DRDO Conducts High-Altitude Trial of Integrated Life Support System for Tejas Aircraft

The Defence Research and Development Organisation (DRDO) has successfully conducted a high-altitude trial of an indigenous Integrated Life Support System (ILSS) for the Light Combat Aircraft (LCA) Tejas. This On-Board Oxygen Generating System-based (OBOGS) ILSS eliminates the need for conventional liquid oxygen cylinders by generating and managing breathable oxygen for aircrew during flight. The trial, conducted by the Defence Bio-Engineering & Electro Medical Laboratory (DEBEL) in Bengaluru, demonstrated the system’s capability under extreme conditions, paving the way for its implementation in other aircraft such as the MiG 29K.

Key Highlights
