Aside from incidental, auxiliary loads, in level flight the principal load on the aircraft propulsion engine is the power required to provide the continuous lift. To construct an exergy flow diagram for an aircraft — for example, for the purpose of exergy costing — an expression is needed for the exergy delivered to (and by) the wings. That is, an expression is needed for the exergy of lift. In this paper an expression is developed for this quantity, applicable not only in level flight but indoi:10.1115/imece2001/aes-23644 fatcat:p3afwkjrabcybphj7a5smdttvu
