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!

Looks great Mat! Looks like it will be a real showpiece when it is done :D

Been far too busy lately, so thought I should get back to this project.

I’ve cut the main engine intakes from 98mm tube as follows
Image
Engines Construction

Front on the engines will appear as follows

Engine edge on

Note that I intend to keep the back open. If I was to close it, it would cause huge drag and id loose the advantage of what are effectively tube fins.

From the side on (as viewed from the pad) this won’t be noticeable. Although the shape will be a little different, the overall look is pretty good.

I’ve also started assembly of the rear body, settleded on just using a regular retainer.

A little more progress.

Should have marked the Wing Placement before I glued anything so this was a bit tricky.

Tacked the forward bulkhead in place for the main body.

I’m working on bevelling the fins/wings, they are a pretty oddball shape so was only able to do about 70% on my belt sander. Now I have to do the rest by hand and have it match the rest.

I’m also facing an issue with the sequence of construction. I can’t put the fins on till I build the outer skin for the rear, but there’s a complication in that I also need to allow for the droid, which I wanteded to build around a keychain camera.

I believe that 3D printing would be ideal for this but I’ve never done any 3D printing let alone design something and it’s outside my budget. Looking for some help in that regard, any input would be much appreciated.

What a creative build :)


Perhaps with 3-d printing if you pick something off thingyverse...and it isn't too big/complicated, I might be able to print it off for you and send down your way.

In last post, the reference to green/grey was in regards to my 3-D print filament that I have.

Thanks for the offer Joe and getting a design already made should be helpful I think.

Taking a look I think the best option might be this one. https://www.thingiverse.com/thing:2722819

However to make it work in the rocket and contain a camera I’ll need to make a bunch of modifications:
1. Only print about the top 1/3 or 1/4 of the body.
2. Figure out the appropriate size relative to the X Wing, but also make sure the camera will fix.
3. Figure out where the camera, board and battery will go.
4. Add mounting points for board.
5. Leave hole for camera and possibly mic.
5. Figure out access for SD card and USB plug.
6. Figure out how to activate the switches and make led visabile.
7. Add some sort of base for mounting to the X Wing.
8. Figure out how to be able to rotate the head so the camera angle can be adjusted.
9. Will also want to be able to take the thing apart, but need to figure out how to conceal any screws.

Which is quite a lot I realise and I’m sure there will be plenty of complications...

If anyone has suggestions about how best to design this, please let us know.

I would think that they charge for the software, but I’ll check anyway.

Yes, there is quite a bit to coordinate to get it to fit together well.

Here is a screenshot of how it looks prior to printing
1 square is 10x10mm

Width is 50mm
Height is 74.3mm

Hopefully this will help you refine things...get closer to what is required.

IDEA: Possibly adjust the 3-d print so it is has a square base...more contact area to glue to rocket. Simpler shape as well.
