They definitely have expert team with connections that would allow them hire to skilled engineers. Just need finanicial backing.
Indian should be able to support one or two local small LV companies.

I do find this extract from article to be putting horse before cart, given they are only powerpoint rockets at this stage.

:Skyroot claims to be the only company in the world that can carry payloads ranging from 200-700 kg to a low Earth orbit."

Yes, they are talking too big at the moment! But seeing an Indian private sector company actually build and launch its own vehicles will be amazing when it happens.   Incidentally, what happened to Team Indus a.k.a Axiom Labs. They seem to have receded into the background.  They had pretty big plans of building their own rover, and launching it on a non-Indian rocket sometime in 2020.  Hope they are quietly working on that!

I think it relates to the "Space Activities Bill, 2017", a legislative proposal to allow private spaceflight in India. (On the other hand, don't see any confirmation that this bill has been signed into law...)

Skyroot Aerospace seems to be on track. Hope they can get their engine, stage and rocket ready as well.

"Two of the firm’s rocket stages are getting ready for test firing in six months" - so there will be more coming up in the next 6 months.

Skyroot has done a successful test-firing of its upper stage engine:




EDIT: The engine runs on  ̶m̶e̶t̶h̶a̶n̶e̶-̶l̶o̶x̶  hydrazine, and is capable of multiple re-starts.

It's called the Raman engine and is named after Indian Nobel laureate in physics, Dr CV Raman.

1st and 2nd stages are SRBs. Kind of mini Omega. They even plan to use strap on SRBs for additional thrust, like Omega.

Not sure if US engine is pressure or turbo fed. Could start flying with simpler pressure and upgrade to turbo engine later.

Apologies, I need to quickly correct -- people have told me this engine that was just demonstrated runs on hydrazine (UDMH-N2O4), and that it is indeed pressure-fed.
This hypergolic engine will be used as their 4th-stage engine on their initial rocket, called Vikram-1, which is a 4-stage rocket.

They are still developing a methane-lox engine, which will be used for the 3rd-stage engine on their subsequent follow-on rockets, Vikram-2 and Vikram-3.

For a new startup, they have kept the rocket very simple with solids and this upper stage engine is simple as well thus reducing all the risks - good strategy. In the next few months we will hear about their solid motor test firing as well. If any of the indian LV startups will be successful and on time with their deliveries, it will likely be this one. Hope they get their next round of funding.

Out of all indian small sat launcher startups skyroot probably has the best chance of succeeding. They have a very grounded realistic approach of taking advantage of existing solid fuel infrastructure in the country and limiting use of liquid fuel to only upper stage. This cuts cost/complexity and development time significantly, would not be surprised if they beat bellatrix aerospace to orbit at the rate they are moving. Having actual hardware on the test stand to demonstrate to public and potential investors of course also greatly helps their credibility.

Skyroot First Indian Aerospace On Mark To Race With Competitors Blue Origin And SpaceX.

BY BENAK RAAJ SHETTY · AUGUST 19, 2020

History Of Aviation Industry Start And India Role.
Soon after world war II how the aviation industry started. And today how the United States, Russia, France and Britain are ruling the aviation industry. Its always said that “history repeats again and again” it’s correct.

If we go back in time we can see the airline industry started its race soon after world war II. There were many companies which revolutionalized with the speed, Capacity and also use of airline for commercial service.

In today’s world its space exploration time. Well, India could not do much because we had seen our independence back then. The country was struggling with a shortage of food. Because of unbearable British Loot In India, we suffered a lot and it was trying to overcome the problem.

But Today Everything has changed in India and its time to showcase the real might to the world.

So I was just comparing their prospective launch vehicles


So they all have solid motors for the lower stages. Their initial Vikram-1 would have the uppermost stage powered by hydrazine. The follow-on Vikram-2 & Vikram-3 would have their  ̶u̶p̶p̶e̶r̶m̶o̶s̶t̶ ̶s̶t̶a̶g̶e̶  next-uppermost/penultimate stage powered by methalox, once that's developed. The Vikram-3 would feature solid strap-ons as well.

So their goal is to use the simplest technologies they can, in order to get started and get to market sooner. They can then develop better technologies in the meantime.

But once you develop the higher-Isp methalox engine, and use it to replace the 3rd stage, then what are your best upgrade paths from there?

Would you eventually try to cluster methalox engines and make that your central core, adding SRBs around it, Ariane-style?

Competing against Rocket Lab becomes harder as they achieve reusability on their booster.
We've now seen the 6th consecutive re-use of a Falcon-9 booster, and once Rocket Lab successfully recovers its booster with its electrical turbopumps, they may likely succeed at multiple re-flights as well, further lowering their costs.

