Hi,
here I drew profile of the Tu-2 bomber:



It is based on the photos from Massimo's Mig3 pages:

and


The first round of the corrections (upper profile of the nose and upper profile of canopy) is already behind. However, it is really challenge to find reliable drawing and detailed photo, especially from the war-time era.

Hi Misos,
please check the rudder and stabilizers, they were of two different height according to  the version.
The shape of the glazing and struts doesn't seem convincing too.
The rear upper part of the nacelle looks angular on the photo.
The intake over the engine cowlings looks smaller on photos.
Regards
Massimo

Hi Massimo,
do you have, please, reliable drawing that shows differeces between "early" and "late" type of vertical stabilizer&rudder?
Landing wheel struts/legs, same as windshield, are made according to the photos from late Tu-2 walkaround at Monino http://sovietwarplanes.com/board/index.php?topic=1677.0



"The rear upper part of the nacelle looks angular on the photo."

Thank you in advance.

Excellent job on tackling the Tu-2 and it's elusive cammo schemes!
I hope You will extend the range of profiles to late-war machines  Smiley

This is not entirely true. Early and late editions of the Tu-2 have the same height of the keel. A "high" keel was only on the Tu-2D (of 4 aircraft)
The project Tu2D were taken from the number of airplanes 7-Series aircraft "713", "714", "716" and "718" sent to Moscow, where he underwent a modification at the factory number 156 in long-range bombers.

Hi Misos,
about the stabilizer, it looks that the low tail was characteristic of the prototypes. seems that the plane you're drawn is 100716 at nii vvs in 1943, it was born with low tail and then extended upwards; th modification is vaguely visible on the photo with a lighter crescent moon  part on its front and top.
I've sent some scans from Airwar, it should be a copy of Polish Loctnicze. I can't assure that they are perfect, but show some high and low tails.
I see that the corner of the nacelle is a bit rounded. Probably the idea of angular is due to painting.
The Chinese plane looks to lack of a nearly horizontal strut on the side, visible on the other photo. The look of the part should be a rounded frame around the rear glass, plus two nearly horizontal struts connecting it to the vertical one.

Massimo
Low keel was only "103У" and "103B"
Tu 2 throughout the war had a standard keel unchanged Besides 4 Tу 2Д
And if you are talking about the difference in the keel (photo below), then it is a sample of the post-war 1946

Hi Johann and Misos,
according to Aviakollectsia, 1(2) 2008, Tu-2 part 1, this plane was seen with its tail in two different configurations.

Hmm ... I would not have believed this book. The documents concerning the order and the whole set of production equipment and devices,
It works according to the list compiled by Ch. technologist plant No.156.
Item 7 Plumage. The stabilizer and the elevators are made for the serial car on the plane 103U, with the lifting mechanism, unchanged. (!) On an experimental Tu-2 №100716 keel was made of this Directive.
If you read this book, there is very detail the process of operational development of the aircraft just an example board №100716 But (!) Not a single word about the capacity of the keel. I know of no picture TU-2 graft of keels, except of experimental platform "713", "714", "716" and "718", and after the war samples.
Yes, and the drawings in this book does not inspire confidence. Especially hereinafter have upomenaniya of Tu-2 №100716, given to the state of the Tu-2S Ie from production aircraft
it is no different. And again, all the photographs №100716 seen snandartnye keels. From where the author took about graft keel mystery. (and drawing it is not very convincing)

Hi,
now I am confused.
The standard keel is of high or low type? Nearly all the drawings of Aviakollectsia show an high type on profiles, and low type only on prototypes and maybe on very early planes,
Is the keel of Tu-2D an even taller one?

Все кили Ту-2 периуда 2 мировой имели стандартный киль без изменений с тип 103U до последующих модификаций. Исключения Ту-2Д (всего 4 самолета) А вот Ту-2 образца 1946 года имели высокий киль.
1- прототип
2- Ту-2 серийный
3- Ту-2Д
4- Ту-2 обр 1946 года

I do knowingly led the comparison. 1 and 2 of the photo - matching angle 98% and the size of the image too. Visible differences between the military and post-war model. A photo 3 just discussed in the first post plane. Angle slightly disrupted but clearly videm keel that is the same as on the production aircraft.

Hi All,
thanks a lot for your imputs. I wonder how many differences there is.
My understanding is that (in some extent) size/shape of the vertical stabilizers were same (pict 3 above). And in 1946 it was increased (pict 4 above).
According to those drawing the vertical stabilizer in my profile should be OK.

It looks like I have to make another war-time and after-war profiles really fast to have a time to discus/correct them.
Thank you agan.
