Interstellar Technologies
« on: 03/14/2017 04:17 AM »
I think this team deserves it's own thread.

http://www.istellartech.com/

Youtube playlist of their recent tests

12 Kn engine fire, slightly on the melty side. Stated to be an upcoming sounding rocket engine



Vertical fire of the same, testing TVC systems



Older flight of a VTVL testbed

I'm glad someone made a thread about these guys, I was wondering about that rocket nozzle. I've never heard of a nozzle where the entire thing glows white-hot, top to bottom -- what's the deal with it, like what kind of engine bell is that? Is it ablative?

Anyway I love what these guys are doing on a shoestring budget. I'd love to see them get to the level where Masten is.

It's called radiatively cooled nozzle. merlin 1 Vacuum has it. And I think the RD-58MF is supposed to have a composite one. You basically use a material that can tolerate the heat and put some serious thermal barrier upstream.

Per their site, most of their engines are ablative, but it's quite common for these things to look a lot whiter in photos and video than they would in person.

Seems as per latest tests, they are experimenting with liquid cooling jackets just now.

They seem to have a page now talking about goals for the Momo sounding rocket. Also a users guide

http://www.istellartech.com/technology/momo

All 100% in japanese though and google translate fails, as well. Apart from 100km flight goal, i'm unable to parse.


Also there's a fairly google translateable history page now. Starts at 2005
http://www.istellartech.com/history

EDIT: Nah, there's a full english version of everything right here

Welcome to the forum, and thanks for dropping by !

Are you able to share some updates with us here, as well ? For example, what major upcoming milestones is the company looking forward to ?

Also, i've tried to become a member of your fanclub on Campfire, but unfortunately Japanese translation didnt get me far enough. Any chance you guys could start a Patreon account in parallel ?

Hi

I'm from this company too ;)

Our next mile stone is to launch sounding rocket MOMO.

Currently we are working on manufacturing the very first MOMO.
Next experiment will be our final full duration static fire test for MOMO which will be held soon.

On top of that, we are working on orbital rocket.
We are doing lots of calculations so that our orbital rocket will properly deliver satellites.
Our programs are uploaded here https://github.com/istellartech.
Its constantly been updated.

Experimental wise, we started to work on critical technology for orbital rocket, turbo pumps.
We have already done few experimental static fire test of gas generator to get a better understanding.


We thought about starting a cloud funding in kickstarter but unfortunately, we don't have a US bank account.

Excellent information above ! Thank you.

For setting up crowd-funding, try Patreon.com, and Paypal, it should not require US account.

Looking forward to it !

Is this what we are looking at here ?

Kickstarter has preannounced they are entering the japanese market (estimated fall 2017), which I assume means they will accept japanese companies with japanese bank accounts.

http://www.kickstarter.com/japan

Would be interesting as a "launch" campaign partner to be one of the first all japanese kickstarter campaigns.
