Vertical Propellant Mixer

Why in the news?   

           Recently, Indian Space Research Organisation has announced the successful development of a 10-tonne ‘vertical planetary mixer’, the largest of its kind for solid propellants globally.

About Vertical Propellant Mixer:

• It is the largest solid propellant mixing equipment globally.
• It is developed and designed by Satish Dhawan Space Centre in collaboration with Central Manufacturing Technology Institute, a Bengaluru-based research and development organisation under the Ministry of Heavy Industries.
• A propellant mixer is a machine that mixes the ingredients of rocket propellants, specifically fuel and oxidiser, to ensure a uniform and reliable mixture for solid rocket motors.
• The quality of the mixed propellant directly impacts the performance and reliability of the rocket motor.

Key Features of Vertical Propellant Mixer

• It has high-capacity mixing of propellant ingredients in a single batch.
• It has precision and control for quality consistency & performance.
• Safety and Reliability for handling highly hazardous materials.
• World’s Largest: It is of approximately 150 tonnes of weight.
• Advanced Technology: It is equipped with multiple agitators which are hydrostatic driven and will be remotely operated using PLC based control systems with SCADA stations.