If Skyroot were to develop a methalox engine, and then eventually use it as a the basis for a methalox core stage, then that would open up the possibility for its recovery and re-use as well. Since methalox doesn't suffer as badly from the coking problem as Electron's RP-1, then it allows for more potential re-flights per booster.

On the other hand, even solid boosters have demonstrated the ability to be recovered and re-used, such as the US Space Shuttle's SRBs, which were even able to splash down in the ocean via parachute, without having to be caught or spared from seawater.

Could solid core stages on a small rocket be more economically recovered and refurbished for re-use?

If Skyroot's primary goal of getting to market asap is reflected in their initial technology choices, then would a secondary goal of further reducing launch costs asap by finding a path toward re-use then be the next best focus of their technical efforts?

I’ve always understood that solid booster reuse was much less appealing because the fuel is a much larger percentage of the total cost, perhaps the majority?  As contrasted to using industrially produced liquids which are added at launch, it uses a chemically and structurally complex version of an *explosive* which must be cast in a specialized facility and transported with the rocket body.

Additionally, I think the booster structure itself is simpler - no tanks, ‘just’ a void.  (I’m sure that’s oversimplifying). That makes it cheaper, but further drives down the value of reuse.

Okay, so I just want to make another correction here to what I previously said. I previously thought that they would later introduce a methalox engine to replace the uppermost hypergolic stage on their initial vehicle, but instead their plan is that the methalox engine would replace the solid motor stage immediately below the hypergolic one.

But why do it that way? That then gives you a launch stack with 3 different propellant technologies to manage and operate.
Why keep that uppermost hypergolic engine, instead of having the new methalox engine replace both the hypergolic and the solid motor immediately below it? What possible advantage would a hypergolic engine offer that a methalox engine doesn't? Does hypergolic perhaps offer slightly more precise control for a more precise injection of the payload into orbit?

EDIT: Maybe that's it - maybe the methalox engine wouldn't be restartable, and only the hypergolic one is. So the upper methalox stage on Vikram-2 & 3 would improve the Isp  and deltaV (poor man's CUS?), while the uppermost hypergolic stage then does the precise orbital injection, including even possible multi-orbit injection due to restartability.
But where do you evolve from there? What's the easiest upgrade path? Clustering of liquid engines? Making methalox engine more precisely controllable and restartable? Upgrade from smaller strap-ons to larger parallel SRBs?

Methalox stages need insulation and also suffer from boil off requiring extra mass. So this wouldn’t be useful for a small launcher if they need a low thrust propulsion system for orbital injection.

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.

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.

  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!

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.

Hyderabad-based Skyroot Aerospace raises $51 million in Series-B funding

https://www.moneycontrol.com/news/business/skyroot-aerospace-raises-51-million-in-series-b-funding-largest-ever-in-spacetech-sector-9123531.html

Quote
Hyderabad-based space tech startup Skyroot Aerospace has raised US $51 million (Rs 403 crore) in a Series-B financing round. This is the largest funding round ever in the Indian spacetech sector, a release by the company claimed.

In contrast, Accenture recently announced that it has invested $25 million in Pixxel in a series A funding round. Chennai-based Agnikul Cosmos has, as of now, raised $11 million in Series A funding and is reportedly raising further funds in a new round; Hyderabad-based Dhruva Aerospace, in October 2021, raised Rs 22 crore or around $2.7 million.

Singapore-headquartered GIC led the funding round. Mayank Rawat, Managing Director of GIC India Direct Investment Group will be joining Skyroot’s Board, the release said.

Rothschild & Co India were the financial advisors for this funding round. The added fund will help expand Skyroot’s engineering team which currently has close to 200 employees, a release by the company said.

Currently, Skyroot has been working on developing the country’s first privately developed space launch vehicles. Their Vikram series rockets are built with an all-carbon-fibre structure and can launch up to 800 kg of payloads to Low Earth Orbit (LEO).

No NOTAMS for PRARAMBH launch?

Private entity Skyroot may not publish Launch Brochure like ISRO does but NOTAM is aviation requirement?

India launches first private space rocket.

India successfully launches first private space rocket Vikram-S.

11:41 18.11.2022

NEW DELHI, November 18 - RIA Novosti. India on Friday conducted a successful launch of its first privately owned Vikram-S space rocket, the Indian Space Research Organization said .

"Prarambh mission successfully completed. Congratulations to Skyroot Aerospace! Congratulations to India!" the organization said in a statement on Twitter.

The rocket was launched from the launch site of the Indian Space Research Organization on the island of Sriharikot. It reached a maximum apogee of 89 kilometers, while the target was at a distance of 80 kilometers.

