The new edition of this classic international textbook, used by universities, training schools, industry and enthusiasts, has been extended to feature a number of new studies in practical aeroplane design. Mathematics - Which general readers may skip, is the minimum needed to work out common-sense shapes, aimed at meeting the certification requirements of the three world airworthiness authorities: FAA (USA), British CAA and European JAA. Land and seaplanes are included, from micro light and commuter, to a 30 seat surface effect (ekranoplan) regional transport, to satisfy specific markets. A new chapter, on 'Using the back of an envelope', shows how to make 'ballpark' technical judgments.Table of Contents:Section 1 - Introduction: Airworthiness the objectVocabulary of DesignSection 2 - Aerodynamics: The nature of airArrangement of surfacesDrag, flaps and wakesSection 3 - Performance: Power for flightReciprocating enginesTurbine engines and a range equationSection 4 - Operational Characteristics: Fuselages, hulls and floatsChoice of landing gearLongitudinal stabilityControl surfacesLateral and directional stability and spinningHow big and how heavySection 5 - Project Examples: Layout, including 'Using the back of an envelope
