Prop sync and noise in twins
Same here Dudley..
I have a "few " hours in a 310... I just set them manually, they stayed in sync very well I have 2500 hrs on the boat, no auto sync, although they make them. You engage it once the vessel is moving fwd in gear, then use one throttle (usually the Starboard) and the Port engine tracks the master.. The 1st sign of engine trouble is the engines going out of sync without any aparent reason... Cheers! Dave On Mon, 21 May 2007 22:46:39 -0400, "Dudley Henriques" wrote: "Dave" wrote in message .. . Yes... it can be REALLY irritating.. I have a twin engine boat, same issue... VERY annoying.. to me, and many others.. Some don't seem to mind.. (?) Not only the noise, but the vibrations , when out of sync, can be very annoying as well... Dave We had a Cessna 337 on our line for charter use at one time. It had a sync gauge. Strangely enough, whenever I had occasion to fly this bird I always ended up syncing the props by ear. You could easily feel if one of them was out even by a small amount of RPM. Dudley Henriques |

Strangely enough, whenever I had occasion to fly this bird I always ended up syncing the props by ear. You could easily feel if one of them was out even by a small amount of RPM. Logically the smallest differences would also be the most annoying, since they would result in such slow variations. And in theory you should be able to eliminate them by adjusting RPM manually. But since the Baron has a prop sync switch it occurred to me that perhaps the RPM levers aren't precise enough to make it easy to sync the props (?). I'm still not clear on whether or not this switch actually moves the prop levers or what. If it does, it sounds expensive, since it needs an actuator or servo in the cockpit or along the linkage. If it doesn't, it means that some of the engine control positions might not accurately reflect the actual engine settings and that engine settings might not obey the control movements if prop sync is operating. -- Transpose mxsmanic and gmail to reach me by e-mail. In the baron I got my multi in, you had to first get the props sync'd up to within 50 rpm. Then you press the sync button and it fine tunes the prop governors to get them exact. At least thats how I remember it, it's been a while. Get a POH, it'll have detailed descriptions of the system. IIRC Beechcraft POH's are pretty expensive (over $100) Wow, the modern CFI, waht a mrvel he is. Bertie Well I'll bet he can spell-check, fjucktard. When I get senile dementia, I want to be just like Bertie Butnip! |

Mxsmanic wrote : I note that the Baron (and presumably other twins) has a prop sync switch that somehow synchronizes the prop speeds on both engines. From recordings I've heard of the interior noise of the aircraft, it does sound as though props that are just slightly out of sync can produce a very irritating intermittent noise as they move in and out of phase. If you want to simulate that accurately, just talk while your's jerking off with your sim Berti e Perhaps you could drill a hole in your "English As A Third Language" textbook and hump the snot out of it. Leave it open so you might learn something in that 5 second interval betwixt engage-disengage-ment as you peer out the airport hotel window for a little (OH!) plane spotting. |
