Available in PDF, EPUB and Kindle. Book excerpt: Planning Research Corporation, has conducted a series of studies to develop techniques for estimating the cost of fixed-wing aircraft. The primary objective of these studies is to develop techniques suitable for use in program planning, cost-effectiveness studies, and evaluation of contractor proposals. A further objective is to provide insight into problems of cost analysis and to suggest an analytical methodology for developing estimating relationships that will be useful to analysts in the military departments in preparing estimates of cost for new weapons system programs.

This book was released on 2007-07-30 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the important national defense contribution of large, non-fighter aircraft, rapidly increasing fuel costs and increasing dependence on imported oil have triggered significant interest in increased aircraft engine efficiency by the U.S. Air Force. To help address this need, the Air Force asked the National Research Council (NRC) to examine and assess technical options for improving engine efficiency of all large non-fighter aircraft under Air Force command. This report presents a review of current Air Force fuel consumption patterns; an analysis of previous programs designed to replace aircraft engines; an examination of proposed engine modifications; an assessment of the potential impact of alternative fuels and engine science and technology programs, and an analysis of costs and funding requirements.

Download or read book Weapon System Costing Methodology for Aircraft Airframes and Basic Structures Volume I Technical Volume written by R. E. Kenyon and published by . This book was released on 1975 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a detailed description of the function and use of two weapon system costing methodologies for aircraft airframes and basic structures developed for the Air Force Flight Dynamics Laboratory for use in conceptual and preliminary designs phases of weapon system development. The methods are a trade study costing method for detailed cost analysis of trades-off between weight, cost, type of construction and type of material and a system costing method for determining the projected cost of a complete airframe within the context of a weapon system development. This volume provides a technical discussion of method development. Tradeoff capability has been provided for a range of alternative structure and material combinations. A technique for independently assessing complexity factors has been developed and demonstrated. Manufacturing costs are separately estimated for the primary elements of substructure: ribs, spars, covers, leading edges, trailing edges, tips, etc. The trade study method provides an iterative capability stemming from a direct interface with design synthesis programs. A detailed cost data base and system for data expansion is provided. The methods are designed for ease in changing cost estimating relationships and estimating coefficients resulting from cost data update. (Author).

This book was released on 1973 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the interim results of a study aimed at extending cost estimating techniques developed and demonstrated under a previous contract. The previous study resulted in two separate estimating methods: a trade study and a system costing method. These methods provided two essential estimating capabilities: the capability of assessing the relative difference in the cost of the basic structures attributable to variations in type of construction and material in an iterative fashion to support tradeoff studies during the preliminary design process, and the capability of accurately estimating total airframe costs in manhours and materials for selected design while retaining sensitivity to type of material and construction.

Download or read book Cost Estimating Relationships for Fixed Wing Aircraft written by William Joel Ditto and published by . This book was released on 1985 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Cost Estimating Relationship (CER) for Fixed Wing Aircraft was developed to estimate the unit cost of a twin engine, commercial, turbo-prop aircraft procured off the shelf. The Army has a limited fixed wing capability and most of this capability is procured in a commercial environment instead of through a typical rotor wing procurement cycle. The list price in the commercial market includes both engines and standard avionics, while in a typical Government rotor wing procurement these items are Government Furnished Equipment. Therefore, this CER was developed using the parameter of empty weight and aircraft commercial list price. The data collected was analyzed using the Statistical Analysis System (SAS) on the AVSCOM Scientific and Engineering Computer System. The program developed is a linear regression of the form (y = a + bx), and the results are shown in the report.

Available in PDF, EPUB and Kindle. Book excerpt: The study examines the first unit labor cost parameter of the learning curve equations belonging to seven different aircraft. The purpose of this investigation is to find a method which will produce good estimates of this parameter prior to the start of production of an aircraft. Simple linear, and log linear, multtiple variable relations were tested for accurate estimates against non-linear functions of weight and time. (Author).
Download or read book Life Cycle Costing written by B. Dhillon and published by Routledge. This book was released on 1989-09-11 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Product acquisition involves an examination of the support cost of major equipment over its total life years. Depending on the type of equipment, support costs may range from 10 to 100 times the cost of acquisition. 'Life Cycle Costing: Techniques, Models and Applications' offers a comprehensive approach to the entire field, and treats it in such a way that the reader requires no previous knowledge to understand the contents. It covers all advances and recent progress in life cycle costing from its history and definitions to current approaches. It is fully referenced for deeper study in any specific area (there are over 1150 references with an appendix) and contains more than 50 examples with their solutions. Subjects covered include reliability improvement warranty, computer hardware and software costing, vehicles life cycle costing, reliability engineering, life cycle costing in the aircraft industry, and processing systems costing. This work is intended for all engineers and senior students of engineering or business administration, administrators, cost analysts, researchers, academics, and anyone involved with equipment procurement.

Download or read book A Method for Estimating the Cost of Aircraft Structural Modification written by J. L. Birkler and published by RAND Corporation. This book was released on 1981-01-01 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes research into the cost of aircraft structural modifications. Detailed cost and man hour data supplied by the airframe industry permitted derivation of estimating tools for major aircraft components. Separate equations were derived for engineering, tooling, manufacturing, and material cost. The major explanatory variable was always weight. It was hypothesized that structural modification cost could be estimated on the basis of the weight of material added. Estimates of the cost of modification for the B-52, C-141, C-5, and EF-111 were compared with cost data from industry. Considerable informed judgment is required as is a knowledge of such program-specific facts as whether the original production tooling still exists. Rather than a mathematical model, the study describes the kinds of information needed, suggests guidelines, and presents estimating equations for airframe systems and subassemblies. These contribute to an understanding of the estimating problem but do not constitute a general solution. (Author).
