The objective of this analysis was to select a rocket design which would decelerate a B-1 escape capsule drop test vehicle to a vertical velocity of 10 ft/sec or less at capsule impact with the terrain. The concept is based on the prediction that if the capsule is decelerated to a vertical velocity of 10 ft/sec or less at impact, the capsule occupants would not be subjected to accelerations which exceed the requirements of MIL-C-25969B. The results of a parametric study which considered thrust to weight ratios of 2 through 10, in combination with recovery system descent rates of 30 through 60 ft/sec, are presented. The test envelopes which could be accommodated with two different off-the-shelf rocket systems are presented. The analytical method employed in determining the test envelopes is discussed. Performance summaries for the selected rocket system are given. (Author)
