Q. Which space organization has designed and developed the world's largest solid propellant mixer for rocket motors?
Answer: Indian Space Research Organisation (ISRO)
Notes: ISRO has developed a 10-tonne vertical propellant mixer for solid motors, making India’s space sector more self-reliant. It is the world’s largest solid propellant mixing equipment, designed by Satish Dhawan Space Centre with Central Manufacturing Technology Institute. The mixer enhances productivity, quality, and efficiency in heavy solid motor production. It weighs around 150 tonnes and measures 5.4m in length, 3.3m in breadth, and 8.7m in height. It features hydrostatic-driven agitators and remote operation via PLC-based SCADA control. Solid propulsion is crucial for India’s space transportation, requiring precise mixing of hazardous ingredients.
