APR Performance AS-206703 APR Adjustable Wings - GT-250 Series
GT-250 Adjustable Wing
All GT Series wings feature an all-new, low-drag,
aerodynamic 2D designed airfoil shape. The 2D design allows the
wing to maintain a consistent level of downforce across its entire
span. Computational Fluid Dynamics (CFD) analysis was
performed on this wing to support validation of its aerodynamic
design. Click here to see the CFD data.
Each GT Series airfoil is composed of lightweight
and durable carbon fiber reinforced polymer (CFRP)
composite materials. These airfoils contain pre-pregnated woven
carbon fiber sheets for superior strength and low weight. All
CFRP airfoils are made using pre-pregnated composite
manufacturing processes (i.e. high-temperature autoclave and vacuum
bagging) in high-quality aluminum billet molds.
Supporting the airfoils are 10mm aircraft grade 6061 billet
aluminum pedestals that come in a flat black powder coat
Gurney flaps are included and pre-installed with every
GT-250 wing. These are super lightweight, made using
pre-pregnated carbon fiber processes.
The Gurney flap (a.k.a. wickerbill) is an aerodynamic device
that was originally pioneered and developed in the 1970s by a
racing driver named Dan Gurney. Unbeknownst to his competition,
this device was used to increase downforce while minimizing
increase in drag. He found that not only did this device increase
the lift/drag (L/D) ratios, it also increased the stalling angles
(so he could operate the airfoils at greater pitch angles). It took
a few years for everyone else to catch on to its purpose, and now,
the Gurney flap (or similar device) can be seen in race cars and
even airplanes all over the world.
