Glider Noises
Hi Guys,
My LS-6a makes some serious humming noises. Not wind noises, not loose gap seal tape noise, not noises from the glider not being aligned with the airflow, not noises from my gear doors. The noise is like a loud revirberation or resinance or loud humming coming from the rear of the fuselage. When both of my cockpit vents (canopy and nose vent) are closed I hear the noise. When I go faster the noise just gets much louder all the way to redline. As soon as I open either canopy or nose vent the noise completely goes away. This has not bothered me too much this summer but it's fall now and it's getting cold. My choice to not be cold is to listen to that loud noise or bundle up. When the front nose vent is all the way closed there is still a fair bit of air coming through the vent because of the animal hair as the seal for the vent. I understand that this is done on purpose to keep the canopy from getting fogged up and also to keep the internal/external pressures the same. I am hoping someone has come up with a solution to this problem I am having. If anyone can give me some helpful advice to this problem I would really appreciate it. I am curious if sealing the front nose vent with foam instead of animal hair might help. I'm curious if sealing the rudder with external seals would help. Thanks for any help!! Greg |
