Armadillo Aerospace News: 63" Bulkhead, Custom boards, Engine work
The custom honeycomb bulkhead for the next vehicle arrived, and we have started prepping it. The current cabin has a 40” diameter bulkhead midway up the cone with a fairly sparse 2” thick aluminum honeycomb core. We have pressurized the cabin to 18 psi without any problems. The new bulkhead will be going on the bottom of the next vehicle, and is a full 63” diameter, so it needs to be stronger to compensate for the larger span.
