In my first shot of the diving 109 you can clearly see the automatic slats activated. This is/was a clever design. Did any other WW2 fighter have a similar design?

Who is the registered owner of this particular 109 and what is the reg and c/n?

Thanks

Nicolai

The pilot did an excellent job displaying the aircraft. I would imagine it's not the easiest or best designed jet he has ever flown. It looks like he is still getting used to the bird and is making adjustments. On the takeoff roll he waggled the rudder pedals as though it was an old habit from making sure the tailwheel is locked on a taildragger. He pumped the stick a little on takeoff while trying to find a correct nose up attitude and that makes me think the airplane may be very pitch sensitive.
Interesting , it's sink rate on short final. Wouldn't want to get behind the power curve! Also noted was the way the 262 touched down and seemed to veer to the right a little. Almost like when a wheel touches, the wing quits flying quickly, or maybe all that weight way out there on the wing causes it to pitch right. Did he hit the brakes too hard?
Of course it has a weak nose gear but he appears to be holding the nose off for a little more aerodynamic braking. Not much in the way of flaps on the 262. Excellent video and that guy did an exceptional job with the "Stormbird."

Bf 110, Me 210, Me 410, Me 262 all had leading edge slats.

MiG-3, La-5 and La-7 had them.

...Got them back as it was a disaster without. It kind of then became the 410 with a stretch...

The Westland Lysander was unique in history in having flaps operated entirely by the airflow through the automatic l/e inner slats. When speed decayed, the inner slats opened, and they put down the flaps. The pilot has no manual control for either. (It also has automatic outer slats, as per the question.)

Messeschmitt started the automatic slat preference with the high-speed touring aircraft the Bf-108, also in the 1930s.

The Tiger Moth also has automatic slats, normally locked shut nowadays in many cases.

The Supermarine Seagull V, the Australian version of the Supermarine Walrus also had automatic slats fitted.

Great pics and fantastic footage, thanks for posting them up, can't get enough of the 262

Ed Heineman used the German delta technology for the A-4 aircraft. I'm sure the 262 data prompted him to use automatic slats to slow the A-4 down for carrier use.

You are right,an extra 100lbs were added to the nose area to strengthen it,and the area where the main gear attaches to the wong was strengthened to ( it seems that when the design was changed from taildragger to tricycle they didn't make is as strong as it should have been,and would have led to cracks in the attachment area eventually).

There is also a video on Google of the 262 at Berlin,although the camera work isn't to good!(they spend most of the time showing the hosts and a Mig 29) :

Found a section of a the video that James mentioned (i think) that just invloves the Me 262, I blogged it on Warbirds-Online.org but there is a link to it there. (and yes it is a shameless plug to try and get you guys to check out our latest endeavor!)

The Stinson L-1 also had automatic leading edge slats. Made a pretty loud bang when they opened.

Well that just depends....

Gear and Flaps and all hanging out in the wind.

Those are commonly known as Handley Page leading edge slats after the company that developed them. Seems that the Germans took a liking to them more than did the country where they were developed!

Wily Messerschmitt traded with the engineers at Handley Page his invention of the single spar wing for their information on the aerodynamically operated leading edge slats designed by Handley Page. This was first seen on the Bf-108 Taifun . The 108 also has a single spar wing. I believe the Messerchmitt Bf-108 first flew in 1935. The 109 came later and it also has both of the inventions.
As far as the A-4 Skyhawk, they are definitely similar. Both operate independent of the pilot and have to do with airspeed and proximity to a stall. Yes they will deploy in an accelerated stall. Ed Heinemann was such a prolific engineer you have to assume he was very much aware of and educated in everyone's ideas as well as his own.

As the center of pressure on the airfoil moves forward with increasing angle of attack, the slats get sucked out. Not always symmetrically though in practice.
