English Electric Canberra

Hello

 

Here is an interesting example of aircraft design in the post-war period.

The knowledge about the area rule and swept wings was partly available.

The most obscure design is this one: The Canbera I think.

The Canberra was designed long before the area rule was devised.  Here it is being used as an example of how things used to be done - though area rule would have been of little use to the  Canberra in its speed range.  The Lightning did not have a wasp waist/coke bottle shape either.

The ventral tank has the same effect so transonic drag was reduced.

Indeed, but this was not on the original design, and the drawing shows a wasp waist.  The Lightning benefited from the high sweep angle giving a shallow rise in cross-sectional area.  The ventral tank is placed in perhaps the only place possible to avoid a steeper rise.

Thanks, interesting paper and summary!

Wonder how much else in science was lost/ delayed due to the war and German ideology...

Here is the point:

 

The area rule was invented 1944 by Aerodynamiker Otto Frenzl at Junkers company!

 

For all who can not read the linked German document.

All this two inventions swept wing and area rule are of German origin and later on reinvented by the Americans.

 

Happy modelling

Certainly did for the larger F6/F2a ventral tank
