Abstract
The present invention relates to pyrotechnic flares. A hollow support structure (1) receives a first pyrotechnic composition (2) with a delay action internally and axially, whereas it receives a second pyrotechnic composition (4) which is slower than the first, in holes (101 to 151), arranged radially and of decreasing length. An initiator (3) initiates the composition (2) on the side where the radial through-holes are longest. Located outside is an illuminating composition (5), which may thus be illuminated virtually at the same time over the entire length of the product. Application in particular as an optical or infra-red counter-measure.
