ISRO Develops World’s Largest Vertical Propellant Mixer

February 18, 2025

The Indian Space Research Organization (ISRO) has made advancement in its quest for self-reliance within the space sector. On February 13, 2025, ISRO announced the successful development of a 10-tonne Vertical Planetary Mixer, the largest of its kind for solid propellants globally. This innovative equipment was designed and manufactured in collaboration with the Central Manufacturing Technology Institute (CMTI) in Bengaluru. This development is poised to enhance the production of solid rocket motors.

Significance of Solid Propulsion

Solid propulsion is vital for India’s space transportation systems. Solid rocket motors require precise mixing of sensitive and hazardous ingredients. The new vertical mixer will improve the efficiency and safety of this process. Enhanced mixing capabilities will lead to better quality propellants, which are essential for the success of space missions.

Technical Specifications of the Mixer

The vertical mixer has a weight of 150 tonnes. It measures 5.4 metres in length and has dimensions of 3.3 metres in breadth and 8.7 metres in height. It features multiple hydrostatically driven agitators. The system is remotely operated through a PLC-based control system integrated with SCADA stations. This advanced technology ensures precision in the mixing process, crucial for solid propellant production.

Collaboration and Development Process

The project was a collaborative effort between the Satish Dhawan Space Centre (SDSC) and CMTI. The development involved partnerships with academia and industry experts. Factory-level acceptance tests have been successfully completed, confirming the mixer’s operational capabilities. This teamwork reflects India’s commitment to encouraging innovation in space technology.

Impact on Indian Space Missions

The introduction of the vertical mixer is expected to revolutionise the production of solid rocket motors. It will enhance productivity and throughput. This advancement aligns with India’s broader initiative to achieve self-reliance in critical technologies. ISRO’s commitment to innovation is evident in this project, marking another milestone in India’s space capabilities.
