CSIR-NAL Unveils Indigenous Gas Turbine Engines for Defence

CSIR unveiled the three Indian-made Micro & Small Gas Turbine Engines on 25th August, 2026. NJ-05, NJ-50 and NJ-100 engines generate thrusts of 5kg, 50kg and 100kg respectively. These miniature engines have been developed by the CSIR National Aerospace Laboratories, and have been designed to be used in tactical UAVs, drone interceptors and compact missile systems.

Three Indigenously Developed Engines Launched

The unveiling ceremony took place at the SSB Auditorium at the CSIR Headquarters in New Delhi.

The engines are,

• NJ-05: 5 kg thrust
• NJ-50: 50 kg thrust
• NJ-100: 100 kg thrust

The need to develop such engines is due to the rising demand for compact and specific types of engines for unmanned and defense purposes.

Gas Turbine Engine Technology

Dr. R. Prathapanayaka led the technical presentation of the scientists from CSIR-NAL on the development. The technology uses the advancements in high-speed turbomachinery and high-temperature combustion systems.

The latter is especially crucial for compact gas turbine engines since it is technologically complicated to provide adequate performance in restricted size and weight conditions.

Possible Defence Uses

These indigenous engines are slated to be used in multiple uses, including tactical UAVs, drone interceptors, and small missile systems.

This development will aid in reducing reliance on imported propulsion systems for smaller unmanned and defence systems. It also opens up possibilities for Indian industry and aerospace start-ups in manufacturing these specific engines.

Atmanirbhar Bharat Initiative

Dr. Abhay A. Pashilkar, the CSIR-NAL Director, stressed the contribution of this laboratory towards the growth of the drone ecosystem of India. He also emphasized the potential of Indian industry and its aerospace start-ups in manufacturing these engines.

Dr. N. Kalaiselvi, the CSIR Director General, said that developing indigenous specialized and critical subsystems is a significant step for Atmanirbhar Bharat Initiative in aerospace engineering.

Strategic Significance for India

As per Air Marshal Tejinder Singh, Chief of Integrated Defence Staff to the Chairman Chiefs of Staff Committee, development of advanced gas turbine engines is of great strategic significance for India.

Having indigenous capability in important propulsion technologies can be significant from both national security and technological independence aspects for the Armed Forces.
