laboratory hasbeen studying asinglesurfaceparagliderfora longtime ago...
It's hereand now complete
plansforthe freestudy,copy,and development!!!
Oneof the first projectsof
the Laboratory,was thegnupwing.The intention wasreally to
createasinglesurface paraglider.Its low coefficient of glide
matter asa mere curiosity,but very funny.
theOzoneXXLitesurprised usthis year...
However,the concept it is
nothing morethan arefinementof the David Barish Sailwing(1965).
With the helpof
my friend CarlesTorres from STRIP-AIR,
we conductedsome initialexperimentsinfull scale.Carlescutand modifiedin his workshop,aconventionalwingto make itasinglesurface.To everyone's surprise..., this wingfliesperfectly!And onlyused 4anchors perrib.The firstglideswere made in theschool rampin OrganyÓ(Catalan Pyrenees).Othersmallruns andglidesin my training areain
TeiÓ. Thebrake pressureis low.The ease ofinflation isamazing, supereasy!,even withoutwind. Theinflation withwind is"explosive", andmust beundertaken with caution.

Basedon previous experience, duringnovember 2011 Iworked in modifications onLEparaglidingprogramto allowdesign forsimpleparaglider surface.The most difficult thinghas beenget theproper rotationsin spaceof the loadtriangles, tobe
the direction ofthe lines. Finallyachieved, andthe plans of a modelidentical in geometry to
theBarretinabutinsimplesurface, is included here. The first
prototype ofBarretinaHyperlite, is currently beingbuilt bymy friends atAdrenalineParaglidersheadquarters
inYecla(southeast ofSpain).Is very closeto complete (in january 2012). The gliderwillbe renamedand decoratedwith the colors ofAdrenaline, butit is arealBarretinaHyperLite! The job oftuningthe Adrenaline prototype,
will enable us adjust
thebetter trim speed.It is expecteda new set ofonly three risers per side. The great work,
andtime, invested inthis prototypebyAdrenalineParagliders, are beinghelpful tothe projectBarretinaHyperLiteandthe overall developmentof the concept of simple surface paragliders.Thesimplesurfaceglider,with the plansfreely
available in public domain forstudy, and arealmodelsoon in flight...
Stability and collapse resistance of the simple skin paragliders
certainly looks pretty small, acording previous experiences. Then,
the advantages would be the light weight/volume and ease of
Keep inmind thatthis is anexperimentalprototype,
currently under development.The reactions ofthis wingcan be potentially dangerous,
andis (actually) not certified.
Note about DXF format.
Note,September2013:I am awarethatopenand printDXFfiles, itisnot easy fornon-specialistsin CAD.SoI ampreparing acollection ofPDFsforprintingin A4 or A3 format andfacilitate thework, to potentialbuilders.
