Name that Plane

[DaveBB]

This was a common design practice. The wing and stab are not a cantilever design, thus the external bracing. Keep in mind that the early Bf 109s had externally braced horizontal stabilizers well into the early 1940s.

Alright, if you have time, post some pictures of these commonly designed aircraft that require 4 external braces to keep the main wing and tail attached to the fuselage.

Look at all those wires on the a/c that held the World speed record (709 km/h) for awhile.

External bracing was a common design practice well into the 1930s for military aircraft, and still used today on light civil aircraft....

A handful of aircraft so horribly designed that they needed the parasitic drag of external bracing just to fly.  Good show ol' Chap.

Until the development of stressed skin structures there was no alternative.  You are faulting the designers for not having invented a new construction method.

[DaveBB]

The agro-plane?  It was designed far after stressed skin.

And is saves weight. As long as the planes are small and the speed is moderate its better to have a light construction w external bracing. Almost all light aircraft have it.

Weight is the issue there.  The drag difference isn't very much at low speeds, but the weight difference is marked.

My lord you're an insufferable one, aren't you? You get proven wrong and you immediately have an insult ready for the evidence shown to you?

Feel free. I know my past, as do most of the boards. I also know my present, and my future. A pathological liar? That's a hell of a jump. What do you ACTUALLY know of me? Anything? I doubt it. Stop being so rude, not just to me, but to all of the individuals here. That response to Widewing was particularly uncalled for.

You've been on the board since 1999? I have been a structural engineer with Lockheed since 1978. How about if I comment on YOUR idiotic post?? Prior to the availability of high strength aluminum alloys (typically 24xx series ), and the evolution of semi-monocoque designs, external bracing was often the only way to handle wing bending moments. And even for some modern low speed applications (say a crop duster), the addition strength and rigidity it offers may still be preferable to the additional airframe weight required to eliminate the bracing.

There are some very knowledgeable guys on this forum, so before you start spewing some half-baked BS, rest assured that some of them (Karnak & Widewing come to mind) will take you to the mat face first.

All of these planes designers made a decision of structural spar weight versus drag I would guess.  Not a bad design at that moment in time.  Material advances and new spar technology including advances in calculation methods would eliminate those today with the exception of the ag plane where is strength trumps drag on this specialty plane(Note the mirror).
