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.

Two arrested in K'taka for assaulting minors, uploading CSAM content
Bengaluru (PTI): Two men were arrested for allegedly sexually assaulting two minor girls, recording the acts on mobile phones and uploading the videos online as child sexual abuse material, police said on Thursday.
The accused have been identified as Kiran Kumar (29), hailing from Chitradurga district, and Aditya M K (20), hailing from Shivamogga district, they said.
A probe was initiated after information was received from the NCRP portal regarding a suspected instance of creation of Child Sexual Abuse Material (CSAM) for online dissemination, police said.
Accordingly, a case was registered at Kaggalipura Police Station under relevant sections of the IT Act on May 10, they added.
Investigation revealed that two minor girl victims were exploited and videos were created and uploaded to the internet. The child victims have subsequently recorded their statements as per procedure and further necessary legal steps have been taken, Pronab Mohanty Director General of Police, Cyber Command, said in a statement.
Based on the statements of the victims, the accused persons, who allegedly assaulted the minors, recorded the acts on mobile phones and uploaded the videos online, were arrested, he said.
Following the probe, sections 65(2) (rape) and 70 (gangrape) of the Bharatiya Nyaya Sanhita, along with relevant sections of the POCSO Act, have been added to the FIR, police said.
Officials collected relevant information and on May 12, arrested the accused persons and seized three mobile phones belonging to them, in which the videos had allegedly been recorded, he said.
The accused were later produced before the court and taken into police custody for further investigation, he added.
According to him, in CSAM cases, police usually apprehend offenders who have downloaded such content or have kept them in their possession after obtaining them from elsewhere, usually the internet.
"The present case is one of the very few instances where content creators and uploaders have been apprehended," Mohanty added.
