Como sé muy poco de cuestiones técnicas, a veces cuando tengo tiempo trato de aggiornarme un poco-
Sospecho que muchos estarán en la misma situación.
Así que propongo poner aquí material de consulta para que el foro levante el nivel técnico; no es para recibirse de ingeniero aeronáutico, pero SUMA al conocimiento general del individuo y colectivo del Foro.
Link muy interesante sobre DISEÑO SOBRE AVIONES DE COMBATE: Imprescindible INGLES ó un buen diccionario-

DESIGN FOR AIR COMBAT
Swept wing or delta? Nose, ventral or wing-root intakes? One fin or two? Swing-wing or fixed geometry? These are some of the many decisions that have to be made by the designer of a modern combat aircraft. Though the paramount need for streamlining usually leads to shapes that are sleekly attractive, aesthetics don't come into it. Every line and surface in a fighter airframe has a precisely defined job to do. Design for Air Combat explains the rationale behind the aerodynamic design process, from the first outline of a requirement for a new type to the subtle interaction of the various structural components of the operational aircraft.
Along the way there will have been many compromises. The classical delta offers lower supersonic drag but demands excessive runway lengths. A wing design that gives good subsonic economy rapidly loses efficiency in the transonic region. Ventral intakes present the engine with orderly airflow at high angles of attack but can ingest damaging objects thrown up by the nosewheel. It is the designer's job to resolve these conflicts so that the Air Staff and its front-line squadrons get as much performance as possible for the money available and before existing equipment becomes incapable of meeting the threat.
Basic to any aircraft design are the principles of aerodynamics: how does a wing produce lift, what is drag and what causes it, how are lift and drag balanced to permit efficient flight? The Introduction sets out clearly the fundamentals of flight and introduces many of the concepts encountered in later chapters. Also explained are the requirements underlying combat aircraft, starting with the emergence of a new threat and leading from project definition, via preliminary design, to full-scale design and development.
Subsequent chapters cover in turn the major components of an airframe: wing, air intakes, fuselage, tailplane, fin, and aft-body/exhaust. The major attributes and variations of each are examined in detail, and the design issues illustrated by reference to actual development work. In the case of the wing, for instance, the parameters include aerofoil section, camber and twist, aspect ratio, wingtip shape and taper ratio, while the principal variations on the basic straight surface are the aft-swept, delta and forward-swept wings. Case histories illuminating the ebb and flow of influences at work on the designer include the story of the Dassault Mirage family, which has gone with equal success from classical delta to swept wing and back again as requirements and technologies have advanced.
Although each major component is isolated for the purposes of analysis, its interaction with the rest of the airframe is not neglected. The designer must be alive to both the negative effects of tailplane wake on fin effectiveness at high angles of attack, and the desirable consequences of strake-induced vortices for mainplane lift. In fact the day of the totally integrated airframe has already dawned, in the form of the control-configured vehicle. Made possible by recent advances in high-power, high-reliability microcomputing, such aircraft are deliberately endowed with reduced stability, resulting in large weight savings and manoeuvrability improvements. One of the most significant developments of the last decade, this technique, known as "relaxed static stability". (RSS), is discussed at length.
Illustrated with more than 230 clear, uncluttered line drawings and 50 photographs, Design for Air Combat takes an increasingly complex aspect of aerospace technology and makes it readily understandable to the first-year student, industry and service professionals, and anyone who wants to understand the fascinating interplay of forces that sculpts the modern combat aircraft.
