    @ Chris

    thanks very much. A somehow sinister website but it shows exactly what I wanted to see. My google search did not point me on that .

    @ Richard,

    thanks very much, too. Excellent series. I think I should have volume 1 but did not find it 🙁

    It’s not a Klemm 35 at all ,but it’s a Klemm .
    A new design ,something like Beetle and new-Beetle ,Mini and BMW-Mini ,Fiat500 and new Fiat500 🙂

    This comparison out of the automobile industry confused me a bit as I layed stress on ‘retro’ -design which is the idea behind that cars. I began searching for contemporary replicas.

    I should read my printed sources more thoroughly even when there are no pictures, but finally I found the following in [1]:

    In fact the Klemm KL 106 was a completely new design but resembled the Klemm KL 35D. The Kl 106 was one of four sport- and touring planes which were built in the years 1938 and 1939. The others were the KL 105, Kl 107 , and Kl 151. In all four designs there was applied the newly developed wooden semi shell construction.

    The Klemm KL 106 was developed for an American license holder . Ten prototypes with the Hirth HM-505 engine were built. Shipment of tooling ,devices and prototypes was already prepared when WW 2 was started by Germany and the business relationship was cancelled.

    @ Richard,
    where is your picture from ?

    Obvioulsly as seen in your mystery picture above the Kl 106 has more pointed outer wings which puzzled me in my original considerations. The only picture I found in the web is in a Klemm biography . Here , too, I have the impression that the Kl 106 has more pointed wings .

    After first considering it to be too simple it was just a Klemm 35 I came back to it. Yes a Klemm 35 of yet unknown subtype as the photo does not have the best quality.

    I think the elevator trim tabs are very characteristic and it has a gull wing.

    “Ducted propeller” and “shrouded propeller” did not work, either, this morning. Browsing Putnam´s Douglas and Boeing books did not help. too.:confused:

    It seems not to be a Pietenpol.

    Moze,

    You can rule out Europe

    Does that rule out Great Britain and Russia , too ? Or do you count them as Europe , like me ?

    DC-3 Barrel Roll Confirmed by Photographer

    N49AG c/n 11737 was reported to have barrel rolled at the La Comina Airshow Italy on 26 June 2010.

    There is a picture of it upside down in the latest Propliner magazine.

    DC-3 N49AG is pictured upside down in Propliner magazine No .123 on page 5. Via the editor I got into contact with the photographer Ugo Vicenzi.
    He confirmed that the DC-3 did a barrel roll. After asking back again I got the permission to reproduce his additional comments here.

    The picture that he submitted to Propliner was not manipulated, only cropped, as the stunt was performed very far away from the public and even his 600mm lens wasn’t able to capture a full frame DC-3 shot.

    A video on some video sharing site would cut short many discussions, but on Saturday, when his picture was taken, there was only little crowd as evidenced by most of the pictures that appear on forums and websites, almost all taken on Sunday, when the DC-3 exhibition was more sedate with just some vertical wing bankings.

    The picture clearly says that light comes from above the plane. DC-3 display was mid afternoon, so one may judge oneself the relative angulation of sun and the wings.

    Regarding capability of DC-3 to perform a roll, he can remind a story that he heard at Officine Aeronavali, which has been a customer of his company for decades and where he spent months working. Old engineers remind that at the end of the forties, when Aeronavali was overhauling a large number of C-47, test pilot Stoppani (who before joining Aeronavali was the famed chief test pilot of Breda and CANT) used to roll the C-47s before delivering to customers. Once he attempted a tonneau [Italian for roll], but midway he felt that the stress to the airframe was excessive and concluded the manoeuvre with a barrel roll.

    Should read BG-12 BD as to my sources.

    But anyway N3362G seen on the unretouched picture below is rather a BG-12 B according to this source
    http://aviation-safety.net/wikibase/wiki.php?id=5424

    Dou you have pictures of the “BD” ? I´m highly interested.

    Nontheless: You have won !

    EDIT: Have just looked up in Janes´s All the World Aircraft1968-69: The BD “..differs from the B model only in the wing, which is now built with no change in incidence between the root and the tip.” Picture only for the BG 12B present in Jane´s.

    Here is pictured a BD in the National Soaring Museum USA

    From the Jeppesen Instrument/Commercial Pilot Manual:

    “The four fundamental flight maneuvers–straight-and-level flight, turns, climbs, and descents–are controlled bychanging the balance between the four aerodynamic forces: lift, thrust, drag, and weight. As you know, opposing aerodynamic forces are balanced in straight-and-level flight. Lift balanances weight, and thrust balances drag. The airplane is in a state of dynamic equilibrium, and there is no acceleration in any direction. A change in any one of the forces will result in an acceleration until equilibrium is reestablished.

    That is nothing but formulas expressed in words.

    But against technical formuals there is room for interpretation and preconceived opinion.

    But why not throw away even this text ? I cannot imagine pilots think of dynamic equilibrium or that change in any one of the forces will result in an acceleration etc. I fear such terms are often used to show knowledge by people not knowing the exact meaning of them or just to make an exam appear difficult.

    I cannot get a licence because of bad eyesight. But the 50 hours or so I flew with instructors , just to get the feeling “how flying works” I never thought about such terms and did not hear them from instructors either and was still able to do circuits and airwork.

    Balance of Forces

    You have weight acting downwards to earth regardless of position of a/c in space.

    You can oppose this force by assuming a force opposing it with the same value exactly opposite.

    Assume this force acting upwards vertical from the earth is “lift” which is generated by the wing moving in the air.

    Balance of forces is satisfied.

    But besides weight and lift you have drag in the line of the flight path. So what opposes drag to satisfy the balance of forces then ?

    ….that depends how you define “lift”.

    Lift= upward force vertical to the earth (green dashed vector ) : YES.

    Lift= Force created by the stream around the airfoil,
    perpendicular to the wing resp. flight path (red vector ) : NO

    BTW the Jeppesen Manual speaks of principles , which apply in climbs and descents and that could easily be interpreted as related to forces are balanced in straight-and-level flight and do not state that lift and weight equal in the descent

    Could you please reduce the size of the retouched aera a bit so that one could see the exact outline of the fin, and perhaps the shape of the rudder ?
