Indian Space Research Organisation (ISRO) has accomplished two key tests for Gaganyaan — the Human Space Flight Programme.
The area company mentioned that the ultimate long-duration scorching take a look at of human-rated L110-G Vikas engine was efficiently completed for the deliberate qualification length of 240 seconds on April 6 at ISRO Propulsion Complex (IPRC), Mahendragiri.
According to the area company, the profitable completion of this take a look at marks a significant milestone within the human area flight programme, Gaganyaan, of ISRO. The air-lit liquid core stage of human-rated launch automobile (LVM3-G) makes use of two L110-G Vikas engines in clustered configuration. With this take a look at, all of the deliberate qualification tests of the engine have been accomplished efficiently.
The Vikas engine makes use of storable propellants in a pump-fed fuel generator cycle. Human rated Vikas engine has larger structural margins for sub-systems, improved meeting course of and extra measurements for well being monitoring. Human rated Vikas engine growth scorching tests had been performed in a step-by-step method at Principal Test Stand, IPRC. Nine engines had undergone 14 scorching tests with a cumulative length of 1215 seconds, together with 4 long-duration tests of 240 seconds every.
ISRO added that it may full the human-rated L110-G Vikas engine qualification inside a comparatively brief span of three years.
Crew module propulsion system take a look at
Gaganyaan has received a bipropellant-based propulsion system for offering 3-axis management (Pitch, Yaw & Roll) to crew module following service module separation throughout re-entry, i.e. from an altitude of 170 km to 7 km until deployment of the parachute-based deceleration system.
It additionally gives altitude management within the ascent part abort, if any, from 3 km to 70 km.
On April 5, the new take a look at of the crew module propulsion system for demonstrating nominal re-entry for the length of 650 seconds was efficiently performed at ISRO Propulsion Complex, Mahendragiri. Prior to this, a sequence of tests had been carried out with six thrusters.
Completing this take a look at is a significant step in qualifying the Crew Module Propulsion System for the Gaganyaan programme.
