Why was the Ju 52 corrugated?
The corrugated skins on the JU-52 are a strengthening/stiffening measure: Corrugated skins are less prone to bending when loaded along the corrugation (the same reason we use corrugated boxes for shipping).
What happened to the Junkers company?
The Junkers company survived the Second World War and the formation of East Germany, and was reconstituted as Junkers GmbH and eventually merged into the MBB consortium (via joint venture Flugzeug-Union-Süd between Heinkel and Messerschmitt in 1958).
Are there any Ju 52 still flying?
As of November 2018 there are five airworthy Junkers Ju 52 worldwide. Now fitted with original BMW-engines, was on public display at Düsseldorf Airport/Germany before as D-CIAK. This is the Ju 52 restored and flown for many years by the late aviation and science fiction writer Martin Caidin.
Why are ailerons and flaps corrugated?
The diamond (or V) shaped ripples on the control surfaces (aileron, elevator, flaps) are there to increase structural strength.
What does Junker mean?
Junker. / (ˈjʊŋkə) / noun. history any of the aristocratic landowners of Prussia who were devoted to maintaining their identity and extensive social and political privileges. an arrogant, narrow-minded, and tyrannical German army officer or official.
Who called Junkers?
The landowners in Prussia were called as Junkers. Explanation: Junkers was a common word to denote all the landed nobility who owned great estates. These estates were owned by small peasants who had few rights.
Why do ailerons have ridges?
RE: Ridges On The Wing These vortices interact with the rest of the air moving over the wing to speed it up and help reduce the possibility of separation. Many STOL aircraft use vortex generators for that very purpose–especially to force the effectiveness of control surfaces at low airspeeds.
What was the Junkers Ju 52 made out of?
The Ju-52 was built of corrugated metal skin and paid little attention to beauty, features of a typical Junkers design. Parts and pieces stuck out of the airframe, and the corrugated skin, though much stronger than fabric and metal tubes, created stronger air resistance.
Why did the Junkers Ju-52 have corrugated roof?
While there are likely some aerodynamic penalties as a result of this, small corrugations could be within the boundary layer and the overall trade-off between weight (to brace and stiffen the skin internally) versus aerodynamics may be favorable in some designs.
What was the name of the Junkers transport?
Ju-52 History Nicknamed “Tante Ju” (Auntie Ju) and “Iron Annie” by Axis and Allied troops, the Junkers Ju-52 was the most famous German transport of the war. The Ju-52 was built of corrugated metal skin and paid little attention to beauty, features of a typical Junkers design.
Why was the Junkers plane made out of corrugated metal?
It was largely a structural decision. The Ford Tri-Motor which was designed to mimic many things the Junkers plane designs included, including the corrugated metal. …all of which were constructed of aluminum alloy, which was corrugated for added stiffness, although the resulting drag reduced its overall performance.
