INDIA: Indian Space Research Organisation (ISRO) is the country’s national space agency, and Bangalore serves as its administrative centre. For duties including space-based applications, space exploration, and the development of related technology, ISRO serves as India’s primary organization.
Since its founding in 1963, the organization has assisted in a range of fields, including emergency management, telemedicine, navigation, and reconnaissance missions.
India’s socio-economic and industrial development has also benefited significantly from its programmes and spin-off innovations. The Department of Space (DOS), which is also directly supervised by the Prime Minister of India, is run by the Chairman of ISRO.
The organization may use a hybrid motor that was successfully tested to design a new propulsion system for the upcoming launch vehicles.
According to the Bengaluru-based space agency, the 30 kN hybrid motor tested on Tuesday at the ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu is stackable and scalable.
The ISRO Liquid Propulsion Systems Center (LPSC) assisted with the test. The motor’s fuel was hydroxyl-terminated polybutadiene (HTPB), while the oxidizer was liquid oxygen (LOX). In contrast to solid-solid or liquid-liquid combinations, a hybrid motor uses solid fuel and a liquid oxidizer, it was said.
“The 30 kN hybrid motor test conducted today (Tuesday) demonstrated ignition and sustained combustion for the predicted 15 seconds. The motor performance was sufficient”, the ISRO said in a statement.
The oxidizer in standard HTPB-based solid propellant rocket motors is ammonium perchlorate.
The oxidizer in standard HTPB-based solid propellant rocket motors is ammonium perchlorate. Oxidizers supply the oxygen required for combustion in rocket engines.
It was explained that throttling was made simpler by using liquids, and restarting was made feasible by controlling the flow rate of LOX. Although HTPB and LOX both promote environmental sustainability, ISRO claims that LOX is safer to handle. It stated that the hybrid motor tested on Tuesday was stackable and scalable, opening the door for a new propulsion technology for upcoming launch vehicles.
According to the VSSC, the technology demonstration paves the way for hybrid propulsion-based sounding rockets and provides an interesting setting for research, including vertical landing for spent-stage recovery.
ISRO will test the technology on a sounding rocket launch in the future as part of its effort to improve the technology.