The boundary of space is considered to be a mark of 100 kilometers.

Earlier, Skyroot Aerospace, the developer, reported that the launch was scheduled between November 12 and 16, but its dates were shifted due to weather conditions.

The Vikram-S rocket is a single-stage suborbital launch vehicle, and its launch will help test and validate most of the technologies in the Vikram series of space launch vehicles, said Nag Bharat Daka, COO of the company.

The launch vehicles are named Vikram after the founder of the Indian space program and famous scientist Vikram Sarabhai.

So Vikram-S is meant to pave the way for Vikram-1, which is scheduled for launch to LEO in Q3 of 2023:

https://www.business-standard.com/article/current-affairs/skyroot-successfully-launches-india-s-first-private-sector-rocket-vikram-s-122111800348_1.html

...
The Vikram-S rocket aimed at validating 80 per cent of technologies that will be used in the Vikram-1 orbital vehicle, planned for launch next year. The rocket carried three payloads built by Andhra Pradesh-based N Space Tech India, Chennai-based start-up Space Kids, and Armenian BazoomQ Space Research Lab.
...

https://theprint.in/science/5-minute-flight-2-indian-1-foreign-payloads-india-to-launch-first-private-rocket-today/1222748/

Quote
...
The 2.5 kg Space Kidz India payload was a satellite built by middle school students from India, Indonesia, Singapore, Seychelles, and the US, CEO and founder Srimathy Kesan told ThePrint. It contained a a microcontroller and ten sensors designed on eighty 4 cm x 4 cm printed circuit boards (PCB boards). The sensors were for measuring temperature, humidity, pressure, volatile organic compounds and gases, light and Hall effect. There are also infrared sensors, gyroscope, accelerometer and magnetometer.

“As part of our vision to make space as accessible and economical and provide hands-on experience for children we have named the satellite FunSat,” Kesan added.

The other Indian payload was called LakshyaSat-2 and was a 200g, 1U (unit) cubesat built by Tenali-based startup N-space Tech, with sensors.

“The purpose of the mission is to test if the payload can withstand the harsh space environment,” said founder and director Divya Kurapati. “The next version will fly to low earth orbit with Skyroot in the future.”

The third payload was an international satellite from the education non-profit Bazoomq Space Research Lab in Yerevan, Armenia.
...
The rocket was powered by solid fuel and uses all-composite materials. It also used 3D-printed solid thrusters for spin stability.
...
Next for the company is the launch of its Vikram-1 commercial vehicle with three solid stages and one liquid stage (solid and liquid propellants) towards the end of 2023.

Building Vikram-S has been extremely challenging than what we imagined when we started it 2yrs ago. It experiences 16g’s & 8 times the aerodynamic and thermal stress vs the Vikram-1. Getting the aero and flight dynamics right was a nightmare needing a ton of simulations & tests.

Building a rocket and launching it to Space is highest levels of precision and perfection at play. No wonder why it’s so difficult &very few companies achieved. Extremely happy we cracked it in 1st attempt. Journey has been learnings for a lifetime for @SkyrootA team🚀

Well, it was a sounding rocket which used spin-stabilization, without even any active guidance. It made it to the 80km mark, which is technically below the Von Karman line of 100km. But good enough - it wasn't meant to set any records, it was just meant to test some basic hardware that could be used on their Vikram-1 orbital launch a year from now. And very importantly, it was done very cheaply.

I think this is intended as the second-stage engine of their Vikram II rocket. I wonder if they plan to quickly move on from Vikram I (which has solid motors on both its first and second stages), using it more as a testbed for the first stage (which is shared with Vikram II) rather than an operational vehicle in its own right.

So this 3D-printed Dhawan-2 engine from Skyroot is LOX-LNG

from the video description:

Quote
Skyroot Aerospace successfully tested ‘Dhawan-II’ on 31st March 2023, the upgraded version of 'Dhawan- I' India’s first privately developed Fully-Cryogenic rocket engine which was test fired in Nov'21. The engine which is completely 3D printed has undergone long duration endurance test for 200 seconds, a record for Skyroot, making it a major milestone for our Cryogenic program. The engine has been named in honour of eminent Indian Space scientist Dr. Satish Dhawan.

Dhawan - II uses Liquid Natural Gas (more than 90% Methane) and Liquid Oxygen as cryogenic propellants, which are high-performance, low-cost, and green. This engine has a vacuum thrust of around 3.5kN at total area ratio and will be used in the upper stage of our orbital vehicle Vikram-2. The mobile test stand was indigenously developed by Skyroot and test firing was conducted in one of its kind facility of our partner Solar Industries at Nagpur.

