AI Technical Summary
Technical Problem
Existing pyrotechnic cartridges in aircraft are vulnerable to untimely ejection during electromagnetic interference, such as lightning strikes, leading to potential catastrophic effects due to simultaneous and untimely firing of decoys.
Method used
A launching structure for pyrotechnic cartridges is designed with an insulator to electrically isolate the pyrotechnic ejection system from the socket, using materials like parylene for insulation, ensuring the system is not activated by external electric currents.
Benefits of technology
The insulator effectively protects the pyrotechnic cartridges from accidental triggering during electromagnetic attacks, providing reliable operation and meeting stringent design standards while being simple and cost-effective.

Abstract
- Launching structure for a pyrotechnic cartridge and pyrotechnic cartridge equipped with such a launching structure. - The launching structure (2) comprises a socket (3) and a pyrotechnic ejection system (4), the pyrotechnic ejection system (4) being activated by the application of an electric current and being mounted in a housing (9) provided at one end (3A) of the socket (3) and being accessible from the outside, the interface (10) between the pyrotechnic ejection system (4) and the socket (3) being provided with an insulator (11) which is configured to completely electrically isolate the pyrotechnic ejection system (4) from the socket (3) so that in the event of electromagnetic interference such as a lightning strike, which could generate an electric current which tends to propagate in the socket (3), the pyrotechnic ejection system (4) is not impacted by this electric current and is not at risk of being activated unintentionally.
