Available in PDF, EPUB and Kindle. Book excerpt: A prototype on-board oxygen generation system (OBOGS) is being tested by the USAF School of Aerospace Medicine (SAM). The OBOGS is a candidate to replace present liquid oxygen systems for aircrew consumption on manned aircraft. The OBOGS passes outside air through a molecular sieve to produce an oxygen enriched breathing product. Oxygen concentration of the OBOGS's output is controlled by a purge orifice valve. The SAM envisions using a digital system to control the OBOGS. A digital control system for the OBOGS was developed and consists of a stepper motor, microprocessor, system sensor, support circuitry, and software. The control system software is a collection of instructions which allow the MPU to read data from sensors, to interpret that data, and to issue system hardware control signals. System software was fairly complex as methods were employed to compensate for the OBOGS's lengthy response time. This was accomplished by using a segmented table. If motor drive is anticipated to be time-consuming, a software routine is used to preposition the motor to a predetermined location within the segmented table. This position is updated when more accurate information is available. A prototype system was constructed and tested in the laboratory. The control system successfully controlled the stepper motor.

Available in PDF, EPUB and Kindle. Book excerpt: As the Department of Defense continues development of the future warrior system, the difficulty of moving rapidly from design to manufacturing for complex technologies is becoming a major concern. In particular, there are communication gaps between design and manufacturing that hinder rapid development of new products important for these future military developments. To help address those concerns, DOD asked the NRC to develop a framework for "bridging" these gaps through data management, modeling, and simulation. This report presents the results of this study. It provides a framework for virtual design and manufacturing and an assessment of the necessary tools; an analysis of the economic dimensions; an examination of barriers to virtual design and manufacturing in the DOD acquisition process; and a series of recommendations and research needs.

Download or read book Introduction to Modeling and Control of Internal Combustion Engine Systems written by Lino Guzzella and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internal combustion engines still have a potential for substantial improvements, particularly with regard to fuel efficiency and environmental compatibility. These goals can be achieved with help of control systems. Modeling and Control of Internal Combustion Engines (ICE) addresses these issues by offering an introduction to cost-effective model-based control system design for ICE. The primary emphasis is put on the ICE and its auxiliary devices. Mathematical models for these processes are developed in the text and selected feedforward and feedback control problems are discussed. The appendix contains a summary of the most important controller analysis and design methods, and a case study that analyzes a simplified idle-speed control problem. The book is written for students interested in the design of classical and novel ICE control systems.

This book was released on 2018-06-15 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this technology assessment is to define a multiphase research study program investigating Onboard Inert Gas Generation Systems (OBIGGS) and Onboard Oxygen Generation Systems (OBOGS) that would identify current airplane systems design and certification requirements (Subtask 1); explore state-of-the-art technology (Subtask 2); develop systems specifications (Subtask 3); and develop an initial system design (Subtask 4). If feasible, consideration may be given to the development of a prototype laboratory test system that could potentially be used in commercial transport aircraft (Subtask 5). These systems should be capable of providing inert nitrogen gas for improved fire cargo compartment fire suppression and fuel tank inerting and emergency oxygen for crew and passenger use. Subtask I of this research study, presented herein, defines current production aircraft certification requirements and design objectives necessary to meet mandatory FAA certification requirements and Boeing design and performance specifications. These requirements will be utilized for baseline comparisons for subsequent OBIGGS/OBOGS application evaluations and assessments.
