The Indian Space Research Organisation (ISRO) has successfully conducted the flight acceptance hot test of the CE-20 cryogenic engine that will power the Cryogenic Upper Stage of the LVM3 launch vehicle for the Chandrayaan. The space agency said the test was successfully conducted on February 24, at the ISRO Propulsion Complex, Mahendragiri in Tamil Nadu.
“The hot test was carried out for a planned duration of 25 seconds at the High Altitude Test Facility. All the propulsion parameters during the test were found satisfactory and closely matched with predictions. The cryogenic engine will be further integrated with the propellant tanks, stage structures and associated fluid lines to realise the fully integrated flight cryogenic stage,” ISRO said.
This flight acceptance hot test of the CE-20 cryogenic engine comes just one day after the Chandrayaan-3 lander passed the critical EMI-EMC (Electromagnetic Interference/ Electromagnetic Compatibility) test at Bengaluru’s U.R. Rao Satellite Centre.
The Propulsion, Lander module and Rover modules comprise the Chandrayaan-3 interplanetary mission. Because of the mission’s complexity, radio-frequency (RF) communication links must be established between the modules.
Chandrayaan-3 is India’s third moon mission and a follow-up mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface. The mission is scheduled to launch later this year by Launch Vehicle Mark 3 (LMV3) from the Satish Dhawan Space Centre in Sriharikota.
