Post Liquid Rocket Engine Tests   Posted on: Tue Dec 04, 2007 10:32 pm
Guys
Ona more technical note i was reading http://www.interorbital.com/Rocket%20En ... Page_1.htm

When were these tests done?

Are there currently more engine test scheduled?

Can we see any videos of the engine test images on the site?

Is there any chance of hearing how future engine tests go?

Who worked on the engines, and what was the procedure of testing other types?

Did you go through many engine ideas?

Sorry to bombard you with Qs here but the evolution of engines interests me and we see a lot of organisations testing and changing them over many months and years.

It must have taken a lot of testing to get as far as you have yet the site shows little info on progress in this dept. Is this because there is still a long way to go until an engine is at the level you require?

Also "Recently, IOS has begun testing a new type of liquid rocket engine using an expansion-deflection, altitude-compensating nozzle" sounds interesting!

Rob

I may be being a bit harsh here but it looks to me like IOS is one of those companies that could if it had the funding, but baring an angel dropping out of the sky is likely to bump along on hope and not much else.

They subcontracted some work for Burt Rutan back in 1997, and demonstrated they can build stuff. Plus they've done other contract work from time to time.

May 2005: Interorbital Systems successfully test fires a rocket engine with an expansion-deflection (E-D) nozzle.

is the latest news on their site about engine firings
However this link
http://www.thespacereview.com/article/808/1
gives some details of the sea-launched Pelican sounding rocket system they are developing/want to develop with Space Systems/Loral (SS/L),Microcosm & others.
It looks as though it depends on govt funding.
If they get the funding to do this I think they could pull it off given the work they seem to have done. But beyond that.
Selling tickets for a ride to space seems a little premature

Well funding seems to be everyones problem at the moment. If they can build a rocket wil the 1million and a bit more then the publicity alone could well get some more backing etc.

There is a chance i could be running another interview soon about a lot of the earlier work and how they got to where they are.

Its a tough game, just read rocket scientist's post about finding getting interest harder than he expected. Just got to get behind everyone and wish them luck!
