Agnikul
« on: 07/28/2018 01:09 pm »
Agnikul appears to be a launch startup based in Southern India - have a look at their site:

http://agnikul.in



Also found some info on LinkedIn:

https://www.linkedin.com/company/agnikul-cosmos



The name roughly means "place devoted to the art of fire" (Agni = Fire, Kul = Guild) and their rocket is called Agnibaan (Agni = Fire, Baan = Arrow).

Their rocket Agnibaan is spec'd as 2-stage kerolox, using cluster of 3D-printed engines with built-in regen cooling  (that part reminds me of Rocketlab), but apparently their plan also involves air launch from a balloon (that part reminds me of Zero2Infinity's Bloostar)

No details on whether they plan to use batteries/electric-turbopump (should it be assumed?)

They want a plug-n-play architecture for flexible configuration, to allow up to 100 kg of payload to orbit.

Space startup Agnikul Cosmos raises Rs 3 Cr in seed funding


https://timesofindia.indiatimes.com/business/india-business/space-startup-agnikul-cosmos-raises-rs-3cr-in-seed-funding/articleshow/67981962.cms

Quote
Aerospace startup incubated at IIT-Madras’ incubation cell, Agnikul Cosmos, has raised Rs 3 crore in seed funding from seed-stage investment firm Speciale Incept Advisors.

The startup, which is working on manufacturing orbital launch vehicles for smaller payloads, aims to use the funds to accelerate prototype development by strengthening infrastructure and increasing team size. Working out of the National Centre for Combustion R&D at IIT-Madras, Agnikul was co-founded in by engineers and space enthusiasts Srinath Ravichandran (CEO) and Moin SPM (COO). They design and build launch vehicles capable of carrying around 100 kilograms of weight to lower earth orbits, thereby offering smaller satellites and other operators a more viable option. The startup uses additive manufacturing techniques including 3D printing tech for its engines.

“Speciale [the investor] brings a lot of industry connections and are also experienced deep tech-focused investors who can guide us as we scale up,” Ravichandran told TOI, noting that the funds would help the startup integrate its efforts and take them closer to prototype testing.Vishesh Rajaram, managing partner, Speciale Incept Advisors, said Agnikul’s propulsion tech and its ability to leverage additive manufacturing impressed the firm, which has a fund of $20 million currently.

The company said configuration of its launch vehicle is in place, and it expects to put the first flight into orbit within the next two years, with test procedures being ongoing throughout 2019.

Huh, the website has been calling it the "Agnite" engine, not sure if that's a translation issue or a change of plans. The site also says they're using a 7/1 architecture, which would mean this engine will also be used on the first stage in a cluster of seven, but that might have changed too.

Come to think of it, the site says the "Agnite" engine has a sea-level thrust of 25 kN, while the description of the video says the thrust is 1.2 kN at sea level. So maybe it is a different engine (and a change of plans).

Agnikul Cosmos Signs MOU to Use ISRO Facilities to Develop Launch Vehicle [dated Sept. 17]

Quote
Indian startup Agnikul Cosmos signed a framework memorandum of understanding (MOU) with India’s Department of Space on Friday for access to ISRO facilities and expertise for the development of its two-stage small-satellite Agnibaan launch vehicle.

“The Framework MoU…will enable the company for undertaking multiple tests and access facilities at various ISRO centers for testing and qualification of their single piece 3D printed Semi Cryo engine and other systems. The MoU also enable Agnikul to avail technical expertise of ISRO for testing and qualifying their space launch vehicle systems and subsystems,” ISRO said in a press release.

<snip>

The company’s two-stage Agnibaan rocket is designed to launch payloads weighing as much as 100 kg (220 lb) into 700-km (435-mile) high orbits. Depending upon the mission, the first stage can be configured to include 4-7 printed Agnite electric-pump fed engines powered by liquid oxygen and kerosene.

The second stage will have a single vacuum optimized Agnite engine. Agnite engines will be 3D printed using additive manufacturing. A third stage could be added for selected missions.

“Agnikul successfully test fired the world’s first 3D printed rocket engine – Agnilet. This higher stage semi cryogenic rocket engine is unique because it is completely 3D printed in one run, as a single component. Agnikul is the only company in the world that has designed a semi cryo rocket which can be fully built using 3D printing technology in one shot,” the company said in a press release.

<snip>

Agnikul aims to complete its first launch in 2022. The company has signed an agreement with the Alaska Aerospace Corporation (AAC) to launch from the Pacific Spaceport Complex — Alaska on Kodiak Island.

Agnikul and Alaska Aerospace Corporation are working together to obtain regulatory and export control approvals from the Indian and American governments for an initial test launch sometime next year.

