The most comprehensive, current guide to aircraft powerplantsFully revised to cover the latest industry advances, Aircraft Powerplants, Eighth Edition, prepares you for certification as an FAA powerplant technician in accordance with the Federal Aviation Regulations (FAR). This authoritative text has been updated to reflectrecent changes in FAR Part 147.This new edition features expanded coverage of turbine-engine theory and nomenclature; current models of turbofan, turboprop, and turboshaft engines; and up-to-date details on turbine-engine fuel, oil, and ignition systems. Important information on how individualcomponents and systems operate together is integrated throughout the text. Clear photos of various components and a full-color insert of diagrams and systems are included. Review questions at the end of each chapter enable you to check your knowledge of the topics presented in this practical resource.Aircraft Powerplants, Eighth Edition, covers:Aircraft powerplant classification and progressReciprocating-engine construction and nomenclatureInternal-combustion engine theory and performanceLubricants and lubricating systemsInduction systems, superchargers, turbochargers, and cooling and exhaust systemsBasic fuel systems and carburetorsFuel injection systemsReciprocating-engine ignition and starting systemsOperation, inspection, maintenance, and troubleshooting of reciprocating enginesReciprocating-engine overhaul practicesGas-turbine engine: theory, jet propulsion principles, engine performance, and efficienciesPrincipal parts of a gas-turbine engine, construction, and nomenclatureGas-turbine engine: fuels and fuel systemsTurbine-engine lubricants and lubricating systemsIgnition and starting systems of gas-turbine enginesTurbofan, turboprop, and turboshaft enginesGas-turbine operation, inspection, troubleshooting, maintenance, and overhaulPropeller theory, nomenclature, and operationTurbopropellers and control systemsPropeller installation, inspection, and maintenanceEngine indicating, warning, and control systems
This econometric study covers the world outlook for rocker arms and parts for internal combustion engines excluding aircraft and gasoline automotive engines and gas turbines across more than 200 countries. For each year reported, estimates are given for the latent demand, or potential industry earnings (P.I.E.), for the country in question (in millions of U.S. dollars), the percent share the country is of the region and of the globe. These comparative benchmarks allow the reader to quickly gauge a country vis-a-vis others. Using econometric models which project fundamental economic dynamics within each country and across countries, latent demand estimates are created. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study also does not consider short-term cyclicalities that might affect realized sales. The study, therefore, is strategic in nature, taking an aggregate and long-run view, irrespective of the players or products involved. This study does not report actual sales data (which are simply unavailable, in a comparable or consistent manner in virtually all of the 230 countries of the world). This study gives, however, my estimates for the worldwide latent demand, or the P.I.E., for rocker arms and parts for internal combustion engines excluding aircraft and gasoline automotive engines and gas turbines. It also shows how the P.I.E. is divided across the world's regional and national markets. For each country, I also show my estimates of how the P.I.E. grows over time (positive or negative growth). In order to make these estimates, a multi-stage methodology was employed that is often taught in courses on international strategic planning at graduate schools of business.
This report was created for global strategic planners who cannot be content with traditional methods of segmenting world markets. With the advent of a "borderless world", cities become a more important criteria in prioritizing markets, as opposed to regions, continents, or countries. This report covers the top 2000 cities in over 200 countries. It does so by reporting the estimated market size (in terms of latent demand) for each major city of the world. It then ranks these cities and reports them in terms of their size as a percent of the country where they are located, their geographic region (e.g. Africa, Asia, Europe, Middle East, North America, Latin America), and the total world market. In performing various economic analyses for its clients, I have been occasionally asked to investigate the market potential for various products and services across cities. The purpose of the studies is to understand the density of demand within a country and the extent to which a city might be used as a point of distribution within its region. From an economic perspective, however, a city does not represent a population within rigid geographical boundaries. To an economist or strategic planner, a city represents an area of dominant influence over markets in adjacent areas. This influence varies from one industry to another, but also from one period of time to another. In what follows, I summarize the economic potential for the world's major cities for "rocker arms and parts for internal combustion engines excluding aircraft and gasoline automotive engines and gas turbines" for the year 2009. The goal of this report is to report my findings on the real economic potential, or what an economist calls the latent demand, represented by a city when defined as an area of dominant influence. The reader needs to realize that latent demand may or may not represent real sales.
