Dutch Roll
Searching older posts for ´Dutch Roll´ provides a lot of information, but I still have one question left :
Where does the name ´Dutch Roll´ come from ?
Does it relate to dutch aircraft (Fokker ?) where dutch rolls were fist observed?

Perhaps it's aviation mythology, and perhaps it's true......
Legend has it that one of the Boeing engineers working on the development of the B47 noticed that the swivelling the the Dutch girls bottoms whilst ice skating was very similar to the new stability problem on the B47.
Maybe it's mythology, but a nice story anyhow.

I was told that Dutch Roll was so named after the rolling stumbling amble of drunken Dutch sailors, of course that could just have been the way Dr Berstein described it to students to help them remember.

Old Smokey is as close as anyone is going to get here.
The oracle speaketh thus:
DUTCH ROLL
The earliest known skating technique, the Roll involves leaning from side to side on alternating feet using the inside edges of the skate. It is a natural movement used in all skating.
The oracle being Google, of course!
The origins of the term Dutch Roll in aviation does indeed come about from an aerodynamicist working at Boeing on the B47.
The phenomena had been identified as early as 1941 as far as I can ascertain through investigation but was mearly lumped into lateral instability problems.

Can I humbly remind you that the DUTCH ROLL was already known in the DC-8, well before the B74 came into production, where a YAW DAMPER was already mounted.
I rember that during one of those many transition flights (zero flight time sims were in the dream of the bean counters) there was a trial of that system, consisting in the full deflection of the rudder, its sudden release, and the subsequent recovery, which took only a couple of cycles; and many more with pilot intervention

Er, Doves,
A bit before the DC-8!!!

The Boeing B47 was the worlds first swept wing bomber, making its first flight on December 17th, 1947

I remember someone mentioning that the term dutch roll is derived from Dutch sailing ships during the times of the East India Company. Apparently, they showed as similar behaviour on water as do aircraft in the air.
Yeh, I know you guys like the Dutch girl´s bottoms version better. Anyhow, just what I heard.
