RE: A bit of Technical Education.

I´m all ears (eyes)!

Christer

Sometimes I wonder why I bother?

Well, I don´t know what You did to upset P9306 but, a simple thanks would have avoided upsetting me!

RE: hello from berlin

[updated:LAST EDITED ON 11-03-02 AT 08:33 PM (GMT)]It´s located in Gatow, a suburb west of Berlin.
You don´t reach the museum from the front entrance.
You have to go around to the back.
There´s a gate in the perimeter fence and you go across the runway to get to the hangers.

I believe there´s a map on http://www.luftwaffenmuseum.de

Hope this helps,
Christer

Came to think of a good resource:

http://www.shellgeostar.com/share/

Enter Berlin as the starting point and Gatow as the end point.
When prompted choose Gatow with postal code 140.
Click full page map (or whatever it says) and You see that it´s not difficult to find.

You can also get a city map over Gatow and search for Gross Glienicker Weg. It´s a long one and when You consider turning back, don´t, it´s just around the corner when You get to a few summer houses (I guess that´s what it is).

RE: Why on earth……….?

I think that the BBMF (RAF) have leaned quite heavily on Rolls Royce to get that assistance. Today RR have no responsibility for any of the piston engines, at least not to my knowledge, since the designs are more than 20(?) years old.
A modification to the Griffon 58 would set them back to square one regarding application of liability laws. If something should happen, then the lawyers would come down on RR like a ton of bricks.
The question mark after 20 means that I don´t remember the exact legislation, Clinton did limit it from “for ever” to a specified number of years though.

So, if you want to fit the Griffon 58 you´ll have to accept the contraprops.

Thats just my 10 euro cents worth,

RE: Request for Uncle Keithmac!

Hi KeithMac,
I´d like to start with a thanks for Your answer to my Centaurus question. I didn´t think that the situation is that serious.

I´ll also have a go on Your contraprop question and this is what I´ve learned about the Seafire 47:
Seen from the pilots seat the front propeller rotates counter clockwise and is the master to which pitch is applied from the pitch control unit and the pilots lever in the cockpit. Pitch is transferred to the rear propeller via a translation bearing. If this bearing fails the rear propeller goes into coarse pitch and will provide nothing but drag. The front propeller will have to do all the pulling against the will of the rear one and full power has to be used to maintain flying speed.

Is the rear propeller different to the front one in other respects? Maybe they differ in pitch range since the front one rotates the airflow against the rear one? Maybe the airfoils differ due to different angles of attack? I don´t really believe in the last one but maybe the first!?
As You probably have understood by now, when it comes to me the questions always outnumber the answers.

Regards,
Christer

RE: For war movie fans…

Sadsack,
don´t go by the counter, it´s not reliable.
I´ve gone in and out on a few occasions to test and it never registers my visits!

BooHoo, I don´t excist 🙁
