same thing that happened to the french in WWI WWII.. they had to farm out there problems.
 
Yes a beautiful airplane, NOT!



Or this one,



Now what is ugly about this a/c?

 
The British planes actually flew??

By 1938-40 the French conceded that they could not bludgeon the air into submission any more than King Canute could command the tide and moved to more streamlined aircraft.


The Welly was the inspiration for the B29 so I'm told....

Now this is er, unusual...

Beardmore Inflexible


Even the Germans had a bad hair day with this one Messerschmitt 323 Gigant and this one too...Linke-Hofmann R1

But the French take the biscuit with this..Bleriot 127/2

This thread has drifted on to ugly aircraft as a whole - the 1930's French bombers are difficult to beat in that respect. To quote "Major Howdy Bixby's Album of Forgotten Warbirds" the French are "Lovers, not engineers".

But I'm purely querying tailplanes. The Spitfire is unquestionably the second most perfect aircraft (after the Mosquito) but both have tailplanes which look out of character with the rest of the aircraft. And it's a general theme with British 'planes.
 


Quite right, sorry for drifting off topic.

Unfair on the Tempest! Look at the lighting and the angle of the lighting, that's what makes the tail look a little naff: bad lighting and the wrong angle will show up the pimples on a super-model's face, without the required airbrushing

As for the P-51B to D fin fillet; from what I remember the problem of yaw was exacerbated by the extra fuel tank fitted in the rear fuselage; it was to counter this that the fillet was introduced and metal covered elevators fitted. The pilot's manual recommended emptying the fuselage tank first to restore the c.g.

As has been mentioned, in many cases it was sort of a "trademark" thing. If you could see the tail of a De Havilland, you knew it was a De Haviland even if you couldn't see the rest of the plane.

It was also what the designer knew worked. He might have to adjust the size a bit or push/pull an edge but it worked the last X number of times they used that shape. In the 1920s/30s aerodynamics was really in the dark ages. One book claims Supermarine's first wind tunnel was a hairdryer and a cardboard box. With all calculations being done on slide rules and mechanical adding machines the fewer "new" features on a "new" aircraft the better.
 

The addition of the ventral was all about yaw stability due to the increased torque of the Rolls. The issue existed in the B/C before the fuselage Tank addition. The SOP was to reduce the fuse tank from 85 to 25 gallons before switching to externals.

The only solution was the redesigned P-51H extra fuselage length, reduced fuselage tank capacity to 50 gallons and adding greater area vertical stabilizer.
 

Spot on Tom, There was a danger of the Merlin getting too powerful for the airframes.
I think that the Mustang has a beauty that got better as it got older, the teardrop canopy and sleek profile. A very formidable fighter and one to cherish.

The end of line piston engined fighters had a brutal purpose to them,massive power and presence. The Grumman Bearcat's performance is unbelievable.
