limjye Posted September 15, 2013 Share Posted September 15, 2013 Hi i have encountered a problem with aileron re-balancing. Apparently, we cant re-balance the cg of the aileron back to the hinge despite adding the maximum amount of ballast permitable at all the balancing stations. What causes this phenomenon? Apparently there isn't any additional weight induce on the aileron due to repair however the cg just seems to shift farther away from the hinge. Also what will happen should the ballast added exceeds the allowable quantity at each individual station. Thanks. Quote Link to comment Share on other sites More sharing options...
Steve1300 Posted September 15, 2013 Share Posted September 15, 2013 It would help if I could see your setup for checking the balance to see if everything is being done correctly. Also, ensure that your scale is in calibration and being place in the correct spot for weighing. If nothing has been done to the aileron and it is out of balance, it either has always been that way or some critter crawled in there and died in an unfortunate location. If you are doing everything correctly and it still will not come back to the limits, then you'd either have to get engineering approval to add more weight or you'd have to replace your aileron.

limjye Posted September 15, 2013 Author Share Posted September 15, 2013 Actually i am just wondering is there any reason why only 2 ballast is permitted at each station? What happens if you put more lets say 3 or 4? And is there any possibility that the aileron might be distorted from the different aerodynamic load in the air hence causing the aileron to be unable to be balanced even when the maximum amount of ballast has been use.

talons1555 Posted September 15, 2013 Share Posted September 15, 2013 This may not be much help, but I balance helicopter blades and water incursion is a problem. Could you have water or foreign material in it? Quote Link to comment Share on other sites More sharing options...
JTECH Posted September 19, 2013 Share Posted September 19, 2013 I am not sure about the why but I do know when you balance a rudder you can use as many as needed, could be because the aileron is so far outboard it would cause more severe balance issues, though that seems far fetched.

steve haigler Posted September 23, 2013 Share Posted September 23, 2013 Just wondering and hope I don't sound stupid, are you doing both? Does it matter? Just thinking if CTM would make a difference from R.toL. Quote Link to comment Share on other sites More sharing options...
miamiair Posted October 1, 2013 Share Posted October 1, 2013 A few things: Do you have it set at the correct angle? Are there any significant repairs to the trailing edge? Have any of the skin panels been replaced? Check the weights, we have had two instances where the weights were "locally machined" where their weight was removed. If you still run into problems, get your LM Tech Rep or call the Hercules Support Center 770-431-6549. Quote Link to comment Share on other sites More sharing options...
tusker Posted October 11, 2013 Share Posted October 11, 2013 .........no faulty hinge bearings.....causing excessive friction!!.........basic setting is OK!!!...IAW Quote Link to comment Share on other sites More sharing options...
