Tilt rotor dynamics
Tilt rotor dynamics
(OP)
Other than the way the V-22 does it using a screw/ball jack (hydraulically controlled) does anybody know of a different way to tilt the nacelles of a tiltrotor a/c????
Also: Anyone up on drive shafts? I need to design a way of driving the tiltrotors proprotors on one engine? Is axis gearboxes and interconnect shafting the only way???
Any help you can give me would be gratefully received - Am getting frustrated at the lack of information out there!
Thanks again

You could talk to GKN Spicer, or Dana (suppliers to auto industry) for existing products.
Regarding nacelles, not sure. I quite like the idea of using either cyclic pitch or a trimmed stator/wing, so that the airflow itself controls the nacelle angle. Would need some work on dynamics.

Im fairly sure that the V22 uses a hydraulic cross drive, and not a direct shaft. Off memory its pressurised to about 5000psi. One of the concerns of V22 critics is that to save weight, the hyd lines are very thin walled titanium, and at the pressures being run, one shot could bring down the aircraft.
What dont you like about the srew jack system? seems to work OK. I think it can rotate upto around 5deg/sec.
What size aircraft are you working on?
How are you Mart?

I'm now an expert in fluid dynamics and the Navier-Stokes equation (apparently)
How's your project? Sorry I went offline a while, just never got around to reconnecting. In the end, I decided that I would be too distracted from revision - believe me there was enough of that! I'm fully broadband compliant now, and ready for non-commerce

When you get a chance drop me your new email to my adress. Your not allowed to post email adresses on the forum, got a kick from the mod for that.
Drop me a line, so we dont send this to far OT.
