HPR X Wing - T70

Postby SpaceManMat » Tue Nov 21, 2017 10:42 pm

So as promised I’m kicking off another Starwars themed build. I’ve decided this time to build the T70 model X-Wing as seen in the force awakes. It varies from the original X Wing in the engine design and outer wings. This will be approximately double the size of the previous scratch built X Wing, about 1.2m long. In keeping with the size doubling it will also use a single 38mm motor, I’m aiming to be able to typically fly G or H motors. I’m not sure about the motors on the wings, I might end up fitting it out for 18mm motors, but they will be mostly for display purposes (not capable of actually lifting the X Wing).

So here’s a reminder of what I’m trying to achieve. Note the T70 has the engines that seperate when the wings are apart.

What does show well in the above picture is that the T70 wings have different shapes for the top and bottom.

Here’s the design I have in OpenRocket. One of the limitations of OR is that the tubes fins (ie engines) must attach to the body so they look a little weird here, but it gives me confidence that the thing will fly. I’ll be leaving the engine open in the middle so it acts like a tube fin rather than trying to ram the air down into the smaller tube, it should look reasonably similar while not wrecking the aerodynamics.

I’ve just about finalised the requirements for getting laser cutting done. One thing I did want to do was to remove some of the material in the internal bulk heads to bring down the weight a bit. Below is the design in excel, the red cross represents the 42mm hole that the internal tube runs through. So I need to keep material around the tube and also around the perimeter as well as spokes that join the two together. Anyone have a recommendation as to how this should be done?

Picked up a bunch of parts from Aus Rocketry during the QRS Christmas launch, thanks Blake.

The 98mm tube will be cut up and used for the engine intake In case your wondering.

The 38mm tube will form the main (internal) tube running the length of the body, I’ve ordered an additional piece of 38mm tube for the nose.

Did a layout of the pieces to get a basic feel of the size and shape. It’s going to be a beast of thing.

I don't know how I missed this before, looks like it will be awesome. Really nice size, that's going to have some serious presence when it's done!
