Pyrotechnic device

Abstract

Parachutes for signalling rockets, for example, open in a jerky manner, as a result of which the suspension lines (13) are exposed to a heavy load. The invention envisages two suspension lines (14) configured in an extensible, particularly rubber-band-like manner, as a result of which the initially effective parachute surface area is reduced, which causes the parachute canopy (12) of the parachute (10) to open more slowly than with previous parachutes (10), which in turn reduces the opening jerk of the parachute (10). In this way, the suspension lines (13, 14) in particular, but also the parachute canopy (12) of the parachute (10), are subject to less load.
