The Indian Space Research Organisation (ISRO) has achieved a major milestone with the profitable growth of a light-weight Carbon-Carbon (C-C) nozzle for rocket engines. This breakthrough in rocket engine know-how, completed by the Vikram Sarabhai Space Centre (VSSC), guarantees to enhance essential parameters similar to thrust ranges, particular impulse, and thrust-to-weight ratios, thereby growing the payload capability of launch autos.
ISRO highlighted that VSSC utilized superior supplies like Carbon-Carbon (C-C) Composites to create the nozzle divergent, which affords distinctive properties. By using processes similar to carbonization of inexperienced composites, chemical vapor infiltration, and high-temperature remedy, VSSC was in a position to produce a nozzle with low density, excessive particular power, and glorious stiffness. Importantly, this nozzle retains its mechanical properties even at elevated temperatures.
A key characteristic of the C-C nozzle is its particular anti-oxidation coating of silicon carbide, which extends its operational limits in oxidizing environments. This coating reduces thermally induced stresses and enhances corrosion resistance, permitting for prolonged operational temperature limits in hostile environments.
The potential impression of this growth is important, particularly for ISRO’s Polar Satellite Launch Vehicle (PSLV), which is a workhorse launcher for numerous area missions. Currently, the fourth stage of the PSLV, referred to as PS4, makes use of twin engines with nozzles comprised of Columbium alloy. However, changing these metallic divergent nozzles with C-C counterparts may result in a mass discount of roughly 67%. This substitution is predicted to extend the payload functionality of the PSLV by 15kg, which is a notable enhancement for area missions.
The profitable testing of the C-C nozzle divergent marked a serious milestone for ISRO. A 60-second sizzling check was performed on March 19 on the High-Altitude Test (HAT) facility within the ISRO Propulsion Complex (IPRC) in Mahendragiri to substantiate the system’s efficiency and {hardware} integrity. Subsequent checks, together with a 200-second sizzling check on April 2, 2024, additional validated the nozzle’s capabilities, with temperatures reaching 1216K, aligning with predictions.
The collaborative effort concerned the Liquid Propulsion Systems Centre (LPSC) at Valiamala, which designed and configured the check, and IPRC, Mahendragiri, which performed the instrumentation and execution of the checks at their HAT facility.
