How reliable is this information?
Just out of curiosity, do we know if the honeycomb method worked before it was deemed too labor intensive? Because I'm told that using this block method results in chunks blowing out.
I'm also having a problem with this set-up: Apollo is at the upper size limit for avcoat; Orion is way bigger; use avcoat.
Reading a real front-fell-off aura from this project. It makes me wonder if spending 6% of GDP to develop and run a crewed lunar program 60 years ago and then immediately destroying the evidence, r&d artifacts, and materials fab capabilities was a good idea.
Apparently, it worked too well in Lockheed Martin opinion.
>Temperatures on re-entry “were lower than we expected” on EFT-1, Hawes told reporters here during Lockheed Martin’s annual media day.
>That data supports a Lockheed Martin proposal to scrap the current heat-shield design, which features a 5-meter-diameter honeycombed frame, in favor of an alternative composed of rectangular heat-resistant tiles glued together with a silicone-based adhesive, Hawes said.
