The Indian Space Research Organisation (ISRO) said on Wednesday, September 21, 2022, that it has successfully demonstrated a hybrid propulsion system that uses a solid fuel and liquid oxidiser.
The hybrid motor was tested at the ISRO Propulsion Complex (IPRC), Mahendragiri, on Tuesday evening. The hybrid system is more efficient, ''greener'' and safer to handle and paves the way for new propulsion technologies for future missions, the Vikram Sarabhai Space Centre (VSSC) which tested it with support from the Liquid Propulsion Systems Centre (LPSC), said.
In the ground-based test, the flight equivalent 30 kN hybrid motor used Hydroxyl-terminated polybutadiene (HTPB)-based aluminised solid fuel and liquid oxygen (LOX) as the oxidiser. The test was performed for 15 seconds on a 300-mm sounding rocket motor.
