Bengaluru: In what it describes as a big development, the Indian Area Analysis Organisation (Isro) Tuesday mentioned it has efficiently developed a light-weight carbon-carbon (C-C) nozzle for rocket engines, marking a breakthrough in rocket engine know-how.
This innovation, achieved by the Vikram Sarabhai Area Centre (VSSC), guarantees to boost the very important parameters of rocket engines, together with thrust ranges, particular impulse, and thrust-to-weight ratios, thereby boosting the payload capability of launch autos.
VSSC has leveraged superior supplies like carbon-carbon (C-C) composites to create a nozzle divergent that gives distinctive properties, Isro mentioned.
“…Utilising processes similar to carbonisation of inexperienced composites, chemical vapour infiltration, and high-temperature remedy, VSSC has produced a nozzle with low density, excessive particular energy, and wonderful stiffness, able to retaining mechanical properties even at elevated temperatures,” Isro mentioned.
A key function of the C-C nozzle is its particular anti-oxidation coating of silicon carbide, which extends its operational limits in oxidising environments. This innovation not solely reduces thermally induced stresses but in addition enhances corrosion resistance, permitting for prolonged operational temperature limits in hostile environments.
The potential affect of this growth is important, notably for Isro’s workhorse launcher, the Polar Satellite tv for pc Launch Automobile (PSLV).
The PS4, the fourth stage of the PSLV, at present employs twin engines with nozzles produced from Columbium alloy. Nevertheless, by changing these metallic divergent nozzles with C-C counterparts, a mass discount of roughly 67% will be achieved.
This substitution is projected to extend the payload functionality of the PSLV by 15kg, a notable enhancement for house missions.
The profitable testing of the C-C nozzle divergent marked a significant milestone for Isro.
“On March 19, a 60-second scorching take a look at was performed on the high-altitude take a look at (HAT) facility in Isro Propulsion Advanced (IPRC), Mahendragiri, confirming the system’s efficiency and {hardware} integrity. Subsequent checks, together with a 200-second scorching take a look at on April 2, 2024, additional validated the nozzle’s capabilities, with temperatures reaching 1216K, matching predictions,” Isro added.
The collaborative effort concerned the Liquid Propulsion Programs Centre (LPSC) at Valiamala, which designed and configured the take a look at, and IPRC, Mahendragiri, which performed the instrumentation and execution of the checks at their HAT facility.
