In a significant step towards enhancing India’s aerospace capabilities, the Gas Turbine Research Establishment (GTRE) has made substantial progress with the construction of its 130kN Twin Engine Test Bed Facility at Rajankunte, Bengaluru. This facility, now nearing completion, is set to play a pivotal role in the development of critical engine projects such as the dry Kaveri engine and the engine for the Advanced Medium Combat Aircraft (AMCA).
The new test bed facility is designed to accommodate engines with thrust levels up to 130kN, providing a platform for rigorous testing and validation of high-performance jet engines. The construction, which commenced with groundwork in September 2023 following consultancy work in July of the same year, is part of a broader initiative by the DRDO to bolster India’s self-reliance in aerospace technology.
The dry Kaveri engine, with its development targeting a thrust of around 46kN, stands to gain immensely from this facility. The test bed will allow for comprehensive ground testing, which is crucial for fine-tuning the engine’s performance, addressing previous technical issues, and ensuring it meets the stringent requirements for military use. This facility will enable GTRE to conduct endurance tests, performance evaluations, and necessary modifications to achieve the desired thrust levels and reliability.
For the AMCA, India’s ambitious fifth-generation fighter jet project, the test bed at Rajankunte will be indispensable. The AMCA engine, expected to deliver around 110kN of thrust, will undergo extensive testing here to ensure it can handle the extreme conditions of combat, including high-altitude and supersonic performance. The facility’s capabilities will facilitate the iterative development process, from prototype to production readiness, potentially reducing the time and cost associated with engine development.
The construction of this facility underscores the strategic direction India is taking towards indigenous defense production. It not only supports the Kaveri and AMCA programs but also paves the way for future engine developments, reducing dependency on foreign technology and enhancing national security through technological sovereignty. The test bed will also serve as a hub for innovation, potentially attracting collaborations with private sector entities and international partners interested in co-development opportunities.
With the project expected to be fully operational by October 2025, the GTRE is on track to significantly uplift India’s capabilities in gas turbine technology. The facility will not only aid in the immediate projects but will also lay down infrastructure for long-term advancements in aerospace engineering. As India aims to become a key player in global defense manufacturing, facilities like the one at Rajankunte are foundational to achieving those goals.
