Abstract: A scheme of trans-medium ramjet engine which can work in both air and water with the same metal solid propellant is proposed to satisfy the application requirements of air-water integrated trans-medium missiles. We study the influence of the solid propellant formulation, air/water fuel ratio and metal type on the theoretical performance of trans-medium ramjets, followed by the selection of the design parameters of the engine with a given flight trajectory of the trans-medium missile and the metal based solid propellant. The operating parameters of the engine working in both air and water are obtained, theoretically verifying the feasibility of the scheme of trans-medium ramjets.

Key words: trans-medium, ramjet, theoretical performance, design parameters, configuration scheme
