As an old seafarer I am familiar with "gyroscopic precession" on gyro compasses but to have to compensate for this when taking off must have been a frightening situation indeed!
It's called gyroscopic precession, for those that care to investigate. I'm surprised they didn't mention that on the show. It's now required knowledge to get a pilot's license, even though modern engines aren't as bad as those old ones.
Funny they do a bit on rotary engines and they get the experiments wrong. All rotaries rotate counter-clockwise, while that gyroscope rotated clockwise. All of the inputs he applied to that gyro would be the exact opposite of what would happen on a real rotary engine airplane.
@mswinman Because most Rotary engine designs from just before the turn of the century up until the end of WWI were only made by a handful of manufacturers (Clerget, Bentley, Gnome, Oberusel) and they all rotated counter-clockwise. There were also dozens of companies that licensed engine designs from these major firms and they all rotated the same way.
There may have been some one off engines made by inventors that spun clockwise, but none that made it into mass production.
@GGigabiteM Ok, thanks for that, for some reason I thought the direction of rotation was as viewed from the cockpit. Isn't the rotation on the gyroscope the same as the aircraft? It looks the same and it certainly does what they say it would do, maybe I'm missing something.
You're not missing anything. When they first show the gyroscope w/o the plane attached to the front they referenced it incorrectly by overshadowing the airplane in the wrong direction with the nose pointing out. When the guy actually attached the airplane with nose pointing in to the gyro the prop of the plane and the gyro are both indeed turning clockwise from that frame of reference which is correct.
@mswinman There was one notable engine that spun both ways, the Siemens Halske SH.III, which used beveled gears on the back of the engine to have the crank case spin counter-clockwise at 900 rpm, and the pistons, connecting rods and crank shaft spin clockwise at 900 rpm.
Many other types were also usually the conventional counter-clockwise, though there were notable exceptions like Mercedes, BMW, Bristol and some Rolls-Royce engines.
that's a little different. with a car, it's an actual torque force because of the drive shaft having to be so long, with the plane it's a gyroscopic force caused by the weight of the engine spinning...
that's great but there is no such thing as centrifugal force.

@GGigabiteM Why do you say all rotary engine rotate counter-clockwise?
