DRDO Achieves Major Breakthrough in Fighter Aircraft Escape System Testing

The Defence Research and Development Organisation (DRDO) has achieved a major milestone by successfully conducting a high-speed rocket-sled test of a fighter aircraft escape system at controlled velocity. 

The test took place at the Rail Track Rocket Sled (RTRS) facility of the Terminal Ballistics Research Laboratory (TBRL) in Chandigarh. 

This critical trial validated key components of the emergency escape system, including canopy severance, ejection sequencing, and full aircrew recovery, marking a significant achievement in India’s defence technology capability.

Collaboration with ADA and HAL

The dynamic test was carried out in close coordination with the Aeronautical Development Agency (ADA) and Hindustan Aeronautics Limited (HAL). This accomplishment positions India among the select group of nations equipped with advanced, indigenous escape-system testing infrastructure. Such capabilities are vital for ensuring pilot safety in modern fighter aircraft and align with India’s broader goals of self-reliance in defence technology.

Complexity of Dynamic Ejection Tests

Dynamic ejection tests are far more sophisticated than conventional static evaluations such as the Net Test or Zero-Zero Test. They represent the true benchmark for assessing ejection seat reliability and the effectiveness of canopy severance mechanisms. 

In this test, a dual-sled system carrying the forebody of the Light Combat Aircraft (LCA) was accelerated to a precisely controlled velocity using multiple solid-propellant rocket motors fired in phases.

To accurately simulate real-world pilot conditions, engineers used an instrumented Anthropomorphic Test Dummy (ATD). The dummy captured vital data, including loads, moments, and acceleration forces that an actual pilot would experience during an emergency ejection. 

The entire sequence was documented through onboard sensors and ground-based high-speed imaging systems. Officials from the Indian Air Force (IAF) and the Institute of Aerospace Medicine were present to witness and oversee the certification aspects of the test.

Leadership Applauds the Milestone

Defence Minister Rajnath Singh congratulated DRDO, IAF, ADA, HAL, and industry partners, calling the achievement a major step towards strengthening India’s indigenous defence ecosystem. DRDO Chairman Dr. Samir V. Kamat also praised the teams involved for their commitment and technical excellence.

Conclusion

The successful high-speed rocket-sled test advances India’s capability in aircraft safety systems and reinforces the nation’s drive toward indigenous, world-class defence technologies. It marks a crucial stride in ensuring pilot safety and enhancing the self-reliance of India’s aerospace sector.
