Hindustan Aeronautics Limited (HAL) inching towards a significant milestone in its indigenous engine development program. The company that had commenced Limited Series Production of the HTSE-1200 engine, sometime back that is set a powerful turbo-shaft powerplant designed to propel medium-sized helicopters.
The first batch of HTSE-1200 engines is expected to be delivered by mid-2025. Currently, 5 HTSE-1200 engines are in the fabrication stage, with the first engine slated for delivery next year.
Developed by the HAL Engine Division at Koraput in association with the Defense Metallurgical Research Laboratory (DMRL), the HTSE-1200 engine has undergone rigorous testing and development. Prototypes of the engine have completed the manufacturing of parts and modular assemblies for the Power Mode engine. Notably, the core of the engine has demonstrated 100% RPM, a crucial benchmark for its performance.
HAL plans to use the HTSE-1200 engine to test it on an older Prototype of the ALH-Dhruv, a widely used Indian-designed and manufactured helicopter. The 1200KW Turbo-shaft engine would be used as the powerplant for helicopters in the 3 to 6-ton category.
To further validate the engine’s capabilities, one technology demonstrator of the HTSE-1200 engine was built and went through rigorous testing. This demonstrator has achieved a 100% speed run on the core engine and has completed sea-level trials.
The development of the HTSE-1200 engine marks a significant step towards India’s self-reliance in aerospace technology. It demonstrates the country’s capability to design and manufacture advanced propulsion systems for its military and civilian aircraft. As HAL continues to refine and produce the HTSE-1200 engine, it will play a vital role in powering India’s helicopter fleet and supporting the country’s defence and aerospace industries.
