Radiatively driven hypersonic wind tunnel [PDF]
25th Plasmadynamics and Lasers Conference, 1994 This paper outlines a new approach to the design of hypersonic wind tunnels. This new approach is motivated by fundamental limitations of conventional isentropic expansions that arise from the very high temperatures required to achieve the necessary enthalpy for hypersonic flow.
