ISRO Efficiently Completes Engine Check For Human Spaceflight Programme

The Vikas engine makes use of storable propellants in a pump-fed fuel generator cycle.


ISRO on Thursday mentioned it had accomplished the ultimate long-duration sizzling take a look at of human-rated L110-G Vikas engine for the deliberate qualification length of 240 seconds, marking a serious milestone within the journey in the direction of the launch of the Gaganyaan human spaceflight programme.

The take a look at was carried out on the ISRO Propulsion Complicated (IPRC), Mahendragiri, Tamil Nadu.

“With this take a look at all of the deliberate qualification checks of the engine are accomplished efficiently,” ISRO (Indian Area Analysis Organisation), the Bengaluru-headquartered nationwide house company mentioned in an announcement.

The air-lit liquid core stage of the human-rated launch automobile (LVM3-G) makes use of two L110-G Vikas engines in clustered configuration. The design and realisation of L110 stage for Gaganyaan was carried out on the Liquid Propulsion Programs Centre (LPSC), and meeting and integration and testing had been completed at IPRC. The Engine Gimbal Management system was developed by Vikram Sarabhai Area Centre (VSSC).

The human-rated Vikas engine has increased structural margins for sub-systems, improved meeting course of and extra measurements for well being monitoring. The event sizzling checks it was subjected to had been carried out in a step-by-step method on the Principal Check Stand, IPRC, the discharge mentioned.

9 engines had undergone 14 sizzling checks with a cumulative length of 1,215 seconds, together with 4 long-duration checks of 240 seconds every.

Drawn from the intensive legacy and expertise of liquid rocket engine growth, the take a look at marketing campaign envelopes excessive working durations, off-nominal combination ratios and thrust degree situations as in comparison with flight working situations, ISRO mentioned.


4 units of {hardware} used for this take a look at programme had been fabricated at varied Indian industries.

Electro-mechanical Gimbal actuators and Command System module for engine pilot stress management, with a number of redundancies had been additionally certified within the take a look at. ISRO may full the human-rated L110-G Vikas engine qualification inside a brief span of three years, it added
