walk-through spacecraft hatch, v1.0

walk-through spacecraft hatch, v1.0

tribolumen
This is a pressure hatch for use in real-world spacecraft and space habitats. I created it for use as an exterior pressure hatch and/or airlock hatch for a Moon/Mars habitat. It is sized as a walk-through hatch, which is to say that a person can open the hatch and walk through as they would a normal door (as opposed to crawling through). Width is 750 mm, which is a bit narrow for a person in an EVA suit (I am finishing a wider model). It includes a small viewing port, hinge mechanism, grip points, and a latch handle. The model includes the hatch in each of the four steps needed to open/close it. Seals, dogs, and additional details are planned for a future version 2. Note that the hatch is quite thick (about 225 mm), much thicker than is needed for the structural layer that withstands the air pressure (which is probably only a few mm of aluminum). Most of the thickness is there to allow for thermal insulation, radiation shielding, the latching mechanism, etc. #airlock #hatch #Mars #Moon #pressure #spacecraft #spaceflight #spaceship #vacuum
