DRDO holds trial of life support system for Tejas

The Defence Research and Development Organisation (DRDO) has successfully conducted high-altitude trials of the indigenous on-board oxygen generating system (OBOGS)-based integrated life support system (ILSS) for the Tejas fighter aircraft. This is a critical component for survival of pilots during flying.

Developed by DRDO’s Defence Bio-Engineering and Electro Medical Laboratory, the OBOGS-ILSS is a cutting-edge system designed to generate and regulate breathable oxygen for pilots during flight, eliminating dependence on traditional liquid oxygen cylinder-based systems.

The ILSS has 90 per cent indigenous content. With appropriate modifications, the system can also be adapted for use in the MiG-29K and other aircraft. The ILSS underwent rigorous testing on the Tejas’ Prototype Vehicle-3 aircraft of Hindustan Aeronautics Limited, meeting the required aeromedical standards in varied flight conditions, including altitudes of up to 50,000 feet above mean sea level, a defence spokesperson said.
