ABSTRACT:
An improved ejector ramjet includes a nozzle and propulsion duct. The nozzle has first and second sides, which are preferably two-dimensional, and produces a primary fluid jet which causes secondary fluid to be entrained in the propulsion duct. The primary jet is oscillated providing energy exchange between the primary and secondary fluids in the propulsion duct in a substantially non-viscous fashion.
