ISRO successfully commences testing of semi-cryogenic engine
Bengaluru (PTI): The Indian Space Research Organisation has sucessfully commenced testing of its semi-cryogenic engines that would power future launch vehicles.
The very first integrated test on an intermediate configuration of the 2000 kN (Kilonewton)
semi-cryogenic engine carried out at the newly-commissioned Semicryogenic Integrated Engine & Stage Test facility at ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu on Wednesday was successful, the Bengaluru-headquartered national space agency said.
The test is a step towards developing a 2000 kN thrust engine, which works on Liquid Oxygen (LOX)-Kerosene propellant combination, for future launch vehicles, an ISRO statement said.
The intermediate configuration, designated as Power Head Test Article (PHTA), comprises all the engine systems except the thrust chamber.
It was the first of a series of tests planned to validate the design of the propellant feed system, including the low-pressure and high-pressure turbo-pumps, the gas generator, and control components.
The Liquid Propulsion Systems Centre (LPSC) of ISRO has undertaken the design & development of a semi-cryogenic engine with 2000 kN thrust with Indian industry participation, and it will power the booster stages of future launch vehicles.
Wednesday's test is a major milestone before integrating the complete engine and its qualification, ISRO said.
"This test demonstrated the complex chill-down operations spanning about 15 hours duration that was conducted successfully, meeting all the required conditions for engine start. After the chill down of the LOX circuit, the feed circuit of kerosene was filled, and LOX was admitted into the gas generator by opening the injection valve. Successful performance of the test article helps derive the sequence of operations for further tests," it said.
The new facility at IPRC with a state-of-the-art Programmable Logic Controllers-based control system and data acquisition system, is capable of testing semi-cryogenic engines up to 2600 kN thrust and will support the subsequent testing and qualification of the fully integrated semi-cryogenic engine and stage, ISRO said.
This test, the space agency said, has demonstrated the successful performance of the test facility and PHTA in the first attempt itself.
According to ISRO, the Semi Cryogenic Propulsion System Project envisages the design and development of a 2000 kN semi-cryogenic engine and 'SC120 stage' that will enable the development of a heavy-lift capability for future Indian space transportation systems.

Inappropriate for MLAs seeking free IPL tickets, says D.K. Suresh
Bengaluru: Bengaluru Milk Union Ltd President D.K. Suresh on Monday said it is inappropriate for MLAs to seek free IPL tickets, adding that those interested in watching matches should pay for them personally.
Speaking to reporters near his residence in Sadashivanagar, he said, “IPL is a commercial tournament and does not represent the country. It is not right for public representatives to focus too much on such matters.”
Referring to the recent controversy during the RCB celebrations, he said, “let us find out who benefited the most from the statements made during the incident.” He also pointed out that BJP MLAs had received IPL tickets as well.
Responding to discussions about relocating the Chinnaswamy Stadium, Suresh said the government has already approved the construction of a new stadium at a location he had proposed.
“I had suggested building a stadium in Surya City and submitted a proposal for it. Bengaluru needs four stadiums in four directions to cater to its growing population and encourage youth participation in sports,” he said.
He noted that apart from Kanteerava Stadium, KSCA, and the Football Stadium, there are limited facilities in the city.
“When I was a Lok Sabha member, I had proposed allocating 100 acres in my constituency at Surya City. The land was later earmarked and the plan approved,” he added.
Suresh said he has discussed the project with Minister Zameer Ahmed Khan, Rajiv Gandhi Housing Corporation Chairman Shivalingegowda, and Anekal MLA Shivanna.
“The Cabinet has now approved the project, and a stadium will be developed on around 50–60 acres,” he said.
He further added that he has requested the Deputy Chief Minister to build another stadium at Shivarama Karanth Layout through the BDA, where 40 acres have been allocated. Plans are also being discussed to develop a well-equipped stadium in Bidadi.
Commending state government's recent bilingual policy move, Suresh said forcing children to learn three languages could affect their comprehension.
“It is a good decision to make two languages compulsory. Learning a third language should be left to the choice of students and parents,” he said.
Responding to criticism from BJP leaders, he said their tendency is to oppose every decision of the government.
“To please their central leadership, they take a pro-Hindi stance. Instead, they should advocate for the adoption of Kannada in all states,” he said.
When asked about the earlier three-language policy under Congress, he said, “the situation is different now. Today, the focus should be on quality learning. Kannada should remain the primary language, while students and parents can choose an additional language.”
