Fluid cooled pressure garment

DETAILED DESCRIPTION The present disclosure describes an improved fluid cooled pressure (anti-G) garment that can effectively reduce disadvantages inherent in currently used garments for example the thermal burden, cockpit interference, sizing adjustment, and/or maintenance and repair issues.
The main objective of the present invention is to provide an active means of cooling wearer of a pressure garment such as anti-G suits worn by aircrew members of high performance, high altitude aircraft.
A secondary objective is to further reduce the passive thermal burden due to excessive bulk in the garment system.
Broadly the present invention relates to a pressure garment particularly suited for use as an anti-G suit comprising an inner layer facing towards a wearer and an outer layer, said inner and outer layers being connected together to form an air pressure holding bladder, means providing at least one area made from air impermeable, water vapor permeable material defining a first passage means for water vapor through said inner layer and means defining at least one other area made from air and water vapor permeable material defining a second passage means for air and water vapor through said inner layer.
Preferably, said bladder is received within a pocket form between an external restraint layer and an inner lining layer positioned adjacent to said inner layer of said bladder, said external restraint layer being formed a material to limit expansion of said bladder under inflated condition.
Preferably pass throughs are provided through said inner lining through which said bladder may be inserted into said pocket.
Preferably, garment further includes releasable connector means connecting said bladder inside said pocket.
Preferably said outer layer is also provided with at least one area formed from of air and liquid impermeable, water vapor permeable material to provide some of said first passage means through said outer layer.
Preferably said inner and outer layers are made from air impermeable, water vapor permeable material that forms said first passage means
