Science and Technology

ISRO has developed lightweight Carbon-Carbon (C-C) nozzle for rocket engines. This innovationaccomplished by Vikram Sarabhai Space Centre (VSSC) promises to enhance the vital parameters of rocket engines, including thrust levels, specific impulse, and thrust-to-weight ratios, thereby boosting the payload capacity of launch vehicles. VSSC, continuingits pioneering work in space research, has leveraged advanced materials like Carbon-Carbon (C-C) Composites to create a nozzle divergent that offers exceptional properties. A key feature of the C-C nozzle is its special anti-oxidation coating of Silicon Carbide, which extends its operational limits in oxidizing environments. This substitution is projected to increase the payload capability of the PSLV by 15 kg, a notable enhancement for space missions.


      The PS4, the fourth stage of the PSLV, currently employs twin engines with nozzles made from Columbium alloy.
