BITS Pilani Hyderabad incubator to support India’s first reusable rocket start-up

The Technology Business Incubator (TBI) at the Hyderabad campus of BITS Pilani said it is incubating Abyom, a start-up that is working on India’s first reusable rocket.

Recognised by DPIIT, Abyom’s mandate is to build liquid propulsion rocket engine and testing system. “Liquid propulsion rocket engines are widely used on space launch vehicles in comparison to solid phase propulsion engines and other engine types such as hypergolic engines and liquid hybrid engines,” a TBI spokesperson said.

This technology will be used to build the country‘s first ‘reusable sounding rocket’, which will be very useful for those working in areas such as meteorology and agritech data.

Quote
“Our experience comes from college years when a variety of prototypes and tests such as static solid motor tests, parachute ejection tests were conducted and rockets were launched in the USA for the Space Port America Cup to a height of 10,000 ft,” Jainul Abedin, Founder and Chief Executive Officer of Abyom, said.

What propellants are they using? They talk frequently about "cryogenics," so I can probably guess that the oxidizer is LOX, but I can't rule out a semi-cryogenic kerolox engine, and nowadays both methalox and hydrolox are possibilities for "full" cryogenic.

(Excluding more exotic things like Isar's propane/LOX, but barring further evidence I'm assuming they're going with one of kerolox, methalox, or hydrolox.)

Looks like this one is ethanol and peroxide:

(This is a terrifying combination, they are miscible and form a very sensitive explosive that looks just like water if they leak)
I tried it at home

Interesting. Does the use of ethanol and peroxide for the test engines tell us anything about what they're likely to use for the real thing? My gut says "probably not hydrogen, since that's so unique that ethanol just can't replicate it," but my only training in rocket science is "I read Ignition! once."
