DESCRIPTION

Spanning 74 inches, the GTC-500 Carbon Fiber Adjustable Wing is the largest wing available in APR's catalog. With its optimized 3D airfoil shape, the GTC-500 is perfect for high speed touring applications and supplies an ample amount of downforce without causing excess drag. All GTC Series wings feature an aerodynamic 3D designed airfoil shape to obtain the optimal balance of downforce. This design allows for a reduction in drag, yet maintains an ideal level of downforce. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support validation of its aerodynamic design.

Each GTC 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 finish.

APR Performance Features:

  • Factory-like fitment: This vehicle-specific component is designed to match the contours of the vehicle's rear deck area, for a factory-like fitment.
  • Carbon Fiber Construction: This component is formed in the autoclave at high temperatures using pre-pregnated carbon fiber manufacturing processes, for high strength and low weight.
  • UV Resistant Coating: finished with UV-resistant clear-coat paint for resistance against various environmental conditions (take care of this as you would take care of your vehicle's paint finish - polish then coat with good-quality wax or synthetic protectant).
  • Mounting Hardware Included

OVERVIEW

Spanning 71 inches over its optimized 3D airfoil shape, the APR Performance GTC-500 Adjustable Wing supplies maximum downforce in widebody sports and touring car applications.

CFD DATA FOR GTC-500: 

OVERVIEW

Contained herein are the data and results of the Computational Fluid Dynamics (CFD) analysis that was conducted on the GTC-500 airfoil. This data illustrates how the airfoil performs in different conditions by comparing Downforce vs. Angle-of-Attack (AOA) vs. Speed, and Drag vs. AOA vs. Speed. This data will provide insight with regards to how and how much the airfoil performs with respect to these conditions.

To learn how to interpret and apply this type of CFD data, see sample analysis on the GTC-300 page.

CFD DATA (TABLES)

The following table shows the actual data that were collected from the CFD analysis. The numbers in the table are represented in Pounds.

The following image illustrates where and how the AOA is referenced. At 0 degrees AOA, the reference plane is parallel to the direction of the free air stream (the stream would travel from right-to-left in this image). This reference plane can be simulated by placing a ruler across the top of the center section of an actual airfoil.

CFD DATA (GRAPHS)

The following graph illustrates the effects that air speed and AOA have on downforce only. The higher the air speed and AOA are, the higher the resultant downforce is.

The following graph illustrates the effects that air speed and AOA have on drag only. The higher the air speed and AOA are, the higher the resultant drag is.

Gurney Flaps

Gurney flaps are available for all APR Performance GTC Series (200/300/500) wings. These are super lightweight, made using pre-preg carbon fiber processes, and conform perfectly to the contours of the GTC series 3D airfoils. They are easily attached using the included double-sided tape.

HISTORY OF THE GURNEY FLAP: 

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.
