Hidden food for Fokker triplane experts

Taz:
After reviewing the data on the V.7, I am recinding w.n.1884. The disposition
of the V.7 are.
V.7(1) w.n. 1788 ShIII, re-engined, became Fok.DR.I 120/17.
V.7(2) w.n. 1830 URIII, re-engined, became Fok.DR.I 100/17.
V.7(3) w.n. 1919 GeoIII, re-engined,became Fok.DR.I 599/17.
V.7(4) w.n. 1981 became 90.03, UR.III engine. Went to Austria.
The first three V.7 aircraft are accounted for, V.7 1981 is the only one that did not become converted to a DR.I. V.7 w.n.1981 must have come back from Austria and it is what we see in the back right in the Fokker Factory shot.
Blue skies,

Hi all,

I'm leaving this thread to the Dr.I experts.

Here are some images already posted, but I'll put them together.
Something of possible interest, the following Factory photos were taken very close together in numerical sequence, but not necessarily very close in time, but could be.

Sorry for the big size, but you'll see the reward.

Factory photo number 1050. Note that we can see on the sign hanging underneath;

V.7 160
Siemens (?)
K 8018

Here is the entry from the 1917 experimental aircraft list.

We see the Kommission number, 8018. This locks in the aircraft to being werk number 1788.

factory photo number 1052.
Of interest is the bottom wing is not covered, but it appears the aircraft has "time" on it.
Also if you look immediately behind the cross wires of the landing gear, and go down, you will see another rotary motor on a wooden hexagonal motor stand.
You can just make out the valve rockers.
Could be another motor for the aircraft.
Also you can nearly make out the numbers on the valve rockers on the installed motor.

factory photo number 1055.

The above image has been cropped from the photo of the V.11 undergoing construction.
It appears they are changing out motors.
Note the multi-hole cowling on the floor to the right.

more to come...

Best,

These are closeups of materials I've already posted on other threads. Taz was asking for larger blowups of the sheets, so here they are as they pertain to the Dr.I and V.7's.

To fit the format of the posting confines, I'll just post one thing here and follow up with more on the next posting that needs to be together.

The following image is a blowup from the Fokker wall chart of New Aircraft. Of interest is the far right notation of "V5S 110PS Siemens".

Here are excerpts from the Typen lists pertaining to V.7's. One is from the Factory wall sheet the other from the formal listing.

and a blowup of the motor listings from the above entry so as to clarify.

Next, the heading from the more formal Fokker Typen chart.

Sorry this turned out so damned big!

It's clear on the later sheet.

More to come...

Sorry mistake.

Dave_Watts · 19 May 2006, 11:33 PM

Here are pertinent entries from the experimental listings for V.5's, Dr.I's, and V.7's from the Fokker factory for 1917 along with the summary listing made in 1919.

More to come....

This is August 23rd. Note on the following it is typed; "V VIIm". Evidently for Gnome?

Last bit...

Hope this is of help. I may go in and crank the size of these entries down if it bugs you guys. I wanted to make certain you could clearly read the entries.

Best,

Hi Dave,

The last photo is an interesting one, is that a 160 hp Goe in the V.7 behind the SH III on its back in the foreground? The engine cowling lying next to the V.7 looks different to the other V.7 photo above which has a V shape to its underside, this one curves upwards when viewed from side on.

Langdon, et al,

The "spider" mount in the background differs significantly from that of the Sh.III fitted V.7 that is shown san's cowling in the previous outside shot w/ the massive wooden propeller. The other earlier photo shown of the Sh.III tilted on it's nose is a good closeup of the Sh.III version mounting structure.

I was going to ask about the engine in the airframe behind in that different style mounting. It appears to be a twin-row engine w/ 7-cylinders per row. Is this the Goebel Goe. III? Or is it a 160 Oberursel U.III? (Since I don't know what a Goe.III looks like, I would almost say it was a U.III) I didn't know there were two twin-row engines. Everything I've seen up to now fitted with a Goebel Goe.III engine has a cowling that virtually hides any detail of the engine. (Roland D.XVI monoplane is all I've seen thus far) What does a Goebel Goe.III look like? Was it a twin row... two 7-cylinder Goe. IIs bolted together?

The deep cowling on the floor would definitely be for the twin-row engine.
