Description

Since this stuff has come up over the past decade, I may as well record it for posterity. The pressure garment on the left is based roughly on the MIT Biosuit after having overtechnology applied to it to reduce the need for personal tailoring from the ground up and to include both hands and feet in the system. It applies mechanical pressure to combat depressurization and the neck seal has a balloon-like pull-over hood that inflates into a passable bubble helmet. The ribbing on the sides contains oxygen and waste recycling gear, and the codpiece both prevents the need to apply mechanical pressure to delicate bits as well as acts as the entry point to the sanitation subsystem (the codpiece is also easily openable to allow latrine use). Everything is connected by flexible tubing that runs up the spine (not shown). A gel inner layer fills any voids left unfilled by compression.

The suit's mechanical compression also makes it function as an anti-g-suit. At its fail-safe non-powered condition its mechanical compression it is sufficient to protect the user from hard vacuum and offer mild anti-g protection, but this compression does increase the risk of redout under normal conditions, especially under strenuous activity. The materials used are therefore dual-phase elastics that expand (or, more accurately, loosen) under alternating electric impulse of one phase and contract under alternating electric impulse of another phase, automatically adjusting the suit's compression to fit externally detected pressure and acceleration conditions as per the systems in the ribs. The suit nominally maintains a low loosening signal to make it merely skintight rather than stifling to wear. The pressure garment can act alone as a spacesuit but is less-than-preferred due to an overall lack of protection (the hood in particular is relatively prone to puncture). It is thus generally used as a pressure suit underneath armor, 'proper' spacesuits, or shirt-sleeves uniforms when depressurization is a reasonable risk.

Hence the flight suit on the right. It is a one-piece variation on the combat uniform with smooth pockets rather than patch pockets to reduce snagging risks. The flight helmet has a neck seal that mates around the neck seal on the undersuit, thus providing a hard, atmospherically pressurized helmet for the wearer's head. The bug-eyed visor is automatically, electrically tinted and acts as a backing for helmet-mounted display projectors. Air valves on the front and back of the helmet provide connections to external air supplies. The back one is usually connected to backpack or hip life support while the front one is reserved for buddy air. To maintain a pressure seal, the hard mask in front must be latched closed and the visor must be lowered and latched. Both can be opened for comfort.

The flight suit shown above omits for clarity typical additional flight gear such as vests with additional pockets, parachutes, or life support systems.

Your uniforms diagrams with these excellent, detailed descriptions are awesome to see! Are you still making them?
