Where are the fuel and oxidiser lines? Gas generator and turbopumps? Very misleading to call it a "cryogenic engine" when only combustion chamber is displayed.

I thought it is pressure fed. I could be wrong(mostly am), but I think this is for their second generation lander. If so, it does not need to be super powerful, and it will be self pressurized.

never mind I confused myself about which engine this was. like I said, 'mostly wrong'

Skyroot and ISRO have signed an agreement to allow Skyroot to access ISRO's facilities and technical expertise. Skyroot also says they plan to launch their first rocket by the end of 2021. It's not specified if that would be their Vikram-1, an orbital vehicle with a payload capacity slightly higher than that of Electron, but Skyroot doesn't seem to be on the suborbital-to-orbital path, so I don't know if they have anything smaller than Vikram-1 to launch.

NEW YORK, July 6, 2021 /PRNewswire/ -- Skyroot Aerospace, India's leading private space launch company, is set to take the global stage with help from its recent $11 million Series A capital raise. The funding will be used to acquire new talent and complete the development of its Vikram-1 launch vehicle. The company aims to reach orbit, with 90 percent less development cost than its competitors, as early as next year.

Launching "as early as next year" is a bit of a push from this article published in February, which said they planned to launch "by the end of this year [2021]." Sure, five months passed (the new article PM3 posted is from July), so slippage is normal, but this feels like more than 1:1 slippage.

Skyroot test fires India's first privately built cryogenic rocket engine [dated Nov. 25]

Quote
Bengaluru: Skyroot Aerospace, a Hyderabad-based space technology startup, has test fired India’s first privately developed fully cryogenic rocket engine, successfully demonstrating the technology that will power the upper stages of its upcoming Vikram-2 orbital launch vehicle.

The rocket engine, named Dhawan-1 in honour of Indian rocket scientist Satish Dhawan, has been developed using 3D printing technology and is fuelled by liquefied natural gas and liquid oxygen—a high-performance, low-cost and clean rocket fuel, the company said.

“This is a completely ‘Made-in-India' cryogenic engine developed using 3D printing with a superalloy, reducing manufacturing time by more than 95%,” said Pawan Kumar Chandana, cofounder and chief executive at Skyroot Aerospace. “This test makes us one of the very few companies in the world to have successfully demonstrated this technology.”

<snip>

With this milestone, Skyroot has demonstrated all the three propulsion technologies that will be used in its first series of small satellite launch vehicles, it said. In December last year, the company successfully test fired its Kalam-5 solid propulsion rocket engine, a larger version of which will be used to power the lower stages of its Vikram rocket.

“The complex engine start and shut-off transients (were) perfectly smooth, combustion was very stable, and pressure was rock steady. This is a phenomenal achievement by our team and we’ve mastered handling two cryogenic fuels,” said Padma Shri awardee V Gnanagandhi, who heads the cryogenic propulsion team at Skyroot.

<snip>

In September this year, the company became the first space tech firm to formally enter into an agreement with the Indian Space Research Organisation (ISRO) to utilise its facilities and get access to its expertise for testing and qualification of its small satellite launch vehicles, the first launch of which is scheduled for 2022.

 What would be a realistic time frame for Skyroot to convert their impressive ground testing achievements of rocket stages, into an actual workable, successful satellite launch vehicle?

5-10 years

  That's interesting , because these companies speak of 1 year to launch their vehicles. One of them( Skyroot or Agnikul) were even scheduling launches by the end of 2021!  What were they referring to, just a test with a small experimental payload?  Even if that were successful within a year, it would be impressive!

With this, Skyroot, which is the first startup with whom ISRO signed an MoU for sharing facilities and expertise, has so far raised $17 million, the largest by an Indian space startup yet, it said.

Hyderabad (Telangana) [India], February 15 (ANI/NewsVoir): Hyderabad-based space startup “Navars Edutech” envisages launching 100 student-developed satellites constellation with Skyroot Aerospace as a launch partner in the next five years.

This partnership enables Navars Edutech to become India’s first Space Education startup for K12 students to design and launch satellites to space, using an indigenously developed private launch vehicle of Skyroot Aerospace. With a mission to take the first set of Satellites to LEO (Low Earth Orbit) with Skyroot’s maiden launch Vikram-I in December-2022, students will develop the intended satellite constellations for astronomical observations. Navars will lead this exciting EdTech transformation for the first time in the country at the school level.

Static test of Kalam-100, stage 3 engine for Vikram-1 launcher.

Quote
Named after Indian scientist and former President Dr. APJ Abdul Kalam, ‘Kalam-100’, the third stage of our Orbital vehicle Vikram-1 completes successful static test. The stage produces a peak vacuum thrust of 100 kN (or ~10Tons), and has a burn time of 108 sec.

State-of-the-art technologies like carbon composite case, high propellant volumetric loading upto 94%, lighter EPDM based thermal protection system, and submerged nozzle have been validated through the successful static test proving very high reliability of the stage, with no moving parts and high level of automation in manufacturing.

A good match of test results with our design predictions has been obtained. This is yet the largest rocket stage ever designed, manufactured, and tested completely in the Indian private sector.
Test Date: 5th May, 2022
Test location: Solar Industries, Nagpur.
