The Indian Space Research Organisation (ISRO) has successfully developed a 10-tonne propellant mixer for solid motors, marking a major advancement in India’s space technology.
Solid propulsion is a key component of India’s space transportation systems, and precise mixing of solid propellants is essential due to the sensitive and hazardous nature of the ingredients involved. The vertical planetary mixer is a critical piece of equipment in solid motor production, ensuring the efficient and uniform blending of propellants.
To enhance the production scale of solid motor segments, the Satish Dhawan Space Centre (SDSC), Sriharikota, in collaboration with the Central Manufacturing Technology Institute (CMTI), Bengaluru, has successfully designed and developed this state-of-the-art 10-tonne Vertical Planetary Mixer.
ISRO described the indigenous mixer as a significant technological milestone, calling it the largest solid propellant mixing equipment in the world. The development involved partnerships with academia and industries, and the system has already passed factory-level acceptance tests.
This high-capacity mixer is expected to improve productivity, quality, and efficiency in heavy solid motor production, reinforcing India’s self-reliance in critical space technologies.
The Department of Space has been actively working towards indigenizing critical technologies, materials, and machinery under the Atmanirbhar Bharat (self-reliance) initiative. The successful realization of the 10-tonne vertical mixer is a testament to India’s growing technological strength and commitment to innovation.
On Thursday, the mixer was officially handed over to the Director of SDSC SHAR by the Director of CMTI, in the presence of ISRO Chairperson V. Narayanan, at CMTI, Bengaluru.
With this breakthrough, India has cemented its position as a leader in space technology, further strengthening its ability to manufacture and deploy advanced solid motors for upcoming space missions.
