The trailing edge flaps on the tailplanes were for additional pitch authority at low speed. They could only be operated when the wing flaps were down. When the wing flaps were retracted, the tailplane flaps were locked in neutral position.

 

 

Interesting. I always thought they were used for roll trim. I think its the only aeroplane of its kind to have this design feature, but given the great length of the fuselage i can see why additional pitch authority would be needed at the low end of the speed range, given its soft-field operating requirement.

Great work!
I have only one remark - the flaps of TSR.2 are consist of two sections.
Without the longitudinal plate joining them.
Plate is a museum revision!

 

Thanks! I'm not so sure about that being a museum revision, though, as photos of the underside of XR219 in flight seem to show the plate that joins the two flap sections. It's fairly easy to see as the plate is white and much of the bottom of the flaps on XR219 were titanium. In Burke's book, each flap is described as being manufactured in two sub-assemblies, and then joined. Photos of XR219 during the flight test programme also don't seem to show any differential movement between the two flap sections on either wing, so it would appear that the flap acted as a single unit. As always, though, I could be wrong!   :)

 

Cheers,

Bill

Each of the control surfaces was trimmable but moved in its entirety to perform that function.  The “elevators” gave increased pitch authority with the flaps down as described by Bill.  TSR 2 was one of the first, if not the first, to have tailerons providing both pitch and roll control, a feature adopted later on Jaguar and Tornado, for example.

It might be very similar to the gap filling plates ("rain gutters") between the elevon sections on a B-58, a plane that Igor knows quite well.

In Burke's book, he states that the two wing flap sections were joined by a "spigot," which in my neck of the woods means a faucet. Perhaps it means something more appropriate in the mother tongue?

So, I've done it again. I've run out of parts. I think I've actually used them all, as opposed to Memsahib hoovering them up. I had to resort to the bomb bay doors that came with the kit as I did a superb job (if I do say so myself) of breaking the resin ones. So here is how she stands today:

Try as I did, I was unsuccessful in replicating a bit of bloody scalp on the antenna.   :(

 

I have some errands to do today and then I'll have a go at shooting some more pictures and making a proper RFI. I'm a bachelor this weekend, since wifey is off at the casino again. I hope my portfolio can take the hit.

 

There has to be something that I forgot to do, but I'm drawing a blank. I thought about adding the intake and exhaust covers, since they are part of the CMK set and are rather nice little castings. The red on the intake covers were help add some contrast to the sea of white. (If I think this is a sea of white, wait until I build that Valiant.) Let me think some more about that. Ta for now!

 

Cheers,

Bill

:goodjob:  fantastic  - and as far as i am concerned truly inspirational!

PS spigot = a short cylindrical projection on one component designed to fit into a hole on another.

Outstanding workmanship as always with your builds.

Photographed in the right setting could well be taken for the 1:1 version.

Did you say Valiant next?

Beautiful; looks like a real aircraft, which is hard to achieve with any model, let alone an all-white one.  Brilliant.

I'll keep the word 'sublime' for the RFI. 'Wonderful' will do for here. Love everything about it, but one particular thing that floats my boat is the canopies with their white and natural metal portions, open at just the right angles.

If that had a little foot level fence round it it could really be XR220

 

I have to admit Bill, when I damaged myself on her I wiped her clean of errant DNA so what we have here really does represent my favourite TSR2

 

Clean and lovely

 

And yet again proves you the Whitemeister

Simply beautiful, Bill.

 

I'm not sure if its an optical illusion caused by the camera angle, or if its because that big panel on the side is open but the forward fuselage seems to have a foreshortened "chunkiness" to it..... which it didn't seem to have in previous photos.

She really does look like she’s waiting for the lineys and crew to walk out and get her ready to go flying, having not long been towed out from the hangar after a little bit of rectification work.  Looking forward to the RFI shots.

All I can say is it looks perfect to me. I really cant think of any other superlatives to describe this one. This whole thread has been amazing and very very inspirational. Looking forward to the RFI.

 

Thanks for sharing Bill.
