In this paper, an exhaust Omuser was designed by numerical calculation software according to the requirement of the two-dimensional ramjet experiments. The new diffuser could make the best of the gas energy, send up the simulative altitude, economize energy and enlarge the working range of altitude simulation test facility. Finally, the best diffuser structural form, structural parameter and the distances between the nozzle outlet and the diffuser inlet were determined.
