Borovik, could you give somo details about that Er-2 version powerplant?

The designation is E-3130?

Thanks in advance,

Antonio

I think that front engine is ACh-30B piston engine and rear engine is Lyulka Two-stage centrifugal compressor Turbojet engine RTD-1/VDR-2 or axial flow compressor Turbojet engine S-18/VDR-3. Each engine have turbo charger?
But I can't understand how to use these turbochargers.

Since they were discussing the XFR-4 Super Fireball, that "Model-2885" would be a typo for the Ryan Model 28-5.

Hi! VRDK compressor pictures.
http://testpilot.ru/russia/mikoyan/i/250/i250_1_e.htm

Mig-13 Japanese wikipedia semi auto translation
"Soviet Union ordered Sukhoi Design Bureau and the Mikoyan Design Bureau to develop mixed power fighter powered by piston engine with VRDK accelerator which started development from 2/1944 to counteract German Messerschmitt Me 262.
Mig-13 prototype maiden flight date was 3/3/1945, but crashed caused by damage to the horizontal stabilizer in 5/7/19457/5. Flight test continued by No.2 prototype which modified vertical stabilizer and rolled out in 26/5/1945.
In flight test, powered only by piston engine, maximum speed was 677 km/h, while the VRDK operating speed improved up to 825 km/h. However she could fly only 10 minutes at this speed. Soviet Union decided to order 50 aircraft. Design Bureau completed 9 aircraft until the air show in 7/11/1945, but the air show was canceled because of bad weather.
However, production was discontinued after 16 aircraft production because need for power mixture aircraft decreased from the advent of flooded into Germany's Jet engine technology to the Soviet Union by the surrender of Germany and realization of MiG-9 and Yak-15 which developed by German jet engine technology.
Completed 16 aircraft deployed to Naval Aviation of the Baltic fleet and the northern fleet and was decommissioned in about 1950, but not went to the mission."

"This powerplant was combining the M-30B diesel engines with quasi turbojet boosters which were to be used in certain flight modes.
There was no mechanical connection between the piston engine and booster's compressor, the latter was driven by a turbine using the energy of the diesel engine's exhaust gases. Each of the two M-30Bs was to be fitted with two such air breathing boosters.The auxiliary installation was expected to produce a thrust of 850kgp(1,870lbst) at a flight speed of 800km/h(497mph)."
Also M-30B had power recoverly turbine same as pure turbo compound engine?

Source : UNFLOWN WINGS, Soviet/Russian unrealised aircraft projects 1925-2010, YEFIM GORDON and SERGEY KOMISSAROV

Sorry I made a big mistake again. It's not turbocharger.

So when take off, use VRDK booster without M-30B engine power recoverly turbine operation?.
When cruise, use M-30B power recoverly turbine only?(same as turbo compound engine?)
When dash, same as take off?

I can see shut off valve in diesel engine exhaust gas duct to front turbine and rear turbine. Use these shut off valve to change engine operation mode?

This aircraft also had quasi jet engines. Compressor of this engine was driven by turbine which driven by diesel engine exhaust gas.

The engines which located wing were ramjet engine. Diesel engine exhaust gas to the ramjet engine increase ramjet engine pressure.

Compressor of this quasi-jet engine was driven by air cooled radial piston engine which located each engine nacelle.
Fuselage is too slim to accomodate piston engine which supply quasi jet engine compressor drive power.

Almost same concept.

Projects plane with VRDK development TsAGI and other OKB.
I - 250 (MiG-13)

sources:“Samolety mira” = (Planes of the world) 2/1995
“Aircraft creation in USSR (1917-1945) Vol. II” Publishing division TsAGI 1994
"Aviatsiya & Cosmonautic" magazine
L 250 (Mig 13) a auxiliary compressor "jet engine" (CJE) to act as a booster. The CJE compressor was rotated by the M-107A prop engine using a shaft., so not a pure jetengine, Same with the Su-5 .
Caproni-Campini CC-2 was a"pure" jet engine.
