This book was released on 1903 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer assisted conceptual aircraft design program has been developed (CACAD). It has an optimisation capability, with extensive break-down in maintenance costs. CACAD's aim is to optimise the size, and configurations of turbofan-powered transport aircraft. A methodology was developed to enhance the reliability of current aircraft systems, and was applied to avionics systems. R & M models of thermal management were developed and linked with avionics failure rate and its maintenance cost prediction methods. The impact of the environmental control system, and engine-provided bleed flow was also modelled and incorporated into CACAD. The program showed the ARINC 600 & 408A flow rates to the avionics bay, and to the deck instruments may both profitably be increased by 50%. This keeps the direct operating cost (DOC) increase at bay for long-range passenger aircraft, and offers a reduction of up to 1% in DOC for the short to medium range passenger aircraft. A methodology was developed to model all aspects of future high risk technologies, with special consideration given to reliability, maintainability, and development cost (R, M & D) predictions as applied to variable camber wings (VCW). Many aspects of VCW were modelled. These included different types of drag saving due to chord- wise, as well as span-wise camber variation. Models were also derived for mass, maintenance cost, and extra development cost increments for wing trailing edge devices, flight control, and hydraulic systems. On incorporation into CACAD, a reduction in DOC of up to 3.5% was predicted. The VCW technology were evaluated for DOC improvements, against a number of existing, future, and derivative aircraft, under different sensitivity conditions. R, M & D predictions were shown to be decisive in addressing the feasibility of a new technology. The R & M predictions of the whole study shows that, long range, low to medium capacity derivative transport aircraft are most appropriate for the VCW technology, and.

Book excerpt: This book represents the proceedings of the 10th annual symposium of the Society of Reliability Engineers, Scandinavian Chapter, and was held in Stavanger, Norway, 9-11 October 1989. The theme of the symposium emphasised the need for obtaining a competitive edge through reliability in systems engineering and addressed the role of reliability in marketing, contracts, customer support and product liability. This book will be of interest to those involved in reliability engineering, risk assessment, safety and maintenance engineering.
Download or read book Introduction to Aircraft Design written by John P. Fielding and published by Cambridge University Press. This book was released on 2017-04-03 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of this popular textbook provides a modern, accessible introduction to the whole process of aircraft design from requirements to conceptual design, manufacture and in-service issues. Highly illustrated descriptions of the full spectrum of aircraft types, their aerodynamics, structures and systems, allow students to appreciate good and poor design and understand how to improve their own designs. Cost data is considerably updated, many new images have been added and new sections are included on the emerging fields of Uninhabited Aerial Vehicles and environmentally-friendly airlines. Examples from real aircraft projects are presented throughout, demonstrating to students the applications of the theory. Three appendices and a bibliography provide a wealth of information, much not published elsewhere, including simple aerodynamic formulae, an introduction to airworthiness and environmental requirements, aircraft, engine and equipment data, and a case study of the conceptual design of a large airliner.

This book was released on 2012-12-06 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliability data collection and its use in risk and availability assessment is a subject of increasing importance. The founders of EuReDatA, and in particular, Arne Ullman, the originator 'and first Chairman of the Association, recognised the need for a body capable of acting as a catalyst and providing a unified approach to this subject. It is therefore a prevailing objective of the European Reliability Databank Association to initiate and support contact between experts, companies and institutions active in reliability engineering and research. Although the first and principle interest of EuReDatA is reliability data and data banks, the Association is aware that these are tools that are used with others to establish and maintain reliability and safety. It is with this objective that EuReDatA regularly holds conferences and seminars covering a range of reliability topics. C.A. Campbell H.J.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a system reliability prediction method suitable for use during conceptual design, called the conceptual design reliability prediction method (CDRPM). The CDRPM extends the early design reliability prediction method (EDRPM) by facilitating parameter characterizations that follow non-normal distributions. Functional-physical reliability relationships are established through a hierarchical Bayesian model solved by Markov Chain Monte Carlo (MCMC) sampling and aggregated using the system's reliability block diagram (RBD) to assess the likelihood of candidate architectures meeting a reliability requirement. Reliability predictions based on different types of failure data, specifically success ratios and failure rates, are compared herein in a case study of a generic launcher system assessed by the CDRPM. This research shows the effects of failure data type selection and distribution assumptions on architecture down-selection, leading to enhanced insight during conceptual design analysis.
Download or read book Predicting Reliability and Maintainability Factors for Aircraft Subsystems During the Conceptual Phase of Aircraft Decision written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past thirty years, reliability and maintainability have become a growing part of system design. This is due in part to the knowledge imparted by the problems incurred on the first generation of complex jet aircraft. Many lessons were learned from the first generation aircraft that are now incorporated in modern aircraft design. Today's environment of budget cuts and constraints also requires reliability to be built into an aircraft design in the conceptual stage of design. For space systems, it is imperative that reliability be built into the design in the very early stages and considered throughout the design process. This case study used aircraft design and performance characteristics (independent variables) and reliability and maintainability parameters (dependent variables) in multiple regression analysis to develop parametric equations that predict reliability and maintainability factors for aircraft subsystems. The subsystems analyzed were landing gear and engines.

This book was released on 2017-03-19 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliability Based Aircraft Maintenance Optimization and Applications presents flexible and cost-effective maintenance schedules for aircraft structures, particular in composite airframes. By applying an intelligent rating system, and the back-propagation network (BPN) method and FTA technique, a new approach was created to assist users in determining inspection intervals for new aircraft structures, especially in composite structures. This book also discusses the influence of Structure Health Monitoring (SHM) on scheduled maintenance. An integrated logic diagram establishes how to incorporate SHM into the current MSG-3 structural analysis that is based on four maintenance scenarios with gradual increasing maturity levels of SHM. The inspection intervals and the repair thresholds are adjusted according to different combinations of SHM tasks and scheduled maintenance. This book provides a practical means for aircraft manufacturers and operators to consider the feasibility of SHM by examining labor work reduction, structural reliability variation, and maintenance cost savings. Presents the first resource available on airframe maintenance optimization Includes the most advanced methods and technologies of maintenance engineering analysis, including first application of composite structure maintenance engineering analysis integrated with SHM Provides the latest research results of composite structure maintenance and health monitoring systems
