Hi guys,
I have a project I want to work on. It is going to be a glider, based on the FT Simple Soarer designs. However, I'm going to remove the dihedral and polyhedral, and add ailerons and flaps. Hence: "advanced" soarer. Also, it's going to be bigger, so it can handle more payload (FPV gear, laaaaarge battery, and pixhawk autopilot).
The reason to take the 150% value is that the wing will consist of 3 foam sheet lengths. That results in a wing span of 2.2 meters, or 7.3 foot. The plan is to have a middle section, which may be glued to the fuselage, and 2 removable outer sections. I plan to use Josh B's method of wing joining as he and David show in the monster plane build video.
Here is a picture of printed plans with my own dimensions (in centimeters):
Annnd while designing this on paper, I run into the first thing I'm wondering. I intend to use the entire trailing edge of the wing for control surface, but how much of that should I use for aileron, and how much for flap? I want to be able to use the 'crow' mode (flaps down, ailerons up) for braking when I come in for a landing. The easiest would be 70% aileron, and 30% flap, because that's where the foam board joins... But is that useful or should I shoot for something different? It's possible to make the ailerons smaller and the flaps bigger, which will result in a larger middle wing section.
I'm going to use this thread as a build log, and questions about what I want to do will come along as I build, and I'll keep you guys updated, with pictures and a maiden video (at some point... ). I'll also keep this first post updated.
Update 1
Sorry for the wait guys, kinda busy and stuff. The wing is nearly completed, and consists of 3 pieces which will be detachable for transport. I've made the servos removable, so in case of a crash it's possible to replace them. Flaps and ailerons are all 42 cm long, there are undercambered wing tips. The spar is made of basswood. I reinforced the spar area with fiberglass also.
As you can see here, I had to move the servos closer to the spar, otherwise I couldn't make the flat bottom fit...
The spars are interlaced, and there is a screw holding the outer part of the wing on. Initially I also wanted to screw the 2 spars of the middle section to the outer part, but I think it's way overkill (and a lot of work).
