Vortex Generator Install on Aerolite 103!
Вставка
- Опубліковано 7 вер 2024
- I recently installed some Airwave Vortex Generators on my Aerolite Bush Plane. It was a pretty easy install and I am so far very satisfied with the results! The template I used to space the VG's in the video does not come with the VG's, I 3d printed it. This made the install super fast, and very easy.

Placing the VGs on the Wing
Starting 50mm (2”) from each wing tip:
Remove the backing from the adhesive on a VG.
Set the first VG in a notch of the 60mm template.
Carefully touch the very tip of the VG to the wing surface right behind the line.
Guided by the angle of the template, lightly set the base of the VG onto the wing surface.
Double check the alignment, and if correct, press the VG firmly onto the surface.
Rub each side of the base firmly with thumbnail or a popsicle stick to press out any air bubbles.
With the template secured by the first VG, use the remaining notches to set two more VGs in place.
Move the template so that the third notch is secured by the last VG already set, and set two more.
Continue to place 15 VGs at the 60mm spacing = 900mm (3ft) from the wingtip.
(This closer spacing near the wingtip is to ensure that the tip does not stall first.)
Do the remaining portion of the wing with the 90mm spacing template.
120 VGs is enough to do 9.9 metres (32 ft) of wing at this spacing.
If a VG happens to land on a rivet or a seam, displace it just enough to miss the obstacle, then continue the regular spacing.
Placing VGs on the Horizontal Stabilizer
Stretch a line on the underside of the horizontal stabilizer, 100mm (4”) in front of the gap between the stab and the elevator.
Using the 30mm spacing template, set a row of VGs with the front tips along that line, starting from the outside.
If the surface of the horizontal stabilizer is flat, the curved base of the VG will contact only at he tip and the heel. Rub the VG on a piece of sandpaper laid on a flat surface to adjust. Don't try to completely flatten the base - just make flat areas at the tip and heel, the adhesive will do the rest.
Placing VGs on the Vertical Fin
Stretch a line on the vertical fin 100mm (4") in front of the gap between the fin and the rudder.
Using 30mm spacing template, set a row of VGs with front tips along that line.
The hinge line will likely be swept back, so orient the template each time so that all the VGs are oriented with the front tips about 5º upward to the horizontal, instead of alternating. This way all the VGs will be near the optimum 15º when the aircraft is nose high at landing and take-off when the rudder effect is most needed.
Of course, do both sides of the fin.
I just followed the manufacturers recommendations. 3rd set I've installed with excellent results.
@@kidkhaos6427 what was the power off stall speed before and after
@@kidkhaos6427 if you put them too far back they do nothing ua-cam.com/video/aoM2YQBHuV4/v-deo.htmlsi=H6dlMHsw7Nt7Y125
I used a ladder and a laser level and a protractor
I'm not fancy enough to have lasers! 😅
I couldn't find my protractor so the next best thing was CAD + 3D printer
@@kidkhaos6427 we did manage to get the same set tho. Did you put em under the horizontal stabilizer?
@@jamesordwayultralightpilot not yet, but I plan to after a little more reading up on the topic. I have a whole pile of them left.
@@kidkhaos6427 it basically makes the tail stall at low speeds too so you don't have a wing that can fly slow and a tail that mushes out at normal stall speeds.
I would like to know what effect thses had on the proformance of the plane I am a big fan of vortex generators on light sport and most small GA planes but have so little info on ultra lites. any into would be apprciated.
I really like them. There is a very apparent gain in control authority at low speeds, and slightly lower stall.
Hi - Did you do a performance comparison?
No, but my stall speed is about 2 mph lower, and low speed handling is drastically improved. I wouldn't bother flying without them anymore. They are cheap and unbelievably effective.
