BENGALURU: The Indian Space Research Organisation on Monday efficiently accomplished the static take a look at of a human-rated stable rocket booster (HS200) for the Gaganyaan programme at Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh.

The HS200 is the human-rated model of the S200 rocket booster of satellite tv for pc launch car GSLV Mk III, popularly generally known as LVM3, the Bengaluru-headquartered area company famous in an announcement.

“The successful completion of this test marks a major milestone for the prestigious human space flight mission of ISRO, the Gaganyaan, as the first stage of the launch vehicle is tested for its performance for the full duration,” it stated.

The occasion was witnessed by ISRO Chairman and Secretary within the Department of Space, S Somanath, and Director of Vikram Sarabhai Space Centre (VSSC) S Unnikrishnan Nair together with different ISRO scientists.

The design and growth of the HS200 booster have been accomplished at VSSC, Thiruvananthapuram and propellant casting was accomplished at SDSC, Sriharikota.

The S200 motor, which is the primary stage of the LVM3 launch car meant for launching a 4,000 kg class satellite tv for pc to the geosynchronous switch orbit, was configured as a strap-on rocket booster.

Based on the profitable launch pedigree of this launch car together with the Chandrayaan mission, the LVM3 has been recognized because the launcher for the Gaganyaan mission.

For the manned area mission, LVM3 launch car underwent enhancements stipulated by the necessities of human ranking, it was said.

Accordingly, a number of design enhancements geared toward growing the protection and reliability of assorted techniques have been applied within the S200 booster like all different techniques.

These embrace extra security options for motor case joints, sturdy insulation and ignition techniques.

The management system used on this booster employs one of many world’s strongest electro-mechanical actuators with a number of redundancies and security options, ISRO stated.

The system is indigenously designed and developed by ISRO in participation with numerous industries unfold throughout the nation.

“Despite the restrictions imposed by the pandemic, ISRO could complete the entire design, development, realisation and testing process within a short span of two years,” the assertion stated.

The HS200 booster loaded with 203 tonnes of stable propellant was examined for a period of 135 seconds.

The 20-metre lengthy and three.2 m diameter booster is the world’s second-largest operational booster with stable propellant, it stated.

During the take a look at, about 700 parameters have been monitored and the efficiency of all of the techniques was regular, the area company additional stated.

“With the successful completion of this test, ISRO marches one more step closer to Gaganyaan Programme,” it stated.

Out of the three propulsion phases of LVM3, the human-rated variations of the second-stage generally known as L110-G loaded with liquid propellant and the third stage C25-G with cryogenic propellant are within the last part of qualification, together with checks with static firing.

“Gaganyaan programme, the most prestigious scientific endeavour of India, is steadily progressing towards its final goal of taking an Indian to space and bringing him safely back,” ISRO added.
