The SAM-ASTRA is an Electro Mechanical Safety and Arming Mechanism (SAM) designed for airborne missile payloads. It acts as a critical interface between the missile and warhead, ensuring complete safety during handling, transportation, storage, and launch. SAM-ASTRA features a rotor-based Arming and Detonation Mechanism (ADM), dual-redundant acceleration sensing, and programmable digital interfacing to support secure mission operation.

Operation Mode :
- Safe Mode:The mechanism remains unarmed to prevent any accidental detonation during non-operational conditions.
- Trigger Signal Arming:SAM-ASTRA arms and detonates upon receiving a firing pulse from the ECU based on inputs from the Radio Proximity Fuze or Command Destruction system.
- Rotor-Based Arming:A mechanical rotor isolates the explosive path and aligns only after validating arming conditions.
- Dual-Redundant Acceleration Sensing:Ensures safe and secure arming by verifying both electrical and mechanical sensor inputs.
- Digital Signal Interface:Equipped with 8 digital isolated inputs, allowing programmable control for mission-specific arming configurations.
Fuze Safety:
The SAM-ASTRA design ensures the firing path remains blocked prior to valid launch conditions. Even in the event of unintentional primer ignition, the firing train is not activated, ensuring full safety.
Distant Arming:
Arming is enabled only after post-launch validation through detection of acceleration and setback forces. This guarantees the SAM remains unarmed until missile launch and separation are confirmed.
FUZE ACTION:
SAM-ASTRA initiates detonation by confirming acceleration and impact through dual-redundant sensors. Activation is carried out only under securely defined mission parameters.
