SAM-RDM is an Electronic Safety Arming Mechanism designed to integrate multiple safeties and initiate warhead detonation as required. The mechanism features dual-redundant impact and acceleration sensing for enhanced reliability. Used in missile payload applications, SAM-RDM operates in conjunction with the Electronic Control Unit (ECU) to arm and detonate the ADM explosive train. It ensures safety during handling, transportation, storage, and launch phases, guaranteeing reliable operation under all environmental conditions.

Operation Mode :
The SAM-RDM features multiple operation modes to ensure safe and reliable arming and detonation under different mission conditions. These modes are selectable via the system’s control interface:
- Safe Mode:: The system remains unarmed to prevent any accidental detonation during handling, transport, or storage.
- Arm on Launch:The SAM arms automatically after sensing the launch event through acceleration and setback forces.
- Impact Detonation Mode:The warhead detonates immediately upon detecting an impact via dual-redundant impact sensors.
- Delayed Detonation Mode:Detonation occurs after a preset delay following impact, selectable to allow for either short or long delay times.
- Remote Arming Mode:The SAM can receive arming commands via the Electronic Control Unit (ECU) through its digital inputs.
Fuze Safety:
Before launch, the Safety Arming Mechanism prevents the warhead detonator from activating the firing train. Even if the primer ignites unintentionally, no firing pulse is transferred to the explosive train, ensuring complete safety during handling, transport, and storage.
Distant Arming:
The SAM-RDM arms remotely after detecting launch through setback and acceleration forces. This ensures that the mechanism remains safe until the missile is in flight and the arming conditions are met.
FUZE ACTION:
The SAM-RDM functions by sensing impact and acceleration forces through its dual-redundant sensors. It ensures reliable detonation upon impact with the target or after a preset delay, depending on the selected operation mode. The mechanism supports immediate (super-quick) or delayed detonation options for operational flexibility.
