1) This is Pe-2 M-82 (sample 1943)
2) The first prototype of the VI-100 was modernized from high-altitude fighter in dive bomber, after which
received the designation PB-100. It was supposed to build a small series of 30 aircraft (by the end of 1940) (No pressurized cabin and turbochargers.)
3) DB-108 preliminary design ...
Thanks a lot. :D I can see pressure tight dome shape front bulkhead in VI-100 picture.
What is the meaning of VI and PB. VI is high altitude interceptor? PB is dive bomber?

NIAI RC-I (РК-И)
https://civilianmilitaryintelligencegroup.com/22601/the-niai-rk-i

http://www.airwar.ru/enc/xplane/rki.html

http://translate.google.fr/translate?hl=fr&sl=ru&tl=en&u=http%3A%2F%2Fwww.airwar.ru%2Fenc%2Fxplane%2Frki.html&sandbox=1

"In 1938, in order to establish a world record speed. Bakshaevym RK has developed a new aircraft project with engine M-105. The estimated speed of the aircraft was 780 km / h. The project was approved, and at the end of 1938, the People's Commissariat of Aviation Industry was issued to establish the terms of reference of the aircraft in Kazakhstan single-seat fighter version of the engine M-106 and a design speed of 800 km / h. Fighter has received the designation RC-I (RC-800). "

Dictator Joseph Stalin is intrigued about this plan, starts trial of the real airplane. In 1938, on Stalin's orders, was to be equipped with more powerful 1,600 HP aircraft engine developed in VK-106. This plane is remodeled, was completed at the beginning of 1940. Without, however, to complete the engine this plane could not fly.

"Design, but not built version of RC-I with two engines and two screws front and rear of the tail. Such an embodiment of a radically increased the speed to the already extremely high-speed RC-I. "

Following picture shows wind tunnel model of RC-1, because it had no radiator at rear fuselage side.

Hi! Kostikov 302 and 302P.
http://testpilot.ru/russia/bisnovat/302/302_e.htm
"By 1940 the idea of the PVRD (ramjet) was familiar in the Soviet Union, mainly to boost the speed of piston-engined fighters. In 1940 Professor Mikhail Tikhonravov, on the RNII staff, had the better idea of making a simpler and lighter fighter with a ZhRD (liquid-propellant rocket) in the tail and PVRDs under the wings. This could put together various things already developed in the Soviet Union to create what might have been a cheap and quickly produced fighter which, apart from short range and endurance, would have had outstanding performance. Unfortunately, perhaps because it appeared unconventional, this project suffered from endless argument and foot-dragging, finally falling victim to a decision to abandon all such aircraft."

"By spring 1943 two 302 aircraft were almost completed. Testing in the T-104 tunnel at CAHI (TsAGI) began at this time. In 1943 the original proposed ramjets were changed to a new design by Vladimir Stepanovich Zuyev. These were initially tested in a half-scale form, but full-scale testing was never carried out.After much argument it was decided to forget the ramjets and complete the aircraft as the 302 P (Perekhvatchik, interceptor) with the rocket only. The PVRD attachments under the wings were faired over, and the wing span reduced."

I want to know estimated range of 302 interceptor.

Unknown Project,a helicopter driven by electric motors designed by Mr. Andronik Ghevondovich Iosif'yan,
here is in Googletranslate;

