Indigenous Oxygen Generating System for LCA Tejas

The Defence Bio-Engineering & Electro Medical Laboratory (DEBEL) has achieved milestone in defence technology with the successful high-altitude trials of the Indigenous On-Board Oxygen Generating System (OBOGS)-based Integrated Life Support System (ILSS) for the LCA Tejas aircraft. Conducted on 4 March 2025, this trial marks important advancement in ensuring pilot safety and performance during high-altitude flights.

What is OBOGS?

OBOGS provides a reliable method for generating oxygen onboard an aircraft. This system eliminates the need for traditional liquid oxygen cylinders. OBOGS uses a technology called ‘zeolite molecular sieve’ to separate oxygen from air. This technology enhances efficiency and reduces logistical burdens.

Features of the Integrated Life Support System

The ILSS integrates multiple components to ensure optimal functioning. It includes the Low-Pressure Breathing Regulator, Emergency Oxygen System, and Anti-G Valve. The system can generate 100% oxygen, ensuring pilots have sufficient breathable air during high-G maneuvers. It is designed to operate at altitudes of up to 50,000 feet.

Testing and Performance Evaluation

The ILSS underwent rigorous testing on the LCA-Prototype Vehicle-3 aircraft. This testing assessed oxygen concentration, demand breathing, and aerobatic maneuvers. The system met stringent aeromedical standards. It performed well in various flight conditions, ensuring pilot endurance and operational effectiveness.

Indigenous Content and Collaboration

The ILSS boasts 90% indigenous content, reflecting India’s commitment to self-reliance in aerospace technology. The system was developed through collaboration among several entities, including DEBEL, HAL, and the Indian Air Force (IAF). This partnership strengthens India’s defence capabilities and promotes local industry.

Adaptability and Future Prospects

With appropriate modifications, the ILSS can be adapted for use in other aircraft, such as the MiG-29K. This adaptability enhances its utility across different platforms. The successful trials position India to integrate advanced life support systems in future military aircraft.

Significance

The development of the OBOGS-based ILSS represents a leap forward in military aviation. It reduces reliance on ground support for oxygen supply. This innovation enhances the operational readiness of aircraft and improves safety for pilots during high-altitude missions.
