I believe this is an outdated design for you all, but I did have a question about cooling. From what I understand would you not want the fuel to spend as little time in the cooling chamber as possible? In order to maintain the highest possible temperature differential. Of course this would also be dependent on mass flow rate due to total heat capacity of the fuel when thinking about it as a control volume. But yeah you mentioned you want the fuel to stay in the cooling jacket for longer, but I was under the impression you'd want the opposite.
@Rasmus09096 жыл бұрын
You want the fuel to heat as much as possible and the chamber wall to be as cool as possible. These two contradict eachother and you need to choose a middle ground.

I have never seen a rocket engine with a combustion chamber so long. Just wondering why... is there a heat transfer issue? The equations that dictate chamber volume don't agree with a chamber of that size.

Dean Shaw I don’t know for sure, but I think it’s because of the low pressure on the feed side.

I like the Ball Valve design, Typically the H2o2 valves operate the same way. Does your injector design offer Boundary Layer Cooling? I thought I saw some alcohol injectors towards the outer edges.
@PyroShim9 жыл бұрын
Isn't the thermal conductivity of oxygen higher than that of alcohol? Also the oxygen would expand as it is heated, which would compensate for the pressure loss in the system.
@souravsinha76896 жыл бұрын
liquid oxygen would oxidise(burn ) the hot metal
@bandiras29 жыл бұрын
Re: PyroShim They need liquid oxygen to inject, becouse the injector design reqie liquid to operate properly. I think. High tech russian engines can use overheated oxygen gas, but that design is completly different than this.

The 0.9mm injection holes are drilled one by one. The larger holes are also simply drilled. They have mentioned that every time a drilling is slightly wrong, they need to throw away the steel object and make a new one. For their new BPM-100 engine they use prefabricated injector nozzles mounted in s plate with larger holes.

Seems a little amateur like to me. Bad quality welds, no deburring of the holes, rough machining, and apparently does not know about pneumatic regulation valves that is a whole lot faster and a lot more precise than just putting a servo on a normal valve and messing a little with the ball hole (as oppose to the proper seat on a proper regulation valve). And how is fuel pumped on this rocket? Fuel flow could be regulated by the pump in stead of the valve.
@quevicular7 жыл бұрын
fuk man, the welds are attrocious, lmfao. Just horrible to say the least. can you say BOOOOM!!!!
@sycodeathman7 жыл бұрын
Fuel flow is determined by tank pressure; the tanks are pressurized with nitrogen (or some other inert gas) to a level that will force fuel out of the tanks at whatever rate they've designed for. That fuel then flows through the engine plumbing and into the combustion chamber. This method of moving fuel in a rocket is called a 'blow down' pressure fed system, which results in low combustion chamber pressure and correlated low thrust, but is simple as far as liquid rockets go and is good for rockets that are designed to be as cheap and as simple as possible.
