Most photos of rocket belts show insulation on the hot gas tubes. It typically looks like fiberglass wrapped with heavy foil. What was used on the Bell packs?

Great. Is the insulation only serving to keep heat off of the
operator or is it also keeping the combustion products hotter until
the gas exits the nozzle?
Do you think a thick fiberglass would work well in this application?

Its mainly for keeping the heat.
The steam is some 1400 F / 725 Celsius, so the downtubes are pretty the same temp.
Don't know the burning temp of fiberglass, but stick to the old principle, or use a aluminium cover
But hey, there are a lot of builders on this group, they know it better than me :-)

Yeah I don't think fibreglass is the answer.I maybe wrong but that is not a high temp material in any form.

In my own defence. that isn't glass fibre. Its a compound wound bespoke thermal material. But yes use that. I don't know what they used back in th '60s but it wasn't fibreglass. What you have found is more than adequate for RB applications. If you can wrap that S~!) round a turbo then you can definitely wrap it round jet pipes.

Bobby Clark Jan 23, 2009, 2:22 PM to Rocket_Belt I also saw this product. It should be available now and would save on the foil step. Is is also washable. Same site under the automotive heading. www.heatshieldproducts.com/hp_armor.php Some of the other products come in colors if desired. |
