Isro’s bid to improve launch vehicle LVM3’s weight-lifting capacity has crossed a significant milestone with the Liquid Propulsion Systems Centre (LPSC) qualifying a critical component that powers the cryogenic upper stage (CUS) for Gaganyaan with a higher thrust.“On September 22, the CE20 E13 engine underwent a successful hot test at the Isro Propulsion Complex (IPRC), Mahendragiri, securing qualification for Gaganyaan and a 22-tonne thrust capability,” Isro said.
