Full Duration 101 sec rocket engine test fire

BonNova completes a full duration test fire of its Lauryad Level I flight engine. The radiatively cooled graphite engine ran perfectly for 101 seconds with the nozzle glowing first red, then white hot.

The latest test is now posted (Video response above) youtube (dot) com /watch?v=NyFpJ7zsUiA

No thrust information and although it worked well for 101 sec the white nozzle would fail if run to much longer.

[teambnova]

You must not have seen the the latest hot fires.

[miniatureme95]

it was white hot!!!!!!!!!!!!

[teambnova]

You think that's white hot? Check out our latest test (Video response above) youtube (dot) com /watch?v=NyFpJ7zsUiA

[waspsnest]

why is there no divergent part of the nozzle, or is there a smaller throat further inside the chamber

[teambnova]

The interior profile is not the same as the exterior profile.

I can't help but stare at the rocks on the ground.....

[shizzle5150]

nice burn, nice machining, nice all around. When the spece program has failed us because of exorbitant spening, I hope that one day people will be smart enough to get off this rock. Taking calculated risks is what did it for appalo missions so lets give people a little breathing room on the regulations. We might just find a more efficient means.

You should put copper tubing around the nozzle, hook it to a compressor and tank of liquid nitrogen. You need to pull the heat away from that nozzle.

@SuperTrooper9000 If the rocket was moving through the air at high speed wouldn't the white hot nozzle keep cool?

@nivekevinutz water. When hydrogen (H) combines with oxygen (O) it burns (oxidises). Two hydrogen atoms (H2) combine with one oxygen atom (O) to form H2O, water.

[Armigo91]

As for rockets, we already experimented hydrogen on dozen of flights. Why we still dont have methane as a propellant is unknown to me. Its more efficient, can either be more efficient or deliver more power.

And it doesnt require cryogenic fuels as it is cryogenic in itself under pressure.

[Armigo91]

spoon the ingredients gets mixed. This same principle works in the formation of a born solar system. All kinds of ingredients clumb together (like rock, iron, other minerals, nitrogen, oxygen, hydrogen, and H2o obviously.

All those materials were mixed in the accretion soup in the formation of the early solar system.

That means that any any any planet must and will have water, whether its frozen liquid or air.

Your a naive hypocriet religious moron just to question that already fact.

[Armigo91]

But it drives us to put estimates or barriers on things we cant further look into. You know, thats perfectly fine with me. But its ridiculous and your a total brain defected mongol to even consider saying, earth is the only example of a planet with water, and theres one subject of people interpreting that as it was said. ANd theres a subject of people that take it as, this is all there is.

Gravity is like a cup of soup.

It has dozen of ingredients to it. And when your swirl it around with your

[Armigo91]

planets and moons likely havent because we cant see it. Hello!!!!

90% of the visible matter in our universe is hydrogen. And you only need 1 spark and some oxygen to light it.

And somehow its assumable to say the earth is the only planet in the universe that has large quantities of liquid water. Im not sure about the reasoning of many people on this planet. But i find saying that as a fact far more further fetched then saying aliens exists in large quantities.

AFter all its not my reasoning

[Armigo91]

@nivekevinutz

Im not gonna give you the direct answer. But last time i checked the universe was full of sparks and hydrogen.

But somehow mysteriously, perhaps with help of * kough* god.

All water and theirfore life tht exists is here centered on earth.

We are actual raising the question whether water exists on the moon or mars. Which is obvious logic, then why are the stars burning nuclear fusion?

So what we have said for decades and many still do. We see liquid water on earth, but all other
