Thermy 4: Planning the Fuselage

After drafting a first version of the nose, there’s work to do on the fuselage. So this week, it’s going to be a lot of frames to draw.

Joyrider: Taking Stock

Since the Maiden Flight during Summer last year, the Joyrider has spent about one and a half hours in the air, while spending up to eight hours in the workshop and the rest of the time on shelf. It has been a rough ride, with many setbacks. However there’s a happy ending. Today, I’d like to take stock of what happened since the first flight tests.

Thermy 4: Planning the Nose

Based on the design variations, I’m moving on to the actual planning and start to blueprint the nose. If possible, it is supposed to give the aircraft a semiscale appearance and that means I basically have to start from scratch.

In order to create parts repetitively and precisely, the blueprinting is going to be computer-assisted. In theory I could draw on paper, scan the diagrams and print them. However, I would lack the 3D preview and applying adjustments is going to be much more time-consuming.

Joyrider: Last Details

By finishing the linkage the out-fitting has come to and end an I can take care of the last details. Those cover two areas: the fuselage and the wings.

The fuselage needs a couple of maintenance hatches in order to easily gain access to the drive unit, and the tailplane’s servos and fixture. The fuselages’ belly needs to get reinforced, too. And last but not least I’d like to add some details to the nose.

The wings need an additional strutting in order to stabilize the lower wings. And it will surely add to the good looks.

Joyrider: Nose

After framing the fuselage, the nose had to be tackled. This was the first time my skills got stretched to their limits and I had to rebuild repeatedly.

The main challenge was the quite accentuated curve that I expected the stringers to follow. I did manage to bend them accordingly on the fuselage’s halves while they were fixed to the construction board and the fixtures seemed to be stable. However, while trying to join the two halves I overtaxed the wood glue.
