Abstract
A high-performance propulsion system includes propellant charge powder arranged in a case (1) and multiple pyrotechnic igniters (9) for igniting the propellant charge powder, each igniter (9) containing a primer (5) and optionally a booster charge (6).
Claims13
High-performance propulsion system, comprising:
- a case;
- propellant charge powder arranged in the case;
- a plurality of pyrotechnic igniters arranged in the case for igniting the propellant charge powder, each of the pyrotechnic igniters including a primer and a programmable electronic unit in which an individual address is stored;
- an igniter element connectable to a fire control computer;
- and
- at least one two-conductor or multi-conductor bus line connecting the plurality of pyrotechnic igniters to the igniter element.

A method for igniting a high-performance propulsion system, comprising a case, propellant charge powder arranged in the case, a plurality of of the pyrotechnic igniters including a primer and a programmable electronic unit in which an individual address is stored;
- an igniter element connectable to a first control computer;
- and at least one two-conductor of multi-conductor bus line connecting the plurality of pyrotechnic igniters to the igniter element, the method comprising:
- ascertaining the temperature of the propellant charge powder and forwarding it to the fire-control computer;
- reading properties of the propellant charge powder stored in the electronic unit, and forwarding those data to the fire-control computer;
- determining, in the fire-control computer, the number and sequence in time of the pyrotechnic igniters to be ignited, and programming those pyrotechnic igniters;
- delivering an ignition pulse to the pyrotechnic igniters.
