This report considers the cruise performance of a jet-propelled aircraft at high speed. The two problems of cruise with maximum range and with maximum endurance are analyzed. In each problem, for any given aircraft aerodynamics and engine characteristics, the equation for determining the optimum Mach number for cruise is derived. For maximum range, there exists an optimum cruise altitude. For the maximum endurance problem, the effect of the altitude on performance is negligible. It is shown that in both problems, constant Mach number cruise is a satisfactory flying technique. In the true optimum solution the optimum Mach number slowly decreases along the flight path. In this case, the singular thrust control is obtained explicitly as function of the Mach number. (Author)
