The performance of redundant pyrotechnic delays is analyzed. It is found that the average delay time of a redundant cluster of delays is shorter than the corresponding average of the individual delays. Also, the standard deviation of the cluster delay time is smaller than the corresponding individual delay standard deviation. These two effects are found to be monotonic functions of the number of delays in the cluster. The effect of the delay reliability on the cluster statistics is shown to be qualitatively similar to a reduction in the effective cluster size.
