Indigenous Life Support System for LCA Tejas Aircraft

The Defence Bio-Engineering & Electro Medical Laboratory (DEBEL) in Bengaluru has made advancements in aviation technology. On March 4, 2025, DEBEL successfully conducted high-altitude trials of the Indigenous On-Board Oxygen Generating System (OBOGS)-based Integrated Life Support System (ILSS) for the Light Combat Aircraft (LCA) Tejas. This system enhances pilot safety and performance during flight operations.

Overview of the Integrated Life Support System

The ILSS is designed to generate breathable oxygen for pilots. It eliminates the need for traditional liquid oxygen systems. This innovation allows pilots to operate effectively at high altitudes. The system is crucial for missions that require high-G maneuvers and extended flight times.

High-Altitude Trials

The ILSS underwent rigorous testing on the LCA-Prototype Vehicle-3. It was evaluated under extreme conditions, reaching altitudes of 50,000 feet. The trials assessed oxygen concentration, demand breathing, and the availability of 100% oxygen. The system was tested during various flight phases including take-off, cruising, and landing.

Components of the Integrated Life Support System

The ILSS integrates ten Line Replaceable Units. Key components include the Low-Pressure Breathing Regulator, Breathing Oxygen System (BOS), Emergency Oxygen System, and Anti-G valve. These components work together to provide real-time oxygen generation. This enhances pilot endurance and operational effectiveness.

Indigenous Manufacturing and Collaboration

The ILSS boasts 90% indigenous content, showcasing India’s commitment to self-reliance in aerospace technology. The system was developed in collaboration with various entities including Hindustan Aeronautics Limited (HAL) and the Aeronautical Development Agency (ADA). This partnership reflects step towards advancing India’s defence capabilities.

Future Adaptability and Applications

The ILSS can be adapted for use in other aircraft such as the MiG-29K. This adaptability ensures that various platforms can benefit from the advanced life support technology. The ongoing development signifies the potential for broader applications in military aviation.

Recognition and Future Vision

The successful trials of the ILSS have been acknowledged by Defence Minister Shri Rajnath Singh and DRDO Chairman Dr Samir V Kamat. They brought into light the achievement as a testament to India’s dedication to cutting-edge defence technologies. This aligns with the vision of ‘Viksit Bharat 2047’, aiming for a developed India.
