ISRO test fires hybrid motor to power future rockets

Indian Space Research Organisation (ISRO) successfully tested a hybrid motor that would power its future rockets. The test was done at ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu supported by Liquid Propulsion Systems Centre (LPSC) on Tuesday.

The motor used Hydroxyl-terminated polybutadiene (HTPB) as fuel and liquid oxygen (LOX) as the oxidizer. Unlike solid-solid or liquid-liquid combinations, a hybrid motor uses solid fuel and liquid oxidizer.