Presenting you a snippet of our Raman-I engine test which captures varying pulses from 10 seconds to 60 milli-seconds.

More details about the Raman-1 engine and the qualification test below👇(1/9)

Quote
(2/9)

As Vikram-I launches to space, aerodynamic disturbances and thrust misalignments can make the vehicle roll about its axis, needing a responsive roll-control system.

Quote
(3/9)

It is provided by four Raman-I engines through precise pulses, commanded by the autopilot algorithm of our mission computer.

Quote
(4/9)

‘Raman’ is a series of engines/thrusters using earth storable hypergolic propellants for upper stage engine and attitude/reaction control in Vikram-1.

Quote
(5/9)

We demonstrated engine technology with hypergolics 3yrs ago on 30th July 2020 and based on it designed Raman-1 for roll control and Raman-2 as a single higher thrust regeneratively cooled upper stage engine for Vikram-1.

Quote
(6/9)

Propulsion for roll control requires rapid response and needs to be versatile, supplying adequate thrust from atmospheric pressure to the deep vacuum and with widely varying inertia.

Quote
(7/9)

Towards this, the Raman-I engine test has completed endurance with nominal and off-nominal chamber pressures, mixture ratios and pulse widths.

Quote
(8/9)

Raman-1 qualification test:
Propellants used: MMH/N2O4 (Hypergolic)
Peak Vacuum Thrust: 890N
Total Pulses/Restarts: 280
Minimum pulse width: 1/17th a second
Cumulative burn time: 104s
Total test duration: 352s

Quote
(9/9)

Raman-1 Construction:
Thrust Chamber body & Injector: 3D printed
Throat: Metal Matrix Composite
Chamber Thermal Protection: High temperature composite

In a momentous development, we successfully completed the carbon-fiber winding and curing of our majestic 10 meters long, 1.7 meters diameter, Stage-1 motor case for Vikram-I. This is the largest hardware we ever manufactured, and was built meticulously in-house using our multi-axis high precision robotic machine, powered by our proprietary software. This stage, named ‘Kalam 1200’, is designed to generate a peak thrust of 120 tons.

This black marvel is carefully designed to take enormous combustion pressures and temperatures while being super light- a very challenging balance. Massive hardware (almost the length of a city bus) needs massive effort right from the tooling to manufacturing and handling- took us few good years of iterations and learnings to get to this size and efficacy 🚀

ISRO Supports a space start-up's Rocket Engine Test


July 22, 2023

On July 21, 2023, ISRO demonstrated its commitment to fostering the space ecosystem in India by enabling a successful rocket-engine test conducted by Skyroot, a Hyderabad-based space start-up, at ISRO Propulsion Complex (IPRC) Mahendragiri. The test took place in the Liquid Thruster Test Facility (LTTF) in IPRC. The testing was enabled by IN-SPACe.

The test involved the Raman-II engine, which was designed by Skyroot to generate 820 N (Sea Level) and 1460 N (Vacuum) thrust, with a nominal chamber pressure of 8.5 bar absolute. The regeneratively cooled engine, manufactured through additive manufacturing techniques, utilizes Mono Methyl Hydrazine and Nitrogen Tetroxide as propellants. The 10-second duration test achieved the expected performance in terms of start transient, steady state, and shut-off. Skyroot intends to integrate the Raman-II engine into the fourth stage of its launch vehicle, Vikram-I.

The test facility systems demonstrated normal performance during the test, meeting the engine inlet conditions at T0. The instrumentation systems also performed as expected, further ensuring the accuracy and reliability of the test results.

This facilitation underscores ISRO's commitment to nurture private players, start-ups, and Non-Government Entities (NGEs) in developing the country's space eco-system. Going forward, a series of additional tests are planned to further validate and refine the Raman-II engine's capabilities.

Very nice, of course, but when are we going to see Skyroot's satellite launch? It was originally scheduled for Oct/2023, meaning this month, can they at least state a launch date, and the name of the satellite.

I see that they're now ramping up their marketing, churning out the musical montage videos.

I dunno how they came up with the name "SkyRoot" of all things. To me, it feels like it's just a riff on "Blue Origin" 
(Blue-->Sky,   Origin-->Root).
Their original logo likewise seems like a riff on the SpaceX logo:



They've since rebranded with their newer logo:



https://en.wikipedia.org/wiki/Skyroot_Aerospace

Quote
Their logo subtly crystallizes the acronym 'SR' of SKYROOT into a rocket-plane, while the sharp edges represent their "cutting-edge tech."

Does that winged logo then maybe hint they'd like to make a winged re-entry vehicle eventually one day?
Well, sometimes a logo is just a logo.
