Neither of those would have any difference. And why doesn't flying heads up even matter?Having LFBs and flying heads up would have been better.
No.Many have heard of the insulating and fire resistant abilities of Starlite but could it have reduced or eliminated the icy foam build up that lead to the destruction of the Columbia?
Could it be theoretically possible to create an insulating material that would prevent the build up of ice as a hazard?No.
a. the capabilities and characteristics of "Starlite" are not defined enough to make a judgement.
B. The foam on the tank was insulation to maintain the propellants in a cryogenic state. It isn't a heat shield. That wasn't demonstrated for Starlite
C. If Starlite were to replace the tiles on the orbiter, it would have to weigh the same or less. But it wasn't the tiles, it was the RCC on the wing leading edge. No demonstration of that type of structure was done.

There was no "icy" foam. It was just foam.Many have heard of the insulating and fire resistant abilities of Starlite but could it have reduced or eliminated the icy foam build up that lead to the destruction of the Columbia?
There already was. It was the existing foam that was on the External tank. That is what it was for, keep the propellant cold and keep ice of the exerior. And it did the job well. The only issue was joints and protuberances. The foam sheds. The issue is that the Orbiter tiles are not impact resistant. Almost all launch vehicle (especially ones using cryogenic propellants) create a debris shedding environment during ascent. This is not usually an issue. The problem arises with vehicles that have parallel stages or configurations with hardware next to a shedding environment.Could it be theoretically possible to create an insulating material that would prevent the build up of ice as a hazard?
If it was possible at the time.In theory, sure. Of course, no such material is known to exist (with suitable thermal characteristics, weight, durability, etc.) or NASA would have used it.
Aerogel is too frail for such tasksI wonder if starlite could be made to flow through aerogel tubes.
In terms of transpiration cooling...has anyone looked at the heated working fluid doing a chemical reaction with another fluid so as to lose heat before a fresh circulation?
Lastly...say I want a sample return coming in very fast.
Any work done with ablative coatings on shuttle tiles?
Better yet be using Titanium for the frame which would allow use of a less insulating but structurally stronger material be used in place of the Carbon Carbon tiles.Aerogel is too frail for such tasks
no need for ablative coatings on shuttle tiles, just make the tiles thicker
No, just stick with one and make it thicker. No advantage to use different layers.Tiles and ablatives in combination might be good for outer solar system sample return. I imagine they would could come in so fast you might want a combination.
Not even with respect to mass savings for high delta-v missions? Everything's a requirements/design/cost/performance tradeoff in aerospace.No, just stick with one and make it thicker. No advantage to use different layers.
I was Maurice's initial contact point at McDonnell Douglas in connection with the JAST program, but management of the overall Starlite effort was handled by someone a bit higher up in our management chain. Unfortunately that manager disliked Maurice intently. I can remember one visit that Maurice made with his daughter and how verbally abusive our manager was to him, with her sitting right there. Our manager was bizarrely determined to discredit Starlite. Somewhere in my files I may still have the memo that he circulated to the upper management responsible for advanced technology development in general, where he recommended that we drop Starlite and go instead with something like this Aircrete stuff. The problem with that, though, was that the material he was pushing was "cementitious" I think was the word; much heavier for a given thickness than Starlite, and couldn't be made flexible or be incorporated into plastics or foams, both of which Starlite not only could be, but which it had been for the initial series of tests that we ran with it. The "cementitious" materials have much more limited applications in that regard.Similar to Starlite?
too heavyFor aerospace use, I wonder if Starlite and a binding agent could actually use a first re-entry to set the product somehow. Pour between two layers.
Starlite wasn't a "thing" - it was a family of things. When Maurice made his first visit here, he was upset because his suitcase had obviously been tampered with either at the loading or unloading end of his flight. I went with him up to his hotel room and watched him unpack what he'd brought. He had the famous tile that had been exposed to the nuclear flash simulator, another that he'd used frequently in demonstrations at ICI and BAe, and some basic materials in jars that he was going to mix up for a batch here. His way of working during our evaluation activities was that we'd tell him what kind of physical and thermal environment there was for a specific part we needed to protect - mostly JAST at first, then broadening out to other aircraft at other sites. He'd go off into the lab we'd provided for him (to which he insisted on having the only key) and mix up a batch that he thought would do that specific job. He'd coat the panels (more on that in a minute) and when they were ready he'd hand them over to us for testing. Based on the results of those first tests, he'd go back into the lab and refine the formulation, and we'd test again.My impression is, that Starlite was not mechanically very strong. I doubt it would have stayed in place when the air is rushing with high mach numbers.
In the video from the BBC, it was emphasiest, that it could widthstand the thermal blast of a nuclear explosion (that's heat ray) but it was never claimed it could widthstand the following air pressure blast.
Interesting.So think of Starlite as you'd think of "epoxy" for example. It was a basic material that could be reformulated as required to gain necessary physical and chemical properties. I've seen it as foam, plastic, and coating.
In order: I can only repeat what Maurice told me himself, that the hairdresser story was to mislead people. It was true that he'd done that, but it wasn't where Starlite began. I've seen the raw ingredients for the coating type of Starlite, and my ex-wife of 20 years was a hairdresser herself, so I know those chemicals weren't related.While some might have attacked the maker’s background as a hairdresser (outsiders have a place)—that gives researchers a starting point.
What kind of products, trade publications existed around the time of the invention? Did he ever work with hair-relaxers needed for thicker hair? If so the secret for Starlite might be found in the pages of EBONY or Jet.
What goes in the blue water?
Does the estate have a client list or other ephemera?
Were NASA folks his main customers?
Lots of rabbit holes for folks to take a Will Graham approach…shades of MANHUNTER.
An individual who puts himself in the inventor’s place might rediscover some secrets.
better than government culture.That's another reason I hate corporate culture.
I don't know exactly who Maurice had approached. Well, hang on, I do know a few. He had almost come to some sort of partnership (he said) with ICI (the UK chemical giant) but as I recall there was a problem because he wanted 51% of the business and they weren't ready to cede him so much control for an unproved product. There was BAe of course. It was one of their people, on our JAST/JSF first phase team, who knew Maurice and put me in contact with him in the first place. But Maurice told me, I believe in our very first phone call, that somebody there had violated the confidentiality agreement they'd signed and at least one person had stolen some samples and left BAe to form his own company, which didn't go anywhere because he couldn't figure out how to make more of it. Then there was Kaiser, fronting for the US Navy, which also ended badly. He mentioned Boeing (pre-merger, when I was working at what was still McDonnell Douglas) as well as Pratt & Whitney. But I'm sure there were others that I've either forgotten or never heard about.I know oil derricks have this:

Any attempt to do business with the oil and gas sector, Steve?
