As new solutions are put together and tested, they bring with them requirements for more fuel to lift the addition weight of the ship with the new, and often heavier, heat shields. At some point, the cost of fuel to slow down the ship’s speed before entering earth’s atmosphere becomes more viable. Slow down then simply fall to earth. A significant reduction in surface heat during reentry.
Have you ever owned an air hockey table? Simple technology but those air holes always eventually get clogged and can be a pain to keep clear. A heat shield with holes for ullage gas or liquid-film cooling would have to keep those holes open and that could significantly add to maintenance headaches.
Water is the way to go. As kids, we experimented with boiling water in a paper cup set into the coals of a campfire. Indeed, you can boil water in a paper cup. Using a water layer behind the ship's SS hull in critical areas and may also serve to shield the crew from space radiation.
Water would freeze in the channel due to contact with the fuel tanks unless completely empty. It's great for heat absorption. But may also cause a blow-out if icing at any point comes against the pressure of steam between two thin layers of metal. Methane may cause carbon fouling over time when burning off in contact with atomic oxygen in the upper atmosphere. We may be stuck with a dedicated nitrogen tank. Carbon dioxide may also be an option given the Mars return core mission, since it would not freeze if the plumbing were sufficiently separate from the main tanks. It may still freeze at those temperatures, but not nearly as readily as a water system would. It's not impossible that it would also foul the system if the carbon were sufficiently heated to disassociate from the oxygen in CO2. I'm sure the Chem-E staff at SpaceX are having fun with this one. It has to work in the chemistry of both Earth and Mars atmospheres, so lab time is doubled.
I'm visualizing thin sheets of stainless cut and configure such as to go on like fish scales. Then you just run the coolant between the scales. I'm still wondering if you could configure a electromagnet skin to push the plasma away from the ship.
I was 12 when Neil Armstrong stepped on the moon. I watched it on a 12" B&W portable TV in the display window of a news stand while my mon did laundry next door. Even at 12 yrs old, I recognized the historic significance of what I was watching. I am eagerly anticipating witnessing the same on Mars.
To think, the only reason we had been using ceramic tiles all this time was because it was easier for single-use purposes. It was good enough. But makes sense it is too fragile for reuse.
The only demonstrated replacement for the Space Shuttle tiles consists of thin columbium (aka niobium) metal panels (aka shingles) covered with a tightly adhering ceramic coating to prevent the metal from oxidizing and eventually experiencing burnthrough. Those FS-85 niobium panels were 0.4 mm thick and were tested to 2600F (1423C) successfully for 100 Shuttle EDL heating profiles (temperature and time) and tensile and bending loads without any unbonding of the ceramic oxidation prevention coating. Those panels require mechanical attachment hardware similar to the hardware now used to attach the ceramic fiber tiles to the Starship and flexible ceramic fiber thermal insulation between the panel and the hull of the vehicle also similar to the blankets now used on Starship. SpaceX has a lot of experience with niobium since the nozzle for the Merlin vacuum engine is made of niobium. Side note: My lab spent three years (1969-71) developing and testing ceramic fiber tiles and coated niobium heat shield panels during the conceptual design period of the Space Shuttle project.
point the bottom side away from the sun and spray water to make a lot of ice on that side. The ice can make a nice shield that will melt away as it does it's job. Then the thing is all lighter when it lands. Nice! Ice!
The strangest thing happened to me a little while ago. I had this visionary idea of a new Starship Heat Shielding method. And I called it "Ionic Thermal Shielding" using a strong field of ionized particles on the heat tile side of the Starship creating a barrier between the frictional reentry heat and the Starship that would drastically reduce the heat that the Starship heat shields receives. It struck me as strange that I would think of such a thing so I decided to Google it and Google has a new thing called "AI Overview," which I didn't know about. The Artifical Intelligence came up with the same thing that I did and by the same name, saying it's an actual technology they're working on to "shield spacecraft on re-entery into Earth's atmosphere." 🤩🤔
Now if they use methane as a coolant or heat shield, won’t that compromise the fuel system? Heating fuel is not a smart idea for many reasons and what about extra weight with metal shield?
Tungsten Metal for the hottest spots. or a special silica glass? maybe tungsten and carbon alloy? or some type of advanced ceramics? OH OH METALLIC BORON!!!!! it has melting point of over 3000 degrees F.
@@colonbina1they will be doing a metallic glass type of heat shield which is metal but it is formed in the structure or shape of glass... You can look up metallic glass... The ullage will be the starlite compound...
I wonder if a phase change material could be used to fill the jacketed shell of a heat shield. It would need to be a designer material but the limited amount of time its needed seems like it could be possible option.
I'm no rocket engineer, but I'm just putting this out there. Could an Electromagnetic Heat Shield be possible. Since Plasma is receptive to Electromagnetic fields, couldn't they make the heat shield repel the plasma. Like I said, I'm no engineer. Maybe the apparatus involved to make this happen would be prohibitive to spaceflight, i.e, too heavy, too advanced? I'm sure some people smarter than I would have tried it if it was possible. The best way to deal with the heat of re-entry is to not let it touch the ship. Maybe using it in combination with ullage gas cooling?
I don’t think magnetics would work given the extreme force with which the air molecules are being slammed against the hull, but Ive got to give you serious points for out of the box thinking.
The discolouration was aluminium coated on the steel so they could see on the cameras what temps they got without lots more sensors. Yes they coated the tops of the flaps with aluminium. Why it started discolouring way before the temps steel discolours
The reason why there will be metallic glass heat shields it's because forming this is extremely difficult and you cannot form huge sections of the ship with this material unless you have huge machines that can instantly cool down the metal.
At 1500°C, coolant will vaporize, buble will appear and corrode the inner surface of the heatshield. I remember original Musk planned to use 310 grade stainless steel. Outer shell should use this material instead of 304L. 310 can mantain its strength upto 910°C. Sure there should be auxiliary systems like pump, recirculation system for coolant, added weight to both vehicle, or other genius idea from the team! Very exciting to see!
Perhaps a comparable in between ceramic heat shield tile and these metal tile would be interesting. If the metal is tougher such it isn't subject to the damage seen with ceramic tile. And of course there are limits with current chemical reaction propulsion methods. But that doesn't mean there can't be other ways. For example propellate heated by directed energy from surface stations. Or a plasma drive with a similar power source. If only for the first stage. Or in time, aneutronic fusion impulse from the ground to orbit and beyond.
The solution? Pulling all ideas from the different fields of engineering I worked in dealing with heat. 1 solution would be to make stronger heatshield on the sides for catching that can handle the bumping off of the sliders on catch arms but still needs a deployable catching head like superheavy. 2 would be to create corrugated steel that can be filled with cryofuel for initial cooling then expelled though micro vent holes to create film cooling. The film cooling calls into question how much fuel would be needed to cool for re-entry from LEO or returning from lunar or Mars orbit vs the fuel needed for a long enough de-orbit burn to accomplish the same goal but still need a deployable catching head. Once there is a large enough space station for actual tourist any organic matter from human waste to food and plant waste easily makes CH4, so visiting starships can get enough fuel for re-entry.
Elon, have you considered the use of Ionic Thermal Shielding as a sort of "Star Trek" shield in conjunction with your new metal shields to create a complete barrier between the frictional reentry heat and the Starship.
@colonbina1 they will be doing a metallic glass type of heat shield which is metal but it is formed in the structure or shape of glass... You can look up metallic glass... The ullage will be the starlite compound...
The reentry plasma temperature is above 6000 K!!!! There is no material in the world that could withstand that without burning and evaporating. So any rapid reusability is a profoundly stupid dream.
Not trying to be a back seat driver, I realize spaceX knows ALOT more then me, but here goes. Why doesnt spaceX manufacture 1 giant titanium heat shield that just attaches to the bottom. Based on my backyard research titanium can withstand 3000F more then enough for re-entry, it would allow for a quick turn around as you dont have to check a couple 100k individual tiles. And if there is damage? You disconnect it and replace it with a new one (which is already prepared). And to save on costs the old one is recycled. I think it would add alot of simplicity. And also it appears titanium is lighter then ceramic (but ill admit i find conflicting reports on that). And yes i know im making it sound waaay more simplified then it is. But i think this would solve all there problems if it can be done efficiently.
One quick impression. The problem is not just how high a temperature the heat shield can withstand without meltiing, it also must not conduct that heat through to the stainless steel skin. Titanium conducts heat well; ceramic insulates and keeps the stainless temperature much lower. The actively cooled metalic shield they're talking about also keeps the skin temperature down by conducting the heat away.
There's nothing new about him wanting to use ullage gas as a virtual heat shield. It was, in fact, in the very first discussions Musk put forward about starship. Bye the bye, ullage is usualty prononounced without a leading jotation (y-sound)... and for reference, the j in jotation is pronounced with the leading y sound.
Does this mean starship will be dual wall? where/how is each metal tile for the heat shield filled up with a fluid? Where does the liquid come from? Can we get a deep dive metal heat shield tile video? 🥺 Please. I have so many questions

