Ace-Garageguy Posted March 3, 2014 Posted March 3, 2014 Ok, think on this one a bit. Given the rotation of the earth at the equator any object on the equator is traveling at approximately 1,000 mile per hour. OMG !!! OMG !!! Why don't we all go flying off into space??? Like on the roundy-round thing at the playground ???
Pete J. Posted March 3, 2014 Posted March 3, 2014 But it doesn't make a noise like a Harvard because the atmosphere is travelling at the same speed, subject to winds of course. Just as well really!There are many instances in aviation of sonic boom causing unique sounds. The whop, whop, whop of the UH-1 "huey" is the same issue. interestingly it only occurs in forward flight because the retreating blade is subsonic. This retreating blade is also the reason that there is an ultimate speed limit on helo's. Eventually the retreating blade produces far less lift that it can compensate for or it stalls and produces no lift and the aircraft rolls.

Pete J. Posted March 4, 2014 Posted March 4, 2014 What are you talking about??? We are already flying off into space. We are just taking the earth with us!Line from the opening of a 60's movie. "There is no gravity. The earth sucks!"
