The Defence Research and Development Organisation (DRDO) has achieved a significant breakthrough in India's aerospace sector with the successful development of high-pressure compressor (HPC) drums for aero engines.

This advancement, led by the DRDO's Defence Metallurgical Research Laboratory (DMRL) in Hyderabad, represents a major step towards self-sufficiency in defense manufacturing, reducing the country's reliance on foreign suppliers for these critical components.

HPC drums are essential to aero engines, operating under intense pressure and extreme heat. Timely replacement is crucial for ensuring engine safety and maintaining peak performance. Until now, India depended heavily on imports for these expensive, high-value parts.

The DMRL scientists succeeded in developing a specialized forging process that incorporates various scientific and engineering tools to produce compressor drums that meet the stringent demands of aero engines.

This innovative process not only facilitates the production of HPC drums but can also be adapted to manufacture other complex components for aero engines.

The indigenously produced compressor drums have undergone extensive testing and certification, including assessments by the Indian Air Force, which confirmed their quality, durability, and performance.

This achievement highlights the collaborative efforts of several key organizations, including Hindustan Aeronautics Limited (HAL), Mishra Dhatu Nigam Limited (MIDHANI), the Centre for Military Airworthiness and Certification (CEMILAC), and the Directorate General of Quality Assurance (DGAQA).

This development holds significant implications for India's aerospace industry, enhancing the nation’s capability to produce critical components for advanced military aircraft. It strengthens India's defense infrastructure and further reduces its dependence on foreign imports.
