ISRO successfully tests hybrid propulsion system to aid future technologies
Subject: Science & technology
Context: ISRO had successfully demonstrated a hybrid propulsion system that used a solid fuel and liquid oxidiser.
Concept:
- The test was conducted at ISRO Propulsion Complex (IPRC) at Mahendragiri, in Tamil Nadu supported by Liquid Propulsion Systems Centre (LPSC).
- The motor used liquid oxygen (LOX) as the oxidizer and Hydroxyl-terminated polybutadiene (HTPB) as fuel.
- The 30kN hybrid motor tested at IPRC is scalable and stackable.
Significance
- Using liquids helps in throttling and control over the flow rate of LOX.
- Unlike conventional solid motors, hybrid technology permits restarting and throttling capabilities on the motor.
- Although both HTPB and LOX are green, LOX is safer to handle.
- Unlike solid-solid or liquid-liquid combinations, a hybrid motor utilizes solid fuel and liquid oxidizer.
- The test aims to discover a new propulsion system for the upcoming launch vehicles.
