Things equal to the same are equal to each other

I just saw a show on the military channel where they said the Spanish Air Force was producing licensed copies of the 109 through the nineteen-sixties.

I remember discussions on this forum about the airspeed at which the 109 flaps could be deployed.  Apparently the Luftwafffe did not document this since it may have been 'common knowledge' among pilots.  Have any of the guru's tried contacting the Spanish Air Force?  There very well may be a wealth of information on 109 performance and combat techniques.

220mph in my 109 manual, but it was the max speed they could be out. Don't think they could be deployed at that speed.

Would be interesting to know to who they paid for manufacturing 109's? Was there Messerschmitt corporation stioll alive after war or did they pay to germany?

How this licence manufacturing works basicly?

Hi Rotax,

>I remember discussions on this forum about the airspeed at which the 109 flaps could be deployed.  

From a Messerschmitt gaph on the Me 109E:

"Permissable flap deflection depending on speed:"

800 km/h - 10°
480 km/h - 20°
360 km/h - 30°
295 km/h - 40°

(Depending on G load, there's a +/- 5 km/h variation. The speed figures are probably indicated air speed, but the graph doesn't explicitely state so.)

HoHun you sure about those speed? For a 109 E? My first guess is the controlls would lock up before 800km/h is reached. Sounds way to high even for a top diving speed not to mention 10 degree flaps...

I assume the speed limit given is the structural limit, so the flaps will remain undamaged at least up to the given speeds.

Controllability probably is another issue, but as the Me 109 had a trimmable horizontal stabilizer, it should at least be possible to sustain level flight at all speeds in my opinion.

Elevator forces of course were too high to actually manoeuvre at these speeds, but the way I understand that graph, I'd think that the Me 109E would be able to dive beyond its redline speed even with flaps 10° out - in a straight line and virtually out of control, but still :-)
