Book Description
The Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center has been developing robotic equipment and machinery for highway maintenance and construction operations. It is a cooperative venture between the University of California at Davis and the California Department of Transportation (Caltrans). The research and development projects have the goal of increasing safety and efficiency of roadwork operations through the appropriate application of automation solutions. This report describes the continuing development of automated equipment for deploying and retrieving traffic cones. In this latest phase of the project, the center has continued the development of the automated cone machine (ACM) through further testing and development of the first generation integrated prototype ACM and the design and fabrication of an integrated Multi-stack ACM developed to maximize the number of cones carried by the automated cone machine. Included in this report is the development of an improved control system for the retrieval arm which is a critical component used to pick up the traffic cone off the road. A first generation ACM prototype (ACM 1) is being used in tests and demonstrations on the highways of California. Operators using ACM 1 can place and retrieve cones without any set up and control the machine from within the confines of the cab. These machines can easily be run by a single operator and are very compatible with the process of closing a lane. The ACM 1 design was integrated into the existing Caltrans manual cone body truck and was limited to two stacks of 40 cones each. The new ACM multistack is designed to carry six stacks of 50 cones for a total of 300 cones. These machines are unambiguous demonstrations of the successful application of automation in a very demanding environment. This development work and the continued support of commercialization at AHMCT support the Caltrans goal of making these machines available to the maintenance operations.

Columbia Crew Survival Investigation Report

Book Description
NASA commissioned the Columbia Accident Investigation Board (CAIB) to conduct a thorough review of both the technical and the organizational causes of the loss of the Space Shuttle Columbia and her crew on February 1, 2003. The accident investigation that followed determined that a large piece of insulating foam from Columbia's external tank (ET) had come off during ascent and struck the leading edge of the left wing, causing critical damage. The damage was undetected during the mission. The Columbia accident was not survivable. After the Columbia Accident Investigation Board (CAIB) investigation regarding the cause of the accident was completed, further consideration produced the question of whether there were lessons to be learned about how to improve crew survival in the future. This investigation was performed with the belief that a comprehensive, respectful investigation could provide knowledge that can protect future crews in the worldwide community of human space flight. Additionally, in the course of the investigation, several areas of research were identified that could improve our understanding of both nominal space flight and future spacecraft accidents. This report is the first comprehensive, publicly available accident investigation report addressing crew survival for a human spacecraft mishap, and it provides key information for future crew survival investigations. The results of this investigation are intended to add meaning to the sacrifice of the crew's lives by making space flight safer for all future generations.

Parachute Recovery Systems
Author: Theo W. KnackePublisher:
ISBN:
Category : Sports & Recreation
Languages : en
Pages : 524
Book Description
The purpose of this manual is to provide recovery system engineers in government and industry with tools to evaluate, analyze, select, and design parachute recovery systems. These systems range from simple, one-parachute assemblies to multiple-parachute systems, and may include equipment for impact attenuation, flotation, location, retrieval, and disposition. All system aspects are discussed, including the need for parachute recovery, the selection of the most suitable recovery system concept, concept analysis, parachute performance, force and stress analysis, material selection, parachute assembly and component design, and manufacturing. Experienced recovery system engineers will find this publication useful as a technical reference book; recent college graduates will find it useful as a textbook for learning about parachutes and parachute recovery systems; and technicians with extensive practical experience will find it useful as an engineering textbook that includes a chapter on parachute- related aerodynamics. In this manual, emphasis is placed on aiding government employees in evaluating and supervising the design and application of parachute systems. The parachute recovery system uses aerodynamic drag to decelerate people and equipment moving in air from a higher velocity to a lower velocity and to a safe landing. This lower velocity is known as rate of descent, landing velocity, or impact velocity, and is determined by the following requirements: (1) landing personnel uninjured and ready for action, (2) landing equipment and air vehicles undamaged and ready for use or refurbishment, and (3) impacting ordnance at a preselected angle and velocity.

Book Description
The GOES-R Series: A New Generation of Geostationary Environmental Satellites introduces the reader to the most significant advance in weather technology in a generation. The world's new constellation of geostationary operational environmental satellites (GOES) are in the midst of a drastic revolution with their greatly improved capabilities that provide orders of magnitude improvements in spatial, temporal and spectral resolution. Never before have routine observations been possible over such a wide area. Imagine satellite images over the full disk every 10 or 15 minutes and monitoring of severe storms, cyclones, fires and volcanic eruptions on the scale of minutes. - Introduces the GOES-R Series, with chapters on each of its new products - Provides an overview of how to read new satellite images - Includes full-color images and online animations that demonstrate the power of this new technology
