DRDO Successfully Tests Indigenous Life Support System for Tejas Pilots at High Altitudes

The Defence Research and Development Organisation (DRDO) has achieved a significant milestone by successfully conducting high-altitude trials of an indigenous life support system for pilots onboard the Tejas Light Combat Aircraft (LCA). This cutting-edge system is designed to generate and regulate breathable oxygen during flight, eliminating the need for traditional cylinder-based oxygen supplies.

The trials were conducted on March 4, with the system undergoing rigorous testing aboard the LCA-prototype vehicle-3 aircraft developed by Hindustan Aeronautics Limited (HAL). It was assessed under various flight conditions, including altitudes of up to 50,000 feet above mean sea level and high-G maneuvers. Following clearance from the Centre for Military Airworthiness & Certification (CEMILAC), the system successfully met all performance parameters.

Developed by DRDO’s Defence Bio-Engineering & Electro Medical Laboratory (DEBEL) in Bengaluru, the Integrated Life Support System (ILSS) is based on the Indigenous On-Board Oxygen Generating System (OBOGS). This advanced technology ensures continuous oxygen supply to pilots, enhancing safety and endurance during long-duration and high-altitude missions.

With necessary modifications, the system can also be adapted for aircraft such as the MiG-29K, expanding its operational utility beyond the Tejas. Defence Minister Rajnath Singh congratulated DRDO, the Indian Air Force, public sector undertakings, and industry partners on this "remarkable achievement," stating that the innovation strengthens India's commitment to cutting-edge defence technology and aligns with the vision of 'Viksit Bharat 2047.'

The system, developed with 90% indigenous content, highlights India's progress toward self-reliance in aerospace technology. Larsen & Toubro (L&T), a key defence industry partner, has played a crucial role in its manufacturing, demonstrating successful collaboration between DRDO and private industry.

Samir V. Kamat, Chairman of DRDO, commended the entire team, the IAF, and industry partners for their contributions to the successful high-altitude trials, marking a significant step forward in India's aerospace capabilities.
