This is the "B" version of the previous design numbered as 181. In this case, the engine is also a motorjet, but there is not the complex system to cool the hot combustors with water/steam that can be used to move a geared turbine coupled to the propeller.
Here, simply the thrust came from the combustor's jet nozzles. There is not a turbine disc to move the compressors, so it is necessary to place a two-stroke Diesel engine in the nose to do this job.
In a separate drawing I will show the basic idea.
For this reason, the rear is now free to support a tail of the elegant "T" type.
In the wing tips is housed part of the landing gear, as in the previous version "A".
I found interesting to dress the aircraft as a Soviet fighter from 1948, just in the early jet era.
NOTE: The fuel is Diesel oil not only (and obviously) for the Diesel engine, but mainly for the thirsty combustion chambers. With the relatively high fuel quantity onboard, the very high fuel consumption of the jets can be compensated. High thrust invariably leads to reduced range.
