Aircraft Exhusts...
I was wondering... as there seems to be so many complaints about aircraft noise, why isn't more effort made to make aircraft engines quieter?
Exhaust systems on aircraft seem basic to say the least, I understand that complex systems may add some weight and possibly reduce the power output slightly, is this the reason? ...maybe the rotation of the prop is responsible for the majority of the sound??
If planes were quieter maybe we'd live in harmony with our land loving friends?
I'd be interested in your comments?
