ISRO Efficiently Assessments Propulsion Methods on India’s First Human Spaceflight Mission Gaganyaan

ISRO has efficiently carried out two extra exams as a part of plans to additional validate and refine the efficiency of the propulsion system that will be used to launch India’s first human spaceflight mission Gaganyaan. The “scorching exams” on Gaganyaan Service Module Propulsion System (SMPS) have been performed on the ISRO Propulsion Complicated, Mahendragiri, in Tamil Nadu on Wednesday.

The Gaganyaan challenge envisages demonstration of human spaceflight functionality by launching a crew of three members to an orbit of 400km for a 3 days mission and convey them again safely to earth, by touchdown in Indian sea waters, based on ISRO.

“These exams will additional validate and refine the efficiency of the propulsion system, guaranteeing its readiness for the upcoming Gaganyaan mission,” it stated.

“These exams (carried out on July 26) marked the second and third scorching exams within the Service Module – System Demonstration mannequin (SM-SDM) part 2 check sequence. The primary scorching check was performed on July 19, 2023,” the Bengaluru-headquartered nationwide area company stated in an announcement.

ISRO stated three extra scorching exams are scheduled, to exhibit de-boosting necessities and off-nominal mission situations.

The SMPS is designed and developed by the Liquid Propulsion System Centre positioned at Bengaluru and Valiamala, Thiruvananthapuram.

Throughout the exams on Wednesday, the thrusters have been operated in each steady and pulse mode, in sync with the mission profile.

The preliminary scorching check which lasted for 723.6 seconds centered on demonstrating Orbital Module injection and the calibration burn of 100 Newton thrusters and Liquid Apogee Motor (LAM) engines.

“The calibration burn was important to determine and isolate any non-operational engines. The LAM engines and response management system (RCS) Thrusters carried out as anticipated,” the assertion stated.

“The latter scorching check, with a period of 350 seconds, aimed to exhibit the circularisation of the Orbital Module to realize the ultimate orbit. Throughout this check, the LAM engines operated in steady mode, whereas the RCS Thrusters fired in pulse mode,” it added.
