/sfg/ Starliner Verdict Version

[Anonymous No.11887631]

The internal clock malfunctioned and the computer couldn't tell the mission time.
A Second malfunction could've caused the capsule to hit the service module after separation.
And last but not least there was a communication net issue that stopped ground control from giving direct orders top the craft.

To the guy asking why no aerospikes have been used yet in spite of potential advantages, there are two primary roadblocks.
Firstly aerospikes are new and relatively untested, yes the XRS-2200 engine did perform quite a lot of burn time, but only in a test stand. No large scale aerospike vehicle has ever completed a mission of importance as of now. This creates inertia for it in an industry which up until just recently has been very sluggish to adopt any fundamentally new designs, due to the high costs and low payouts of rocketry till now.
The second issue is that some of the aerospike's performance hasn't yet lived up to expectations, mostly in my mind because the largest aerospikes built have been built using the plumbing of other, older conventional rockets, I don't personally think the technology has actually been fully matured, and it won't be until somebody builds an aerospike from scratch, to purpose.

Yeah they’re also pretty impractical. In the world of SSTOs, they’re amazing. But as soon as you have a vehicle like Starship, having one engine for all altitudes is not required.

Think of the aerospike as a “jack of all trades”. It’s good at both Sea Level and Vacuum. But it’s not great. However if you have a two stage vehicle, you can just use a Sea Level-Only and a Vacuum-Only engine on the respective stages. As such, who would want a “mediocre engine” on their vehicle when you can just have two differentiated ones that already exist and don’t need extra R&D.

This means that aerospikes only really are needed for SSTOs. However SSTOs have a whole host of issues already, and are now considered to be impractical due to their small payload mass despite being huge.

So long story short the fact that their only major potential application already is a shit idea pretty much is a nail in the coffin.

Also, pure SSTO is only necessary when there are multiple heavy worlds with people on them. Starship is SSTO everywhere in the system but Earth, Venus, and the gas giants themselves.

>(continuous altitude compensation with no moving parts)
they are simply contrasting aerospikes with variable geometry bell designs for altitude compensation (think thrust vector control nozzles on advanced fighter jets). There is nothing preventing you from gimbaling an aerospike engine just like you would a standard engine bell.

I'll repost my blogpost here then. I appreciate any suggestions and ideas.

I think I got a reaction started after dousing the HTPB+Saltpeter propellant in lighter fluid. However, the reaction was pitifully slow. The lighter fluid burnt faster than the propellant. Also, instead of burning at the face, the propellant appeared to have burnt from the inside. Which leads me to suspect that some other kind of combustion was happening other than HTPB+Saltpeter. Perhaps since the propellant was poured in a used steel cap that some iron oxide got diffused into the propellant and that was reacting. Either that, or the polymerization of the rubber ideal for combustion happens in an air starved environment rather than the kind that happens on the exposed surface of the rubber.

Overall, I might abandon the HTPB+Saltpeter concept and move on to other mixtures. I was thinking about moving back to "rocket candy" but instead of melting the sugar, I would bind the components together with the rubber mix I have, then later I would find something else to use.

[Anonymous No.11887924]

Skylon's payload mass ratio is actually better than most rockets-the starship-superheavy weighs over 5000 tons and can put about 100-150 tons of cargo into orbit, the skylon weighs about 325 tons and can get 15 tons into orbit. So a 33 to 1 ratio versus 21 to 1 ratio.

The big thing Skylon has to grapple with is driving the cost of the vehicle down-as envisioned it's about what you'd expect a standard rocket costs, but reusable,but at this point Starship is breathing down everyone's neck in terms of cost optimization. They do have a few other advantages over current gen rockets-the skylon should be able to launch is almost all weather, it can land at commercial and military airfields that already exist,and in many wysthe system is much better optimized for point to point human travel than the starship is since it's got nowhere near the noise problem that a monster rocket has.

I hope the brits build the thing and can make it competitive.

Cool but only if you have an equally reusable booster to launch it with. Otherwise it's basically a very big reusable, safer capsule, which is an improvement but not any kind of gamechanger.

No. SRBs can sit ready basically forever, so if you just make the main tank integral to the orbiter's lifting body, build a shitload of SRBs and stash them near various spaceports, you could use the Methalox Shuttle as a proper spaceplane. I see where you're going with this but there's room for both designs.

I've looked into that even if it's not my main interest.

It's not like the job market is completely dry. It's just that it died down hard with infrequent interviews with long lead times and slim picks for jobs.

