Circular Spalakh
Charge Initiation Device
CIRCULAR SPALAKH is a multifunctional initiation device primarily designed for interceptor and deep-strike UAVs, providing controlled warhead detonation through contact or non-contact munition initiation.
The built-in accelerometer rapidly detects collisions with hard and soft targets. The device supports configurable initiation modes and algorithms, commands received via PWM and UART, and operation using a self-destruct timer.
Device status and timer values can be displayed on an OSD when integrated with flight controllers running Betaflight or ArduPilot.
