Building the fuselage

Airbus A320 -3D view

Since we have to start with something, why not the fuselage?
The fuselage is made of two halves sheeted with 15/10 mm balsa. Once completed these two halves are glued together to form the airframe.
This method is very efficient and let you build very impressive airframes. It is also particularly adapted for rounded bodies like this A320 we're about to build.
Building the fuselage using this method is not difficult as long as you are patient and careful with your work.
Don't forget that you need to build two symetrical parts! Like for the wings ;-)

 

Cutting the parts

Milling the parts

Découpe des pièces en CN

 


First you have to cut all the parts needed to build the fuselage. Depron foam is used for the ribs. It's light and economical.
Once again the CNC milling table proves its efficiency. But if you don't have one, you can cut the parts with a jigsaw.
You only need a bit more time and patience.


Buidling the first halve

Plan fuselage A320

1. The side view is printed and taped on the table. Of course you will need to print a left view and it symetrical right view for the other half fuselage.

Center reinforcement fuselage A320

2. We now place the "spine" on the drawing. This will help us to properly position the ribs.
This part is made of 30/10 balsa and will give the plane its longitudinal strength.

3. We now place the balsa spars that outline the shape of the fuselage and then the 2 front and rear ribs made of 30/10 balsa.


Gluing the ribs

4. Next we glue the depron ribs. A triangle is used to check their position.


Don't forget the balsa doubling at the center of the fuselage where the wing will come.


sheeting the fuselage with 15/10 balsa5. When the airframe is built whe can sheet it using 15/10 balsa.


NOTE. The junction between the fuselage and the wings can be unrolled. The construction drawings show the outline of this part for a better precision.
Other parts of the fuselage that can be unrolled are sheeted with larger balsa plates. The bottom and the nose are covered using narrower planks to follow the curvature of the fuselage. It's the same technique as for a boat hull. It's not difficult but you will need patience and precision to achieve a good result.



Cutting the hatch to access the battery pack6. When the half hull is built we cut the hatch for battery access.I've positionned the hatch on the right side, more or less where there is a cargo door on the real one. But you can make it on the left side if you prefer. It wont change anything to the construction.

Battery pack floor7. The floor that will support the battery pack is now glued in place. Some balas spars are added to reinforce the airframe.
It is also time to cut the hole for the nose gear and install it. If you want to use retracts it is time to install them.


8.When the first half is done. Just start over from point one to build the other one. Dont forget to make a left and a right one!