I'm very happy to hear that and I believe you... for now. But I've been seeing a rapidly increasing number of AI generated videos showing up in my feed and there will soon (and I do mean soon) come a day when it will be literally impossible to tell what's real or not on the internet. That day will also include "replies" from the "content creator" in the comments section that will also be AI generated. I strongly suggest that every human creator post at least one video on their channel that is a testimonial that they are indeed a real living breathing person. We are entering an Internet Dark Age of AI Deception.
I don't think they will use it on whole ship. Most likely there will be metallic heat shield in some parts like catching mechanism to reduce ceramic tiles number for easier refurbishment.
Yes I have an Idea - paint the unprotected parts with black heat resistant paint. This will improve the radiative cooling with at least 20%. But there is no point - this silo is doomed anyway.
The idea of a heat shield with thousands of holes through which to force gas or liquid coolant was already considered several years ago by Spacex, when the original idea was to build the hull from carbon fibre composites. The same idea of forcing air through small holes also helps some boat hull designs glide through the water more efficiently. In effect Spacex have already built a giant heat shield tile. It is the water deluge plate under the OLM.
Following NASA’s lead, doing anything NASA does would be extremely wasteful, dysfunctional, incompetent. NASA’s shuttle was an unaffordable, unsustainable disaster, just like Constellation & SLS.
@ NASA’s decisions crushed the US space program, resulted in wasting 52 years & $1 trillion since Apollo on dead-end boondoggles: Saturn V, Shuttle, Constellation, SLS… NASA keeps getting worse… no American has left Low Earth Orbit in over 5 decades. Defund NASA, it’s hopeless. Let spirited, innovative, efficient private enterprise take the lead.
7:28 The voiceover says "Mars mission" as we see a clip of a warm, wet and cloudy Earthlike landscape... yet another indicator that this video was created by AI and not a living, breathing human. I'm seriously starting to question whether 'GREAT SPACEX' is a human product. I hope I'm wrong but, it's not looking good.
Starship is doomed. The ship keeps getting taller and heavier while SpaceX is struggling to solve the rocket equation. More fuel ads weight, which reduces payload, adding a metallic heat shield will add more weight and will require more fuel. You can simply see block the 3 ship renders, and it's even taller. Cylindrical objects don't do well during reentry.
@colonbina1 I would suggest SpaceX go back to the first iteration of the BFR. It had a lifting body shape. Elon said that wings were useless in space, but reentry is a different story.
A lot of the current problems can be traced to the move away from the lifting body design. They wanted to be able to quickly rollout rolled water towers, but those are just not conducive to re-entry from orbital speeds. Boosters do ok because they only ever make it to at most 1/10th orbital velocity. Fabrication of integration of a lifting body airframe takes months, no matter how much rapid iteration you try.
methane as coolant is logical, however extremely dangerous when desiged as a leak through design to dissipate heat. Wouldn't that raise the possibilities of FUEL/METHANE leaking into the "super heated" flow in reentry and could make Starship a premium fireworks show. RUD
what are the costs of a bi-layer evaporative cooling system? added weight that does nothing and added fueling requirements. how much fuel will be needed to absorb the heat? are they already having issues with heat soak into the tanks? are the tiles that heavy? complexity- will a micro porous skin stay porous after a reentry and sooting? will a thin layer of stainless surve and serve the same purpose and resiliency ageists micro meteoroid strikes at tiles? I don't see evap cooling going so well.
you dont see it going well yet you have this many unanswered questions? liquid to gas cooling systems are not complex nor expensive and are some of teh first forms of cooling humans invented with plumbing, it would get rid of 10 tons of heat shields and they already have to bleed off fuel on re entry to lower their weight, you can clean micro pours with a solvent bath in a ultrasonic chamber or hand held laser gun for cleaning, heat tiles where not designed to protect the craft from micro meteorites in the first place thats a difrent technology the requires multiple layers of thin sheets of aluminum to be weight effective.
Sometimes, I feel like there are a lot of fillers, but this time, it is pure knowledge transfer. Thanks!
tell me the topic you want to discuss, I will find more about that