Eiactrotransicopter A.r. Iosifyana
In the early 30's. Andronik Ghevondovich Iosif'yan, subsequently
Academician, worked on the creation of an electro-helicopter
- a helicopter driven by electric motors
From a current source on the ground or on a
The device itself.
In 1933-1935, he built a model of the "electro-helicopter"
Coaxial scheme with the following parameters: diameter of coaxial screws 1.8 m,
The take-off weight of the model is 28 kg, the power plant is three-phase
Asynchronous electric motor with a power of 0.52 kW with power
From a normal 220 V power supply network through a flexible
cable. Comprehensive tests were conducted that allowed
Go to a larger model of the same circuit with a diameter
Screws 6 m and with an electric motor capacity of about
30 kW. But this model still could not lift a person.
At the beginning of 1937 a model of a tethered electro-helicopter
With three-blade bearing boltless screw
Diameter of 11 m. At the ends of the blades were electric motors
Power 8 kW and weight 8.3 kg with pulling screws
With a diameter of 0.4 m. The rotor revolution number was
Approximately 75 per minute, the take-off weight of the model with the pilot -
320 kg. In May-June 1937, ground tests were conducted,
And on June 8-9, ups to a height of 1 m. At revs
Rotor up to 45 rpm model worked fine, but
When the rpm was increased to 75 rpm, vibrations began
Sleeves and sharp jerking of the control knob. During the tests
There was a breakdown of the model when landing, so the program
Tests could not be completed.
In 1941, work was done on the alteration of the helicopter
TsAGI 5-EA, consisting in the replacement of reciprocating engines
M-2 two specially light-weight electric motors
For 200 liters. With., Built specifically for this purpose,
And in partial modification of the main reducer. Power of electric motors
Was carried out by a special mobile power station
Through a flexible armored cable large
Length. In the middle of 1941, tests began. It was performed
A number of flights to a height of several meters and flights to
A small circle. Since the beginning of the war, work on the tethered
The helicopter was discontinued and no longer resumed.

I saw a drawing to this MAI backpack glider,but where ?.

Knapsack saver MAI
In 1935 in the MAI was developed a backpack glider (wings
For the planning of the parachutist of the construction N.S. Smirnova).
Structurally, the glider was telescopic
Folding pipe forming the leading edge
Wing airframe, with swivel washers at the ends. Turn Axis
End washers coincided with the axis of the pipe. From the front
Edge of the pipe, which was attached to the pilot's shoulders, flexible
Sheathing of the wing went to his feet, forming in the plan a triangular
Wing with a vertex cut at the pilot's feet. Wingspan
2.2 m. The end washers are triangular in size 0.35 x
0.33 m were handles, for which PILOT kept and managed
Flight by installing the end washers with respect to the flow
Air at various angles of attack.
For the first time experienced the knapsack glider head of the pate
Service of the Air Force Research Institute G.A. Schmidt, it happened on April 17
1935. After jumping from an U-2 plane from a height of 1500 m at a speed
72 km / h, G.A. Schmidt made a planned flight duration
45 seconds, during this time the test pilot flew
The horizontal distance is more than 1 km. At an altitude of 600 m
Using the end washers, he folded the telescopic tube, translating
Glider in a convenient position for opening the parachute.
Then, opening the parachute, he made a landing.
Krishna for planning the parachutist became a prototype
Modern paragliders.

Several related developments are also being conducted in 1935-1936.
1) paratrooper V. Kharakhonov / Military engineer Gantman and parachutist (skydiver) Levski worked on the design of the wings. /
2) paratrooper Sergey Sanfirov / participants wings of the parachute construction of Mikhail Koptev /
3) paratrooper Boris Pavlov-Selivansky with wings of his own design

Hi!
Cockpit ceiling slide rear direction?
I can see door for rear crew under the fuselage.

Yes I think so. Seems to remember that plane was presurized ? hence the heavy framing of the canopy, and you can see the presurized crew sell behind the nose canons on one of the picts you posted.
Btw, nice scaleplan, didn't had that one at the time...

Oh pressurized cockpit!! You are sharp eyed,too.

https://www.reddit.com/r/Warthunder/comments/4j3nn2/a_soviet_bf110_petlyakov_vi100_the_supercharged/

"an aerodynamically-clean all-metal monoplane with turbo-supercharged engines. Constructed using light alloy stressed skin the VI-100 had electrical servo-motors in the flying controls and automatic adjustment of the gunsight with angle of attack, as well as pressure cabins for pilot and radio-operator/gunner, and an extensive 28V DC electrical system. Originally intended to carry a 3in calibre gun with 24 rounds in a drum, the large calibre gun was replaced by racks under centre-section to carry 100(220 lb),200(440 lb) or 500 kg(1,100 lb) bombs as well as two ShVAK and two ShKAS in the nose and a handheld ShKAS on a flexible mounting in the rear cockpit"
