The nation's national [space agency](https://answers.mindstick.com/qa/32252/cryogenic-engine-for-upper-stage-of-gslv-mk-iii-was-successfully-tested-by-which-space-agency) located here revealed that the locally developed **CE20 cryogenic engine for [Launch Vehicle](https://answers.mindstick.com/qa/97969/kslv-ii-nuri-rocket-is-the-first-domestically-produced-space-launch-vehicle-of-which-country) Mark 3 (LVM3) passed a successful hot test on November 9** with an improved thrust level of 21.8 tonnes. With extra propellant loading, the LVM3's payload [capabilities](https://www.mindstick.com/interview/490/explain-the-concepts-and-capabilities-of-assembly-in-dot-net) will increase to 450 kg, according to **ISRO**. The addition of a Thrust Control Valve (TCV) for thrust control was the main modification made to this test article in comparison to earlier engines, the space agency added. With extra propellant loading, the LVM3's payload capabilities will increase to 450 kg, according to ISRO. **The addition of a Thrust Control Valve (TCV) for thrust control was the main [improvement](https://answers.mindstick.com/qa/32074/which-state-introduces-land-improvement-schemes-act-bill-to-empower-farmers-in-state)** made to this test component in comparison to earlier engines, the space agency noted. 'In addition, **3D printed exhaust casings for the LOX and LH2 turbines** were initially incorporated into the engine. The engine ran at a thrust level of about 20 tonnes for the first 40 seconds of the test, and then the thrust control valve was moved to increase the thrust level to 21.8 tonnes 'The declaration said. Satellites weighing up to four tonnes can be launched into geosynchronous transfer orbit using the three-stage LVM3 rocket, which has a cryogenic core stage, a liquid propellant core stage, and two solid motor strap-on stages. According to a statement released by the [Indian Space](https://yourviews.mindstick.com/view/87410/indian-space-station-chandrayaan-4-plans-ready-for-govt-approval-isro) [Research Organisation](https://answers.mindstick.com/qa/38477/name-the-navigational-satellite-launched-by-the-indian-space-research-organisation-isro-from-sriharikota-spaceport-in-andhra-pradesh) on Wednesday, the **Reusable Launch Vehicle - [Technology](https://www.mindstick.com/articles/13005/the-functional-aspects-of-laser-technology) Demonstrator (RLV-TD) is scheduled to conduct its first runway landing experiment (RLV-LEX)** on Thursday from an aeronautical test range in the Chitradurga district of Karnataka. The [organization](https://answers.mindstick.com/qa/100623/what-is-the-role-of-the-world-health-organization-in-global-health)'s chairman, S. Somanath, said they were keeping an eye on the weather. According to **ISRO** officials, the RLV wing body will be flown by helicopter to a height of three to five kilometres before being dropped at a distance of about four to five kilometre with a horizontal velocity. --- Original Source: https://www.mindstick.com/news/2368/isro-s-heaviest-lvm3-rocket-payload-capability-increases-by-up-to-450kg Copyright © MindStick Software Pvt.
