Air Force Tejas Mk1A: News & Discussions: 02 January 2022

[uddu]

Indigenous Ejection Seat development | Canopy Jettison system
Canopy severance hardware
Pyrobolts / explosive bolts (shear and separation) or distributed micro-charges.
Frangible tear seams or pre-weakened segment lines (so panels separate cleanly).
Linear cutting charges (LCC) vs. segmented pyro approach (pyrobolts + pop-out).
Canopy propulsion / ejection actuators
Gas thrusters, mortar charges, or small rockets to propel panels/segments clear of the airstream.
Sequencing & timing
Canopy sever → seat rocket(s) → drogue → main chute. Timing resolution in milliseconds.
Sensors (airspeed, altimeter, attitude) and an independent, redundant logic box.
Mechanical retention & release
Bolt shear calculations, redundancy, failsafes to prevent inadvertent jettison.
Safety & EMI / environmental hardening
EMI/EMP immunity, thermal range, long storage life, maintenance/inspections.
Test infrastructure
Sled tests, wind-tunnel/CFD, vertical tower tests, instrumented anthropomorphic dummies, high-speed cameras.
