Context: ISRO successfully developed a 10-tonne vertical planetary mixer, the largest solid propellant mixing equipment globally, in collaboration with CMTI, Bengaluru.
About Vertical Planetary Mixer:
- What is a Vertical Planetary Mixer?
-
- A high-capacity mixing system designed for processing solid propellants used in rocket motors.
- Ensures precise blending of hazardous and sensitive ingredients, crucial for rocket motor efficiency.
- Developed by:
-
- Satish Dhawan Space Centre (SDSC), ISRO, in collaboration with Central Manufacturing Technology Institute (CMTI), Bengaluru.
- Part of the ‘Atmanirbhar Bharat’ initiative to enhance indigenous space capabilities.
- How It Works?
-
- Uses multiple hydrostatic-driven agitators for uniform mixing of solid propellant components.
- Operated remotely via a PLC-based control system with SCADA stations for precision and safety.
- SCADA (Supervisory Control and Data Acquisition) stations are control systems that monitor and manage physical processes in real time.
- Key Features:
- Largest Capacity: Mixes 10 tonnes of propellant in a single batch.
- High Precision: Ensures uniform composition for better rocket performance.
- Safety & Reliability: Designed for hazardous materials handling with strict quality control.
- Automation: Remotely controlled system enhances safety and efficiency.
- Massive Structure: Weighs 150 tonnes; dimensions: 5.4m (L) × 3.3m (B) × 8.7m (H).
- Significance of the Mixer:
-
- Enhances Rocket Motor Production: Increases productivity, throughput, and quality in solid propulsion systems.
- Boosts Indigenous Capability: Reduces dependency on foreign technology, aligning with India’s self-reliance goals.
- Supports Future Space Missions: Strengthens ISRO’s launch vehicle programs, including PSLV, GSLV, and future heavy-lift rockets.
- Collaboration with Academia & Industry: Promotes innovation in advanced space manufacturing.
