Abstract: Combustion of tapes in air, rolled from titanium powder, and the delay time of the combustion front motion in the presence of a one-sided partition, which limits the access of an oxidizer to the surface. It is shown that the combustion front is aligned with respect to the tape thickness at a long distance from the partition, which is two order of magnitude larger than its thickness. The critical width of the two-sided partition is determined. The largest portion of the tape, where the front is aligned with respect to the tape thickness with a one-sided partition, and the small critical width of the two-sided partition are due to the surface combustion.

Keywords: filtering and surface combustion, burning rate of titanium tapes, effect of partition.
