Fw 190D-13 Hydraulic Ailerons

[funkedup]

I lost track of the thread where this was discussed.  Somebody had a link to a message board and on that message board was the email address of the guy who is foreman for the restoration of the Champlin Fw 190D-13.  I emailed him about the ailerons and he said they are unpowered, just like any other Fw 190.  He says there is no hydraulic system on the aircraft other than the braking system.  If anybody wants a copy of the message or his address please send a private message and I will email you from home.

That D13 has a D9 wing Funked. It still hasnt got the real D13 wing.
 
BTW: I have no idea whether the D13 had hydraulic ailerons, but its a fact that the Champlain 190D13 had a D9 type wing put on it for some reason after its arrival in the USA.

Here is the link were the D13 was discussed in the AH BB

web page

the info about the hydraulic system is out of J. Crandells "Yellow 10".

[funkedup]

Thanks Naudet.

FYI:  The D-13 has the original wing now.  Neither the old D-9 wing nor the current wing had any type of hydraulic actuators.

AFAIK D-9 and D-13 both used the wing of the Fw 190A-8.

funked, here what i found out about the D13 wings.

The D13 wing was unique in its construction amongs the FW series.

1. Ammo ejetion wholes were changed, they had a new shape, and there were only 3 cause the D13 had 3xMG151/20.

2. It had a hydraulic boost system, due to this system the wing can NOT be used on a D9 for flying purpose.


This is why the D13 in the champlin museum had to get its original wings. With the D9 wings attached to it, it could not fly, cause the wings would not take the stress. Now that they are putting the D13 back into flying condition they need the D13 wings.

And J. Crandell has seen the D13 himself, he actually was together with another guy the man who identified it as a D13. He saw the original wing. If he says the bird had a hydraulic boost system, i believe him.

[funkedup]

I guess Allied conspirators must have looted the hydraulics from the aircraft, because they aren't there anymore.  

[Naudet]

Really funked? i will check the book again, tomorrow.


Were u got that info from?

But it still is true that the D13 needs its original wings to get into flying condition right?

[funkedup]

I guess I didn't explain it very well.  I sent an email to the guy who is foreman for restoration of the D-13.  His address can be found in a link that is in the other thread on this subject.  He says they have recieved the original wing from the USAFM and that the only hydraulic system is for the brakes.  I'm going to order Crandall's book and try to figure out why there is this disagreement.

not to seem pro Germany during wwii, but I think they were far ahead of the rest of the world inventive wise as well as technologically.

[funkedup]

Naudet I see you posted in the other forum, good job.

@funkedup:

I found the hydraulic boost system mentioned 3 times in Crandalls book.

1st a little correction:

the aileron boost system was not in the wing, the installation was in the lower fuselage, it could be accessed through a panel in the lower wing section.

Also Crandall mentions, that during the restoration process in germany, the boost system had to be blocked off (i am from GE and i am not totaly sure what "blocked off" means exatly, so maybe this measn it was removed at this time) due to the "non-fitting" D9 wings at this time.

So i still think the D13 had this boost system.

Hope i get an answer soon in the luftwaffenexperten forum.

[funkedup]

Naudet, I think "blocked off" would mean that the ports on the hydraulic power unit were be disconnected from the hydraulic lines.  This would make sense if parts of the system were removed from the plane.  

However, a pump would be required to power any actuation system, and this pump would have to be driven by the engine via a shaft or gear from the engine.  Even if this pump were removed it would still be quite obvious where it had been located.  And Mr. Davis was clear that there is no hydraulic equipment on the aircraft outside of the braking system, which does not require a pump.

I think you should question Mr. Davis about any place on the engine where it looks like a pump or pump drive could have been located.  Also ask him if he has looked in the location where Crandall claims the equipment was located, and if he has seen any "blocked off" equipment or any traces that some equipment has been removed.

I will, but i dont have the email.

Can u sent it to me via private message?

Except for technologies like radar, codebreaking and nuclear physics -- the ones that won the war. The only technology they were really ahead on (by a good margin, not slight margin) was missile technology and it took an additional 15 years for rockets to get big enough and A bombs to get small enough for them to be effective as a weapon system.

Charon, obviously you donīt know very much about the germans.

At the end of the war the germans already had projects for radar guided missles.

Codebraking was done by computers. Guess who build the first computer.
Konrad Zuse, 1941

And do you know who did receive the nobel price for chemistry in ī44?
Otto Hahn. "for his discovery of the fission of heavy nuclei"
(nuclear physics belonged to chemistry in that time)

It was simply luck for the world that nazi-germany didnīt have the recources to build an A-bomb. The knowledge did exist.
