- The rocket was launched through a mobile launcher from Thiruvidandhai, Chennai. The rocket has been jointly built by Tamil Nadu based startup Space Zone India and Martin Group.
About RHUMI-1
- It is known for its innovative hybrid propulsion system, which combines the advantages of both liquid and solid fuels.
- The hybrid design of RHUMI – 1, which uses solid propellant and liquid oxidizer, reduces the risk of accidental explosion by only mixing these components during combustion.
- Through hybrid rocket RHUMI 1, 3 Cube satellites and 50 PICO satellites were sent into suborbital trajectory. These satellites will collect data for research related to global warming and climate change.
- The RHUMI 1 rocket is equipped with a generic fuel based hybrid motor and an electrically triggered parachute system. The rocket has been specially designed focusing on flexibility and reusability.
- Three cube satellites sent into space with the rocket will be able to review atmospheric conditions such as cosmic radiation, UV radiation and air quality.
Rocket components capable of landing safely in the sea
- Hybrid rocket RHUMI 1 has eco-friendly and cost effective mechanism.
- It has a CO2 trigger parachute system. With its help, the rocket components can land safely back on the sea.
- This will reduce the cost of space launch.
- Rocket components can be easily recovered. The air frame of the rocket is made of carbon fiber and glass fiber.
