What is RHUMI 1. All You Need to Know About India's First Hybrid Reusable Rocket

Chennai: Rhumi-1, India's first hybrid reusable rocket, was launched from the East Coast Road coastline at Thiruvidandhai in Chennai on Saturday using a mobile launcher. Developed by Tamil Nadu-based start-up Space Zone India in collaboration with the Martin Group, the rocket carries three CubeSats and 50 PICO satellites on a suborbital trajectory.

Reusable and Cost-Effective

Anand Megalingam, CEO of Space Zone India, stated that Rhumi-1 aims to reduce costs while gathering valuable data on radiation levels, vibration intensity, temperature, and more. 

"Our goal is to develop a reusable rocket to lower expenses. We’ve opted for a hybrid propulsion system using Nitrous Oxide and solid-state Wax fuel, with combustion occurring in a single chamber," Megalingam said. 

He further added that this hybrid approach is more cost-effective compared to traditional liquid propulsion systems, allowing them to build the propulsion system at one-third of the cost.

Inspiration Behind the Name

The rocket's name, Rhumi-1, is a tribute to Megalingam's son, Rhumendran. “Since his birth, I’ve only been able to spend a day with him due to my commitments to the rocket’s development. Naming the rocket Rhumi-1 is my way of being with him,” Megalingam shared.

Support and Innovations

Megalingam also acknowledged the support of Prime Minister Narendra Modi and Tamil Nadu Chief Minister MK Stalin, stating that both the central and state governments provided prompt approval for the launch.

CO2-Triggered Parachute System

The rocket features a CO2-triggered parachute system, an eco-friendly and cost-effective solution designed to ensure the safe recovery of rocket components post-launch. 

Besides its primary focus on space exploration, Rhumi-1 has potential applications in agriculture, environmental monitoring, and disaster management.
