What is RHUMI-1?

About RHUMI-1:

• It is India’s first reusable hybrid rocket.
• It was developed by the Tamil Nadu-based startup Space Zone India in collaboration with Martin Group.
• It stands out for its innovative hybrid propulsion system, combining the advantages of both liquid and solid fuels. 
• Rhumi 1’s hybrid design, which uses solid propellant and liquid oxidizer, reduces the risk of accidental detonation by combining these components only during combustion.

This technology promises improved efficiency and reduced operational costs.

• The rocket also boasts a CO2-triggered parachute system, an eco-friendly and cost-effective mechanism that ensures the safe recovery of rocket components after launch.
• The RHUMI Rocket is completely free of fireworks and uses no TNT.
• About the Launch:
  • Rhumi 1 was launched into space from the East Coast Road Beach in Thiruvidandhai in Chennai.
  • The rocket, carrying 3 Cube Satellites and 50 PICO Satellites, was launched into a suborbital trajectory using India’s first hydraulic mobile launch system, enabling flexible and adaptable launch operations from various locations at different angles between 0 to 120 degrees.
  • The Cube Satellites are tasked with monitoring and collecting data on atmospheric conditions, including cosmic radiation intensity, UV radiation intensity, and air quality.
  • Pico Satellites will focus on analyzing environmental factors such as vibrations, accelerometer readings, altitude, ozone levels, and toxic substances, providing insights into atmospheric dynamics.

Q1: What are oxidizers?

Oxidizers are solids, liquids, or gases that react readily with most organic material or reducing agents with no energy input. Oxidizers are a severe fire hazard. They are not necessarily combustible, but they can intensify combustion and increase the flammable range for chemicals so they ignite more readily.
