There are many advantages to this vortex generator STOL kit for homebuilt aircraft:
- 1) increased lift,
- 2) slower stall speed by 4 to 6 MPH,
- 3) shorter landing distances,
- 4) shorter takeoff distances,
- 5) higher angle of climb,
- 6) tighter turns,
- 7) gentler stalls,
- 8) better aileron authority at slow speed,
- 9) aircraft is more controllable at slow speed,
- 10) in general increased total performance and safety.
The kit comes with clearly written installations instructions that allow you to determine where on the aircraft, especially on the wings, to install the vortex generators based on empirical data to get the benefits described above.
The installation instructions also gives tips on other suggested locations to place vortex generators that may well cut down on the drag of the airplane thus increasing the aircraft’s speed and reducing fuel consumption. It also includes the number of vortex generators (VG’s) listed in the table below for the kit selected. Plus a 3M very high bond adhesive tape to apply the vortex generators to the aircraft.
The deluxe generic vortelator kit 261-AD1 contains enough vortex generators to do most homebuilt aircraft wings and if necessary the underside of the horizontal tail. In the case of an exceptionally large homebuilt aircraft or a biplane additional vortex generators may be required and can be purchased 25 at a time in kit 261H.
The vortex generator kits that Aircraft Development has specifically flight tested and developed kits for contain the number of vortex generators dictated through flight test plus extra vortex generators for spares or to do some experimenting on your own.
The vortex generators are precision injected molded and made from UV stabilized clear polycarbonate material. This material is extremely strong and lightweight. 100 vortex generators will weigh approximately 1 ounce. The bottom of the vortex generator has a slight curve to match the wings airfoil. This feature allows the vortex generator to better adhere to the wing as opposed to the flat bottomed vortex generator made from extruded aluminum. These vortex generators have a full sweeping sail which wind tunnel testing has shown is superior to the vortex generators that have a steeper sweeping sail with a flat top.
