TM65 Liquid Propellant Rocket Engine - Episode 1

http://www.copenhagensuborbitals.com
The TM65 Tordenskjold is Copenhagen Suborbitals's third liquid propellant rocket engine. The engine produces between 65 and 90 KN trust, which is equivalent to the order of 200,000 Horsepower.
The engine will be tested in may 2012 and will be Copenhagen Suborbitals' 12th test of a liquid engine.

any specific reason why the fuel/lox pipes are welded and not bent? to a noob like me it just seems that the rocket vibrations would be a less of an issue if there weren't any welds in the pipes

[boogiesg]

The diameter of those fuel pipes is large compared to the radius of the bends. A mandrel bend with the same radius as these would have a much thinner wall on the outsides of the bends. The fuel would flow more efficiently but the thinner wall would be much weaker structurally. The welds on the other hand, should actually be stronger than the original pipe if they were done correctly.

Is the piro similar to a pre burner

[Alan Haney]

if you had funding could you possibly get multiple tm65s and make a 2 stage orbital rocket that can go into the mid thermosphere and possibly like resupply the iss ?

[lordzeppo]

make more sense now but still,200 000 HP is a hell of a lot,turn that into a turbine and you've got a brand new energy source.

[weinbergerc]

oh, that said, if you make some assumptions, you can approximate KN to HP fairly accurately especially with a rocket in a known medium. And I assume the TM65 team did just that. I would think that's why I said, "to the order of..."

[weinbergerc]

I wish I could read my original comment since I have forgotten even writing it. Yeah, what I allegedly said makes zero sense. I wish I knew how I converted KN to HP without having to know distance or time, that would be useful!

Anyways, sorry for the troubles.

Cheers.

p.s. just to be snarky, hp is power, not work. "Horsepower (hp) is the name of several units of measurement of **power**, the rate at which work is done." - wikipedia

great video..

These guys are my new idols.

Wonderful engine, just seen the test video. Is the casing and injector head on that engine mild steel? I'm interested in developing a small liquid engine (much smaller) and thinking Aluminum casings. I'll certainly bear the film cooling in mind, I've heard of it for chamber but didn't think of doing it on the throat.

maybe to reduce weight

[kerimil]

cophenhagen suborbitals... I don't know why but my first thought was... kerbal space program :D
