At least it isn’t an AI voice. I guess people doing voice work aren’t usually rocket scientists.

The voice says "abrasive layer" @2:50 and it should say 'ablative'

Why don’t they mold the vehicle with the heat shield. Like 3 massive pieces that are reinforced.

This video brought to you by the department of redundancy department. ;-)

An "abrasive layer" would be bad. You likely meant "ablative layer", but kept saying "abrasive". In general, higher temp materials are more brittle and thus less "strong". By "stronger" did you mean better thermal resistance or better structural properties? If an ablative layer was used, the thermal protection would have to be replaced after a re-entry.

Question I would ask, is if this secondary layer of heat protection that slowly burns off, could it build up and jam the hinge of the Starship flap preventing it from full motion?

Assume a tile falls off. What's to stop the ablating (melting and evaporating) material melting the material under a "good" tile beside the location? I can see whole strips of tiles peeling away because the material underneath each tile in turn has started ablating...allowing superheated and supersonic gasses to burrow UNDER the "good" tiles.

The "thinner" tile on IFT4 was an ablative tile. The experiment wanted to determine how well it performed when the outer ceramic tile is lost.

Ablative, not "abrasive" materials in the new heat shield tiles.

Lol an abrasive layer

If the ablative material is like a thick mattered coating under tiles covering the whole endangered area smearing an outer coat on top of the tiles could give a bonding binding coat that would triple the danger of any tiles being sucked off at re-entry. Extra shaping around flap joints to deflect forces and flow would be logical as a moulded lip up and away at the edges of tiles around body

Maybe we need to rethink re-entry entirely. Maybe a dip down, pull up method would allow the ship to slow down, albeit slower, and then literally drop out of orbit based on a significantly slower re-entry speeds. Imagine if the re-entry took multiple orbits, instead of just one. Thoughts?

@djohannsson8268

Ай бұрын

Apollo used a combination of re-entry techniques, to reduce their re-entry speed. First descending using their ablative shield then attempting to climbing back up without power to reduce speed. This works but takes more re-entry time. Using acs thrusters to change the descent and attack angle.

@yoyo-jc5qg

Ай бұрын

yep i think in the future they'll use the heat generated during descent to power thrusters which slow the vehicle, but like u said it'll take a lot longer to land

I think that, with the Starship's refuel ability, using its rocket engines to retro into the atmosphere, it can be slowed down enough to allow it to return to the surface of the Earth without the use of a heat shield. If it can leave the Earth without the need of a heat shield, it doesn't need it coming back.

Added though to finish firing tiles by reentry itself to save energy the launch site itself could serve as a kiln of sorts to reclaim some of the heat of launch for a productive use even if it is just a finish glaze on commercial tile or brick to be sold for the public. Due to the short firing time and cooling after it would either be a tempered or crackled glaze, suitable for either fireplaces or decorative aged look. Could also create a blackened look with unglazed material absorbing the carbon.

Related but alternate thought. I took ceramics in school and all are produced by heating the raw mixture, normally at least twice to gain final properties. To save energy and to reduce the brittle factor during lift off I wonder if it would be possible to actually use the heat of reentry to give the tiles their final firing. Perhaps in secondary areas, also might send spares equal to double the avg lost to be installed with a spacewalk if needed. Might add partial fired tiles to an upper stage booster that will receive enough heat or as an extra row or two. I don't know the exact specs for the tiles or the mix to make them, I could also see a final glaze layer that finishes on reentry reducing friction with a partial ablative cooling property as well. Like a layer of paint that melts turning part into a glassy surface and releasing evaporative carrier material that melts then evaporates like sweat.

I don't understand why they want to be a ablatable material behind the main tiles. Seems to me the ablatable layer should be external on easily removable mounts that are exchanged on every flight as a routine. Then keep the hard tiles affixed with only slight use on every flight. This method would ensure the ship remains intact with all possible failures. And on the flap joints why not mount the same ablatable material on the joint overlapping but still allowing flats to move free. Then simply remove and replace as a matter of Standard Operating Procedure. Dennis

I would think starship would covered by the same material SR-71 was made of but just on the critical re-entry side of the ship.

Umm the spots where tiles were missing were said to be where a compromise wouldn’t occur per Elon. The ablative material may be bad for reusability but it I think it’s a stop gap measure till Elon can make a more permanent solution

I have no doubt that SpaceX will figure this out. I can’t believe how far they have come already. Is anyone else even close? So excited for the next launch.

Very nice production. Looks like they will have a redundant shield and moving on to the tower landing for the booster... man that's fast. Thought the 09/26 Lunar landing was going to move back to 09/27. Maybe not. V2 is required for reusability and satellite launches (which will Greatly enhance revenue). V3 will be needed for the moon.

The solution to the flat heat tiles is to make each heat tile into an individual dome. The dome will allow the heat to be layered with the hottest temperatures at the top of the dome and the low temperatures where the tile is attached to the skin of the metal. You are welcome.

I suggest the tiles must be given some racks made of metals or alloys which can with stand the temperatures of re-entry and further more increasing the efficacy of the adhesive used initially

Have to correct you one thing. Heat Shields are only necessary for aero breaking. Some might contend that we have the tech to slow down before entering the atmosphere. I don't know if this is true but obviously it is the most cost effective way to slow down now.

