The Indian Space Research Organization (ISRO) has achieved a significant milestone in its pursuit of self-reliance in the space sector. On February 13, 2025, ISRO announced the successful development of a 10-tonne Vertical Planetary Mixer, the largest of its kind globally for solid propellants. Designed and manufactured in collaboration with the Central Manufacturing Technology Institute (CMTI) in Bengaluru, this groundbreaking equipment is set to revolutionize the production of solid rocket motors.
Significance of Solid Propulsion
Solid propulsion plays a crucial role in India’s space transportation systems, requiring precise mixing of sensitive and hazardous ingredients. The newly developed vertical mixer significantly enhances the efficiency and safety of this process. Improved mixing capabilities will result in higher quality propellants, a critical factor in the success of future space missions.
Technical Specifications of the Mixer
- Weight: 150 tonnes
- Dimensions: 5.4 metres in length, 3.3 metres in breadth, and 8.7 metres in height
- Agitators: Multiple hydrostatically driven agitators for superior mixing
- Control System: Remotely operated PLC-based system integrated with SCADA stations for precision control
This cutting-edge technology ensures meticulous mixing, crucial for achieving the desired propellant consistency and performance.
Collaboration and Development Process
The project was spearheaded by the Satish Dhawan Space Centre (SDSC) in collaboration with CMTI. The development process involved partnerships with leading academic institutions and industry experts. The successful completion of factory-level acceptance tests confirms the mixer’s operational efficiency, marking another step forward in India’s space technology advancements.
Impact on Indian Space Missions
The introduction of this vertical mixer is expected to transform the production of solid rocket motors, leading to enhanced productivity and throughput. This advancement aligns with India’s broader initiative to achieve self-reliance in critical space technologies. ISRO’s relentless commitment to innovation and technological development is evident in this achievement, reinforcing India’s position as a leader in space exploration.
With the successful deployment of this mixer, ISRO is well-positioned to further strengthen its space capabilities, paving the way for more ambitious and technologically advanced missions in the future.
