Stunt planes that use Jericho trumpets
Discussion
Are there any stunt plane displays that use jericho trumpets, like those fitted to Ju87 Junkers in WW2? If not why not? Is it just the drag from the trumpet or something else?
It's a pretty (in)famous noise but AFAIK I've never heard it in person from the various air displays (Leuchars etc.) I've been to.

a) don't call them "stunt planes". Aerobatic aircraft sounds so much better
b) as far as I know, no aerobatic aircraft carry silly add-ons like that.
If you do hear a whine, it is probably just the wind in the wires.
(c) No need to be such a dick, ta b) as far as I know, no aerobatic aircraft carry silly add-ons like that.

We get enough grief from the neighbours as it is, without making any extra noise.
The wires on my old Pitts did used to start wailing when having it large though.
Sure, I'd imagine if fitted permanently they'd very quickly become a PITA, just for the occasional display. Can't say I've heard such a whine before or not loud enough to notice, certainly on the Pitts that was on display last weekend at Alford.The wires on my old Pitts did used to start wailing when having it large though.

And whatever location I am on the spectrum, I'm very happy there.
If it annoys others, that's their problem, not mine.
And the one part of the "spectrum" I am definitely NOT on is the "personal attack" end.

Is the high pitched whine not the supercharger?
Sometimes it can be. There are a number of reasons why a piston engined aeroplane can make a whiney noise -a supercharger (if it has one - not all do)
wind in the wires (if it is a biplane or wire braced monoplane)
Air entering or blowing across air inlets or openings in the airframe. The Mustang and the Hispano Buchon (Spanish Me109) both emit a whine which seems to be related to air moving across gunports etc.
At a guess people don't/didn't feel the desire to relive being bombed/harassed by the Germans so the trend never started or even took off.
In the same way people tend to avoid plastering swastikas on anything as a visual symbol of the Nazi's , the jericho trumpets are still recognisable as an audible symbol of them too.
Just a theory.

Doesn't stop airworthy warbirds, models and museum exhibits sporting swastikas (rightly - of course).
I would think the number of people attending airshows in the second decade of the 21st Century who remember being dive bombed by Stukas would be pretty small.
In any case, most Stukas were NOT fitted with the little impeller that drove the siren that generated the noise. If you look at photos of operational Stukas you will normally see a little stub fairing which is the point on the wing where the siren impeller was supposed to be located -

I think swastikas are OK now. Photos of Rolf Harris are the latest social no-no.Now Rolf Harris dressed up as Hitler - that really would bring society down.