SpaceX should strap some solid rocket boosters on the side of Super Heavy for additional thrust.

👍🏾 I hink think oblative heat shield should go in the middle, sandwich between the white thermal mat and the ceramic tiles. The ceramic tiles and the oblative material will need to have some way to move to accommodate the thermal shrinkage and expansion of the steel. So the oblative material must also be cut into tiles. Most likely one will be offset above the other so they overlap and there is no direct path to the softer white thermal mat below.

He did not say the new tiles are twice as insulating, he said twice as strong. It is entirely possible that the new tiles are more conductive, rather than more insulating due to increased density which would be the normal specification for ceramic insulating materials. I think you are misleading people saying the new tiles will tolerate 5200 degrees F. I've never heard of tiles that would handle that temperature. While I'm not a rocket scientist I am a foundry engineer with 50 years of experience so I know a thing or two about refractories.

Re entry from the south/north pole might help.

Despite what the title suggests, the second layer being tested on IFT5 will not address the fins. That will _not_ happen until the Block 2 vehicles arrive. The ablative layer by itself simply will not be able to prevent the fins from being damaged again. It is going to happen again, and SpaceX knows this. Be patient and wait for Block 2 with the fins moved away from the ship's belly.

I’m curious if a “ wrap” can be developed as a heat shield. A wrap would eliminate all EDGES and any other weak spots. Also would eliminate ant TILES falling off. Not sure if it can be created but if it can, Elon Musk can do it.

Natural phenomenon. When one doesn't know the definition of a word that word goes blank. Abrassive "causing friction" Ablative "burns or flakes off with heat or friction" If i were to guess the Misunderstood Word is "ablative" which is why he keeps using another common word instead. Anyone can be found to have many common Misunderstood words. Even college professors. PS: abrasive would cause more friction and thus more heat. BAD. Ablative is used because while it may get hot when it flakes away it takes with it all that extra heat. GOOD.

I have a question. What if there were no flaps? Elon said it best, the best part is no part, I personally feel like significantly more thrusters could control all directional changes. He talked about adding thrusters in the Everyday Astronaut interview. Why not make them more plentiful, powerful, on the back spine of the starships, at about 105 degrees apart, and do away with all the flaps and extra weight, hinges, tiles, motors, batteries I mean, if this could be pulled off it would be a huge win.

Flaps and the whole "belly flop" maneuver is meant to save fuel, compared to other solutions. Starship re-enters at orbital velocities, so a lot of the things that worked for boosters (Falcon and Starship booster) won't necessarily work for Starship. You'd need to burn a lot of fuel just to drop velocity enough to get back to booster re-entry speeds. So flaps/belly flop are how SpaceX saves a lot of re-entry fuel and keeps payload to orbit high.

"Already too heavy?" Musk already addressed this. V2 is slated for 100t capacity and is already under construction. V3 will have 200t capacity and is the version that will land on the moon. The tiles are estimated at 300gm to 1kg each putting their weight to 18 tons at the worst. The throw weight of V2 is 100t including the current set. Making them thicker might add 5 tons... with a 95t cargo capacity as a result in the worst case. From V3, this increases to 200t... so maybe 190t in the worst case. I don't think you did the math. Also, what is the big deal in bringing the fuel up in 6-7 flights?... or 8 for that matter. They have already mastered docking, rapid production of ships, cost effective production of ships and merely need to put up a Slightly modified tanker to act as a Depot. 1 Lander at $300m (Elon estimated standard ships cost $100m), 1 depot at $100m, let's say 8x $20m for 8 reusable tanker flights...($160m). The lander flight might cost - $560m? Compare that to SLS/Orion at $4500m. People keep saying multiple tankers is a bad thing... with no big obstacle to point to. One went on to say "if you lose even One tanker"... what? It would affect nothing. Losing 1 or even 2 tankers would be a hiccup by 09/26 with the massive new factory completed, New engine factory completed, massive new revenue ramping from Starlink... all the pieces are falling into place Well before 09/26. They can build a dozen (reusable) tankers if they want to in the timeframe and budget. In orbit refueling is Critical if we want to send any useful tonnage off world to Actually build a Useful moon base. One that can eventually support itself.

Question: what does a last second abort of an attempted Starship booster catch look like? In the case of the Falcon 9 booster landing on a barge, a last second abort is just crashing into the empty sea. Even if the booster crashes on the barge, no one is at risk. However, if SpaceX is trying to catch a Starship booster on the launch tower and SpaceX has to abort at the last second, what happens? If SpaceX aborts the catch at the last second, the booster is already close to the tower which is close to the tank farm, populated SpaceX buildings, and the tourists watching the launch. In this case, were does the booster (or its pieces if the flight termination system is used) crash? NOTE: The Starship booster does not share any components or even fuel type with the Falcon 9, so the fact that the Falcon 9 has proven reliable has no bearing on the question.

You could say the same about Any rocket launch. Regards the difference: The F9 has a slam landing. The engines produce too much thrust at lowest setting for a Single engine to land (it will take off again), hence the sudden landing. Starship has many engines and can land and Raptor can throttle lower without sputtering. So Starship is in Full Control on landing. If it fails, it hovers out to sea.
