Design of a 3D shape transitioning nozzle and experimental thrust measurements of an airframe integrated scramjet

Abstract

The scramjet engine provides the means for airbreathing propulsion at flight speeds exceeding Mach 5. As part of a three-stage-to-orbit system it is envisioned to play a major role in sustainable access-to-space. When compared to a rocket engine, scramjets offer a higher specific impulse and increased mission flexibility through the manoeuverability of the vehicle.