They need the same metal of Iron Man
It would be more effective if coolant would bleed much faster at broken tiles, putting the coolant where it is needed most.
Did SpaceX try to make heat shield tiles from Aerogel?
aerogel has oxygen in it, it would burn up faster.
and it's far too weak
I believe aerogel is too fragile in its present form! I'm sure he has a chemist working on it somewhere

See through inside Starship?
Essentially the Starship is being made to sweat.

Gps rapid response. Sounds like the military is concerned about our goa network being targeted during a war.

They wanted to be able to quickly rollout rolled water towers, but those are just not conducive to re-entry from orbital speeds. Boosters do ok because they only ever make it to at most 1/10th orbital velocity.
Fabrication of integration of a lifting body airframe takes months, no matter how much rapid iteration you try.

What's wrong?
@ the extravagant wording, the word choice, it just *sounds* AI
methane as coolant is logical, however extremely dangerous when desiged as a leak through design to dissipate heat. Wouldn't that raise the possibilities of FUEL/METHANE leaking into the "super heated" flow in reentry and could make Starship a premium fireworks show. RUD
what are the costs of a bi-layer evaporative cooling system? added weight that does nothing and added fueling requirements. how much fuel will be needed to absorb the heat? are they already having issues with heat soak into the tanks? are the tiles that heavy? complexity- will a micro porous skin stay porous after a reentry and sooting? will a thin layer of stainless surve and serve the same purpose and resiliency ageists micro meteoroid strikes at tiles? I don't see evap cooling going so well.
you dont see it going well yet you have this many unanswered questions? liquid to gas cooling systems are not complex nor expensive and are some of teh first forms of cooling humans invented with plumbing, it would get rid of 10 tons of heat shields and they already have to bleed off fuel on re entry to lower their weight, you can clean micro pours with a solvent bath in a ultrasonic chamber or hand held laser gun for cleaning, heat tiles where not designed to protect the craft from micro meteorites in the first place thats a difrent technology the requires multiple layers of thin sheets of aluminum to be weight effective.
