ISRO successfully tests large human-rated solid rocket booster for Gaganyaan mission



The Indian Space Research Organisation on Friday effectively finished the static take a look at of a human-rated forged 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 release automobile GSLV Mk III, popularly referred to as LVM3, the Bengaluru-headquartered house company famous in a remark.

“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 tournament was once witnessed by way of ISRO Chairman and Secretary within the Department of Space, S Somanath, and Director of Vikram Sarabhai Space Centre (VSSC) S Unnikrishnan Nair along side different ISRO scientists.

The design and construction of the HS200 booster had been finished at VSSC, Thiruvananthapuram and propellant casting was once finished at SDSC, Sriharikota.
The S200 motor, which is the primary level of the LVM3 release automobile meant for launching a 4,000 kg elegance satellite tv for pc to the geosynchronous switch orbit, was once configured as a strap-on rocket booster.

Based at the a hit release pedigree of this release automobile together with the Chandrayaan venture, the LVM3 has been recognized because the launcher for the Gaganyaan venture.

For the manned house venture, LVM3 release automobile underwent enhancements stipulated by way of the necessities of human score, it was once said.
Accordingly, a number of design enhancements aimed toward expanding the security and reliability of quite a lot of programs had been carried out within the S200 booster like several different programs.

These come with further security measures for motor case joints, tough insulation and ignition programs. The keep an eye on device used on this booster employs one of the most international’s maximum tough electro-mechanical actuators with more than one redundancies and security measures, ISRO stated.

The device is indigenously designed and evolved by way of ISRO in participation with quite a lot of industries unfold around 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 remark stated.

The HS200 booster loaded with 203 tonnes of forged propellant was once examined for a length of 135 seconds. The 20-metre lengthy and three.2 m diameter booster is the arena’s second-largest operational booster with forged propellant, it stated.

During the take a look at, about 700 parameters had been monitored and the efficiency of all of the programs was once standard, the distance company additional stated.
“With the successful completion of this test, ISRO marches one more step closer to Gaganyaan Programme,” it stated.

Out of the 3 propulsion levels of LVM3, the human-rated variations of the second-stage referred to as L110-G loaded with liquid propellant and the 3rd level C25-G with cryogenic propellant are within the ultimate section of qualification, together with exams 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.
