Vertical Stabiliser Design
Have been trying to establish the reasons designers opted for single vertical stabilisers on aircraft such as the Boeing B17, whereas other designs notably Avro Lancaster and B24 Liberator had twin fin arrangements.
It seems to be the case that both configurations provided stability around the horizontal plane needed for accurate bombing results as well as general handling. Would it be the case that a twin fin design was able to absorb more battle damage ie, one fin damaged, the other remaining functional?
I'd look forward to any information on the subject.
