ISRO develops 10-tonne propellant mixer for solid motors
Bengaluru (PTI): ISRO on Friday said it has developed and realised the ten-tonne propellant mixer for solid motors.
Solid propulsion plays a crucial role in Indian Space Transportation Systems and vertical mixer is one of the critical equipment in solid motor production, ISRO said in a statement.
"Solid propellants are the backbone of rocket motors, and their production requires precise mixing of highly sensitive and hazardous ingredients," the statement read.
The space agency said that towards increasing the production scale of solid motor segments, Satish Dhawan Space Centre in Sriharikota in collaboration with Central Manufacturing Technology Institute (CMTI), Bengaluru has successfully designed and developed 10-tonne Vertical Planetary Mixers for processing the solid propellants.
ISRO has termed it a significant technological marvel. It added that the 10-tonne vertical mixer is the world's largest solid propellant mixing equipment.
The development involves collaboration with academia and industries and has completed factory-level acceptance tests.
This high-capacity mixer will enable productivity, quality and throughput improvement for heavy solid motors production.
Stating that the Department of Space has undertaken multiple initiatives towards indigenous development of critical technologies, materials and machinery as part of ‘Atmanirbharata (self reliance) in Space’, ISRO said. "The realisation of indigenous 10-tonne vertical mixer is a true testament to India’s growing technological prowess, self-reliance and unwavering commitment to innovation," it added.
The 10 tonne vertical mixer is handed over to Director, SDSC SHAR by Director, CMTI in the presence of ISRO Chairperson V Narayanan on Thursday in CMTI, Bengaluru.
ISRO said the 10-tonne vertical mixer weighs about 150 tonnes with a length of 5.4 m, breadth of 3.3 m and height of 8.7 m.
The system has multiple agitators, which are hydrostatic driven and will be remotely operated using PLC-based control system with SCADA stations.

Liquor ban in MP's religious cities takes effect; CM says historic step towards de-addiction
Bhopal (PTI): A ban on liquor in 19 religious cities and areas under select gram panchayats in Madhya Pradesh, including Ujjain, Omkareshwar, Maheshwar and Maihar, came into effect on Tuesday. Chief Minister Mohan Yadav described it as a "historic step towards de-addiction".
The CM had announced the liquor ban decision and it was approved by the cabinet on January 24 at its meeting held in Maheshwar town, a place closely associated with legendary medieval-era queen Lokmata Ahilyabai Holkar.
According to the decision, all liquor shops and bars will be closed down in the entire urban limits of Ujjain, Omkareshwar, Maheshwar, Mandleshwar, Orchha, Maihar, Chitrakoot, Datia, Panna, Mandla, Multai, Mandsaur and Amarkantak and in the gram panchayat limits of Salkanpur, Kundalpur, Bandakpur, Barmankalan, Barmankhurd and Linga, an official said.
The BJP government has declared these 19 urban and rural areas as "completely sacred", and imposed a total ban on liquor under their jurisdiction.
Yadav in a statement said the government has taken a "historic step towards de-addiction" and cited "public faith and religious reverence" associated with these cities and rural areas as reasons for the move.
The religious places where the liquor ban takes effect from Tuesday are spread across one municipal corporation, half-a-dozen municipal councils and an equal number of village panchayats.
Among these, Ujjain houses the famous Mahakal Temple dedicated to Lord Shiva, while Amarkantak is the origin of the Narmada river, which is considered the lifeline of the state.
