Book Description
A flight investigation was made of a rocket-launched ram-jet engine incorporating an inlet designed for a Mach number of 4.1 and burning magnesium slurry fuel. In free-flight, the model accelerated from an Mach number of 1.73 and an altitude of 5,900 feet until burnout at a Mach number of 3.84 and an altitude of 38,100 feet in an elapsed time of 13.2 seconds. Maximum values of acceleration (6.1 g), air specific impulse (150 seconds), and gross thrust coefficient (0.760) were obtained. The value of fuel specific impulse was 770 seconds.