A couple of more quotes about their plans to launch from PSC-A in this article, but nothing that's particularly revelatory.

I remain confused about the situation with "Agnilet" engines vs. "Agnite" engines. I asked about this over a year ago, but despite continued public development of the Agnilet engine, AgniKul's website still talks about Agnites. Although, there is mention of Agnilet, just not on the page discussing the Agnibaan vehicle. Makes me wonder if Agnilet is more a proof-of-concept for Agnite, or maybe AgniKul wants to pivot to in-space propulsion, selling the Agnilet directly to satellite manufacturers.

Yes, there's some confusion with their engines. Their official blog and news reports mention that they're developing two engines - Agnite and Agnilet.

We are humbled to announce that we have partnered with EOS (a global leader in 3d printing) for making our rocket engines — Agnite & Agnilet — fully in-house.

https://www.dnaindia.com/science/report-indian-start-up-agnikul-successfully-test-fires-fully-3d-printed-semi-cryo-rocket-engine-2874077
Quote
So far, the team has test-fired its second [stage] engine-Agnilet(1.2kN thrust), while the first stage engine-Agnite (25kN thrust) is expected to be test-fired later this year.

There's no mention of Agnilet in the "Products" section of their website where they describe Agnibaan launch vehicle: https://agnikul.in/#/products
Quote
STAGE 2
Our second stage is powered by the Agnite vacuum optimized engine. Sea Level Thrust - 25 kN. Agnite is the same engine that powers our first stage as well. It can deliver upto 355 seconds of Isp in vacuum. Running an electric pump fed engine offers greater & finer propellant utilization techniques to enhance payload capacity.

STAGE 1
Agnibaan’s first stage is powered by 7 Agnite engines each delivering 25 kN of thrust at sea level. All of these engines are electric pump fed engines allowing for simplified engine design and highly configurable engine clustering architectures.
Capable of operating with a sea level Isp of 285 seconds, the entire combustion section here is a single piece assembly and 100% 3D printed.

Conversely, there's no mention of Agnite in the "Engineering" section of their website describes. They just have information related to Agnilet: https://agnikul.in/#/tech
Quote
Agnilet - A single piece, 3D printed, semi cryogenic engine.

Our Agnilet engine is unique. It is entirely 3D printed and in one piece. 1000’s of parts have been carefully designed to be captured in this one piece of hardware. It is capable of about 3kN of thrust at sea level and drives our Agnibaan’s higher stage. 3d printing is magic! If you want to learn more about this, please check out our blog

Also note the discrepancy in Agnilet thrust numbers - 1.25kN in news reports vs 3kN in their website.

And, they recently tweeted this:
Quote
The wait for a new Agnite engine to be integrated starts now

It looks like they are indeed working on two engines, but not sure how Agnilet would be used. One of the news report above mentions that it's the second stage engine, but the official Agnibaan literature doesn't mention it. May be they've changed their design to have Agnite(s) for first stage, and Agnilet(s) for second stage? Somebody from Agnikul should clarify.

Agnikul Cosmos, the space tech startup incubated at the Indian Institute of Technology Madras, will apply for a patent for its full-scale, second-stage engine Agnilet, which it claims is the world’s first single-piece 3D-printed rocket engine. This means it’s been made in one shot without the thousands of parts that are typically assembled in a conventional rocket engine.

Agnikul Cosmos said that the Chennai facility will use additive manufacturing technology to build 3D printed rocket engines, and will be used to produce engines for its own in-house rockets.

Quote
Srinath Ravichandran, chief executive of Agnikul Cosmos, said that the facility presently has the capacity to build two rocket engines from scratch, every week. This will allow the factory to produce eight engines every month, and build the number of engines required to launch Agnibaan – its two-stage launch vehicle, expected to launch by the end of the year.

Quote
The company said that it already has partners who are preparing small-sized satellites to be launched on the Agnibaan rockets, and the factory will address this demand. Agnibaan is an ultra-light launch vehicle that is lighter than the Indian Space Research Organisation (ISRO)’s upcoming small, light commercial rocket – the Small Satellite Launch Vehicle (SSLV). While the SSLV can carry payloads of around 300kg, Agnibaan will be able to carry payloads of up to 100kg to low Earth orbits (LEOs) of up to 700km above Earth.

Wait - so they can change the number of liquid engines on their first stage?
I've never heard of anyone doing this before. I've heard of launchers which can be reconfigured through different modules/stages, and this might change the number of engines.
But I've never heard of anyone being able to change the number of engines on a stage as a mission parameter.

Does this just really mean they have different versions of that first stage? How customizable is this?
