Abstract
Computations indicate that when utilized in an idealized ramjet at a flight Mach number of 2.5 and an altitude of 37,500 feet, a constant area axial flow nuclear heat exchanger will be expected to produce 9,500 pounds of thrust with an air inlet Mach number of 0.2, a weighted radial temperature average of 2000°F and a frontal area of 7.7 square feet. Molybdenum alloy with a disilicide coating was selected as the container material. Sandwiched between the molybdenum was a fissionable alloy of highly enriched uranium and zirconium. From a nuclear aspect the unreflected heat exchanger becomes critical at a diameter of 40 inches and a length of 60 inches with a total weight of 8,052 pounds which includes 3,622 pounds of 90 per cent enriched uranium.
