Two shock waves - the main one located on the nose, then an expansion field over the wing and a final shock at the tail where the flow was recompressed. [That is ignoring all the intake shocks!] The two compression shocks are what gives rise to the characteristic Boom-boom on the ground.
Thanks for this, CliveL. Could you please explain 'expansion field over the wing '?
Thanks.
Also, how was the flow re-compressed at the tail? What is the aerodynamic explanation of this?
As the intakes produced shocks, what about other protruberances such a aerials and drain masts etc? Did these also produce (small) shocks?
