Vajra — Aircraft Pyrotechnics
Safety systems, ejection technology and pyrotechnic architecture for the Vajra.
The Vajra incorporates a comprehensive pyrotechnic architecture to ensure pilot survivability and aircraft safe-separation from stores across the entire flight envelope.
The Martin-Baker India Mk16I zero-zero ejection seat, manufactured under licence at IndoFighter's Bengaluru facility, provides safe ejection from zero altitude / zero speed to 900 km/h IAS at sea level and from speeds up to Mach 1.8 at high altitude. The seat incorporates an advanced parachute sequencer that adapts deployment to detected altitude and velocity.
The Vajra uses a rocket-assisted canopy jettison system that clears the canopy within 0.12 seconds of initiation, either ahead of ejection or in isolation for emergency ground egress. The canopy fracture pattern is designed to prevent fragments entering the ejection path.
All 14 hardpoints are equipped with cartridge-actuated ejector release units (ERUs) capable of safe emergency jettison of stores from all points of the flight envelope. A sequential jettison logic, managed by the stores management system, prevents asymmetric loading during emergency jettison.
Each engine bay is equipped with two halon-free fire extinguisher bottles, automatically activated by dual infra-red fire detectors. The Vajra's fire detection system also covers the air intake trunking, avionics bays and fuel collector tanks.
