Detailed explanation-1: -The CE-20 is a cryogenic rocket engine developed by the Liquid Propulsion Systems Centre, a subsidiary of Indian Space Research Organisation. It has been developed to power the upper stage of the LVM 3 . It is the first Indian cryogenic engine to feature a gas-generator cycle.

Detailed explanation-2: -The Indian Space Research Organisation (ISRO) has successfully conducted the hot test of CE20 cryogenic engine, which has been indigenously developed for LVM3, previously called the GSLV-Mk3. According to the space agency, CE20 cryogenic engine is indigenously developed for LVM3.

Detailed explanation-3: -ISRO’s Cryogenic Upper Stage Project (CUSP) envisaged the design and development of the indigenous Cryogenic Upper Stage to replace the stage procured from Russia and used in GSLV flights. The main engine and two smaller steering engines of CUS together develop a nominal thrust of 73.55 kN in vacuum.

Detailed explanation-4: -The Russians had designed these engines in the 1960s but not flown them, probably because they were still not flight ready. Moreover, they used a technology-called stage combustion-that was efficient but difficult. It made the engine a bit heavy but gave the highest efficiencies for a specific amount of propellant.

Detailed explanation-5: -Indian Space Research Organisation’s Propulsion Research Complex (IPRC) at Mahendragiri in the district has successfully conducted a 70-second-long ‘Pressure Chamber Test’ of the cryogenic engine to be used in ‘Gaganyaan’ programme.
