New article reproducing a Johns Hopkins study of a strategic ram jet missile done for the Air Force in August 1946 is now up on RetroMechanix.com:
The study examines the powered range of a family of ram-jet propelled vehicles to determine the effect of various propulsion parameters and schemes. The accompanying gallery features 9 images, including inboard profiles and artwork of the 4 configurations considered. Each configuration was evaluated in 3 sizes, ranging from 40 to 80 ft in length. Note the unusual reverse delta wing, which showed promise at the time but has since been largely abandoned. Would make for an interesting scratchbuilding subject!
