BOYD, J.R., ENERGY-MANEUVERABILITY THEORY (VOL.1), et al (15-JAN-1965)., This report shows how an aircraft's energy state and energy rate capabilities are directly related to operational maneuverability and efficiency in terms of energy-maneuverability theory. It demonstrates also how energy-maneuverability theory may be applied to assist the tactician, commander, planner, and designer in optimizing aircraft performance. Load factor versus velocity (G-V) and altitude versus Mach number (H-M) diagrams are employed to obtain the interacting energy relationships fundamental to· energy-maneuverability theory. The G-V diagrams provide a measure of instantaneous maneuverability while the H-M diagrams (the most valuable diagrams) show sustained maneuverability as a function of energy rate, g, efficiency, and range throughout an aircraft's performance envelope. The energy diagrams, as the working totals of energy-maneuverability theory, may be used to determine operational maneuverability and efficiency of various armament-engine airframe combinatious.
