Hybrid Propulsion System

In News 

• The Indian Space Research Organisation (ISRO) has successfully tested a hybrid propulsion system 

About Hybrid propulsion system

• The 30 kN hybrid motor tested at ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu 
• The test was supported by ISRO’s Liquid Propulsion Systems Centre (LPSC).
• It uses a solid fuel and liquid oxidiser.
  • The motor used Hydroxyl-terminated polybutadiene (HTPB) as fuel and liquid oxygen (LOX) as the oxidiser.
• Significance : It is scalable and stackable, potentially paving the way for a new propulsion system for the forthcoming launch vehicles.
  • The use of liquids facilitates throttling, and the control over the flow rate of LOX enables the re-start capability
  • The hybrid system is more efficient, ”greener” and safer to handle
