Turbprop or turbojet engines are the main means of providing motive power for flight. Any improvements which can be made to these technologies in terms of power or fuel efficiency are significant and important developments. After first setting the scene with a short account of aeroengine development, the book goes on to show how a super-turbocharged aeroengine can be significantly more efficient. A detailed account of the studies into the new design philosophy is given and the numerical results of the computational model of this engine design model are analysed. The unusual design of these piston engine units is theoretically modelled and their mechanical design is discussed in some detail. CONTENTS: Conventional jet engine perfomance Centrifugal supercharger Emissions Performance at altitude Axial piston engine Gas generator Turbine and high-speed alternator design Optimisation techniques Numerical modelling and results Compound turbocharged engineTo carry out this validation procedure a second validation program is employed. ... To do this, data for three very different engines is used : a Suzuki naturally aspirated motorcycle engine (11), a Lotus ... Apart from the Lotus engine, where ignition timing could be estimated from a pressure-crank angle diagram, ignition anbsp;...
