Vibration Questions?
Vibration Questions?
Hello All, new guy here. I realize that I am really late to the party as the last post was in November/2011. However, if vibration in a gyro is as serious as it is in other aerodynamic systems, I think this is a critical topic worthy of ongoing discussion (at least to a person new to gyros). Considering that point, I have several questions regarding the vibration issue, to wit:
1) Are there any data on how much, if any, sympathetic vibration from the control linkages/components add to the overall vibration and/or subsequent resonance of the rotor assembly?
2) Has there been any resonant coupling noted between the rotor and the propeller/engine?
3) Has anyone measured vibration levels with the hard linkages removed and replaced with either "fly-by-wire" or cable (Teleflex?) systems?
4) Does anyone have any experience with using Sorbothane gaskets, grommets, pads or other such vibration sinks in gyros?
I brought about half a square meter of Sorbothane with me to Australia from the USA. I had been experimenting with it to for ultra-lightweight, virtually solid-state, shock absorbers for landing gear. As such it may have a tad too low a durometer but it would still be worthwhile for testing (the lower the durometer the softer it is and the more rapidly it would wear out). If anyone here in Australia is interested in working with it, I may be able to part with a chunk of it (it is really expensive so it wouldn't be a huge piece...don't mean to be such a cheapskate :sorry: )
If you are in the USA or Europe, it would probably be easier and cheaper just to buy it there or request a sample.
Jukka, is there any chance you will be writing-up the results of your additional testing? If so, I would be very interested in reading it.
Anyway, thanks everyone for your time.
Regards,
KD
