Really interesting, the first time, I've heard of tilting airscrew for the Br.941.
Couldn't find any clue for it in Cunys book, but maybe that's only due to
my not very good knowledgeof the french language. Can anybody confirm,
that tilting airscrews were really planned for the Br.941 ? The test rig and
the Br.940 was only for the development of the cross shaft connenction,
I think. But the Br.941 prototype was ordered in 1960, the flight article was
published in 1952, so it may well be an early layout.