I'm going to take a leaf from the DoD's page and use this to also prop up some incidental side projects.
I'd first start building a big-ass PROCSIMA array somewhere in cislunar space, with an attached space station that can accommodate up to 50 personnel for array maintenance and research.
Assuming this money is made available in the present day, Spacex is getting the rest of the SS/SH development funding they need, immediately. Gotta secure the development of supporting technologies for the mission, you know?
The probe itself (along with one or two identical ones, for redundancy) would get the bulk of its initial acceleration from a yeet train made of Starship-sized kick stages, and PROCSIMA beamed propulsion would take it from there.

Let's be very honest again. We don't have a commercially available heavy lift vehicle. Falcon 9 Heavy may someday come about. It's on the drawing board right now. SLS is real. You've seen it down at Michoud. We're building the core stage. We have all the engines done, ready to be put on the test stand at Stennis... I don't see any hardware for a Falcon 9 Heavy, except that he's going to take three Falcon 9s and put them together and that becomes the Heavy. It's not that easy in rocketry.

Okay yeah I won’t disagree. It’s more like a”gradient” where the atmosphere slowly gets more and more compressed until it turns into a slush solid, and eventually a solid surface. That being said, there is the probability that a gas giant could lose its “atmosphere” and all that is left is the exposed solid core. (I think it’s called a Chthonian planet or something?) If metallic hydrogen is metastable there’s a POSSIBILITY that there could be planets somewhere in the universe made up of surficial metallic hydrogen, because they used to be gas giants that got too close to their star

No, just use Methalox, launch it horizontaly from a huge rocketplane made from steel (probably inconel), give it an internal tank and vacuum optimized engines on the orbiter.
Doesn't have to be full flow staged combustion, fuel rich closed cycle is sufficient.

Maybe make the thermal protection system from inconel as well and you have a realistic 1970s shuttle that can at least launch more often without as much servicing.

Full flow staged combustion hasn't been possible before since the materials to sustain these temperatures, pressures and oxygen rich enviroments simply did not exist untill recently.
The fact that raptors oxygen rich preburner turbine is not burning up is one of the biggest advancements in that engine.

Okay my idea is this, if we can build inflatable rotating habs in space, why not just do it on the surface of the Moons and planets we colonize? It’s not THAT crazy of an idea. (pic related, something like that rotating section form the Nautilus X would work wonders). But I guess that’s besides the point because as far as we can tell the human body functions well in low gravity, as long as it’s not microgravity. Just work out and everything will probably be fine.

You'd blast a bunch of the water out of the pool if you jumped in. As far as jumping out from the bottom, no that would work only slightly better than on Earth. Your head and shoulders still have to push all that water out of the way, but you could probably jump out of chest deep water since your least hydrodynamic surfaces are already clear.

Low ISP, very high thrust solid rocket motors hidden behind blowout disks, cockpit/crew section is separate from the rest of the vehicle and only (relatively) weakly pinned into the rest of the vehicle's spaceframe. If something goes wrong during ascent the motors fire and literally rip the whole cockpit out of the ascent vehicle and since spaceplanes fly upside down during their gravity turn should carry the crew well clear of the rest of the vehicle.
If your spaceplane is small though like X-34, Dreamchaser, etc though it should be small enough that simple rear-facing SRB motors could carry it free of the booster vehicle without damaging the craft at all. Have the motors carry it down and away from the failing booster and then perform an automatic spin to get it right-side up and deploy airbrakes to cut speed, let the debris sail on past it.

Sustainable, but not really practical, especially not if you're trying to bootstrap to eventual full autonomy via ISRU. A lot of chemistry and industry is "easy" insofar as the processes are well understood and machinery to perform them has been invented and iterated on for decades, however many of these processes are also very energy hungry and require a constant flow of substantial electrical power.
You can't really perform that on a planet which is already only getting a fraction the sunlight of Earth which is also well known for sun-obscuring storms that can last for weeks or even months on end.
A mostly-independent Mars colony will by necessity require a supply of power which can work in a nearly airless environment without being reliant on the sun, this narrows it down to pretty much only nuclear. Geothermal requires a much better knowledge of local geology and necessitates active near-surface vulcanism, hydroelectric requires large bodies of fast moving water, petrochemical requires the aformentioned petrochemicals and a constant supply of oxygen, wind requires substantially thick atmosphere, and solar need both strong and constant sunlight.

What's left but nuclear?

I think at that point you'd definitely need some kind of ejector cockpit. I think though that the idea is that commercial rockets will be built more like commercial aircraft, with an abundance of safety systems and robust, reliable propulsion systems not prone to exploding quite so often. For an SSTO type vehicle so long as it doesn't explode outright, so long as it's plane-like enough you might still be able to recover control of it and glide it back to a runway or at least perform a water landing near a coastline.
I think the lesson though is to not try and fly SSTO's because they're poorly optimized for launches from Earth, packing in the extra flotation devices, extra control surfaces, and other airline-like safety systems will reduce their already pitifully small cargo capabilities even further.
