I would like to get as much info on this aircraft as I can. More on the tilting rotors. So please if you have any info on it let us know.
Cheers :pint:

My Grandfather was there when they first rolled the Osprey out! I have always enjoyed the stories he tells me. I'll ask him for some information to give you.

Can you imagine the precessional force on the rotors/props when they rotate the engines? I bet those rotor bearings take a beating!

I hadn't thought of that, but :shock: ! Yeah, it's not just the rotor bearings - the entire engine mounts have to take a real beating...

Waaaaaay back in the "good ole days" when Nieuports and Camels and Fokkers had rotary engines, they would tend to climb when turned to the left and tend to dive when turned to the right. I'm assuming that the prop turned clockwise when viewed from the cockpit, just like american planes do. This is all due to the huge precessional force from that rotating engine.

Not only that they turned significantly tighter (left?) so most breaks were left. Good pilots would anticipate that and lead turn them before taking the first shot that alerted them to his presence

V-22s...What a PIECE! Come on Bell, it's only been, what? 20 years? By the time the first unit reaches IOC, it'll be time to fly it to AMARC. :lol:

Can't blame Bell entirely, as much as I would like to. Between DOD trying to kill it multiple times (Osprey is THE Congressional Pet Rock) and the services adding ridiculous requirements, this thing was bound to take forever.

FWIW, I am on the AFOTEC IOT&E test team as the lead for SIRFC (RF ECM package).

To finish habu2's sentence,
so the local precessional torques are still there to affect bearings, engine mounts and such, but the left rotor and right rotor precessional torques cancel each other. Therefore the airplane does not experience the unwanted effects mentioned in previous posts.
