See IP-2 (DG-54)... almost Spitfire!
And a brief history:
Grigorovich designed this project in the end of 1935 / 1936 beginning; during 1st half of 1936 the full-scale mockup was built at Zavod No.1, design engineering was finished, and construction of 1st prototype parts started. But then reorganization came. On May 11, 1936 the Council of Labour and Defence (Совет труда и обороны - STO) decreed specialization of aircraft factories and chief designers' "binding" to those of them which produced their aircraft. The Grigorovich team (25-30 engineers) was transmitted from Zavod No.1 to TsAGI Prototype Constructions Factory (Завод опытных конструкций (ЗОК) ЦАГИ - ZOK TsAGI), while IP-2 construction was transferred to Zavod No.135 in Kharkov where IP-1 was produced. And half a year later, when production program for 1936/37 was refined, IP-2 was excluded from it. The reason was that Polikarpov proclaimed 520 km/h speed for his I-16bis (1937 model), and it was regarded "better". But Polikarpov never achieved such performance with I-16 in reality...

Technical data for IP-2 (calculated):
 Wing span - 11.0 m
 Length - 8.065 m
 Wing area - 20.6 m2
 Empty weight - 1430 kg
 Takeoff weight - 1952 kg
 Crew - 1
 Powerplant - one Klimov M-100A (licensed HS 12Ycrs), 860 hp
 Maximum speed - 442 km/h (at sea level), 519 km/h (3000 m altitude), 515 km/h (5000 m altitude)
 Landing speed - 120.5 km/h (102.5 km/h with flaps)
 Climbing to 5000 m - 6.0 minutes
 Service ceiling - 9900 m
 Flight range - 600 km (normal), 1180 km (maximum)
 Takeoff run - 120 m
 Landing run - 280 m
 Armament - one 20-mm ShVAK motor-cannon, 4x 7.62-mm ShKAS machine guns (wing-mounted). Attack version was also projected; it would have 10 wing-mounted ShKASes and carry 40 kg bomb load.

At the moment it is not proved, until we see the book. And in the article Vladimir Ivanov .- "Airplanes of the world" 2 / 2000 does not mention this designation.

I'm sorry wildly well where missing the previous message. Laid schemes were published in the magazine and now claim that they appear in the book is doubtful.

I'm sorry I didn't understand: what designation do you mean now?
Простите, не совсем понял Вас: какое именно обозначение не упомянуто?

Regarding DG-57: maybe it was that famous project for "Ivanov" competition, with M-34 engine mounted over the fuselage? I never met its DG number in any source, but chronologically it could be DG-57 with high probability.
Что касается ДГ-57: может, это тот знаменитый проект на конкурс "Иванов" - у которого мотор над фюзеляжем, как у летающей лодки? Я нигде в литературе не встречал его ДГ-номер, но ведь он наверняка его имел, и хронологически это скорее всего 57-й.
Best regards,
Alexander

The confusion arose because I deleted my post (the problems of translation), frankly I do not think that it will have time to someone read, the more to answer. ))
to redstar72
Alex, the draft single-engine high-wing reco the competition "Ivanov" with signature "NR"/"HP"-rus. has no relation to the program - "BS" Средний бомбардировщик - medium bomber, which was a twin-engine DG-57.
to igor-mich
In the article "Unknown Grigorovich" - m-n "Airplanes of the world" 2 / 2000 are 3-views is the DG-57 (although does not mention this designation)
 Definitely bad news (especially for russian-speaking readers) published a book about Grigorovich fault publisher delayed ...
Good news: with the kind permission of the author Mikhail Maslov few quotations from the forthcoming book.
  Now, on the add-up: a twin-engine 'Military-passenger airplane' - (DG-57)
Wingspan (m) 22,5
The length of the line of flight (m) 14,5
Wing Area (m2) 75,0
Empty Weight (kg) 3350
Flying weight (kg) 5880
Bombs (kg) 900
Maximum speed (km / h) 410

"In late 1936 Grigorovich was working on a draft medium bomber - Средний бомбардировщикBS with two engines of the Gnome-Rhone K-14 (M-85) rated at 800 hp The crew of 4 people. Inside the fuselage provided for the suspension of 900 kg bombs. A further 400 kg of bombs into overdrive suspended under the wings. By calculating the maximum speed should be 410 km / h. The project is not implemented due to lack of industrial base. Almost simultaneously, based on the bomber's intention was to create 10-12 seats passenger plane."
Additional information from the article "Unknown Grigorovich", - Roman Grigorovich, Vladimir Ivanov .- "Airplanes of the world" 2 / 2000
"...parallel with this project Grigorovich created another version of a passenger aircraft with a "clean" wing. Reviewed machine different from the above that at constant geometrical dimensions on it, instead of air-cooled engines in the wing, two engines to be installed AM-34 liquid-cooled in the fuselage - one after another. Two coaxial rotor set in motion through a system of gears and transmissions. To place motors moved the cockpit back to 1,5 meters. "

Thanks
Dive Bomber PB-1 (DG-58)

Quote
Development of this aircraft, designated DG-58, originally started in the job to the high-speed reconnaissance (SR) in 1935 as a propulsion engine is used by the Gnome-Rhone K-14 (M-85) 800 hp Virtually immediately, suggesting difficulties with the implementation of the scout because of several competing projects (Neman, Kocherigin, Gimmelfarb, Putilov), Grigorovich emphasis on specialization has made it as a dive bomber (PB-1).
Draft PB-1 with the engine M-85 was considered at the Office of Air Force and the Red Army on Sept. 19, 1935 was approved for subsequent sale as promising. They conclude: "In view of expected good data suggest factory № 1 in every possible way to force the presentation of the layout and construction of machines".
The aircraft is also expected as a light bomber and reconnaissance (DG-58R). It was a two-seat monoplane of all metal construction. Two-spar/longeron wing with a smooth duraluminum plating, the plan had an elliptical shape, to form the front of the wing center section was bent in the form of the inverse "gull". Profile section of the wing Klark YH. Retractable landing gear repeated construction used in the IP-1 fighter. The explanatory memorandum stated that the wheels are removed half to install retractable skis.
The main design characteristics of PB-1 (DG-58)
  
Wingspan (m) 12,5
The length of the line of flight (m) 8,76
The height of the parking lot (m) 3,46
Wheel track (m) 2,4
Wing Area (m2) 24,0
Empty Weight (kg) 1,507
Flying weight (kg) 2,439
Bombs (kg) 500

Here is a set of color drawings of the IP that I drew a couple of years back.
