A Lockheed "Rounder"

[Milton Shupe]

I skimmed through the Pilot's Handbook looking for degrees of flap and other than a 20%, really didn't find much. I could have missed it though.

Same here, and it seems to talk percent, not degrees.

Also, many of these pages are hard to read, and the pictures that are important, the text is unreadable, like the control stand (ECU et al).

If someone can find a better copy of the handbook, or better illustrations, it will make modeling the cockpit a lot easier.

Thanks

Oh wow! Thanks for that link.

That would be a great option and hopefully much clearer details.

Wow! Another classic in the works!

ok...i know this gets old...but will it be 2004 only? or will it port to FSX?..or a FSX version?

Milton has been making them for for FS9, but giving the source files for FSX conversions. I imagine that this will be the same.

Willy is on it. I do test these on both sides so it should make a reasonable port-over.

With that said, the gmax source will be available for native conversions, as always.

Maybe we can also venture to the PV-2 Fire Tankers also.....

[Volker Böhme]

Here is a research question. What is the width and length of the flap?

Modeling and animating these fowler flaps are things I like to do.
This turned out really nice and the animation looks great.

It is hard to determine sizes of these things but we will do what we can with what we have.

Here are two sequences of the animation at 0 degrees, 15, 25, and 45.

See what you think.

Hi Milton,

according to Badrocke/Gunston's 'Lockheed Aircraft Cutaways', "Wing wake turbulence was cured by extending the wing trailing edge slightly behind the flaps and raising the tailplane above the rear fuselage." There is, however, no cutaway of the L-18, but a picture (p. 23) shows the lower side of a PV-2. The four flap segements run beween guides that extend slightly behind the trailing edge.
The two inner flap segments are overlapped by the wing's trailing edge by around 30% of the flpa's longitudinal length, but this tapers down to zero over the outer two segments. The trailing edge of the flap is a straight line with the trailing edge of the aileron.

The aircraft in question is preserved by the Confederate Air Force.

Best regards,
Volker

Volker,

Thank you for this excerpt.

I believe I have all of this correct. I am attaching some screenshots to show what I have.

Let me know if you see an issue with this.

I also have the tail plane above the fuselage by at least half its depth.

Thanks

I may be going back to Midland soon, so i can get exterior shots but i know that thing will not have an ability to be shot from the inside. I do now a few people who fly PV-2's. Ill talk to them and see if i can take a look around and maybe snap a shot or 2. Hoping that we may have a possibility to see the tanker variant of this because it is a rare tanker. Somewhat unknown.

I agree; great shots there.

Meanwhile, back to the "heavy lifting" on the Harpoon, after many hours sweating the details on the flaps and guides, I have it just about nailed for both sides. Just noticed a slight droop on the outer left side of the left flap. :-/

Tail section is good except for one reversed pivot on the elevator trim right side.

Looking forward to rebuilding the engine cowl flaps and exhaust ring ... ughhhh. LOL
I can't even count all the cowl flaps that must be cut in, shaped and animated. {{{shaking head}}}
It will be a good long days work.

Milton, you are one busy Man - and we like it that way - alot of Folks will be so happy once again ! Mike

Thanks Milton, it's looking great. We appreciate all the hours you put into these projects.
