21 layers of material 28 layers in suits used later in the Apollo program strong enough to protect the wearer from the harsh environment of space yet light and flexible enough to allow him to move around. ILC had a small government division that by the s worked on pressure suits and, later, bid on the Apollo space suit. The book portrays ILC as struggling just as much, if not more, with corporate and government bureaucracy as it did designing and making the suits. ILC, though, demonstrated that their processes worked, proving it in sometimes unorthodox ways: to illustrate the performance of the modified layer suit, the company made a film of a test subject wearing the suit playing football on a local high school field. Soon after, NASA accepted the suit. Spacesuit , though, is not a detailed technical history of the development of the A7L spacesuit, and de Monchaux does not go through the spacesuit layer by layer. Some discuss the early history of high-altitude flight and the development of pressure suits, another examines Soviet approaches to spacesuit design. Some, which tackle topics as diverse as John F. Towards the end of the book, de Monchaux asks a simple but profound question: why is the spacesuit soft? While ILC and others developed spacesuit concepts based on latex and other flexible materials, other companies studied rigid suit concepts. Jeff Foust jeff thespacereview.
