Development of Cryogenic Engine for GSLV MkIII: Technological Challenges

Abstract: View the article online for updates and enhancements. Abstract. Cryogenic engine capable of delivering 200 kN thrust is being developed for the first time in the country by ISRO for powering the upper stage of GSLV Mk-III, the next generation launch vehicle of ISRO capable of launching four tonne class satellites to Geosynchronous Transfer Orbit(GTO). Development of this engine started a decade ago when various sub-systems development and testing were taken up. Starting with injector element development, the d… Show more

“…Here, a twin circuit was used to regeneratively cool the chamber in which the throat would be cooled with LH2, while the nozzle would be cooled with LOx, so as to improve chamber life and thereby to increase the engine thrust. In addition to this, during the development stages of ISRO's in-house GSLV Mk 3 project 23,24) , its LOX/LH2 based upper stage engine(CE20) was revolutionary at the time to operate in the gas generator cycle and was sufficient to attain a specific impulse of 443 seconds in a vacuum and operating thrust range between 180 kN to 220 kN, which was indeed a ground-breaking news to the aerospace community. All key elements like as atomization, vaporisation, reaction, mixing, thermal loads, nozzle performance, and engine stability were taken into consideration while designing the CE20's thrust chamber.…”
