Schön Dir wieder bei der Arbeit zusehen zu dürfen Eric.

RE: Partially Recessed racks
I based my design from the 3-views I took from the Luft46.com site. And that one does not have a semi-recessed bomb rack.
I see some pros and cons here....
PROS:
- Non-recessed : The fuselage would be easier to design and build.
- Semi-recessed : No need to make a bomb rack since it will be "hidden" when the bomb is attached.

CONS:
- Non-recessed : I'll need to make a bomb rack.
- Semi-recessed : I'll need to punch a concave surface. That's another wheel well, which makes assembly hard.

Anyway, I'll make a few experiments as well to see how it will turn out.
Thanks again!

Hello Eric my friend.

I'm very glad the bombrack info helped.

Part of the reason the original Hs.132 design was re-worked to incorporate a shallow recess for the SC500 bomb was because of the extremely marginal ground clearance beneath the bomb if it was external to the fuselage, and carried on either an ETC 501 or ETC503 rack.

It was the necessity of reworking the design of the Hs.132 that delayed its' completion and flight testing as prototype and thus allowed the Russians to capture the incomplete prototype.

Basically, the design team had two options: rework the design to include a shallow recess for the bomb, or rework the design to incorporate longer landing gear oleo legs. Which would have meant redesign the landing gear bays, and the wings, etc. Not surprisingly, the shallow recess was the much preferred option. But few actual non-production drawings as captured reflected that decision, which had been taken late during the building phase of the initial prototype.
William Green "Warplanes of the Third Reich" refers.

Taken all in all, I'd be inclined to "cheat my way out of the dilemma" by simply including the bombrack claws protruding from the fuselage tube.
Which is the compromise suggestion I'm very respectfully offering to you.

That way, most problems as you outline in your "Pros and Cons" are minimised.

Kind and Respectful Regards Eric my friend, Uyraell.

Or just have an outline to cut a hole to set the bomb into, which then could be detailed if the modeler wished to leave the bomb off...

Sorry for the lack of updates/progress.
Work has been hellishly hectic over at the office.
And of course, it doesn't help that the summer heat back here is crazy hot and humid. Just yesterday, the mercury peaked at 34C with a RealFeel(r) of 42C. I don't know how they calculate that RealFeel(r) temperature, but I sure am inclined to agree with it fully!

Now back to the topic at hand.


First the landing gears.

Then the bomb rack. You guys were right! I did the landing gears and tried to imagine the plane tilting up as if it was taking off. Had the bomb been affixed on an external rack, the fins of the SC500 would have scraped the runway. So remi-recessed would have been the way to go.

Now the next step would be to freeze the patches to produce the wireframes. Then simplify + boolean galore to get the wheelwells.

I'm glad the info helped Eric my friend.
Enjoy the summer weather, because I can tell you "summer" here wasn't all that summery.

Meanwhile, I'm enjoying seeing your Hs.132 evolve.

Kind and Respectful Regards Eric my friend, Uyraell.

Eric,

The HS-132 is really coming together nicely. I'm glad to see you back working on it. It looks great. I look forward to your next installment.

I understand your plight. I too have had my work load increase a great deal with a new job and project as well as Spring thinking it is Summer at times.

I've been continuing work on this model in short bursts. As such, I really didn't consider each burst as "progress". I decided to wait until I had something significant before posting here again.

So here it goes.

I first started with freezing the patches to produce the wire frames, like so:



Kinda messy. I wouldn't even dare send that data to Pepakura.


I then whipped out the KNIFE and started working on the fuselage by erasing some edges to simplify the shape.


Then I started working on the wings:

Using the knife tool again, I got rid of excess edges. My goal was to produce a wing that required only 1 piece. In other words, I'd like to try to get rid of the two extra pieces that I usually use for making wing tips on my other models.


After simplifying, I did a BOOLEAN (Wing minus Fuselage).

Now for the Rudder:


Unlike the HS162, which had a flat leading edge, this one has a round leading edge. I started by getting rid of all the vertices in the red shaded region to flatten out the surface of the rudder.



I meditated long and hard to think of a way to minimize the need of having a seam/joint on the leading edge...but I gave up. Sorry. I'll have to live with a nasty seam/joint on the leading edge.


But as a consolation, I've thought of a way to keep the leading edge as "round" as possible.


For the elevators, I did pretty much the same operations as the wing.
Afterwards, I did another boolean operation: Elevator minus (Fuselage plus Rudder).


Now on to the engines:


Again, just a couple of edge erase operations using the knife tool.


The engine mount/faring was done first by doing a boolean: Faring minus (Fuselage plus Engine). I then cleaned up the result by deleting unneeded edges and vertices.


Moving on to the bomb:




Knife tool to the rescue! Plus another boolean: Fins minus Bomb.


And to conclude my progress report, here's a shot of the model so far:



SLEEEK!!!! I can't wait to convert this into cardboard!

I still need to scoop out the wheel wells and covers for the landing gears though.

I'm really enjoying seeing this design evolve, Eric my friend.
Your explanation is a good set of tips and hints, which are, I assure you, warmly welcomed.

Thank you for keeping us updated, and may your success with this continue.

Kind and Respectful Regards Eric my friend, Uyraell.

[eric_son]

Thanks, Uyraell!
I'm happy to say that I've made some small strides toward the finish line.

As with my previous post, this post is just a summary of a couple of small steps I took when I had the chance to steal some time.

My next activity was to do the parts that I liked the least -- the wheel wells, and covers.

Then made some last minute adjustment such as adding gun ports.

And finally, I unfolded the model in Pepakura. I'll be using the flattened model for UV Mapping later on.

Next up...UV Mapping, then Skinning, then Fillers/Formers...and hopefully...the BUILD!

[Uyraell]

You describe recent progress as "small steps", yet in those steps achieve miracles I could not as yet so much as think of attempting.

Truly, Eric my friend, it is a delight seeing this design evolve step by step, having each explained to the reader and thus teaching how it is achieved in the design.
I am very grateful to you for this knowledge and the care with which it is taught.

This thread is one of those that I very greatly enjoy, for all of the reasons above, and that it will result in a model of an aircraft I have long sought.

Kind and Respectful Regards Eric my friend, Uyraell.
