A study has been conducted to determine the implications of top-mounted inlet nacelles on propulsion performance and cruise range. The top-mounted nacelle would be less visible from ground-based radar below and ahead of the aircraft. For this study, the nacelle is integrated with a high altitude Mach 5 turbojet/ramjet-powered airplane concept requiring a large nacelle. Results of the study suggest nacelle installation advantages and improved inlet mass flow ratio for the top-mounted nacelle, but at the expense of a higher installed drag at transonic and supersonic speeds.
