As the season nears its end for XH558, finally I've managed to get the video of the Vulcan Howl edited, with big thanks to Dave Beech of Northern Accent TV, who helped to edit it.
Unfortunately the footage isn't the best due to the camcorder being an old one, and losing focus when trying to zoom in, but hopefully the best thing is that the howl has been captured both on take off, and also towards the end of the display, as it produced the trademark power climb.
We were in a great position to view the Delta Lady's take off - the Brize Norton control tower balcony!
Enjoy the howl!

Incredible!!
What actually causes the Howl?
Is it to do with the shape of the engine inlets on the leading edge & how the air flows in?
Its because the natural resonance frequency of the air inlet is the same as the vibrations caused by the engines at a certain thrust level. This causes the inlet to vibrate and cause this noise!
Totaly uterly awesummmm nothing else on this planet

If dragons had existed, they would surely howl in the same magnificent way.
I used to fly in B-52Ds and can say that the howling sound was also present in the BUFF on takeoffs using water injection. Water is injected into the intake to increase the local air density and give the engines more takeoff thrust. The best place to hear this effect was at the end of the runway as the aircraft approaches using water injection on takeoff. You hear the howl long before you hear the roar of the jet exhaust.
Would this mean that any jet engine you could put into a Vulcan would make it howl..?
