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 ties up with VSSC to test its 100% 3D-printed semi-cryo engine that'll be used in 2nd stage of Agnibaan launcher.

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.

The 10,000-square-foot facility is located at IIT-Madras Research Park. It will have a 400mm x 400mm x 400mm metal 3D-printer from EOS that will enable end-to-end manufacturing of a rocket engine under one roof

ISRO delivered Flight Termination System (FTS) packages to Agnikul Home/Flight Termination System (FTS) packages to Agnikul
Nov 11, 2022

Agnikul Cosmos, a space technology startup based in Chennai, received its first flight termination system (FTS) on 7 November 2022, from ISRO, with the support of IN-SPACe.

The official handing over event happened marking the culmination of multiple rounds of interactions about interfacing, handling and using these systems on Agnikul’s launch vehicle "Agnibaan", in the presence of Director, VSSC and IN-SPACe teams.

This also marks the first time that a system that has been used for ISRO’s vehicles is being supplied for supporting a private launch vehicle built in India. The package will be used for their fully controlled sub-orbital launcher, scheduled to launch from SDSC SHAR, Sriharikota.

Agnikul co-founder Srinath Ravichandran told TOI: “We are targetting the sub-orbital flight before 2022 end and we will soon make an announcement. The FTS delivery is a big step towards a guided, controlled flight, which needs to have the right safety mechanisms in place.” 5/n

Quote
“In that regard, this is one step in that direction where we’ll be directly interfacing with Isro systems.” A flight wouldn’t be possible without this system, he added. 6/n

Agnibaan, according to Agnikul, is a highly customizable, two-stage launch vehicle capable of taking up to 100kg to orbits around 700km high. 7/n

Quote
“...Agnibaan can access both low and high inclination orbits and is completely mobile — designed for accessing more than 10 launchports. Driven by LOX (liquid oxygen)/Kerosene engines in all its stages, Agnibaan is configurable by the customer,” it says. 8/n

Also, the vehicle need not fly with the same number of engines all the time. “The mission, the satellite and the launchport itself would decide how many engines go on the first stage. n/n

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?
