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
Injection Valves: Ultra-fast response
Nozzle: Scarfed (to tangentially flush to vehicle diameter from inside)

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 🚀

On the sidelines of our honourable Prime Minister's state visit to France, Skyroot and @PROMETHEE_Space, a leading French new-space operator of nano satellite constellations, have decided to partner to explore launching of a part of their Japetus earth observation constellation with our Vikram series of launch vehicles.

ISRO supported the testing of the Raman-II engine developed by @skyrootA
 at its rocket-engine testing facility at ISRO Propulsion Complex (IPRC), Mahendragiri, demonstrating its commitment to fostering the space ecosystem in India.

The engine test was successful.

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.

Exciting news! We've signed MoU with @PROMETHEE_Space, a leading French earth observation constellation operator, to provide launch services aboard our Vikram launch vehicles for their Earth observation satellite constellation. This follows the exploratory meeting between the two companies held in Paris this July.

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.
