Abstract : The performance was studied of a typical missile design utilizing four different types of blow-off cowl ramjet engines. Comparisons are made with vehicle performance using conventional ramjet engines. The results show no worthwhile performance gain with any of the blow-off cowl engines even for the favorable case where they are installed on a relatively clean low drag airframe of the X-7 type. Although, percentage-wise, large thrust increases are possible with normal shock blow-off cowls, the thrusts were still too low for practical application on existing or proposed missile designs.
