The successful operation marks another milestone in India’s space endeavors, highlighting the growing role of private-sector innovations in space exploration. This article delves deeper into Bellatrix Aerospace’s journey, the workings of its green propulsion system, and the future of the technology.

1. Introduction to Bellatrix Aerospace: The Trailblazer in Green Propulsion Technology

Bellatrix Aerospace, a Bengaluru-based start-up, is transforming the space sector with its green propulsion technology. Founded by Yashas Karanam and his team, the company focuses on reducing the environmental impact of space missions while boosting performance with advanced propulsion systems. Its flagship product, the Rudra High-Performance Green Propulsion System, prioritizes eco-friendly, high-efficiency technology.

The start-up provides cutting-edge satellite propulsion solutions, replacing hazardous fuels like hydrazine with non-toxic, high-performing propellants, setting new industry standards.

Bellatrix’s revenue model relies on securing contracts from ISRO and private satellite companies seeking sustainable propulsion solutions. The company has attracted funding from angel investors and venture capital, fueling its growth and innovations.

2. The Rudra Propulsion System: A Technological Marvel

The Rudra High-Performance Green Propulsion System was test-fired aboard the POEM-4 during the PSLV-C60 mission, marking a milestone for Bellatrix Aerospace. Designed to replace traditional propellants with eco-friendly green fuel, the system maintained high performance.

The successful test demonstrated its effectiveness in microgravity, with the Rudra system causing a disturbance of just 1.4 degrees per second in the yaw axis of the POEM-4 platform, achieving 80 degrees of rotation over 60 seconds. This precise control is crucial for steering satellites and space vehicles in orbit.

2.1 How Does the Rudra Propulsion System Work?

The Rudra propulsion system utilizes an advanced, non-toxic propellant developed in-house by Bellatrix Aerospace. The system is designed to operate for a sustained period, with a nominal thrust of 1 Newton and a specific impulse of 220 seconds. This thrust allows for consistent performance in space, crucial for satellite operations such as maintaining orbits and conducting research experiments.

One of the standout features of the Rudra system is its use of 3D-printed components.The 3D-printed propellant tank and thruster reduce weight and cost while ensuring high performance and reliability. Bellatrix also developed thermal and oxidation barrier coatings for efficient performance under extreme space conditions.

2.2 Key Achievements of the Rudra Propulsion System

• As demand for microsatellites and CubeSats rises, the Rudra system is positioning itself as the preferred solution for satellite deorbiting and interplanetary propulsion. This highlights the growing capabilities of the Indian space sector and the country’s increasing self-reliance in space technology.

3. Bellatrix Aerospace’s Contribution to Indian Space Missions

The POEM-4 mission, part of the PSLV-C60 mission, is key for testing new technologies, with the Rudra propulsion system being a highlight. POEM-4 repurposes the PSLV’s spent fourth stage for microgravity experiments, maximizing scientific returns while reducing space debris.

This mission carried 24 experimental payloads from Indian startups, research institutions, and industries, showcasing the collaborative efforts within India’s space sector. IN-SPACe, the Indian National Space Promotion and Authorization Center, actively supports these startups in the growing private space sector.

4. The Future of Green Propulsion Systems: A Leap Toward Sustainable Space Exploration

The success of Bellatrix Aerospace’s Rudra propulsion system marks an important milestone in the development of green propulsion technologies.As sustainability becomes a priority, the Rudra system, replacing toxic propellants like hydrazine, will revolutionize space missions by offering high performance and eco-friendliness.

Bellatrix plans to conduct more tests to refine the system and ensure its scalability for commercial and governmental space missions. As demand for microsatellites and CubeSats rises, the Rudra system is becoming the preferred solution for satellite deorbiting and interplanetary propulsion.
