  • Airmat  "Airmat material consists of two layers of fabric connected by continuous tie yarns dropped from one layer of fabric to the other during weaving. By varying the length of the tie yarns flat panels of various thickness could then be made."  
    
    "Realizing the possibilities of this material Goodyear Aircraft Corporation (GAC) made a sample airfoil Airmat sections and tested it both statically and in a wind tunnel in 1952."
• Inflatoplane
• In circa 1871 in a kite patent we find  Isaac Ferris rehearsing connectors between the two surfaces of an inflated airfoiled wing. Discussion regarding this:  HERE.

  • [ ] Inflatoplane group, joining request is pending. Jan. 24, 2013.  Their message are open only to members. "This group is now the premiere source of Inflatoplane pictures and technical information on the web. Although there will be historical information to be found here on the project the main focus here is to gather and analyze the technical documentation."
