Nomenclature b= wing span c = aircraft reference chord = aircraft local chord dc = aircraft drag counts, based on aircraft reference area CD = drag coefficient based on aircraft reference areaof a nacelle M = Mach number V = Velocity x,y,z = Cartesian coordinate system for the aircraft ξ, η, ζ = Cartesian coordinate system for the engine ξ, R, Θ = Cylindrical coordinate system for the engine = force in the drag domain = force in the thrust domain Acronyms AoA = Angle of Attack = Effective angle of attack for an engine / = Angle of attack for an aircraft axis = Geometrical angle of engine installation CRM = NASA Common Research Model GPF = Gross Propulsive Force MFCR = mass flow capture ratio NPF = Net Propulsive Force NPR = Nozzle Pressure Ratio TET = Turbine Entry Temperature TFN = Through Flow Nacelle WB = Wing Body WBNP = Wing Body with Nacelle and Pylon WBT0 = Wing Body with 0° inclined Tailplane
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
