Editor’s Letter
A VERY WARM welcome to
TAH35,
in which we take a
characteristically varied tour of some of the more unusual
nooks and crannies of aviation history. Highlights include
Prof Keith Hayward’s commentary on the political punch-
ups at the heart of government during the start-stop-start
procurement of the Hawker Siddeley (later BAe) 146; and Dr
Andrew Arthy’s minute-by-minute account of the staunch
efforts of Luftwaffe fighter unit
Jagdgeschwader 2
to hold the
defensive line over the beaches of Dieppe on August 19, 1942.
I’m also particularly pleased to present what I am confident
is the most complete history of Argentina’s IAe.30 Ñancú
twin-Merlin-engined fighter published to date, after more
than a decade of extensive archive-digging by South American
aviation historians Ricardo Lezon and Santiago Rivas. This
“homegrown hot-rod” could have been a real contender had
it been developed sooner — but it was largely obsolete before
construction started, thanks to the advent of the jet engine.
If you like a mental challenge, Matt Bearman’s fascinating
article on the aerodynamics of propellers, and specifically the
effects of supersonic shockwaves thereon, will provide plenty
of meat for your brain to chew on. It’s interesting that so little
attention has been paid to propellers over time; as with
aerodynamics generally, historians looking back at the subject
tend to put it into the “too difficult” box. Indeed, realising
that Matt’s article contains some potentially mind-spraining
mathematics and concepts that seem bizarrely counter-
intuitive — pulling the throttle back to go faster, for example
— Managing Editor Mick and I discussed whether it might
be
too
technical. But, as Mick rightly says:
“This article really does advance our understanding, which
is exactly what we should be aiming for; it very satisfyingly
identifies a common thread linking several apparently
unrelated aircraft which, although promising, all turned out
to be disappointing. That is real aviation-history magic.”
I agree — and hope you will too! Enjoy the issue.
