On-Board Oxygen Generating System (OBOGS):

The Defence Bio-Engineering & Electro Medical Laboratory (DEBEL) under DRDO successfully conducted high-altitude trials of the Indigenous On-Board Oxygen Generating System (OBOGS)-based Integrated Life Support System (ILSS) for the LCA Tejas aircraft.

• About: OBOGS-based 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.

o The ILSS met stringent aeromedical standards under various flight conditions, including taxying, takeoff, cruise, G-turns, rejoin approach, and landing.

• Performance evaluations covered: Oxygen concentration and demand breathing → Availability of 100% oxygen → Aerobatic maneuvers and full functional testing of the Anti-G Valve and Breathing Oxygen System (BOS).
• The ILSS integrates 10 Line Replaceable Units (LRUs), including: Low-Pressure Breathing Regulator, BOS, Emergency Oxygen System, Oxygen Sensor, Anti-G Valve, and other advanced components.
