Hey gang, for many years i've been fascinated by the lifting body fuselage designs by Burnelli, and I've recently decided to give it a crack at building one of them. I'm going to be making the Burnelli UB-14.
This is what Its hopefully going to look like
I made some thin strips of foam to design the aerofoil for the fuselage, took a couple of goes until i was happy. The plan is to have the fuselage 20cm wide, and as long as i could get it with 30 inches of foamboard.
I then cut my plans out, the fuselage sides fold up using an A style fold like the ones flitetest uses (or is it a B style...)
I then covered the outside of the fuselage in packing tape, I should have done this first. oops
Started glueing the sides up and bending the foam.
It was tough getting it glued in one go, but I managed. and I present to you the start of my fuselage.
After a lot of playing with numbers and sizes i came up with a shape for my wing, its going to be tapered, but not nearly as tapered as the real one. my tip chord is almost twice what it is ment to be. i figured the extra wing area cant hurt the wing dimensions are 20cm root chord, 10cm tip chord and 40cm length per wing. I made a template which helped me draw it onto the foam
The wings drawn onto the foam. On top of my dimensions above i added some ailerons and flaps, the depth of which is that of my ruler, so just over 1 inch
My wing pannels cut out and taped on the other side
The next steps are to get some tube and some dowel rods. my plan is to have the wings removable, for easy transport. i plan to mount a carbon tube inside the fuselage and have wooden dowels in the wings which can plug into the tube. (unless you guys have a much better idea for me.
Then I'll build the tail booms and the rest of the tail. I plan to cut out two notches out of the nose of the fuselage so i can mount some wooden motor mounts. Any advice is appreciated. as this is my first plane where i'm really just working it out as I go
