Competitive Assessment of the U.S. Large Civil Aircraft Aerostructures Industry


Book Description

"This study was requested by the House Committee on Ways and Means in a letter dated March 8, 2000. The Committee requested that the U.S. International Trade Commission (the Commission) examine the ability of the U.S. civil aerostructures industry to compete over the short and long terms with those industries in Europe, Canada, and to the extent possible, Asia. The Commission's report examines the composition and recent trends of the large civil aircraft (LCA) aerostructures industry; the process of new aerostructures development; the means and trends of government support for research and development; and the relative strengths and weaknesses of the aerostructures industries in these countries and regions, for the period 1995-99 and to the extent possible, 2000"--Publisher description

Change, Transformation and Development


Book Description

For as long as one can remember, the edifice of the neoclassical economic syn thesis has been under attack. Critiques have focused on the extreme unreality of the assumptions that underpin the Arrow-Debreu theorems of welfare economics. They have queried the excessive formalism of the edifice, and the lack of practical significance of many of the results.They have castigated the neoclassical synthesis for its internal incoherence (lacking an independent theory of capital, for example, one of the favorite topics of the Cambridge school), its lack of a dynamic element, its non-evolutionary character, its lack of any conception of "market process" and so the list could be continued (Blaug, 1997). Through all this, the neoclassi cal synthesis remains as strong as ever, impervious it seems to these or any other attacks. In this paper a different tack is taken. The neoclassical edifice is left alone, standing as a representation of what goes on in a certain kind ofeconomy- namely the economy wheregoods and services are producedand exchanged. The paper then introduces another kind of economy, namely an economy of productive entities called "resources"- that are needed to produce the economyofgoods and services.




Performance of the Jet Transport Airplane


Book Description

Performance of the Jet Transport Airplane: Analysis Methods, Flight Operations, and Regulations presents a detailed and comprehensive treatment of performance analysis techniques for jet transport airplanes. Uniquely, the book describes key operational and regulatory procedures and constraints that directly impact the performance of commercial airliners. Topics include: rigid body dynamics; aerodynamic fundamentals; atmospheric models (including standard and non-standard atmospheres); height scales and altimetry; distance and speed measurement; lift and drag and associated mathematical models; jet engine performance (including thrust and specific fuel consumption models); takeoff and landing performance (with airfield and operational constraints); takeoff climb and obstacle clearance; level, climbing and descending flight (including accelerated climb/descent); cruise and range (including solutions by numerical integration); payload–range; endurance and holding; maneuvering flight (including turning and pitching maneuvers); total energy concepts; trip fuel planning and estimation (including regulatory fuel reserves); en route operations and limitations (e.g. climb-speed schedules, cruise ceiling, ETOPS); cost considerations (e.g. cost index, energy cost, fuel tankering); weight, balance and trim; flight envelopes and limitations (including stall and buffet onset speeds, V–n diagrams); environmental considerations (viz. noise and emissions); aircraft systems and airplane performance (e.g. cabin pressurization, de-/anti icing, and fuel); and performance-related regulatory requirements of the FAA (Federal Aviation Administration) and EASA (European Aviation Safety Agency). Key features: Describes methods for the analysis of the performance of jet transport airplanes during all phases of flight Presents both analytical (closed form) methods and numerical approaches Describes key FAA and EASA regulations that impact airplane performance Presents equations and examples in both SI (Système International) and USC (United States Customary) units Considers the influence of operational procedures and their impact on airplane performance Performance of the Jet Transport Airplane: Analysis Methods, Flight Operations, and Regulations provides a comprehensive treatment of the performance of modern jet transport airplanes in an operational context. It is a must-have reference for aerospace engineering students, applied researchers conducting performance-related studies, and flight operations engineers.
