Blackadder's Scratchbuilt Thunderhawk


Recommended Posts

Hi there,

 

been following this for a while and great scratchbuilding, wanted to build one myself only had to many projects already so bought the forgeworld one instead.

Can take picture of certain area's if you need them?

I would like to see what the bottom half of the engine looks like. That is where the aux gear case and the CSD, generator and fuel control would be located.

 

Thx,

EB

I've decided to forget about the PVC and make the compressor section out of 0.40 mm sheet styrene I'll do this one to completion and see how it goes. So far every thing is lining up nicely.

The #3 engine basic framework is complete and as usual it has set a standard that I will be hard pressed to equal. Everything came together so perfect than I could believe with less than a quarter mm error between the top and bottom halves and that will be covered by the fairing inboard of the engine so it won't be seen anyway

 

Now all that needs be do is to attempt to reasonably duplicate this on the other side.

Okay, the basic three engines are done now that all needs be done is the final sanding of the mating surfaces where they intersect the wing root and fair them into the wing. An added bonus is that the engines increase the overall wingspan by about 2.5 cm which alleviates my concern that the wings look too short. :)

 

Note that the center engine is longer than the wing engines; this is also true on the 3D drawings to make the exhaust housing come out. Can't be helped and I don't think it will detract from the overall look as the bottom of the hull is rarely seen anyway. I'm not sure how it looks on the FW model but the extra length of this model that gives it that more airworthy appearance necessitates strefching the engine. Makes it hell for engine changes though as two variations of engines must be stocked instead of one.

 

Seriously Blackadder, You're concerned with logistics now; Get a life!

Hope you find them helpful.

Thats fantastic thank you very much. This clears up a lot of problems I have been trying to reconcile with the 3D drawing one being the what I perceive to be the too long exhaust extension beyond the end of the fuselage. I have been mounting the 'drum' completely beyond whereas it is partially faired into the aft hull.

 

Another is the center engine appears to be two engines in tandem which accounts for the extra length but poses the problem of the rear engine burning the exhaust gases of the forward engine! Clearly an impossible situation. Tha will have to be changed on my model to differ from both the 3D and FW designs.

 

And of course the plumbing which appears more viable than the 3D model.

 

Again Thanks,

 

Blackadder

You gentle reader are about to reap the benefit of my stupidity. I went to great lengths to make the core housing of the engine as cylindrical as possible wasting hours in this fabrication. Recent images of the FW engine that have come into my possession have demonstrated to me that this effort while a worthwhile learning experience has been rendered superfluous. It seems there is another curved cowl sitting astride the core housing so I need to make another semi-cylinder of a lesser diameter and affix it to the core cylinder. What is left visible of the core cylinder could have been substituted with a nearly flat piece of stripping a centimeter wide.

Frustrating! HA!

 

Take that smarty pants Blackadder........

 

Thanks a lot Adeptus Custodus! :)

I'm trying another method to affix the cowl to the engine core. This reminds me of my daughter's paper doll cutouts but we'll see how it works. meanwhile I'm going to get that heat gun.

You sir are a real legend.

 

I have nothing constructive to say other then this is truly awesome.

 

And thank you, you have inspired me to start a scratch built Thunderhawk which I will be starting at the end of March. (Although i don't for one second believe mine is going to be as good as yours)

 

Really look forward to seeing more.

Great I am looking forward to seeing your thread.

Well here it's the weekend again and everyone with a life is out enjoying it. Meanwhile I went ahead and detailed up an engine to see what it would look like. There are a few changes from either of the two versions I'm working from and I really wanted to use some of the hex rod I have lying about. so I made it into the fuel injector defuser. It doesn't look too bad and certainly different from the FW tube defuser in the same area. Of course the needs to be a lot more tiny bits to make it look like a real engine but nowheres near as complex as the SR71 engine pictured below................. No that way madness lies.

Outrageously complicated fuel control.

Damn it's hard to believe that engine doesn't turn into a puddle of slag at that temperature!

Engine?! I thought that last pic was some kind of particle beam cannon =O

FYI, the engine pictured in the above post in action on test stand #3. A Pratt & Whitney J58 motivating power for the SR71 Blackbird, that has got to be the most beautiful and fantastic aircraft ever designed let alone built. If we ever get invaded by aliens we need only show this and built with 1960s technology to boot!

 

Don't mess with us we'll kick your a**! :)

BTW that's not photo-shopped, That's the actual test stand photo! I have more.

That's proper HFY material, that. :D

I didn't say it was, I just meant that with some photoshopping it could look like a particle beam cannon. :)

Resting on my laurels for far too long but I have not too much to show. I've been working on the engine detail and before I mount them I'd like to try to give them a bit of fire i.e. high intensity LED's. This is my first effort so be kind I only just slapped this together a few minutes ago.

looking intense. though im a little concerned for the LEDs. I feel like they are a little too bright and might obscure some of the details on the engine? but then again i dnt know if the photo is reacting to the led in a negative manner

Not to worry I'm still playingn with this.

Okay, a while back someone asked me what Chapter colours I was going to paint this beauty (possibly not on this forum)? Well I hadn't considered that far down the line but I did receive some suggestions (Again maybe not from this forum) and I have decided barring a humongous meteorite strike or some other world shattering event I shall be going with this scheme. It just appeals to me adding just the right amount of racial senile decay and a patine of war weary resignation to the inevitable and ultimate end.

 

Whew, that is a depressing scenario if I do say so myself.

 

On a more upbeat note; the engines are just about done and I'll be posting an update soon.
