It can look dumb, but I always had this question as a kid, what physical principles would prevent this?
minus-squareTarqon@lemmy.worldlinkfedilinkarrow-up1·11 hours agoDoes that mean the theoretical speed limit for a jet aircraft is how fast sound propagates through the airframe?
minus-squareDrewlinkfedilinkarrow-up1·11 hours agoNo, a jet aircraft moves by pushing air behind it, the theoretical limit would have to be somehow related to that
minus-squaregrue@lemmy.worldlinkfedilinkEnglisharrow-up2·5 hours agoThe theoretical limit could be related to either of those things; it just depends which is lower. (It’s almost certainly the one you mentioned.)
