Harmonics

Post by Boldpilot » Thu Dec 13, 2007 8:45 pm

Hi Guy's, Is the rumble and vibration of the large aircraft such as the B-36 and the Russian "Bear" which have very powerful engines and large diameter propellors caused by the harmonics produced .Something like the Thump in music from the Bass speakers and which the Hoons love in their cars,aye?
During the "cold war" RAF Phantom's would intercept the large Russian "Bears" over the North sea but have to keep a distance away from them as the crews could not tolerate the Harmonics /Vibration from them.

harmonics..

Harmonics? I guess you could call it that. Actually, it is the cacophonous noise of hundreds of tiny sonic booms from the transonic events of the large cord propeller blades running at full power. I am, of course, too young to have experienced this but the C-130's running up their engines at Hurlburt field can actually vibrate the walls and windows of the shop I work at nearly 4 miles away through the trees and other buildings.

I...would love.... to experience that. I really like those big planes with big engines (it's gotta be a radial) and big propellers. Never before have I been close enough to one....wait....I have never seen a B-39. Down is Mississippi, where my popps lives, there is a large four engine, radial engines, airplane that flies over his neighborhood all the time. One of our family friends is actually one of the mechanic who works on it. I'm not sure what it is....but it's sound as it flew over low, on approach to Keesler AFB, was devestating. It sounded good.
Flying is not dangerous. If you don't trust something that has to be supported by air, stay out of a car unless it has solid tires. And believe me, those kind of tires don't ride good at all.

Hi FSpilot06, Reminds me of the time when I was perched on a pair of steps carrying out adjustments on a 14 cylinder radial engine with a big propellor at full throttle nearly being blown away. This was on the Bristol Hercules as fitted to the Handley Page Hastings, Happy days, BP.

I'd love to be at St. Maarten one day just to be blown off my feet from a departing or arriving 747.

When I was a little kid, living in Colorado. B-36s used to go overhead (I have no idea what altitude but they were waaaaay up there) and literally shake the ground...and I'm not talkin' about a little shake. You could feel the vibrations right down into the marrow of your bones. Something I will never forget and something I have experienced with no other plane.
