Pyrotechnic actuator for fast action as electrical protection in HVDC aerospace application
AIR7258
The scope of this report is first to establish applicable definitions and terms prior to considering the application domain and use cases in HVDC applications. Then it will describe the specificities of pyrotechnic actuator for use within a power switching device with order of magnitude in term of performances and main characteristics to consider for aerospace application.
Rationale: Future aircraft programs employs high voltage direct current (HVDC) as primary sources of electric power.
In these conditions, Electrical fault clarification requires fast acting switching devices to protect the aircraft electrical installation and limit potential damages.
The intent of this Aerospace Information Report (AIR) is to gather information and define characteristics for the usage of pyrotechnic actuator or initiator for fast action as electrical protection in High Voltage Direct Current aerospace application.
