The SAM-QR is an Electro Mechanical Single Shot Safety and Arming Mechanism (SAM) designed for QR-SAM (Quick Reaction Surface-to-Air Missile) airborne applications. It ensures secure arming and reliable warhead detonation upon receipt of a valid command. The system is triggered by Armament On-Board Computer (AOBC) signals and incorporates multiple built-in safeties. The rotor-based Arming and Detonation Mechanism (ADM) and dual-redundant acceleration sensing contribute to safe missile operation during handling, storage, transportation, and launch.

Operation Mode :
- Safe Mode:Ensures the SAM remains unarmed to prevent unintentional detonation.
- Arm on Launch:System arms automatically after detecting launch conditions using setback and acceleration forces.
- ECU-Based Detonation:ADM detonates upon receiving valid firing signals from the ECU.
- Redundant Sensing:Employs both electrical and mechanical acceleration sensing to enhance operational reliability.
- Digital Control Interface:Features 8 digital isolated inputs and 4 outputs for configurable mission logic.
Fuze Safety:
The SAM physically blocks the detonation train until all arming conditions are met. Even if a signal is accidentally received, detonation cannot occur unless the rotor mechanism completes alignment, ensuring fault-tolerant operation.
Distant Arming:
Remote arming is achieved post-launch by sensing acceleration and setback forces. This ensures the SAM remains inert and safe during non-operational phases.
FUZE ACTION:
SAM-QR detonates the warhead following confirmation of arming and reception of a valid ECU trigger signal. It enables fast, controlled activation in operational scenarios.
