The Airtight Hangar Door is a telescopic Large Grid-only block that extends from its standard size of 1x1x1 block to 3x1x1 blocks. Once closed, it seals an enclosed airtight room that can be pressurized using Air Vents. It is used, for example, in the construction of doors that can let through objects larger than a walking engineer — typically Small Ships.
Their advantage is that they count as the same grid as the main grid and do not have the typical subgrid issues of larger, custom-build mechanical doors. Their limitation is that the smallest side of the passing object can be at most 4 large-grid blocks = 10 meters high (it can be wider and longer than 10 meters though).
One airtight hangar door block can seal 1x1x3 of space.
Usage[]
The block's functionality and user interface are identical to the Door.
To place a Airtight Hangar Door, you need 1x1x3 blocks of free space. Airtight Hangar Doors take ten seconds to open or close.
- When "open", it only occupies a 1x1x1 block volume.
- When "closed", the block extends outwards for a total of 1x1x3 blocks. If a closed Airtight Hangar Door block touches another block of the same grid, they form a temporary seal and count as one grid.
Tip: In the main ship/station's Control Panel Screen, select all Airtight Hangar Doors that belong to one door and create a group for them. Then assign the group's Open and Close actions to your Tool Bar or in a Timer Block to trigger them.
Example Applications[]
A single Airtight Hangar Door can be placed as protective cover over individual fixed weapons or over small thrusters. More commonly, you build a row of Airtight Hangar Doors to create large seamless doors of unlimited length and up to 10 metres height:
The basic 1x1x3 arrangement allows for a maximum length of 5 meters per Airtight Hangar Door block. Two Airtight Hangar Doors put opposite of each other yield a sealable 10 meter length door. And series of such opposite pairs creates a 10 meters high door of any length.
Suggested solo applications are as sliding doors to cover fixed weapons, thrusters, windows, interior turrets, etc.
A single airtight hangar door can also be used as protective cover of ship components.
Alternatives[]
You can build any size blast doors using various combinations of Blast Door blocks and mechanical blocks such as Pistons, but the use of pistons forms separate subgrids which are, even once closed, not airtight. Which may be acceptable for certain large ship hangars.
For larger craft, elaborate solutions have been produced to build larger airtight door assembly. You can build folding doors of any size on hinges or on rotors, that can seal the room using Merge Blocks, if you build the edges out of slender blocks such as Blast Doors. But the fact that you cannot merge a subgrid back onto its own main grid, and the task of finding the right rotor head dislocation for the seal, makes these builds a bit fiddly.
