Re: [stratostar] Longmont City Council will take up skydiving noise
In reply to:
For one thing I've never seen a propeller with a muffler installed on it before, in fact last time I checked there has not been one invented yet.... so there is your hot tip of the day.
Well, on the topic of "hot tips", there are prop tip designs that are significantly quieter than the normal prop, and significant advances in prop noise reduction has been made by using composite materials which allow thinner blades and more elaborate blade shapes. Getting FAA approval to retrofit, and finding the $$$, is another matter of course.
